We’ve put all the questions together that we’re often asked – just click on one of the topics below to see all the advice.

What is the best paint for my bathroom?

GrafClean and GrafClean Eggshell are the hardest wearing of the Graphenstone paints and the ones best suited for Bathrooms. GrafClean has Class 1 vapour permeability – so breathable.

What is the best paint for my kitchen?

GrafClean and GrafClean Eggshell are the hardest wearing of the Graphenstone paints and the ones best suited for Kitchens. GrafClean has Class 1 vapour permeability – so breathable.

What is the best paint for my kitchen cupboards?

GrafClean Eggshell is the most suitable product for use on Kitchen cupboards and woodwork generally. Please note it is a flat eggshell finish. Graphenstone do not manufacture Satin or Gloss paints – In some cases a paint with a higher sheen may be more practical if a very high level of wear expected.

For the best adherence and longevity of product, use Four2Four primer onto bare or pre painted (de-greased, clean, and well prepared) surfaces.

Which is the best paint for exterior use?

On new natural Lime renders, use either Biosphere or GCS Exterior. Onto standard renders, brickwork, or previously painted surfaces, use GrafClean or GrafClean Eggshell for areas of highest wear and plinths.

Which is the best paint for woodwork?

GrafClean Eggshell is the best paint for woodwork. For the best adherence and longevity of product, use Four2Four primer onto bare or pre painted (de-greased, clean, and well prepared) surface.

Can I paint my children’s bedroom with your paint?

Ecosphere Premium and GrafClean are certified as ‘Toy Safe’ under UNE-EN 71-3;2013 and A3:2018 – TOY SAFETY.

Graphenstone paints are made using natural minerals and contain no toxic chemicals. It is one of the most tested and certified paints available.

What primer should I use on Plasterboard?

Onto bare plasterboard, first use Nevada Ultra diluted by around 20%, as a primer/mist coat, followed by 2 coats of any Graphenstone paint. You may need to ‘spot prime’ any areas of filler first.

Do I need a primer for walls previously painted?

As with most paints, so long as the surface is clean, sound, free of contaminants and impurities, no primer should be required. If you are covering a strong colour, it may help to first paint with Nevada Ultra as an initial coat to help with coverage and opacity of the topcoats.

Some existing paints – e.g., shiny surfaces or oil-based surfaces, will require additional preparation such as Four2Four or Ambient Primer. It is always advisable to conduct a sample test PRIOR to ordering the paints.

Do I need a primer?

For best results when painting new surfaces, a primer may be required. This is to ensure adherence to the surface and to improve the lifespan of the products. Follow the simple quick reference guide below:

  • NEVADA ULTRA – New interior gypsum, lime plasters and plasterboard as a mist coat. New exterior renders – lime and cement.
  • AMBIENT PRIMER L42 – Limewash, distempers, old exterior painted surfaces. Porous brickwork, exterior lime renders.
  • FOUR2FOUR – Interior and exterior wood, MDF and non-porous materials eg some metals, plastics, tiles.
  • FILLER TX100 – Interior and exterior textured primer. Helps to even out and visually mask surfaces of differing textures eg: smooth patch repairs on an existing uneven render, new brickwork next to old. Filler can also be used to cover and fill crazing and hairline cracks < 1mm.

Why should I use Graphenstone masonry paint rather than standard Acrylic paints?

Most acrylic paints will form an impermeable layered coating over a surface. This can cause problems with the build-up of damp, especially in older and traditionally built buildings, where vapour permeability (breathability) is important.

Nearly all our paints are Class 1 vapour open, meaning they are highly breathable.

Can I use your paints on exterior wood?

GrafClean Eggshell is the best option for some exterior wooden surfaces, and it has been used successfully of windows and doors. Please note it is a flat eggshell finish (Graphenstone do not manufacture Satin or Gloss paints). In some cases a paint with a higher sheen may be more practical if a very high level of wear expected. A matt surface will pick up dirt more easily (dirt slides off a shiny surface) and will be affected by UV more quickly (it will reflect light away less) so bear this in mind.

Can I paint my shed using Graphenstone paints?

Graphenstone paints are designed originally for use onto mineral surfaces like plasters and renders although with the correct primers they can be used on wood. GrafClean Eggshell is the best option for some exterior wooden surfaces however, please note it is a flat eggshell finish (Graphenstone do not manufacture Satin or Gloss paints). In some cases a paint with a higher sheen may be more practical if a very high level of wear expected.

It is important to check whether any exterior timbers have been tanalised or treated with preservers. Some pre-treatments can often reject paints and can cause staining.

Can I use your paints on my fence?

Graphenstone paints are designed originally for use onto mineral surfaces like plasters and renders, there will be limitations to using it onto rougher sawn fence panels which may well need a more resilient stain or coating.

Can I paint outside at any time of the year? What is the minimum temperature application for your exterior masonry paint?

During the autumn and winter months the days shorten, temperatures start to fall and moisture in the air increases. This will influence and increase the time taken for paints to dry and cure. Our paints are designed to be used between 7-40 degrees C.

It is our advice to avoid decorating externally between October and the end of March using Graphenstone paints.

Water dilution – how much and why?

Graphenstone paints require diluting with clean water.

WHY?

Our paints are delivered around the world. By reducing the quantity of water added to the base paints, it enables us to increase the amount of actual product delivered (not the additional water content) and reduce our global carbon footprint.

Our paints are up to 70% solid content, where most other brands, typically contain between 25-40% solid. A little clean water added, will not affect the performance of the paints, and will help you with application.

ONTO MINERAL SURFACES

  • 1st coat 10-20% (100 – 200ml of clean water) per litre of paint
  • 2nd coat 5-15% (50 – 150ml of clean water) per litre of paint

ONTO WOODWORK

GrafClean Eggshell can be applied with a dilution of 5-10% maximum, to ease application and for finish.

NB: The above quantities are intended as a guide and can depend on substrates and conditions.

Some primers differ so do please refer to the TDS (technical data sheets), or the QR code visible on all paint pots.

Useful Tips & Advice

Have a look at the link to our online tips page.

What is the best product/s to use in a damp mould area?

Graphenstone paints, being breathable, will allow passage of water vapour through them. The Lime based paints, being a naturally high pH, will resist mould and mildew growth as well as acting as a natural preservative.

For paint to successfully adhere and cure however, surfaces need to be dry, clean, sound, and free from any contaminant – eg: mould.

What are your coverage rates?

Graphenstone paints will generally cover between 10-16m2 per coat, per litre of paint applied.

Some paints and primers do differ so please refer to the TDS (technical data sheets), or the QR code visible on all paint pots.

Can your paints be sprayed?

Being a heavier mineral, our paints spray well. You will need to test on site – there will be different pressures, tip sizes, dilution rates to consider – to find the perfect balance for your system.

Onto a new un-painted mineral surface, apply a first coat of around 20% dilution followed by 1-2 further sprayed coats if needed.

Contact the office for more information if needed.

Which primer do I need for:

  • NEVADA ULTRA – New interior gypsum, lime plasters and plasterboard as a mist coat. New exterior renders – lime and cement.
  • AMBIENT PRIMER L42– Limewash, distempers, old exterior painted surfaces. Porous brickwork, exterior lime renders.
  • FOUR2FOUR – Interior and exterior wood, MDF and non-porous materials eg some metals, plastics, tiles.
  • FILLER TX100 – Interior and exterior textured primer. Helps to even out and visually mask surfaces of differing textures eg: smooth patch repairs on an existing uneven render, new brickwork next to old. Filler can also be used to cover and fill crazing and hairline cracks < 1mm.

How many coats of paint do I need?

Our paints have a very high solid content usually only requiring 2 coats onto a painted or primed surface. Some challenging colours – strong reds, greens, yellows –may sometimes be require extra coats to achieve a full depth of colour.

Can I use Nevada throughout house / instead of the more expensive products?

Nevada Ultra is an economical, mineral based matt emulsion. A low cost, breathable paint, with Class 2 durability and a lightly wipeable finish – similar to a contractor matt. Suggested areas of use are as a mist coat onto new plasters, or as a ceiling paint, where durability is not required. Colour range is limited to Whites and 6 standard colours – please contact the office for availability.

Painting on to Radiators?

Graphenstone paints are not designed for use onto radiators.

Painting on to walls where wallpaper has been removed?

Where a covering like a wallpaper/lining paper has been removed, you need to make sure all adhesive residue has also been removed to avoid a crazing/cracking of the paints on redecoration. Some old starches could react with the natural mineral bases, so please make sure your surface is fully clean and free from anything that could affect redecoration.

Painting furniture/ upcycling?

Using Four2Four primer as a bridging coat will enable you to paint onto a variety of surfaces. If painting onto furniture, your number 1 enemy could be wax which is designed to repel water! You need to make sure you remove this before applying a water based paint…

If painting onto a varnish – either remove if possible, or sand the surface well to achieve a better key for the paint to stick to.

Use GrafClean Eggshell as your furniture paint. You may need to further protect horizontal surfaces with a protective coating dependant on the level of use. We have found that Polyvine varnishes do work well if needed!

Due to the low sheen finish of GrafClean Eggshell, we do not advise it would be the best paint to use on exterior or garden furniture. A paint with a higher sheen will be more suitable!

Can you advise how much paint I need?

The coverage rates of Graphenstone paints can differ slightly so as a very general rule of thumb, allow 10-16m2 per litre of paint for a smooth surface in good condition. Substrates can differ in texture and absorbency, so sometimes more paint or an additional primer might be needed. A rough surface can dramatically increase the total surface area, a porous surface can absorb paint more quickly. In both cases allow for more paint!

It sometimes helps to allow a little over – it is common to allow for 10% over to be on the safe side.

Are your paints hardwearing?

Thanks to the graphene, we can manufacture a natural mineral based paint system with Class 1 durability.

All our paints have been tested to EN 13300, a system of wet scrubbing tests, and all achieved Class 1 once cured.

As with all paints, the cure time is not just the drying times and even latex paints can take up to 30 days to fully cure.

Graphenstone paints cure naturally. Allow 2-4 hours between coats and 24 hours for full drying.

If using outside or in an area where moisture is present (including kitchens, bathrooms, showers) please protect from rain, condensation, and water for 4-5 days from fully dry, to allow the paints to initially cure. Please note, some stronger colours may need longer to cure due to increased amounts of pigmentation used.

Full cure of our paints is achieved in around 30 days, after which they are durable to Class 1! Avoid rubbing or cleaning during this time.

Which is the most CO2 absorbing paint?

Biosphere is the paint with the highest CO2 absorption and will absorb up to 5.5kg per 15L of paint used. Ecosphere and Ambient Pro + also absorb CO2 as they cure (the majority in the first 30 days) ; 4.9kg and 5.0kg per 15L of paint used, respectively.

Do all your paints absorb CO2?

Lime, as it cures, will absorb CO2 as part of the Lime Cycle.

Only our purest lime-based products including our paints, Ecosphere, Biosphere and Ambient Pro +, absorb CO2 as they cure (the majority in the first 30 days).

Are your paints MIT free?

All Graphenstone paints are MIT free. Methylisothiazolinone (MIT) and Methylchloroisothiazolinone (CMIT) are common preservatives are found in many liquid personal care products, and have been linked to lung toxicity, allergic reactions, and possible neurotoxicity.

Is your paint vegan?

We are currently looking into Vegan accreditation.

In regard to animal testing, our paints are Cradle to Cradle certified, one of the highest environmental accreditations available.

We do not advocate or promote animal testing, and as far as Graphenstone are aware, we do not use any products in the paints that has been tested on animals.

Are Graphenstone paints VOC free?

VOCs include both man-made and naturally occurring chemical compounds and are present in the surrounding air, so in theory, nothing can be 100% free. Graphenstone paints have less than 0.1%/L or less than 1g/L in their natural mineral bases.

Are Graphenstone paints non-toxic?

Yes. Graphenstone paints have been awarded Cradle to Cradle Gold, Silver and Bronze certifications for their paints. Each certification level represents increasingly rigorous achievement across five critical performance categories: material health, material recycling, renewable energy, carbon management, water stewardship, and social fairness. The material health category uncovers every single chemical component and tests to 100ppm (100 parts per million) to ensure products are made using materials that are as safe as possible for humans and the environment.

From 2020, all paints produced by Graphenstone are also chemical preservative-free, one of the first companies in the world to achieve this.

Are Graphenstone paints eco-friendly?

Yes. Our paints are made from natural, sustainable minerals and ingredients, including natural plant-based resins. Lime, as it cures absorbs CO2 from the air, therefore helping to capture carbon as part of the natural “lime cycle”.

The manufacturing process is powered entirely by renewable energy. The factory reuses the wastewater from production, and the containers they are supplied in are 100% recycled plastic which is also 100% recyclable. The paints are also completely free of microplastics.

Acrylic paints, when used in outdoor environments including buildings, road markings and boats can release plastic particles as they degrade ending up in waterways, our oceans, and our air. When you wash paintbrushes and rollers these tiny plastic microbes that can easily transfer into the watercourse, and then into the ocean, harming wildlife.

Do Graphenstone paints have a strong odour?

None of the paints has a strong odour at all. The pure Lime paints do have a natural odour; however, this is the non-toxic smell of a natural product.

Why is lime-based paint so special?

There are many advantages to using Lime paints. They are natural and it is a sustainable mineral. Lime, as it cures, absorbs CO2 from the air, therefore helping to capture carbon as part of the natural Lime Cycle. Having a naturally high pH of around 12.5, it will naturally resist mould and mildew.

How do I recycle my used pots?

Our pots are made using 100% recycled plastic and are recyclable. Once dry, most paint tubs can be disposed of in general waste – however, please consult your local authority guidelines before disposing of any paint waste or old paint tubs.

Do you Colour Match?

We offer both the NCS colour range, (980 Interior and 322 Exterior Colours) and RAL as well as being able to offer a bespoke colour matching service.
Sample pots in any colour not shown on our own Colour Card and bespoke Colours and colour matches can be ordered. Please contact the office for pricing.

We advise ordering samples for testing on site PRIOR to ordering the paint!

How white are your whites?

All our un-tinted white paints are all pretty white. We would not say a ‘Brilliant White’ as this can sometimes be a little blue and cold – more a soft, natural white.

Which of your white paints is the whitest?

Ecosphere and Biosphere are the purest limes, so will be the ‘purest’ whites. Next will come Ambient Pro+ and GrafClean for walls, with GrafClean Eggshell for high traffic areas and wood.

Can all your colour paints be tinted?

We have different bases for our colour paints. We test every colour before it leaves the UK factory however, there can be slight variables between batches and individual product ranges. We sometimes use a different set of pigments for the Lime bases and the exterior paints; however, all colours are well within tolerance.

I want to paint my walls and woodwork in the same colour.

You can use GrafClean for walls and GrafClean Eggshell for the woodwork. Bear in mind that even though they will be the same base colour, the low sheen of the Eggshell can make the colour appear slightly lighter due to light reflectance. If you wanted an even more durable finish for the walls, you could paint all surfaces in GrafClean Eggshell.

Can I use any of your colours outside?

There will always be certain limitations to using some stronger, more intense colours externally and Graphenstone are no different. We use 2 different sets of pigments in our paints.

  • Universal pigments – for both interior and exterior application and a full range of colour choices
  • Metal Oxide pigments – mainly used in higher pH products and, for improved exterior stability – with a far more limited range of colour options.

Stronger, bolder colours – reds, yellows, greens – can be used outside (in GrafClean), however, the pigment formulations required to produce these brighter shades can be affected more by sunlight over time.

Are your whites all the same?

The different based paints – Limes, GrafClean, GCS – are all slightly different base materials so there is a slight variation as to ‘how white’ they are. For the purest white, choose the limes, Ecosphere for Interior or Biosphere for exterior.

Which paint is the most matt?

All our paints are matt – even GrafClean Eggshell, our ‘shiniest’ paint is not that shiny! They range from 1% – ultra matt, up to 25% – an eggshell type finish.

  • Limes – 1% sheen
  • GCS– 2% sheen
  • GrafClean – 3% sheen
  • GrafClean Eggshell – 15% in colours (flat eggshell) to 25% in whites

Do you tint to any other colours than is shown on your colour card?

Graphenstone uses a colour range called NCS (Natural Colour System), with over 1000 colours for interior use and over 300 for exterior use. The Limes are, being a very white base, limited to fewer colour options – currently 14 – however, GrafClean is our most diverse, with over 900 NCS colours to choose from, as well as RAL and bespoke and colour match options available if needed. For the full NCS range, please contact either your nearest local stockist or get in touch with the office.

Can I return coloured paint?

All our colours are mixed to order so I am afraid, once tinted these cannot be returned. For white paints, please consult our Terms & Conditions, for details on returns.

Burnishing

Some darker or more highly pigmented colours in all paint brands can mark more easily than lighter colours and more pastel shades. The darker the colour, the more this marking can be noticed – especially in a matt or low sheen paint. This often shows up as a light/chalky mark appearing on the surface of the paint where it has been rubbed and is generally due to the way pigment and light react. This is often referred to as ‘Burnishing’.

Colours with higher amounts of pigment can take a little longer to cure than pastel shades –the amount of pigment can slow this process down – so do allow extra time for your paint to fully harden and cure.

Some burnishing marks can be removed with a mild cleaning solution and a cloth, however, it may pay to use a paint with a higher sheen level in the highest traffic areas to minimise this problem or use a further protective coating, such as a varnish, over the top.

Graphenstone paints use natural minerals and raw materials rather than some of the more toxic chemical additives to speed curing processes up.

Graphenstone paints cure naturally!

Allow up to 30 days for your paint to properly harden and cure – sometimes this might be longer for darker shades. In the highest traffic areas, consider using GrafClean Eggshell as an alternative. Its slightly higher sheen level (around 10-15%) may prove more resistant to the effects of burnishing.

What are the ’Sd’ (breathability) values of various products?

Our paints are highly breathable and are ‘Class 1’ with the following ’Sd’ values for water vapour permeability:

  • Ambient Pro + /Ecosphere/Biosphere < 0.01 (LESS THAN)
  • GCS Interior/Exterior < 0.08
  • GrafClean < 0.1
  • Nevada Ultra < 0.1
  • Ambient Primer L42 < 0.1

How does our paint Purify the Air?

Lime will absorb Carbon Dioxide as it cures, helping to clean the air of harmful gases.

Our most air Purifying paint is Ambient Pro+, which thanks to its unique lime and mineral composition, will also help to continually eliminate pollutants and contaminants including Nitrogen Oxides, Sulphur Oxides, Carbon Monoxides and VOC’s as well as CO2.

It does this by oxidation and thanks to a natural chemical reaction with light.

How long before I receive my order?

We aim to deliver on a next day service with all our paints delivered by Courier. Orders need to be placed BY 11am, to allow for the order to be processed, mixed, and packed to be with you on the following working day.

Some postcodes eg, N. Ireland, Highlands and Islands, and some larger orders and pallet deliveries may take longer.

Which Couriers do you Use?

We use APC for Small boxed items, Palletways for larger orders and occasionally DHL.

How will I know when delivery will be? (Boxed items)

If when placing your order you supply an email address or mobile number on the day of delivery you should receive a notification of you consignment number and a 2 hour window for delivery.

The delivery slot is a guide only as many factors can cause delays.

If you are NOT going to be home for delivery please notify the office on placing the order of details so this can be relayed to the courier.

How will I know when delivery will be? (Palletised items)

All orders placed before 11:00am as sent on a next working day service. On the day of delivery someone must be available to sign for the goods. If a specific date is required please notify the office on placing your order.

Why are our tubs plastic?

Lime paints have a higher pH than standard paints and as a result can, over time, start to corrode some metals. Plastic by contract is unaffected.
Our sample pots are metal. However, we produce these in smaller batches by hand, in our UK warehouse, thereby ensuring they are not on the shelves for too long to be affected.

How long do your paints take to dry?

Graphenstone paints are touch dry in around hour and fully dry in 24 hours. Being natural, healthy, and free of chemicals, our paints do also need 3-4 days from initial drying, to start to cure so they do need to be protected from rain, and excess moisture such as condensation in a bathroom or shower room. Avoid rubbing and cleaning of the newly painted surface until this initial curing process has taken place.

Difference between Limes/GrafClean/GCS

Limes – our purest lime. If you want the healthiest, most sustainable paint with Carbon capture. Ultra-flat matt and for use in rooms with the least traffic. Colour range limited to 14 pastel shades.

GrafClean – a mixed mineral. For the greatest colour choice and most washable of our paints. Perfect for busy homes.

GCS – our lime mix, best suited for use on natural plasters – perfect for Heritage and older, listed properties. More limited colour range with some stronger colours not available.

Will your paints cure mould?

Our Lime paints are naturally resistant to mould and mildew having a higher pH than standard coatings, however, you will also need to make sure your room is well ventilated and has sufficient extraction. If you have an existing issue with mould, you will need to kill and clean what is there prior to applying the paints.

How long do your paints last?

The EPD – Environmental Product Declaration – is based on a 10-year life cycle, however site specifics and how well you look after your coatings will be the 2 factors that influence and affect the lifespan.

Regular cleaning, removal of contaminants and dirt, will mean a painted surface will remain in better condition for longer. After 5 years, and depending on the area, a full inspection would be advisable and at this point – if signs of wear are apparent – remedial works should be undertaken. The key to any longevity will be looking after the decorated surface and undertake remedial works as soon as signs of wear appear.

I am getting a patchy finish

Natural mineral paints are slightly different to the more commonly supplied plastic/acrylic paints. As such, you sometimes need to adjust the way you paint to get the best out of the product.

Make sure you dilute the paint. They have a high amount of solid in the base. Adding a small amount of water will not affect the paints, but will enable you to get a more even finish and make application easier.

Apply enough paint to the surface and roll the paints out well. The heavier solid needs to be rolled out across the surface. This helps with both the finish and the opacity.

The lime paints get more solid over the first few days. As lime starts to cure, it will become more opaque or solid. Allow the advised 2-4 hours between the coats. This will help the paint layers to start to initially cure. Full opacity will often be seen after 2-3 days.

The paints smell!

Graphenstone paints have been tested to some of the most rigorous certifications in the industry. They have some of the lowest VOC emissions – less than 0.1%/kg – and have all the materials analysed to 100 ppm (parts per million) to ensure there is nothing toxic or harmful in the paint bases.

The natural lime paints do have a slight odour. This is though the natural Calcium Hydroxide and Calcium Carbonate – the main components in our paints are natural materials and it is not impossible for natural chemical reactions to take place if substrates are entirely free from a previous material – eg wallpaper paste (it is starch). A surface not fully dry or cured before you paint – EG gypsum plasters which can take a while to cure and release a rotten egg smell (hydrogen sulphate).

My paint is not sticking

If a paint is not sticking to a surface, there is usually a reason why. There is often something already on the surface that is stopping it from sticking – eg wax, or the surface is not compatible and needs a primer – eg plastic.

So long as a surface is prepared correctly, in some cases using the correct primer system, most paints will stick to most surfaces. Sand down anything that is shiny, make sure areas like kitchen walls are clean and free from grease and kitchen detergent residues.

Surfaces with a coating that is designed to be water repellent – wax, silicon – will need to be removed prior to painting.

Difficult surfaces like plastic or tiles may need a bit of extra preparation using the right primer. It will help to sand a difficult surface slightly if possible. This will open up the surface and improve the bond – there is more area for the paint to bond with.

Apply 1-2 coats of our Four2Four prior to painting. It may take a few days for the paint to properly contract, cure and bond, so on difficult plastics, you might need to leave the primer for up to a week to make sure the bond is sound. Once cured, apply Graphenstone paints over the top.

I have bits in my paint!

Our paints undergo numerous quality checks from the factory to your door. Paints are filtered in the factory as tubs are filled, and then checked at least 3 times before they reach your door – we perform quality checks as soon as the paint arrives in our UK warehouses and then every 3- 6 months. All colour paints then undergo a final check on tinting.

Our paints are based on limestone so in effect once dry return to a stone. They are not a plastic.

Our paints, due to their high pH are supplied in 100% recycled plastic tubs.

Sometimes, in transport, the body of the paint can collect around the inner rim and underside of the lids. This can dry and end up in your paints if you are not careful.

When you open the plastic tubs, try not to ‘snap’ back the lids. If there is any dried material on the underside of the lid from the transport/courier process , this could end up in your paint.

When you use the paints, make sure you keep the rims, edges and side of the tub clean – try not to allow the paint to dry – don’t just put the lids back on with drying paint collecting on the sides. This will just build up and could end up in your fresh paint!

My paint got wet and has water streaks in it

Graphenstone paints are made using natural minerals and resins, having had the harmful chemical additives often used in paints, removed. Our paints cure naturally!

The first 3-4 days after drying are crucial – during this time the paints are starting to cure. The minerals are going through the natural processes of starting to harden on your walls. If the paint is still a little delicate, rain or excess moisture can affect the surface and you can notice streaks in the paint itself.

OUTSIDE: If decorating externally, you need to keep an eye on the weather and protect from rain for 3-4 days after drying. Check gutters for leaky joints and blockages and cover any exposed areas well. Darker colours with lots pf pigment in the base can take a little longer – so be a bit more careful with blacks and stronger, bolder colours.

INSIDE: This can also happen when painting in bathrooms, or in areas where there can be a lot of moisture in the air (which can transfer onto the walls). Wait 4-5 days before introducing a lot of steam/moisture in to the room from baths or showers. This will end up on and running down your walls!

If you do get caught out, don’t just try and paint over the marks, they can show through. Wait for the surface to fully dry and apply a single coat of diluted L42 over the whole area. Allow to cure for 24 hours and then re-apply 2 coats of your chosen Graphenstone paint.

PURIFYING PAINTS

Please read any references to “low” or “zero VOCs” as “Trace VOCs, less than 1g per litre (or 0.1%), naturally occuring. We are in the process of updating this detail across the site.
