Coating for Cement Surface:
- Surface Preparation: Ensure a clean, open surface.
- Putty (Optional): Fill cavities with Bostik Patchfix Concrete/SBR mortar.
- Primer Coat: Mix 5–10% Bostik Thinner E with CTE. Apply uniformly with a brush.
- Top Coat: Mix CTE PTA and PTB (4:1 by weight). Apply two coats at 250 g/m² per coat, achieving 100-125 microns DFT.
Coating for Steel Surface:
- Surface Preparation: Sandblast to SA 2½ profile.
- Top Coat: Follow the same mix ratio and apply two coats at 200 g/m² per coat.
Application can be performed using a brush, roller, or spray.
