Using this specific product

KILZ Basement & Masonry Waterproofer is listed here as the White version for basement walls, concrete block, and masonry. For painting, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says White; related versions can use different timing.
  • For basement walls, concrete block, and masonry, pay particular attention to surface preparation, coat thickness and ventilation.
  • 77°F (25°C) and 50% relative humidity.

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. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.

Avoid this mistake

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