ARMOPRIME AS is a single-component, water-based, multi-purpose acrylic primer and moisture barrier designed for both internal and external wall and floor applications. It is ideal for priming absorbent mineral substrates such as plaster, plasterboard, aerated concrete, and brickwork before tiling, wallpapering, or applying finishes. ARMOPRIME AS acts as a reliable moisture barrier, helping to stabilize surfaces and enhance adhesion. It offers excellent penetration into most substrates, improving surface integrity and preventing premature coating failure. Easy to apply and quick drying, it is a high-quality solution for preparing surfaces in residential, commercial, and light industrial settings where durability and performance are required.
Armoprime AS is a ready-to-use water based acrylic primer brushed or rolled onto absorbent substrates and allowed to cure before the next layer.
Summary of the method in the Armoprime AS Technical Data Sheet. Always follow the full TDS on site.
Armoprime AS covers approximately 80 to 150 ml per square meter, depending on substrate porosity. Coverage is approximate and subject to site conditions.
Drying time is approx. 1–2 hours, with a minimum overcoat time of 30 minutes. Apply subsequent coatings only once the primer has cured and is scratch proof.
Armoprime AS primes plaster, plaster slabs, gypsum fiber boards, plasterboard, aerated concrete, concrete, asphalt, render and brickwork before tiling and wallpapering, on floors and walls, internally and externally. It is also the primer for Hydrolastic AS777 on porous substrates.
Yes. It can be diluted 1:1 with water for the first coat on very absorbent substrates such as aerated concrete.
Application temperature is +5°C to +40°C. Above 35°C, shade the working area and protect fresh material from direct sun and strong drying wind.
