Apply DRYLOK® Pourable Masonry Crack Filler when air and surface temperatures are at a minimum of 50°F. Cracks must be free from frost, dust, dirt, oil, and particles.* Wire brushing and hosing facilitates cleaning. Remove excess moisture before filling the crack. Do not apply if rain is expected within 24 hours. Shake well before using. Use DRYLOK® Pourable Masonry Crack Filler only when cracks are one-half-inch wide or smaller.


Remove the red cap and cut the tip of the spout to a size slightly smaller than the width of the crack. Squeeze DRYLOK® Pourable Masonry Crack Filler tightly into the crack, over-filling slightly to allow for shrinkage. Smooth the patched area with a putty knife. Replace the cap after use.

USAGE STATEMENT: Prior to use, carefully read the product label and follow the directions. For technical information, warnings, cautions, notices, and additional information, download and read the documentation available on this website.
