Most Common Caulking Mistakes

Preparation is essential

When you open a tube of caulk, you make one of the most common mistakes. You won’t be able to make it last without preparation of your surface. You must take away the old caulk, flakes of paint, and crumbling grout before laying a new bead. Make sure any surface damage is repaired before you apply the new bead.

The right cut

Whenever the caulk is opened, you can customize the opening according to your specific needs with the tapered tip. The tendency for many people is to cut the caulk tip and seal the crack without considering the size of the crack. Consequently, the surface becomes sticky or has too much material on it. When cutting the tip, make the opening a little narrower than the tip by applying pressure and speed.

Gaps need to be filled

There is another pitfall when it comes to width – filling large gaps with caulk. Foam rope is required for openings that are more than half an inch deep or more than a quarter-inch wide. It is costly and affects the performance of the product to fill a crack with caulk. In addition to optimizing thickness, backing material provides the best cosmetic finish.

Be patient

Many people rush right into work, putting material to use immediately. Creating a bead of caulk that looks good and performs well takes a certain amount of skill.

You can practice on a grocery bag instead to get a feel for how much pressure to apply and how the bead emerges. The key is consistency. Similarly, you can jump into a long bead without stopping.

There may not be enough space for the caulk gun near the end. Consequently, your nicely crafted beads become a mess. Caulk first the last 6 inches, or work from edge to edge. Try to maintain consistent speed, angle, and pressure.

The Final Step

Last but not least, the finishing process is a common pitfall. There is one more critical step to complete: For most caulking jobs, you only need some water, some paper towels, and your fingertip.

When you smooth the bead with your fingertip (or metal spoon or ice cube for exterior caulk), you achieve two things: The caulk adheres firmly to both surfaces, and it appears tidy and clean.
