ARMOPRIME AC is a high-quality, single-component, water-based acrylic primer designed to deeply penetrate and waterproof a variety of surfaces, enhancing adhesion for plaster, ceramic tiles, wallpaper, and other finishes. It effectively closes pores to prevent dusting while providing excellent bonding to concrete, timber, granolithic screeds, masonry, paving, and mild steel. ARMOPRIME AC also offers resistance to diluted acids and alkalis, making it a reliable choice for both internal and external applications. It’s easy-to-apply formulation ensures integral waterproofing, long-term durability, and superior surface preparation, making it an essential primer for achieving high-performance coatings and finishes.
Armoprime AC is a ready-to-use water based acrylic primer brushed, rolled or sprayed onto the substrate, with the next layer applied while the primer is still tacky.
Summary of the method in the Armoprime Ac Technical Data Sheet. Always follow the full TDS on site.
Armoprime AC is a primer before self-levelling or fluid mortars, levelling compounds and cement-based flooring, a roughening and bonding layer before tile adhesive or plaster, and a sealer and bonding primer on AAC blocks, porous surfaces and gypsum or cement boards. It also acts as a vapor barrier against capillary humidity.
The TDS gives an application rate of 3–4 m² per liter depending on substrate porosity, and a coverage of approximately 5–6 m² per liter. Very porous substrates need two coats.
It should not fully dry: start plastering, tiling or other coverings immediately while the primer film is tacky. The recoat interval between primer coats is approx. 30 minutes.
Yes. Armoprime AC is for indoor and outdoor applications. Do not apply where ambient temperatures are below 5°C; application temperature is +5°C to +40°C.
Armoprime AC is supplied in 20 liter jerry cans and can be used within 12 months of production date if stored unopened in dry conditions away from direct sunlight.
