DIY Caulking on a Kitchen Counter
If there's a gap or a water leak around the edge of your kitchen counter, you need to caulk or recaulk the countertop. Caulk comes in a variety of types, including latex and silicone. In most cases, you want to use silicone caulk or a mixture of the two in areas where moisture is present, such as around countertops. For best results, practice your caulking skills on the inside corners of a box before applying caulk to the counter itself. This helps you get used to caulk flow and application technique.
Use a putty knife or scraper to peel away any old caulk around the edge of your countertop. If some caulk still remains, cut it away with a utility knife.
Clean or scrub the area with an all-purpose kitchen cleaner. If your countertop is tile, use vinegar or bleach water to clean the area to keep bacteria from growing in the grout of your tiles. Let the countertop dry completely
Place the tube of clear or colored silicone caulk in the caulk gun. Cut off the tip of the caulk at an angle using a knife or a pair of scissors. You need the hole at the tip to be large enough to let caulk through but not large enough that it gushes out. If you're unsure where to cut, start closer to the tip to err on the side of caution.
Start at one corner of your countertop. Place a bead of caulk along the edge where the counter meets the wall. Use a rag to wipe away any excess.
Let the caulk dry completely overnight. If you applied too much caulk and didn't wipe it away, cut away any excess caulk once the caulk has hardened completely.
Things You Will Need
- Putty knife or scraper
- Utility knife
