Learning how to plaster wall and ceilings
- and how I plastered my bathroom and toilet! -
As can be seen from the web pages on www.gare.co.uk, I've been a keen DIYer for many years and I have even built a complete house extension from scratch. However, like most other DIYers I've always shied away from plastering complete walls and the thought of plastering a ceiling scared me to death!
However, I needed to redecorate a bathroom and a toilet that I had tiled way back in the 80s and I knew that as soon as take them off much of the plaster would come away with them leaving a real mess of all the walls.
I suppose I could have called in a local plasterer but I had been thinking for months that it might be a good idea to go on a plastering course and learn how to plaster and overcome my fears!
It was February 2013 and I started a Google search for a suitable plastering course. I soon found one at the local technical college, but my phone calls came to nothing as they messed me around somewhat. Then I came across Silver Trowel which was nearly in walking distance from my home! Wow! One of the courses they offered was for four days spread over two weekends. This sounded perfect for DIYer like myself. And they were running a course starting next weekend! So I paid by credit card and started wondering what the hell had I had let myself in for!
We dove in immediately with Chris, the trainer, explaining all the tools and how to use them. He then showed us how to skim plaster a wall by plastering one! When the 15 minute demo was over we were shown the little bay we were each assigned and told to get on with it! Talk about being thrown in the deep end!
The bay had a small window, a fairly large wall and - OMG a ceiling!
Yes you guessed it - we were asked to plaster the large wall first.
I'm sorry to let you down here but unlike my other websites, I do not plan to take you through all the steps we learned to produce perfect skim-plastered walls. Though I will say it is a very straightforward and achievable process if you are a practical individual.
The reason for this is that I really do recommend that you go on a course and practice. It's the only way to gain confidence.
However, I will say that roughly the process involved the following stages (a) two coats of diluted PVA adhesive to the bare walls (b) first skim using the techniques taught with Thistle Multi-finish plaster and let dry to the right stage (c) second skim and and let dry to the right stage (d) three 'wet coats' to get that polished glass finish.
A good book to read is the Plastering NVQ Level 2 Student Book.
A normal plastering trowel needs to be broken-in over many weeks by a plasterer. This means that the edges are worn down or 'feathered'. This is already done for you on a pre-broken in trowel and it REALLY helps you to create a good finish from the off. It's worth the extra cost.
This is the area where you mix the plaster using a tub and a plastering wheel
And, where it is drummed into you top keep the tools clean. One tiny piece of grit can destroy attempts to create a glass-like finish to the plaster skim.
I have to say that I think I got more plaster on me than on the ceiling at times while standing on the step-up.
However, slow I may be but the ceiling looked pretty good for a first attempt.
You have to do things fast or the plaster goes off - technique and speed are all!
Well, this is much of what you learn on the course and all you can do now is to practice, practice, practice to improve speed and finish.
All I can say is that after the four days of training I felt confident enough to plaster my bathroom.
Gulp! The next task was to strip the tiles from my bathroom walls and start the re-plastering exercise - when I had plucked up the courage to do so. This was entirely different to plastering a wall on the training course wall.
These holes would have to be completely filled in before I could even contemplate a plaster skim.
I did wonder whether it would have been quicker to strip of all the old plaster but I decided not to and in retrospect I believe I was right in this decision.
Many years ago I put plasterboard over the old plaster and lathe ceiling. As I never plaster skimmed it, it was always a bit of a mess I have to admit.
Now however, after skimming it it looked pretty good!
I did not rush this and only did one wall a day. I thought it better to take things slowly.
It did take five whole days to complete the bathroom but I wasn't in a rush.
The plaster is still drying in this picture.
Although I was hesitant about going on a plastering course, I'm really pleased that I did. Not only have I a very nice bathroom and toilet to show for it, but I can shock colleagues by saying that I went on one and plastered ceilings in my house. How's that for a bit of one-upmanship!
Why don't you give it a try?
