This is a very important part of the trade, it is not just about cutting out the damaged piece of Gyprock or other types of ceilings. Here is an example of a damaged piece of Gyprock to be replaced and the process followed:

Everything has a system, cover the floor with drop sheets, ascertain what section must be cut out, it is not good enough just to look at it and hazard a guess – you need to put a spirit level on it to see exactly how far the damage goes and ensure the job is done right the first time.

Once this is done you can begin to mark out on the ceiling or wherever needs to be cut.  Before and while you are cutting, it is crucial that you check for electrical wires, so every 200mm cut and stop and check that no electrical wires are there!

The damaged piece of Gyprock is now cut out, now 9 times out of 10, new trimmers (timber) are necessary to screw the new piece of Gyprock to. You need the new timber because you cut out a piece of Gyprock that was not originally fixed that way. The maximum span in most cases in timber or metal (Furring Chanel) is 600mm centres. The new piece of Gyprock is now screwed to the timber and it’s time for setting the joints.  Firstly, we Bond Crete the old painted surface.

Why do we do this?
We do this because this method helps the plaster to bond to the paint, it is not necessary to do this to new Gyprock. The first coat plaster goes on to the joint, we bed the tape into the joints. We allow this to dry, then the second coat goes on, the second coat should be about 500-600mm wide. This width is necessary to make sure the joint does not peak. The third and final coat goes on.  This is 600-800mm wide.

Once this dries it can be sanded and ready for painting.  This is a typical scenario for what is called a Butt-Joint
