A great way to view and understand your building or repair project before you get started. Find out just about everything you need to know by watching the video below.
The most common repairs to brick and block walls, chimneys and brick veneer are cracks caused by wall movement or foundation settling and the deterioration of the mortar joint from exposure to the element over time. Once a crack develops it is important to seal the crack from water to prevent further deterioration.
Always wear eye protection and waterproof gloves when working with polyurethane sealant and work in a well-ventilated area.
Widen the crack to a minimum of 1/4 inch using a chisel and hammer (the edges of the crack should be vertical or beveled in an inverted “V”).
Cut the tip of the nozzle on an angle with a utility knife to match the width of the crack and load into a standard caulk gun.
Slowly draw the gun along the joint forcing a bead of repair caulk deep into the crack.
Remove excess material with a trowel immediately after placement.
