How to check readiness

Test an inconspicuous area for firmness and blocking before normal use. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath.

Avoid this mistake

Recoating too early can trap solvent or water; waiting much longer may require scuffing under the label directions.
