Work from the inside out. Seal the inside seams and joints before the external ones so you don’t brush up against any wet caulk and have to reapply the sealant.
After you’ve applied the sealant, “tool” or smooth the bead of sealant with a caulk finishing tool dipped in water.
To ensure strong adhesion, make sure the area to be sealed is free of all old caulk, clean and dry. As a final step before applying new sealant wipe the seam with rubbing alcohol to remove residue.
Hold the caulk gun at a 45º angle to the surface and gently squeeze the trigger with steady pressure to apply an even and consistent bead of sealant to the seam. Move the caulk gun slowly and steadily, filling the joint with sealant.
For areas where it may be hard to navigate a caulk gun and cartridge, try using a squeeze tube. Squeeze tubes don't require a caulk gun and fit easily in the palm of your hand so you can get into tight spaces and corners. It's also great for smaller projects.
Prior to sealing, apply painter’s masking tape above and below the joint you’ll be sealing. Once you’ve finished, make sure to remove the tape while the caulk is still wet.
The “secret” to straight edges: Prior to sealing, apply painter’s masking tape above and below the joint you’ll be sealing. Once you’ve finished, make sure to remove the tape while the caulk is still wet.
Cut the nozzle at a 45º angle and load into caulk gun. Hold the caulk gun at a 45º angle to the surface and gently squeeze the trigger with steady pressure to apply an even and consistent bead of sealant to the seam. Move the caulk gun slowly and steadily, filling the joint with sealant.
