Prep the surface
Proper surface preparation is key. Remove any old caulk from the seam or joint by cutting or scraping away. Clean the area with soap and water to remove dirt, dust, grease or debris, and rinse thoroughly. Make sure the area to be sealed is clean and dry to ensure strong adhesion.
Get a professional-looking finish
Want straight, professional finish lines? Apply painter’s tape to either side of the joint before applying the sealant. Smooth the bead of sealant with a caulk finishing tool dipped in water. Remove the tape before the sealant skins over- about 2-5 minutes. To remove, lift the edge up at a 45-degree angle and pull away from you.
Use backer rod
Preparations should be made for extra large gaps - use backer rod on any joint sizes that are deeper or wider than 1/2”.
