How To Panel A Wall - DIY Guide

If you're looking for an easy way to add a bit of style and sophistication to your home, installing MDF panel moulding is a great option. This type of wall panelling is an affordable and relatively simple DIY project, and it can add a touch of elegance to any room. With just a few basic tools and a little time, you can achieve a professional-looking result that will impress your family and friends

Tools & Supplies

• MDF panel moulding
• Adhesive / hammer and nails
• Level
• Tape measure
• Pencil
• Saw
• Paint (optional)
• Sandpaper (optional)
• Spackle / joint compound (optional)
• Stud finder (Optional)

Installing MDF Wall Panels

1. Prepare the Wall

• Thoroughly inspect the wall and identify any holes, cracks or uneven areas. Running your hand along the wall can help identify hidden faults.
• Fill any holes, cracks or uneven areas in the wall with spackle or joint compound. Once dry, sand it smooth so you have an even foundation for your panels.
• Optional: Check for wall stud locations using a stud finder. Mark the centres of the studs with pencil lines.
• If the wall is highly uneven, you can install a backing board.

2. Plan the Layout

• Measure the height and width of the wall area to determine the panelling coverage needed.
• Decide on the desired panel spacing and layout pattern - Shaker, Warwick, Oxford etc.
• Calculate the number of full panels needed and cut the MDF moulding to the sizes required to complete the pattern.

3. Cut the Panels

• Use a table saw or mitre saw to cut the panels to the required sizes per the layout. A carbide blade is recommended for smooth cuts in MDF.
• Always wear eye protection and an N95 mask when cutting MDF to minimise dust exposure. Use a shop vac for dust extraction.
• Cut panels with factory edges outward to ensure the finished side is exposed.

4. Fit Panelling

• Measure and mark with a pencil where the panels will be installed.
• Apply 1/4" beads of adhesive every 12" across the back of each panel.
• Press firmly against the wall markings and use nails spaced 12"-16" apart for extra support.
• Repeat for all of the panels in your layout.

5. Fill Gaps

• Inspect for any gaps larger than 1/16" between panels or around edges.
• Fill these spots with painters caulk or wood filler. Tool it smooth and allow to cure fully.

6. Sanding (Optional)

• Sand the entire surface to smooth scratches or roughness, starting with 120 grit paper.
• Finish sanding with 220 grit to achieve a uniform smoothness. Be careful not to damage details.

7. Prime and Paint (Optional)

• Wipe the surface with tack cloth to remove sanding dust.
• Apply 1-2 coats of quality primer, lightly sanding between coats.
• Finish with 2 coats of latex wall paint in the desired colour.
  

Common Mistakes and How to Avoid Them

Installing wall panels is relatively straightforward but it's easy to make some mistakes if you're not careful. Here are some common errors and tips to prevent them:

• Not predrilling holes - Drilling pilot holes before inserting screws prevents cracking or splitting of the MDF. Always predrill.
• Uneven spacing - Use spacers and measure carefully to keep panel spacing consistent. Irregular gaps will be noticeable.
• Forgetting the adhesive - Don't rely solely on screws. Construction adhesive creates a stronger bond. Apply 1/4" beads to panel backs.
• Rushing the drying - Adhesives, caulk, filler need sufficient curing time. Following drying times prevents failures or bond issues later.
• Improper cutting - Use a sharp carbide blade and steady hand to avoid uneven or jagged panel edges. Measure twice and cut once.
• Scrimping on safety gear - Don't skip the safety glasses, gloves, or mask - MDF dust and sharp edges are hazards. Protect yourself.
• Ignoring the layout plan - It's tempting to eyeball panel placement but carefully following your planned layout ensures a professional finish.
• Sanding too aggressively - Use proper grits and light pressure to avoid rounding over edges or damaging carved details.
• Applying paint too thickly - Thin coats of primer and paint result in a smooth professional finish without brush marks or drips.

Safety Tips

Installing wall panels requires cutting, drilling, and working at heights. Follow these safety tips to avoid injuries:

• Use protective gear like safety goggles, gloves, and an N95 dust mask when cutting panels. MDF dust can irritate eyes and lungs.
• Use clamps to properly secure the panel you are cutting. This prevents movement and binding of the saw blade.
• Ensure adequate ventilation when working with adhesives or paints. Work in a well-ventilated area.
• When using power tools like a mitre saw or jigsaw, avoid loose clothing and tie back long hair. Follow all manufacturer safety guidelines.
• Have someone assist you when carrying large panels to avoid injury and damaging the materials.
• Use a sturdy ladder or steps to reach higher areas. Move slowly and maintain three points of contact.
• Locate and avoid wires, pipes, and other hazards behind the wall before cutting or drilling.
• Extract sawdust efficiently using a shop vac when cutting panels.
