Caulking and sealing air and water leaks in vinyl siding

Vinyl siding is available in distinctive designs and classic profiles and adds lasting beauty and value to any home. It is extremely durable and impact resistant. It will not rot, dent, flake, scratch or blister - and is virtually maintenance-free. Offered in a wide range of colors, vinyl siding eliminates the need for painting since the color is permanently saturated right through the panel. However, as with any other siding material, it does need caulking to seal out air and water. Look along the space where the window and door frames meet the siding. If you see an open crack, run a bead of non-hardening, Loctite® Clear Silicone Sealant to seal the opening.

Step-by-Step Directions

  1. Clean away old caulk, loose paint and dirt with a wire brush or rag. Puncture the tube and cut the nozzle to create the appropriate bead size.

  2. Lay a uniform bead that overlaps both surfaces for a good seal, forcing the silicone into the seam to be sealed to ensure full contact adhesion.

Tips

Loctite Clear Silicone is water and weather resistant and remains flexible to withstand movement due to heat and other outdoor conditions.
