To remove latex caulk, first soften it using latex caulk remover, heat it up using a hair dryer or a heat gun, then scrape it away using a knife once it gets soft. Applying the caulk remover is simple; simply squeeze the remover onto the caulk, ensuring that all edges get covered. Then let it sit for a few hours before scraping the old caulk off.Continue Reading
Latex caulk is used to seal places such as tubs and showers or doors and windows. Scraping cracked or moldy caulk from around the bathtub can be a tough, tedious, yet delicate job that has to be done right to prevent chipping tiles or spoiling the tub finish.
The caulk remover works by weakening the bond between the caulk and the tile or tub, so that instead of having to chip at the caulk with a razor blade, you can use a putty knife to pull away big chunks. Most removers are effective for both acrylic latex and silicone caulks.
Applying localized heat with a heat gun or a hair dryer can also help weaken the bond, which makes it easy to remove big pieces of caulk. Remove the residue with soapy water and allow the surface to dry before you attempt re-caulking.Learn more about Building Materials
