Most Frequently Asked Questions
Our eco facts
Biosphere is the paint with the highest CO2 absorption and will absorb 5.5kg per 15L of paint used. Ecosphere and Ambient Pro + also absorb CO2; 4.9kg and 5.0kg per 15L of paint used, respectively.
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.
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.
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.
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.
Yes. Graphenstone paints have been awarded Cradle to Cradle Gold & Silver 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.
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, unlike acrylics. Acrylic paints (which most paints are) used in outdoor environments including buildings, road markings and boats release plastic particles as they degrade and this ends up in waterways, our oceans, and our air. Also, when you wash paintbrushes and rollers all those plastic particles are ending up in the ocean. These are the tiny plastic microbes that can easily transfer into the watercourse, and then into the ocean, harming wildlife.
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.
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.
What to Use Where?
GrafClean and GrafClean Mid Sheen are the hardest wearing of the Graphenstone paints and the ones best suited for Bathrooms.
GrafClean and GrafClean Mid Sheen are the hardest wearing of the Graphenstone paints and the ones best suited for Kitchens.
GrafClean Mid Sheen is the best product for use on Kitchen Cupboards and woodwork generally.
For the best adherence and longevity of product, use Four2Four primer onto bare or pre painted (de-greased, clean, and well prepared) kitchen cupboards.
On new natural Lime renders, use either Biosphere or GCS Exterior. Onto standard renders, brickwork, or previously painted surfaces, use GrafClean or GrafClean Mid Sheen.
GrafClean MidSheen is the best paint for woodwork.
Ecosphere Premium and GrafClean are certified as ‘Toy Safe’ under UNE-EN 71-3;2013 and A3:2018 - TOY SAFETY. Graphenstone paints are natural and contain zero toxins, one of the safest paints on the market.
Onto bare plasterboard, first use Nevada Ultra diluted by around 20%, as a primer/mist coat, followed by 2 coats of any Graphenstone paint.
As with all paints, so long as the surface is clean, sound, free of contaminants and impurities, no primer is 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 may be advisable to conduct a sample test PRIOR to ordering the paints.
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:
A lot of petrochemical 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.
GrafClean MidSheen is the best paint for woodwork.
GrafClean Mid Sheen is the best option for some exterior wooden surfaces, and it has been used successfully of windows and doors. Bear in mind that there will be limitations to how a matt surface will wear over those of a shiny surface – e.g., Satin or Gloss. 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.
Graphenstone paints are designed originally for use onto mineral surfaces like plasters and renders, however, it has been used successfully of windows and doors and even garden buildings.

Graphenstone paints are designed originally for use onto mineral surfaces like plasters and renders, however, it has been used successfully of windows and doors and even garden buildings, however, there will be limitations to using it onto rougher sawn fence panels which may well need a more resilient stain or coating.
The TDS states 5 degrees, although with water-based paints, as soon as you start to get to 7/6 degrees, you start to hit the dew point. It is not just temperature that can affect coatings, it is also relative humidity, and in Autumn months the relative humidity in the UK starts to creep up, which will also slow down the drying and curing process. We do not advise painting externally beyond end September/early October – my rule of thumb has always been, if you can see your breath in the air, don’t paint!
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 < 0.12
- Nevada Ultra < 0.14
- Ambient Primer L42 < 0.13
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.
Graphenstone paints require diluting with clean water.
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.
Some primers differ so do please refer to the TDS (technical data sheets), or the QR code visible on all paint pots.

For best results when painting new surfaces a primer may be required. This is to ensure adherence to the surface and also to improve the lifespan of the products. These simple rules apply: Onto Absorbent surfaces eg: Lime plaster/Render, use Ambient Primer (L42 for Interior/L44 for Exterior). Onto Gypsum plaster: No primer required, just apply a watered down 1st coat, followed by 1 or 2 coats of paint. Onto Non Absorbent surfaces and wood, use Four2Four primer, followed by 1 or 2 coats of paint. Under GCS paints, use GCS Primer (Interior/Exterior). To cover minor cracking and even out surface texture, use Filler.
Graphenstone paints, being breathable, will allow free 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.
Graphenstone paints have some of the highest yields of any paint available and will generally cover between 16-18m2 per coat, per litre of paint applied.
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 surface, I would apply a first coat of around 20% dilution followed by 1-2 further sprayed coats if needed.

Our paints have a very high solid content – so more paint is left on your walls after it dries. It also means that they often cover better than a lot of other paints – usually only requiring 2 coats – even in darker stronger colours. It is also the case though, that in the most challenging colours – strong reds, greens, yellows – that extra coats may sometimes be required to achieve a full depth of colour.
Thanks to the graphene, we can manufacture a natural mineral 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, being natural and chemical free, also need to cure and require anything from 4-14 days for initial cure, to 30 days for the lime paints as they carbonate.
Woodwork & Furniture
GrafClean MidSheen is the best paint for woodwork.
Colour & Finish
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 cost £7.80 each. Bespoke Colours and colour matches cost £14.40 each and include a 500ml sample pot.
We advise ordering samples for testing on site PRIOR to ordering the paint!
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.
Ecosphere and Biosphere are the purest limes, so will be the ‘purest whites. Next will come Ambient Pro+ and GrafClean for walls, with GrafClean Mid Sheen for high traffic areas and wood.
We have different bases for our colour paints are made in batches using natural materials. We do 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.
You can use GrafClean for walls and GrafClean MidSheen for the woodwork. Bear in mind that even though they will be the same base colour, the low sheen of the Mid Sheen 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 Mid Sheen.
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.
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.
All our paints are matt – even GrafClean Mid Sheen, 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 Mid Sheen – 15% in colours (flat eggshell) to 25% in whites
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 1000 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.
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.
ORDERING & OTHER INFORMATION
It is easy, click here to contact us.
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.
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.
Graphenstone paints are touch dry in 2-4 hours 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.
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 listed. More limited colour range with some stronger colours not available.
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.
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.
GRAPHENSTONE ON THE BBC
The Graphene Company, the exclusive UK distributor of the Graphenstone range of paints and materials, are now using high-tech machinery at the new facility to automate tinting and mixing of the ultra-sustainable mineral based paints system.
