How To Use Internal Filler Correctly?

Preparation is key when decorating if you do not prepare before you paint then your not going to get that perfect paint job.

Make sure your walls and ceilings are in good shape before painting because any dents, marks or scuffs will stick out when you have finished!

  1. Use a large scraper x2
  2. Be sure your scraper blade is clean/straight
  3. Apply the filler with one motion
  4. Complete all ceilings and walls
  5. When dry check your filler
  6. Use sandpaper or a sander
  7. Gently rub the filler until flush with the wall

If you have done a lot of filling then a sander or a large sanding pad attached to a broom handle will suit. Be sure to correctly sand the filler flush, use your fingers to confirm you have sanded enough and you cannot feel the edges of the filler.

If you do not sand your filler correctly then it’s going to stick out. Sand the filler and the wall around. Use 150 grit sandpaper for both ceiling and walls.

This will blend the filler and match it to the walls and ceilings in your property.
