How to fill holes left when a door strike was moved

Step 1: Prepare the area

Under this step, you should remove all the door locks, strikes, and other hardware from the latch hole. As advised by On the House, to fill a woodwork hole left by a mortise lock, it is ideal to use a sander to smoothen out rough edges in the mortise spaces.

Step 2: Dust the area clean

Since you will be applying paint and then a filler, it is advisable that you use a brush or any other cleaning aid to dust or clean wood shavings in the mortise area. This is a recommended practice by Home guides.

Step 3: Mix the Epoxy according to the direction

Following directions when mixing the epoxy is necessary if you want to achieve a mixture that is both soft yet able to harden and dry when applied to the old door latch hole. Therefore, the solvent and the resins must be proportionate as directed on the epoxy package. Most packages always come with instructions. However, where the epoxy you bought does not have instructions, kindly mix as reasonably and carefully as possible.

The mixing can be done on a piece of wood or any plastic that could serve the purpose.

Step 4: Apply the mixture in the latch hole

The consistency of the epoxy should be putty-like if you have followed instructions or done the mixture as required. And with a plastic scraper, apply a little mixture of the epoxy first to the side and bottom of the mortise area to fill in the strike plate hole. Then, scoop more to apply to the cavity, and take care to do this last. It is advisable to note that epoxy does not have the tendency to shrink if you have mixed it well. Therefore, do not attempt to overfill the mortise area with too much epoxy.

Step 5: Use a sander

The epoxy should be dry in no time, and afterward, you should sand off the area to get a flat surface. Where desired, you can apply the painting of your choice when your old door latch hole has been filled and is ready to use again for a new door strike.
