Natural Primer – Graphenstone Ambient Primer L44 Premium – Anti Algae

Eco-friendly, algae inhibiting primer for very absorbent substrates

  • Equalises – Primes absorbent surfaces – eg new lime plasters        
  • Stabilises – Primer for old porous surfaces – eg old lime wash        
  • Breathable – Allows the surface underneath to breath        
  • Anti Algae – Extra fungicide added for algae protection.        
  • Exceptional coverage of up to 30m²/l
  • Ideal for very absorbent substrates such as cellars, rooms without ventilation and prone to the growth of microorganisms.

AmbientPrimer L44 regulates and reduces the absorption of the substrate prior to painting. Recommended for absorbent substrates and mandatory use prior to AmbientPro+, as it guarantees the stability and durability of the photocatalytic system over time.

Coverage: 26-30 m²/L (1 coat)

If you do not require your primer to inhibit algae, please use Ambient Primer L42

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.

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!

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!
