How to check readiness

Test the least-ventilated area before walking, covering or replacing furniture. Pot life is about 25 minutes; warmer than 73°F shortens pot life and working time. Non-moisture-sensitive floor coverings can go on after 1.5 to 2 hours. Try a protected edge first and avoid turning, dragging or concentrated loads.
