Acrylic primer for self-levelling screeds
abeprime SLC acrylic primer is an acrylic emulsion-based primer for abescreed SLC cement-based self-levelling screeds.
Uses:
For priming concrete screed sub-floors and impermeable surfaces (tiles and terrazzo) prior to the application of abescreed SLC P self-levelling screeds.
Advantages
• Improves adhesion to substrate
• Reduces surface absorbency
• Seals the substrate, preventing air bubbles migrating to the surface of the screed
Temperature & Relative Humidity
Do not apply primer if humidity is in excess of 85% @ 21 ºC or 75% @ 10 ºC.
Do not apply primer if the substrate temperature is at least 3 ºC (5 ºC is better) above dew point.
Surface Preparation
The base must be a firm and thoroughly cleaned concrete or screed. For a high degree of bond in heavily trafficked areas, use enclosed shot-blasting or grinding. All residues must be removed including vacuum cleaning to provide a dry, dustfree, open textured surface free from excessive laitance, old adhesives and other contamination. Densely troweled concrete surfaces should be similarly prepared to ensure good adhesion.
Impermeable surfaces such as tiles and terrazzo are to be abraded (diamond grinder) to remove any seals or polishes and thoroughly vacuum cleaned.
Mixing
It is always advisable to give the product a thorough stir prior to application.
Application
Apply by brush or roller at the coverage rate provided to totally cover the area. Two coats are normally required for application to concrete and to other self-levellers.
On non-absorbent surfaces, apply by roller and one coat may suffice. Brush out thoroughly to ensure full wetting of the surface. Allow the primer to dry between coats, typically by leaving it overnight but the first coat might dry in 1 to 3 hours dependent on absorbency of the base, temperature and relative humidity.
Note: Do not allow the primer to pond and ensure that it is completely dry before the application of the screed.
Coverage
5 m2 per litre per coat (0.2 litres/m2).
Two coats are recommended, for non-absorbent surface one coat may suffice.
Cleaning of Equipment
Tools, brushes and mixing equipment should be cleaned with water immediately after use and before material has dried. Dried material can be removed using abe® super brush cleaner.
