CLEAN-UP SOLVENT: Water

PACKAGING: 4-Liters and 16-Liters

APPLICATION: Trowel or putty knife

SERVICE CONDITION: Do not apply product on painted surface. 

SURFACE PREPARATION:

1. Surface should be clean and dry, free from oil, grease, dirt, contaminants, and all loose grit and mortar.
2. Defects on concrete like plumbness that are more than 3mm thick should be addressed by using exterior renders.
3. Always dampen the concrete before application. Plastered walls should already be cured for at least 14 - 28 days prior to the application of a skimcoat.

MATERIAL PREPARATION:

1. Put K-201 High-Performance Acrylic Skimcoat in a suitable container and mix it with sifted cement at a 1:1 ratio by weight until a lump-free, homogenous paste is achieved. Do not add water.
2. Use Portland cement (for ordinary cement color) or white cement (to produce a white finish).

APPLICATION SCHEDULE:

1. Using a steel trowel, apply a thin layer of mixture on the surface by firmly pressing the edge of the trowel on the concrete until all areas are covered.
2. Let it dry for at least 1 hour before applying the second coat.
3. If trowel marks are visible, let surface dry for at least another hour before sanding to further smoothen surfaces. Allow at least 7 days before painting. No need to neutralize.
