Applying Caulk

First, test your bead size on a paper towel or piece of newspaper to ensure the correct size. Pull the caulk gun along the joint. Pushing the gun can result in an uneven application.

Hold your tube at a 45-degree angle in relation to the area being filled. Apply a steady pressure to the trigger at all times. When you need to stop, simply release the trigger and pull back the rod.

Use a caulk finishing tool to go over your bead. This will smooth it and push the caulk in between the substrates. Do this before the caulk dries. Make sure you also remove the tape before the caulk has dried. The best way to remove this is by pulling it away at a 45-degree angle.
