Applications
BestPrimer AC406 is used as a primer on concrete or render surfaces before applying products such as cement-polymer self-leveling mortars, waterproofing compounds, and cement-polymer/polyacrylic/polyurethane-based sealants, etc., for items such as floors, roof slabs, gutters, rooftops, toilets, basements, etc.
Advantages
High penetration, enabling deep bonding into the material.
Easy to apply with common tools such as brushes, rollers and spray guns, etc.
High adhesion on cement-based material surfaces.
Non-toxic and environmentally friendly.
Application instruction
Surface preparation:
General requirements:
For highly absorbent and friable surfaces: up to 5% clean water may be added to BestPrimer AC406 before application.
For dense surfaces with medium roughness: do not add dilution water during application.
For power-floated surfaces: the surface should be roughened and thoroughly cleaned before using BestPrimer AC406.
Substrate conditions:
The concrete (or render) must reach compressive and tensile strengths suitable for the actual service use of the work item.
The surface must be free of standing surface water; ponded areas must be wiped dry with a clean cloth.
Impurities, debris, dust, oil, grease, moss/algae and mold, etc. must be cleaned as required.
Application procedure:
Use a brush, roller or spray gun to apply one coat of BestPrimer AC406 over the entire surface at 0.10 ÷ 0.20 kg/m² (depending on surface condition). For best results, ensure the product is distributed evenly with no missed areas.
Before applying the next material layer, ensure the primer has fully dried (transparent, hard and no longer tacky).
Notes:
Do not let the product pond on the surface. Re-check the surface 5 to 10 minutes after application. If the product has not turned transparent (still milky) in ponded spots, spread it thin with a roller or brush.
The work area must be well-ventilated.
Stir or shake the product well before use.
Cleaning:
Use water and soap to clean tools immediately after use and before the product cures.
Safety guidance:
BestPrimer AC406 is non-hazardous and non-flammable. However, it may cause irritation to sensitive skin on prolonged contact. Wear gloves, a mask and safety goggles during application.
If splashed into the eyes, nose or mouth, rinse immediately with plenty of clean water several times before going to the nearest medical facility for timely and proper treatment.
