Use heavy duty protective sheets to protect the floor, and make sure any furniture is covered with dust sheets
Unless you are working with new plasterboard, you will need to remove any loose plaster, paper, dust and grease from the area you wish to plaster. Then treat the plaster with a primer of water and PVA glue following the manufacturers guidelines.
Step 1- Apply a plaster tape to cover any joints between plasterboard sheets, use a snap off knife to trip the tape.
Step 2- to prepare the plaster mix, always add the water first to stop the mixture from becoming lumpy, and start by half filling a bucket with clean tap water. Slowly add the plaster powder, make the plaster in small quantities instead of one large quantity at the start.
Step 3- using a bucket trowel wipe any dry plaster around the edge of the plaster, and keep mixing (either manually or using a power stirrer, make sure to clean the power stirrer before the plaster sets), repeat as needed
Step 4- if plastering a large area, use a spot board to pour your plaster on, it should be thick enough that it doesn’t run. Using a plastering trowel, cut away a section of the mixed plaster and transfer to the plastering hawk. If working with plasterboards, we recommend adding a thin coat over the joints first.
Step 5- Push a section of plaster up and onto the wall surface using the plastering trowel, spread from left to right. Press firmly, and distribute the plaster evenly
Step 6- If plastering around sockets, disconnect the electricity supply first and cover the socket
Step 7- work quickly and build up rhythm to cover the surface before the plaster begins to set, go back over the whole surface with a thin coat and smooth to an even thickness
Step 8- follow the manufacturer’s instructions, leave the plaster to dry until the surface is still slightly damp to touch
Step 9- Go over the whole surface with a clean trowel blade, use a spray bottle to dampen the surface as you go if needed
Step 10- for the best smooth level finish hold the blade so only one edge is on the plaster. Use a small damp brush to smooth edges and corners.
Step 11- following manufacturer’s instructions, allow to dry and repeat this process.
