HOW-TO VIDEOS

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.

When working with cement-based products, always wear eye protection and waterproof gloves. QUIKRETE Concrete Repair, QUIKRETE Gray Concrete Crack Seal or QUIKRETE Self-Leveling Polyurethane Sealant may be used.

Step 1
Widen the crack using a chisel and hammer to a minimum of ¼ inch and break away any deteriorating concrete (the edges of the crack should be vertical or beveled in an inverted “v”).

Step 2
Remove loose material with a brush.

Option A: QUIKRETE Concrete Repair

Step 3a
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.

Step 4a
Slowly draw the gun down the crack, forcing a bead of Concrete Repair caulk deep into the crack.

TIP: Concrete Repair can be tooled with a trowel to match the surrounding surface immediately after placement. It will begin to form a skin in about 20 to 40 minutes and will harden completely in 1 to 2 hours.

Option B: QUIKRETE Gray Concrete Crack Seal

Step 3b
Pour the sealant from the bottle, overfilling the crack slightly to allow for settling and shrinkage.

NOTE: for cracks deeper or wider than ¼ inch, Concrete Crack Seal should be applied in multiple applications, waiting 24 hours between applications.

Option C: QUIKRETE Self-Leveling Polyurethane Sealant

Step 3c
Cut the tip of the nozzle at an angle with a utility knife matching the width of the crack and insert the tube into a standard caulk gun.

NOTE: for cracks or joints over ¼ inch, a Backer Rod should be placed in the crack before applying the sealant.

Step 4c
Move the nozzle slowly along the length of the crack, allowing the sealant to settle.
TIP: this may require an additional application, which should be done immediately so that the two applications will mend into each other.    

Step 5c
Excess sealant should be cleaned up immediately with a commercial solvent or a citrus-based cleaner.
