Preparation

Opening to be sealed must be free from frost, dust, dirt, oil, and loose particles.* Hosing and wire brushing facilitate cleaning.

Application

Insert the cartridge into any standard caulk gun. Select the size of the bead by cutting the plastic spout at your preferred measurement (five-sixteenths-inch, one-quarter-inch) on the cartridge tip. Cut the spout at a 45-degree angle and puncture the inner seal in the spout with a screwdriver. Force the compound tightly into the crack. Smooth down the patch with a wet putty knife or trowel. DRYLOK® Masonry Crack Filler is non-flammable. It should not, however, be used as a substitute for high-temperature furnace cement or fireplace mortar. Deep cracks (more than one-quarter-inch) should be filled to within one-quarter-inch of the top with oakum before filling with DRYLOK® Masonry Crack Filler.

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.
