Clean the expansion joint gaps: Use a wire brush or vacuum to remove any cell debris, dirt or dust from the bed.
Sealant slag: Choose a high-quality sealant that is suitable for joint and construction materials. Silicone sealant vapors are generally used for expansion joints because they can withstand a wide range of temperatures and remain flexible. Apply jointwar sealant using a caulking gun, ensuring the entire gap is filled.
Caulk Tools: Use tools such as a putty knife or special caulking tool to smooth and shape the caulk to create a neat, uniform look.
Allow the sealant to dry: Follow the manufacturer’s instructions for curing time, which can vary depending on the type of sealant and environmental temperature and humidity.
Get the joint checked: After the sealant has dried, get the joint checked for any gaps or parts that may have caused the sealant to shrink or pull away from the edge. If necessary, apply a second layer of sealant to fill any gaps or create a smooth surface.
