Tools Used:


Arrange house numbers on uncut plywood to determine the size of your sign. I arranged the letters to have 1 – 1-1/4 inches all around the outside of the numbers. The size will vary according to what numbers you use, but my sign was 17-1/2 x 7-1/4″.

Once you determine the size, use a table saw to cut the plywood to size.


Paint the sanded plywood white and the uncut trim piece black. Use a roller to create a smooth finish without brush strokes, using fine grain sandpaper in between coats of paint.


Once the paint is dry on the sanded plywood, use the house number guides to determine where holes need to be drilled. Tape the guides in place with blue tape to prevent them from moving.

Use the Nail Set and hammer to mark where each hole will be drilled (a Punch would be preferred but we couldn’t find ours). This will help the drill bit stay right where you want it without sliding.


Use a miter saw to cut the trim at 45 degrees. Start with one edge, making sure the trim pieces fit together around the outside of the plywood without gaps. It is super helpful to have another pair of hands to help hold the unattached pieces of the frame to ensure they fit together.

Once the trim is cut to size, use paint sticks (2 high) to raise the sanded plywood so that it will be situated in the middle of the frame. Start with one trim piece at the time. Apply wood glue to the edge of the sanded plywood that you will be affixing the trim to.

Use a finish nailer to nail it in place. Work around the edge of the sign, affixing using the same method.


Fill holes, allow to dry, sand then paint. Touch up and dings or nicks and around the edges.


Then, using your Mikita Impact Driver, drill holes for the screws where you have marked using the Punch. This is a great tool that packs a lot of punch but is still lightweight.


Then seal with with a non-yellowing, polycrylic or clear enamel. You could skip sealing the sign, but since our sign will be on the front of the house without any shelter, we wanted to make sure it would not warp or rot quickly. When sealing, be sure to seal the back also!

True story here – I used an old polycyclic and it was super yellow. UUUUUUUGGGGHHHH. So I had to sand it, repaint and reseal. So frustrating.


Once dry, attach numbers using screws and Husky screwdriver. Okay, a few thoughts… I bought these specific house numbers because I thought they were the prettiest!! And I stand by that. But what I didn’t realize was that were were literally the only number that use headless screws and anchors to affix them. Not a big deal, except the anchors and screws were way to long to work with our sanded plywood. It was a bit of an ordeal.  In the end, we bought pan-head, machine screws.

Affix a picture hanging wire on the back and hang that mother up!!
