Step 1: Suit Up

Oil, grease, dirt prevent adhesion. Scrub thoroughly. Stubborn stains: soak with degreaser 20–30 minutes, then scrub. Rinse completely.

Moisture traps cause delamination. Wait until concrete is bone-dry (24+ hours in humidity).

Step 4: Test Patch

Brush coating on a small area. Confirm color, texture, adhesion. Adjust technique if needed.

Step 5: Apply Systematically

Work in sections. Follow manufacturer's spread rate and recoat window. Use roller for large areas, brush for edges. Maintain wet edge.

Step 6: Ventilate Aggressively

Door open + fan exhausting fumes. Keep airflow until fully cured.
