Application Steps

Mixing: Stir Part A mechanically before use. Add all of Part B to Part A and mix continuously for 3 minutes at 300–400 rpm until uniform. Pour into a clean container and mix again. Avoid over-mixing to minimise air entrainment.
Primer: Apply Sikafloor®-161 HC by brush, roller, or squeegee. Preferred method: squeegee then back-roll crosswise. Apply two coats if needed to achieve a continuous, pore-free coat.
Levelling: Level rough surfaces using Sikafloor®-161 HC levelling mortar before applying coating.
Coating Application: Apply Sikafloor®-264 HC by short-piled roller crosswise in two coats.
Seal Coat: Apply by squeegee then back-roll crosswise with a short-piled roller.
Cleaning (Tools): Clean all tools immediately with Thinner C. Hardened material can only be removed mechanically.
Floor Maintenance: Remove spillages immediately. Clean regularly using rotary brush, mechanical scrubbers, high-pressure washer, or scrubber-dryer with suitable detergents.
