Hiding screw heads in various areas of the home gives the walls, moldings or other joined pieces a finished look. Using screws to hold drywall to wall studs results in a secure connection making the walls stable. Adding moldings to the walls with screws creates a tight bond, but leaves behind unsightly screw heads. There are several techniques that will hide screw heads; just choose the easiest method based on your personal preferences.
Apply joint compound with a flexible putty knife to the sunken screw head, pressing it in deeply and firmly.
Allow the joint compound to dry fully, generally one to two hours. Use fine-grit sandpaper to sand the joint compound flush with the existing wall.
Apply self-sticking fiberglass tape over the joint compound.
Apply another thin layer of joint compound over the fiberglass tape, feathering the edges. Feathering means to make the layer of joint compound thinner and thinner towards the edges. Allow the joint compound to dry fully, one to two hours.
Use fine-grit sandpaper to smooth and level the joint compound with the exiting wall.
Apply wood putty over the screw head, pressing it in as far as possible.
Allow the wood putty to dry completely, typically one to two hours.
Use fine-grit sand paper to smooth the wood putty making it flush with the existing woodwork.
Homemade Wood Putty
Save saw dust from your project and mix it with wood glue to form a thick paste consistency.
Apply homemade wood putty over the sunken screw head with a flexible putty knife.
Allow the mixture to dry thoroughly, usually one to two hours.
Sand the homemade wood putty surface with fine-grit sandpaper making it flush with the existing surface.
Measure the head of the screw and buy a wooden dowel the same size as the screw head.
Use a utility knife or fine-cut saw to cut a thin slice from the end of the dowel.
Paint the screw head with wood glue.
Press the piece of dowel in on top of the screw head, fill in the seam around the dowel with wood glue and allow the glue to dry, usually one to two hours.
Sand the surface with fine-grit sand paper to smooth it, then prime and paint.
Load a caulking gun with all-purpose paintable caulk. Slide the plunger on the caulking gun back until it clicks and locks in place. Put the pointed end of the caulking tube through the circular end of the gun and push the body of the tube down so it lays on the caulking gun housing. Release the slide plunger gently until it lays firmly against the bottom flat end of the caulking tube and cut off the pointed end of the tube.
Squeeze a small bead of caulk over the screw head.
Use a rubber-gloved finger to smooth the caulk surface and allow the caulk to dry, usually within an hour.
Apply primer and paint to hide the screw head.
