How To Repair Holes In Walls Before Painting

How To Repair Holes In Walls Before Painting

Repairing holes in walls is essential when decorating to ensure a smooth finish. Follow this guide to wall repair to make sure your DIY gets a professional look.

Step 1: You will need

  • A putty knife and a tub of joint compound, aka spackling
  • A role of mesh joint tape
  • Several sheets of fine grade sand paper
  • A small tin of primer and a paint brush

Step 2: Repair smaller holes

Small holes like those left by old picture hanging nails can be easily and quickly fixed. Firstly remove any high spots, loose paint or rough edges with sandpaper.

Step 3: Make the repair

Add a small amount of joint compound to the tip of the putty knife. Apply pressure to the putty knife forcing the compound into the holes. Now allow the compound to dry.

Step 4: Sanding

Wrap a sheet of fine grade sandpaper around a sanding block, or any handy flat edge. This will ensure a smooth, even finish. Gently smooth the repair, removing any rough, high spots.

Step 5: Repair larger holes.

Remove any debris from within the hole and sand down any high spots and rough edges.

Step 6: Cover the hole

Cut two lengths of mesh joint tape, two inches longer than the hole is wide – this will give an overhang of an inch on either side. Place the first piece over the hole and press onto the wall, then form an ‘x' with the second.

Step 7: Apply the compound

As with smaller repairs add compound to the putty knife and begin to cover the mesh. Do not overfill the hole as the compound will begin to sag – wait for it to dry and apply another layer. Repeat until the hole is covered.

Step 8: Sand the larger hole

Using the flat block again, feather the repair and avoid spending too much time in one area as you will create an indentation or expose the Joint Tape. If this happens then you will need to fill with more compound and repeat the process, After a short while of sanding the repair will blend into the surrounding wall.

Step 9: Remove the Dust

You are almost ready to paint but first wipe the repaired area with a damp sponge to remove any dust that could stop the paint from sticking.

Step 10: Apply primer to repaired areas

Spot-prime the repaired areas. Primer not only helps blend the repair into the wall, but is essential in creating a bond between the nonporous surfaces of the compound and the new layer of paint. Apply liberally with a brush covering all the repaired areas of compound.
