While there are many reasons to use nails in the walls of your home, a nail hole can be an unsightly problem. In addition to being unattractive, nail holes can make your walls prone to damage, both by weakening them and by slowly decaying. They can even cause problems with insulation. Fortunately, it is possible to seal a nail hole shut and solve all of these problems.

To close up a nail hole, you only need caulk, a few common household items, and the willingness to use them. Using caulk is a straightforward task that any homeowner can accomplish in an afternoon.

Step 1 - Preparing the Area

It is important to apply caulk to a clean area. Because of this, you will need to wash the nail hole and the area around it. To begin, get a rag damp in soapy water. Use the rag to scrub the nail hold and the area around it. Dry the area thoroughly with a second clean rag.

Step 2 - Preparing the Caulk Gun

Before inserting your caulk tube into the gun, cut off the tip with scissors or a utility knife. Try to cut off about 1/8 of an inch, though you do not need to be completely accurate. Finally, put the caulk tube into your caulk gun.

Step 3 - Applying Caulk

Now you can fill your nail hole with caulk. Put the tip of your caulk tube that you cut open earlier into the nail hole, or snugly outside it if it does not fit. Next, pull the trigger slowly to squeeze out caulk into the hole. Squeeze the caulk slowly, and evenly as possible. Additionally, it is important to hold the caulk gun as steadily as possible. Keep adding more caulk to the nail hole until you can notice excess caulk coming out of it, then stop.

Step 4 - Finishing Up

Once you have filled the nail hole completely, and you are sure of this because excess caulk has built up, go and get your dry rag damp. Use it to wipe away the excess caulk until your caulked nail hole is flush with your wall. At this point, there is nothing left to do. You can simply wait for the caulk to dry. This should take roughly 24 hours, though you should check the instructions on your packaging to be sure.

If necessary, you may wish to paint over your caulked nail hole to hide it completely. This is a particularly good idea if you have multiple nail holes that you are caulking, but it may not be necessary if the nail hole is not directly visible. If you choose to paint over the nail hole, wait until the caulk is dry to do it. Select a paint color that matches the current paint on your wall, then use a small brush to touch up the small area that you have caulked.
