Construction Method
Base Surface Treatment: Clean surface of dust, oil and loose particles; repair large holes; ensure base solid.
Dilution:For normal concrete, dilute 1:1 with water; for very porous or dusty surface, use undiluted; stir well.
Application: Apply 1–2 coats with roller, brush or spray; ensure uniform coverage, no pooling; second coat after first is touch-dry.
Drying & Next Step:Allow 2–4 hours drying before applying putty, mortar or tile adhesive; do not let primer dry for more than 24 hours before next layer.
