How to Build a Frame For a Mirror

If you want to build a frame for a mirror, you can find a number of tutorials that show you how. However, there are a few things you should keep in mind. Among them are how to join mitred corners and how to conceal the nail holes.


If you have a wooden mirror frame you’d like to give a fresh new look, stain it. Alternatively, you can paint it. Whatever method you choose, make sure that you do it correctly.

First, you’ll need to remove the old mirror from its frame. The best way to do this is to use a chemical solvent. You’ll have to wear protective glasses.

Next, you’ll need to prepare the frame for painting. Painter’s tape is a good place to start. This will help you protect the surface of the glass. It also helps the paint stay in place.

If you’re unable to find painter’s tape, you can cover the glass with newspaper. You can then use a spray paint to paint the frame. Make sure that you get a smooth, even coat of paint.

Creating a dado

Creating a dado frame for a mirror is a great way to add a little bling to your bathroom. Not only is it a good way to create the illusion of space, but it can be made to match your style.

You’ll need four pieces of wood. They should be the same thickness, flat and square. Make sure they are the right length, as well. Measure the interior of the mirror to get the correct measurements for the frame.

Cut the wood to the length of the mirror using a table saw. If the frame is made from hardwood, you’ll need to add a rabbet to the back to hold it up. This is done after the frame is assembled.

You’ll need a miter saw for the 45 degree angle on the corners. A table saw is a better choice, as it’s easier to use.

Drilling pocket holes

Drilling pocket holes to build a frame for a mirror can be a great way to make a sturdy, easy to assemble frame. Using a pocket hole jig makes it easier to drill accurate holes.

In addition to a pocket hole jig, clamps are also useful to hold the wood pieces while drilling. To make the process go quicker, mark the sides of the pocket holes. This will prevent the holes from being drilled in the wrong spot.

For the mirror to hang, a rabbet must be cut around the inside of the frame. The rabbet should be at least 1/4″ deep. You can do this by using a wood router or a table saw.

Pocket holes are the ideal method for joining two pieces of wood to form a flat surface. They are strong and fast. Once the two pieces are drilled, glue is added to the joints.

Joining outer mitred corners

Joining outer mitered corners to build a frame for a mirror is an effective way to create a strong, attractive and functional framework. However, it requires accuracy and precision. With some preparation and proper tools, you can have a great frame with little effort.

Before you begin, you’ll need to measure and mark the mirror’s dimensions. This includes its width and length. You’ll also need to record its depth. To keep the edges of the mirror in alignment with the edge of the frame, you can use a carpenter’s square or a tape measure.

Next, you’ll need to make sure your battens are the same size. If they aren’t, they won’t be able to be joined properly. Likewise, the thickness of your battens needs to be the same.

Concealing the presence of the nails

Having a plethora of nails at your disposal can be an exercise in unpredictability if you don’t plan your project ahead of time. One good way to avoid this type of situation is to make sure the frame is a glued piece. The best way to do this is to use a small amount of adhesive in the corners. This will prevent the frame from bending resulting in a perfect fit. Once you’ve done that, you can start assembling the frame. For some framed mirrors, the process will last several hours. After that, you can start on your next project. If you’re not keen on a sanding session, there are plenty of premade stain and varnish kits to choose from. Alternatively, you could make do with a small bottle of spray on gloss.
