All walls in the home can develop cracks over time and not all cracks that appear require the attention of a plasterer. Most small cracks can happen due to the minute movements within the structure of the house over the changing sessions. For example the expansion and contraction of the joist in ceilings and floors.
Repairing a hairline crack
- Before you start any DIY job it’s always good to take a few minutes to get some protection down and clear your work area of any furniture. [Picture]
- Guest thing to do is to “V” out the length of the crack with a Stanley knife, to achieve this V-shape simply hold the knife on its side and scrape at a rough 45 degree angle. The aim of this step is to give the crack more depth for the filler to sit in. [Picture]
- Next step is to brush or blow out the dust and any bits from the grove. [Picture]
- Once the grove is free from dust and any debris, mix up the filler to a stiff paste consistency so that if you want to hold the filler upside down in the container if wouldn’t fall out.
- Now dampen down the area to be filled with water with a small brush or spray bottle as this will help the filler adhere in the crack. [Picture]
- Spread the filler into and along the damp groove. Once done, rule off and be careful to not leave the filler too proud of the surface of the wall.
- Once dry, gently sand down with a medium sandpaper then finishing with a fine grade sandpaper before decorating.
