Framing Bathroom Mirrors: A Bedroom's Quick Upgrade

Framing a bathroom mirror is a simple and cost-effective way to update the look of your bathroom. It can be done in a variety of ways, from using stick-on frames to creating a custom frame with wood and glue. The process typically involves measuring the mirror, cutting the frame to size, joining the frame pieces, and then attaching the frame to the mirror. This can be done by gluing the frame directly to the mirror or using adhesive strips. Some tutorials also recommend filling in gaps with putty or wood filler and painting the frame to match the style of the bathroom. Overall, framing a bathroom mirror is a great DIY project that can be completed in a short amount of time and on a budget.

Measure and cut your lumber

The first step in framing your bathroom mirror is to measure the width and height of your mirror using a tape measure. It is important to be as precise as possible when taking these measurements, as they will determine the size of your frame.

Once you have the measurements, decide on the type of lumber you will use. You can use primed MDF boards, which are easy to work with and affordable. Alternatively, you can use 1x4x8 white wood boards or 1x4 lumber (actual dimensions 1/2-in. x 3-1/2-in.).

After selecting your lumber, it's time to cut the pieces to size. If you're using MDF, mark the measurements directly on the boards and use a miter saw to make your cuts. For a simpler approach, you can forego miter cuts and only make straight cuts, which will make the project faster and easier.

If you're using 1x4 lumber, cut four pieces aiming for a frame that protrudes 1 inch beyond the mirror's edges on all sides. For a 20-inch by 30-inch mirror, cut two 22-inch pieces and two 25-inch pieces. The 22-inch pieces will go on the top and bottom, and the 25-inch pieces will fit between them. Ensure that your cuts are exactly 90 degrees to the board's edge for a precise fit.

If you're using white wood boards, you can have them cut to size at the store, or you can cut them yourself. For this project, you'll need horizontal pieces that match the width of your mirror, plus an additional half-inch. The vertical pieces should match the height of your mirror, minus twice the width of your board (approximately 7 inches for 1x4 boards).

After cutting your lumber to size, lay the pieces on the mirror to ensure they fit together well and make any necessary adjustments.

Prepare your work area

Before you begin framing your bathroom mirror, it's important to prepare your work area to ensure a smooth and efficient process. Here are the steps you should follow:

• Gather all the required materials, including the mirror, frame pieces, adhesive, paint, paintbrushes, sandpaper, and any other necessary tools. Lay out the frame pieces and trim on a flat working surface to visualize the finished product and ensure you have everything you need.
• If you plan to paint your frame, add a latex paint extender to the paint to lengthen the drying time and minimize brush strokes. It is crucial to paint both the front and back sides of the frame, especially the edges that will extend over the mirror's edges, to achieve a smooth and consistent finish. Allow the paint to dry completely before proceeding to the next step.
• If you're using a miter saw or hand saw to cut your frame pieces, ensure that the cuts are precise and exactly 90 degrees to the board's edge. This will result in smooth and accurate cuts, creating a polished final product.
• Lay out your cut frame pieces on the mirror to check their fit. Ensure that the frame protrudes evenly beyond the mirror's edges on all sides, creating a symmetrical and aesthetically pleasing design. If adjustments are needed, re-cut the pieces to achieve the desired fit.
• If you choose to join the frame pieces before attaching them to the mirror, use a drill and pocket screw drilling jig to create holes for pocket screws. This step will help you achieve a tighter fit at the joints and simplify the gluing process.
• Join the frame members using a screwdriver and wood screws. Be sure to tighten the screws just enough to pull the parts together securely without overtightening, as this may strip the holes and reduce the grip of the screws.
• Sand the frame to smoothen its surfaces and create a seamless finish. Use a random orbital sander with a 120-grit disc for the initial sanding, followed by hand sanding with 120-grit and 220-grit paper. Remember to sand in the direction of the wood grain to avoid scratches and always work in a well-ventilated area when sanding.
• Vacuum the frame and surrounding area to remove any dust particles before proceeding to the finishing step. A clean work area will help you achieve a professional-looking result.

Paint the backs of the trim

Painting the backs of the trim is a crucial step in framing a bathroom mirror. This step ensures that the brown MDF is not visible in the mirror reflection, adding a professional and polished look to your project. Here is a detailed guide to help you achieve the best results:

Step 1: Prepare the Work Area and Materials

Lay out a drop cloth or newspapers to protect your work surface. Gather your materials, including paintbrushes, paint trays, and the paint colour of your choice. It is recommended to use a roller specifically designed for cabinets and trim to achieve a smooth and streak-free finish.

Step 2: Paint the Backsides of the Trim

Before you begin painting, add a latex paint extender to your chosen paint. This will lengthen the drying time and minimise brush strokes, resulting in a smoother finish. Start by painting the backside of the trim, focusing on the edges that will extend over the edges of the mirror. Allow the paint to dry completely, following the manufacturer's instructions. This step is crucial, as the back edges will be reflected in the mirror.

Step 3: Paint the Front Sides of the Trim

Once the backside is dry, repeat the process and paint the front sides and edges of the trim. Again, allow the paint to dry completely. For a smoother finish, consider lightly sanding the surfaces with an extra-fine sanding pad and wiping them clean with a tack cloth before proceeding to the next step.

Step 4: Final Touches

After the front sides are dry, you can add any final touches, such as a second coat of paint or a clear sealant to protect the paint. Remember to let each layer dry completely before handling or installing the trim.

By following these steps, you will achieve a professional-looking finish for your bathroom mirror frame, adding character and value to your space.

Sand the MDF board

Sanding the MDF board is an important step in creating a smooth and professional-looking finish for your mirror frame. Here is a step-by-step guide on how to sand the MDF board:

Choose the Right Sandpaper:

Select a fine-grit sandpaper, such as 120-grit or 220-grit, for the best results. Finer grit sandpaper will help create a smoother finish.

Prepare Your Work Area:

Before you begin sanding, ensure your work area is clean and well-ventilated. MDF boards can create a lot of dust during the sanding process, so it is important to protect your workspace and wear a respirator or mask to avoid inhaling the dust.

Lightly Sand the Board:

Using your chosen sandpaper, start sanding the MDF board lightly and evenly. Always sand in the direction of the wood grain to avoid scratches. Pay extra attention to the corners and edges, as these areas may require more sanding to smooth them out.

Sand Until Flush:

Continue sanding the board until all the frame members are flush with each other. Run your fingers over the joints to ensure you cannot detect any mismatch or uneven surfaces. This step is crucial for achieving a seamless finish.

Remove Dust:

Once you are satisfied with the smoothness of the board, use a tack cloth or a damp cloth to remove any dust or debris created during the sanding process. It is important to ensure the board is completely clean before proceeding to the next step.

Repeat as Needed:

Depending on the desired finish and the condition of your MDF board, you may need to repeat the sanding process with a finer grit sandpaper, such as 220-grit. This will help create an even smoother finish and remove any scratches created by the previous sanding step.

Prepare for Finishing:

After sanding, your MDF board is now ready for the finishing process. You can choose to paint, stain, or apply a clear finish to your frame. Remember to always follow the manufacturer's instructions and recommendations for the best results.

By following these steps, you will be able to achieve a beautifully sanded MDF board that is ready for the finishing touches of your DIY bathroom mirror frame project.

Glue the frame together
