Plaster Repair Tools

  • Ladder
  • Putty knife to scrape 
  • Trimming knife 
  • Safety glasses and a dust mask
  • Paint scraper with a wide blade to apply plaster compound

Plaster Repair Materials

  • Plaster joining tape
  • Plaster compound
  • Rag or cloth
  • Sanding block with sandpaper

Step 1: Preparing the cracked surface

The first step to repairing hairline cracks in plaster ceiling is to create more of a surface for the plaster compound to bond with. Simply scrape the crack with your putty knife to open it up. 

Step 2: Sand the surface

From here you will need to sand the surface. Again, this will ensure a better bond by ending any paintwork. 

Step 3: Dust and apply joining tape

Dust the surface thoroughly and apply joining tape to cover the crack. By dusting this will ensure the joining tape has good adhesion to the area. 

Step 4: Apply plaster compound

Once the joining tape has been applied you can now use your paint scraper to apply the plaster compound. Be sure to flatten it onto the wall with your paint scraper. 

Step 5: Dust, sand, and repeat

Once the plaster compound has completely dried you can sand the area until it’s smooth and dust away on completion. Now you will apply the plaster compound, extending the application a little wider than initially applied. 

Once dry again simply sand the area and dust off the area before painting.
