Bump. I've just skimmed a wall in my dining room, my first ever attempt at plastering.
Like many others I watched a lot of youtube videos and read a lot of the diyplastering.co.uk website, then got down to screwfix and bought trowel, bucket trowel, a fairly wide paint brush for the corners, a few large buckets, a drill whisk, a hawk, and a big bag of thistle multi finish from B&Q.
It's currently going off after two coats and a few trowel ups / polishes, and looking pretty darn good if I say so myself.
One thing that strikes me is that after the initial investment in gear (£100 or so for reasonable stuff), plastering is cheap. It's also incredibly satisfying to stand back and look at a wall you've plastered.
A few tips I'd pick out in particular:
- Concentrate on plaster consistency, otherwise you'll either drop it off your hawk if too thin or find it harder to apply if too thick.
- Concentrate on trowel angle and pressure. You need very firm pressure and the leading edge of the trowel should only be a cm or so off the wall on the return stroke.
- Break in your trowel if it's new. I used 1200 grit wet and dry paper for a good ten minutes on each edge.
- Do not start plastering until you've prepped and bonded the surface. You'll regret it and it'll waste time in the long run.
- Have a large bucket of water on stand by for leaving your tools in while you trowel off. This will stop the plaster going off on your hawk and bucket trowel etc. while you work on that perfect finish.
- For internal corners, use a damp paintbrush to move the plaster into the corners and even up the finish.
- Use one of those little squeezy sprayers to apply moisture when polishing.
Doing a fairly small wall has really given me the confidence to try more walls and maybe even a ceiling
