It has ALL the eco credentials, and Graphenstone are now the most green certified eco paint brand in the word! This natural exterior paint looks amazing in the light, soft and natural. It has great applications for both normal painting, as well as for construction, restoration and repainting. It naturally removes CO2 from the air, and helps create a healthier space inside and outside your home guaranteeing the breathability and health of the building. It can be used inside and out. This is the exterior paint to choose if you want THE best eco creds from a natural paint. Super easy to use, and excellent coverage per litre.

MASSIVE CO2 ABSORPTION! Three 15L tubs of this breathable paint absorbs as much CO2 from the air as a fully grown tree does in a year!

Graphenstone Biosphere is made from organically milled lime extracted in a eco friendly and documented way. Once you have painted the wall, as it dries it goes through the process of carbonation. During this process (in the first few days) the lime absorbs the CO2. Very clever!

Sample / Tester Pots

We offer 2 types of tester pots on most products on all pages (in the drop down box)
1) ‘Colour Tester 100ml – (Standard colour matched pot for all Graphenstone paints)’ £4.99 per tester pot. We use our premium grafclean paint to offer sample pots in all colours we offer. The colour of this tester is exactly the same as the colour in the other paint ranges, which is why we offer it as a standard tester pot (as it’s cheaper as we can use this one paint for all colours). We mix this per order.
​ 2) ‘Colour Tester 100ml – (In this specific paint to test texture or sheen)’ £7.80 per tester pot. For people who want to check the exact paint, we also offer a tester pot in the actual paint (for people who want to check texture / consistency) as the colour is exactly the same as the standard tester pot.

Large orders of big tubs will need to be sent on a pallet, so may be +1-2 working days.

3 bags - £21
4 bags - £28

ECO PACKAGING: Testers use bio degradable corn starch infill packing pieces (these are only suited to testers and very light weight items though); on larger products we either use recycled/recyclable brown paper or we’re just starting to use pulped cardboard inserts for 2.5l and 5l tins - these are recycled and can either be recycled with household cardboard, composted or several people use them as firefighters!

Add products to basket and click estimate shipping to see costs.

All weekend orders are processed on Monday morning. We always advise trying a tester pot first.

* Postal Surcharges: Channel Islands, Isle of Man, Isle of Wight, Highlands & Scottish Isles incur a surcharge. These surcharges are set by the couriers and not by ourselves! Our standard pricing (graphic, pricing) is for mainland England only, with above modifiers. All orders placed after 11am are processed morning of the next working day. Standard delivery is 3-4 working days.

Please Note: All products (paints / finishes / oils / waxes etc) are held in white and clear only, everything else is hand coloured specifically to your order (when you select from a colour range) by our wonderful mixing team, so unfortunately cannot be returned. Please please please try a tester pot first beforehand!
