This type of plastering is mainly used in newly built houses and for refurbishments i.e. loft or kitchen extensions. It involves filling and smoothing only the joins and edges of the plasterboard and nail holes rather than skimming the entire area.
New plasterboard comes in two different thicknesses i.e. 9.5mm and 12.5mm.
Tapered Edge plasterboard (TE) is used for Ames Taping because the board is slightly indented on the long edges. When two lengths of this board are joined together at the tapered edge, it creates a low narrow channel which is the main area to be filled and then sanded down.
Prior to applying any material all the joins and edges must have scrim tape applied as this prevents cracks appearing later.
The non – tapered edges of the plasterboard have no channel to fill and will require a slightly wider spread of material so that a bevel is not created.
This process normally takes two to three coats, sanding down lightly after each coat is dry to level with the plasterboard.
Plasterboard Repair (Dry-Wall)
Damaged plasterboard can be repaired easily by cutting out a new piece of board leaving the top surface paper of the new board to overlap the area cut out (Chicago patch). Fillers are used to smooth over the newly repaired section which is then sanded down to the level required. This method is ideal for small holes.
If the area to be fixed is larger than say 12” x 12” then it is better to fix larger sections of plasterboard by screwing into the wooden joists.
