Scrim |
When Plasterboard has been used to board a wall there will always be gaps between the sheets, these gaps are weak points and when the plasterboard is plastered, these joints can often crack. To overcome this problem joints are taped with scrim which is a sticky fibrous tape, the tape itself is not really that sticky and only just sticks to the plasterboard. Once a coat of plaster has been applied though it will be impossible to remove.
 |
Smooth the tape into the joints ensuring that it covers both sides of the joint as equally as possible. Then cut it to the correct length using a sharp knife. |
 |
Here you can see that joints in both directions have been taped with scrim ready for plastering. |
 |
Internal corners also need taping to prevent cracking, again ensure that the scrim covers both sides of the joint equally. |
In this instance these boards are to be skimmed with finishing plaster, instructions on how to tape joints by using a jointing compound, will be covered at a later date.
