How to check readiness
Check the real material or treated area at the slowest location before the next step. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required. Try a protected edge first and avoid turning, dragging or concentrated loads. Open the area gradually and keep heavy or hot tires off until the full stated milestone.
Avoid this mistake
The first visible change is not always the manufacturer’s final-use milestone.
