Before we look into the procedure on how to repair cracks let us first know about various materials and plaster supplies in Doncaster required for the same:

  • Trowel: It is a long brace bar on the top side in contrast with the shorter bar on a mason’s steel float.
  • Hawk: It is the classic mortarboard device
  • Darby: It is a two-handled smoothing tool to level large flat areas and it is held flat against the wall as it is moved along and it levels out raised spots.
  • Screeding Rod: A straight-edged wood or metal stick to level off rough plaster applications.
  • Water-brush: This is used for finish plaster coating along with water.

Let us now look at the step by step procedure on how to repair cracks in plaster by solid plastering in Doncaster:

Preparation:

  • With a putty knife, chip out any loose or crumbling plaster from the edges of the hole or the crack until only the solid plaster remains.
  • Also, sand around the crack to roughen up the paintwork and dust the surface with a rag and cover up the surface with some jointing tape.

Applying the first layer:

  • Mix enough patching plaster to fill the hole almost completely. Moisten the back and edges of the hole with a sponge.
  • Beginning at the undercut surfaces at the edges of the hole, apply the patching plaster about some inches below the surface of the undamaged plaster.
  • While the patching plaster is still wet, score its surface with the tip of the taping knife.

Applying the second layer:

  • Mix a fresh batch of patching plaster. Dampen the scored layer of patching plaster and 2-3 layers of undamaged surface and around the hole or crack.
  • Use a taping knife, preferably wider than the hole, fill the hole with plaster to the level of the undamaged area and spread the plaster onto the surrounding surface for an inch or so.
  • Smooth this layer by drawing the knife blade evenly over the patched area and let the plaster set.

Completing the patch:

  • Cover the filled hole with a smooth layer of wallboard joint cement or vinyl spackling compound, using a taping wife.
  • Continue spreading the cement or spackling to an inch or so beyond the edges of the patching plaster. Let the patch area dry. When completely dry it would feel dry and it would have lost its clammy feel of wet plaster.
  • Sand the dry area smooth with a sanding block and soften the edges of the compound into the surrounding surface.
