Repairing surfaces


Repair products are used to fix damaged surfaces.

Repair products are used to fix damaged surfaces. They include fillers, like wood filler, putty, mortar and so forth. You should select the best filler for the job. Read manufacturer’s instructions for the filler and its uses.

Before fixing surfaces, clean and sand as described in sections “Cleaning Surfaces” and “Sanding Surfaces”. It is also recommended to seal wood surfaces before repairing. Use a primer, stain or paint you purchased. Note: The painting must be a product "paint and primer in one."

Learn how to:

Fixing previously painted masonry surfaces:


  • Appropriate filler
  • Scraper
  • Wide putty knife
  • Shop vacuum cleaner
  1. Scrape paint away from hole or crack with scraper or putty knife.
  2. Remove damaged brick and vacuum away residues.
  3. Sprinkle water on the edges of the hole so the filler will stick.
  4. Fill hole with filler using a trowel or wide putty knife.
  5. Let filler dry completely.
  6. Repeat as needed.
  7. Wait 2 to 3 completely dry days before painting brickwork. Brick moisture content should be less than 6%.

Fixing previously painted wood surfaces:


  • Appropriate filler
  • Putty knife
  • Sandpaper
  • Nail set and hammer
  • Shop vacuum cleaner
  • White, moist, lint-free rags
  1. Scrape away paint with putty knife.
  2. Remove rotten wood and any loose pieces of wood.
  3. Sink any extruding nail heads with the nail set.
  4. Sand surface with a medium-grade (80, 100 or 120) sandpaper and vacuum up dust.
  5. Fill holes with plastic wood.
  6. Let dry, sand with progressively finer grades sandpaper (150, 180 and 220) and vacuum up dust.
  7. Repeat as needed.
  8. Wipe with a white, moist, lint-free rag. The moist rag removes any dust left by the vacuum cleaner. Soak rag in clean lukewarm water and wring out thoroughly before wiping to avoid leaving behind any moisture that could cause wood to swell.
