Preparing The Wall For Plaster
Before we start to apply the product, let’s look at the information on the bag. On the bag, you will find a use-by date, make sure the plaster is within its use-by date. This information is printed on all bags of plaster.
Before applying the plaster, it is important to check that the background is suitable for the plaster by referring to a technical information sheet and that any background preparation has been completed. As part of the background preparation, angle beads should be fixed in position using plaster. Once applied and lined in, the angle beads should be left to set before the application of the plaster.
When mixing plaster, always add the powder to clean, cold water. Mixing should take place in a well-ventilated area, with the correct PPE being used by operatives. Keep adding powder to the water and mix the plaster to the required consistency.
Applying Plaster To The Wall
Using a trowel, apply the first coat of plaster to the background. Once the entire background has been covered, a second coat of plaster should be applied over the whole surface. Once the required thickness of plaster has been applied, the wall can be ruled off with a derby, serrated straight edge or a feather edge.
Any low or hollow spots that have been missed during the spraying process can be filled in once the wall is level. A spatula should be used to close and flatten the surface of the plaster. When the plaster begins to tighten and firm, it is ready to be sponged using a sponge float. The sponge float is rubbed over the surface of the plaster, using circular motions to bring the fat to the surface ready for a finishing trowel.
Once the sponging process is complete, the plaster should be left until stiffened, then a final trail using a spatula, trowel or speed skim should take place, to leave a flat seamless finish.
There you have it, a plastered wall finished in no time.
