Prepare the Surface
- Clean the AreaStart by cleaning the area around the cracked paint on the caulked surface. Use a damp cloth or sponge to remove any dirt, dust, or loose particles. Ensure the surface is completely dry before proceeding.
- Remove Damaged PaintIf necessary, use a putty knife or scraper to gently remove the cracked or loose paint from the caulked area. Be careful not to damage the underlying caulk or substrate. Smooth the area with fine-grit sandpaper to create a clean and even surface.
- Protect Adjacent Surfaces (Optional)If desired, apply painter's tape to protect adjacent surfaces, such as walls or baseboards, from accidental paint splatter.
Apply TOWER Accelerator
- Load the CaulkLoad TOWER Accelerator into a caulking gun. Cut the tip of the caulk tube at a 45-degree angle to create an appropriate-sized opening.
- Apply the CaulkStarting from one end of the cracked paint, slowly and evenly apply the fast dry caulk into the cracked area. Use steady pressure on the caulking gun trigger to achieve a consistent bead of caulk, making sure you are extruding enough caulk to fill in the cracks.
- Smooth the CaulkContinue applying the caulk along the entire length of the cracked paint, ensuring it fills the gaps completely. Smooth the caulk with a damp finger or a caulk-smoothing tool to create a neat finish. Remove any excess caulk immediately using a damp cloth.

Drying Time & Finishing
