Caulking Gun

Wire Brush or Angle Grinder

Vacuum or Air Blower

Clean Rags or Paper Towels

Safety Glasses and Gloves

Step 1: Safety First

When beginning a repair project, you should always start by putting on safety glasses and gloves. When you are working with PolyFlex sealant, these safety devices will assist protect your eyes and hands from any potential risks that may arise.

Step 2: Inspect the Crack

The next step is to evaluate the severity of the crack; sometimes, they are little and simple to fix, while other times, they are more widespread and demand a greater amount of effort to fix. Additionally, this will provide you with a more accurate estimation of the quantity of PolyFlex sealant that is required.

Step 3: Clean the Crack

Use a wire brush or an angle grinder to clean out the crack and remove any loose concrete, dirt, or old sealant. A clean crack will allow the joint expansion concrete repair product to bond properly with the concrete itself.

Step 4: Remove Dust

After cleaning the crack, use a vacuum or air blower to remove dust. This will further ensure a clean surface for the PolyFlex to adhere to. If even the smallest amount of dust remains, the sealant won’t be able to adhere properly, which will require repair further down the road.

Step 5: Apply PolyFlex

Load your caulking gun with KwikBond’s PolyFlex. Begin at one end and slowly move along the length of the crack while squeezing the trigger to apply the sealant. Be sure to fill the crack completely.

Step 6: Smooth the Sealant

Using a flat tool or your gloved finger, smooth the sealant. This ensures it fills the crack and is level with the surface. Wipe away any excess sealant with a clean rag or paper towel.

Step 7: Allow to Cure

Allow the PolyFlex to cure. Refer to the product’s instructions for the recommended curing time. During this period, keep the treated area clear of traffic.

Step 8: Inspect Your Work

Once the PolyFlex is fully cured, inspect your work. The repaired crack should be tightly sealed and level with the rest of the surface.
