Eco-friendly primer for very absorbent substrates
- Equalises - Primes absorbent surfaces – eg new lime plasters
- Stabilises - Primer for old porous surfaces – eg old limewash
- Breathable – Allows the surface underneath to breathe
- Exceptional Coverage of up to 30m²/l
Ambient Primer L42 regulates surfaces 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.
