How to Build a Wood Frame Mirror How to Build a Wood Frame Mirror
With any size and type of mirror, building one with a wood frame is an economically practical way to add the illusion of space to a room. Wood can be chosen, painted, and customized to match with any decor style, and this DIY project only takes some basic building skills and attention to detail.
Step 1 - Measure the Mirror
Use the dimensions of the mirror to determine the exact measurements of its wood frame. The circumference of the mirror's edge should match up with the inner edge of the wood frame. You will create a dado, or groove, to fit the mirror along this edge of the wood.
Step 2 - Cut Frame Dado
Use the table saw to carefully cut the dado groove in the wood; this should measure about 3/8 inch deep by 1/2 inch wide. Be careful not to cut too widely, otherwise the mirror will fit into the frame too loosely. Measure from the point that is longest within the dado and leave approximately 1/8 inch allowance for fitting the wood frame securely. Also cut out each of your wood frame pieces. Remember to measure twice and cut once.
Step 3 - Assemble Wood Frame
Glue your wood frame pieces together and secure them with small finish nails. Use a small amount of wood filler to seal any gaps, and then sand your new wood frame with a fine grit sandpaper to remove any potential splinters. Brush off any wood dust, and then apply a wood stain of your choice. Let all of the glue and wood stain dry for about 24 hours.
Step 4 - Add the Mirror
Turn your finished frame to the face side and apply a line line of the silicone caulk to the entire edge of the dado groove. This should be about 1/4 inch away from the very inner edge. You may want to wear work gloves to protect your hands from any sharp mirror edges. Carefully lay the mirror in place, and then squeeze another line of silicone along the edge between the mirror and the finished wood frame. Follow the silicone caulk's recommended instructions as far as drying and curing time.
Step 5 - Add Wire and Hooks
Measure 4 inches down from the top of the mirror frame on the back side. This is where you will screw in the picture frame hooks, making sure they are even on each side. Using a level or straightedge can help with this if needed. Attach each end of the picture wire through each hook and wind them securely in place. Check that the angle of each wire rests about 2 to 3 inches below the center top of the wood frame. Use a strong nail to attach your new mirror to the wall, and check that it hangs straight down.
