How to skim plaster step-by-step
Now that you have prepared the space, let’s look at how to skim plaster. Remember that this can be a difficult skill to master and you will need to work at a good pace to avoid the plaster setting.
- Start by mixing the plaster powder with water as per the manufacturer’s instructions. Only mix together a small amount of plaster to begin with so you don’t run the risk of the plaster drying out. Top tip: To get a perfectly even mixture of plaster, hire a power stirrer.
- As soon as the plaster mixture is ready, pour it out onto the spot board.
- Make sure you quickly clean out your bucket, so the plaster doesn’t have time to set.
- Separate a small chunk of plaster and move this to your plastering hawk, ready to start.
- Transfer a small amount of plaster onto the wall and quickly begin spreading it evenly with your trowel. Keep up a good pace as you push down on the plaster while spreading it horizontally and vertically for a smooth finish.
- Then, allow the plaster to dry as per the manufacturer’s instructions before you start again, applying a second coat in a similar manner to the first.
- Dampen the plaster and use your trowel to smooth out the finished plaster.
- You can also use a damp paintbrush to finish the edges of your wall.
