Plastering is largely about timing. So to be able to complete 60m2 of skimming, like the plasterer did in this image, in just a few hours, takes a good knowledge of how to time your gauges and when to flatten in the wall.
One of the enjoyable things about plastering is that everyone has there own style and their own way of doing things and so whilst I cannot speak for everyone I can say how I would go about completing this task:
- Prepare the work area by loading all the materials needed for the wall, especially bags and water.
- sweep all dust and anything else away from the bottom of the wall
- Bead the column and fibre tape the joints (sounds obvious but I have seen some that will mix up and then start doing all these things whilst the plaster is setting in the bucket).
- Mix 3 bags of multi or board finish and immediately fill all the vertical joints and apply a thin coat to any horizontal joints and fill out the beads. This operation should only take a few minutes don’t spend a lot of time on it.
- Apply the remaining plaster and immediately flatten it in once to get the high points down. Ideally you don’t clean the bucket unless it took you too long to apply the first coat and it started drying in the bucket.
- Mix another 3 bags right away and apply to the remaining area. You should have just enough to first coat the entire wall.
- Then give the entire wall one quick flatten.
- Clean the beads an make sure there are no snots!high points particularly to the top and bottom of the wall.
- Mix about 2 bags and give a tight coat to the entire wall.
- If timed right about another 3 trowels and a polish should finish the job all in about 3-4 hours. Some plasterers might even have another knock on gauge as well especially if there is a labourer there to mix up.
So if your not making enough money and still mixing 2 bags and waiting until they are set and finished before mixing again you must get your head around proper timing because there is serious money to be made but only for serious spreads.
