Plastering - How hard can it be.

I have no idea about this paint roller technique, but I did DIY a couple of small walls in the last house.

It wasn't that tricky to be honest, but the second wall was a lot better than the last - the first needed a bonding coat.

That's where it gets tricky, if you let the bottom coat dry out it's dam difficult to get it wet enough not to suck up all the water in the mix.
Skimmimg or board finish is altogether easier.

I would LOVE to see a link to the paint roller/squeegee video. I've never heard of such a thing.

I'm a DIY plasterer, but I did a week-long course beforehand to learn how to do it. I've now re-plastered about half my flat and agree with one of the earlier posters that I started out pretty rough but have gotten better and better. Now my finished walls and ceilings are as smooth as glass. It is physically quite demanding (especially ceilings as you're working overhead). However, with perseverance and speed you can get good quite quickly. |If you're just starting out I would practice on a single wall and re-plaster it several times until you get good (you're going to have a very thick wall though!). Oh, and plastering over plasterboard is much easier than applying plaster to an old wall. Plasterboard is cheap and can be quickly put up using plasterboard adhesive.

any chance of some before and afters

We will start with a couple of "before" shots.



The walls had been painted with an icky yellow paint sometime last century, and these two snaps fail to show how bad the plaster underneath really is. The only saving grace is the corners are solid (almost like concrete), so I have a reference edge to work to.

Going to make a start on it in the morning, assuming I don't get sidetracked.

IF I had wanted grungy bricks, I'd have hacked off all the plaster & render. But I don't !

Even if I paper, the underlying plaster would still need to be fixed. Haven't decided to paper the walls or paper them yet - Kinda fancy the idea of venetian plaster...

Distemper (lime paint)
You got to get rid of it

Doesn't have the appearance of distemper - The paint is quite solid, not powdery or water soluble. Another wall that had been painted was skimmed with a gypsum plaster a few years back. This one was primed with PVA, then plastered - Still good some twenty years on.

Update: First wall done, will post an after shot when I've done the other wall and everything has dried out,

And the after shot - Still damp in a few small spots. A lot smoother than the original, and it is good enough to paper over now. Don't need to go right to the floor as the skirting boards will hide the mess at the bottom.




If anyone else want to try applying plaster with a roller, a few tips..

Mix a fairly sloppy mix - I used approx 500ml of water to each kilo of Thistle Multifinish.

Use a good quality PVA diluted 1 to 3 before plastering - It slows the absorption of water which is a big help if going over thick/old plaster.

Roll on several coats of plaster, waiting for about ten minutes between each coat - I used three coats before troweling which gives me a thickness of around 1mm.

There are also plasters out there designed for roller application - Darned expensive.. http://www.kreidezeit.de/EnglischeVersion/ProdukteENG/MerkblaetterPDFeng/Brush-%20and%20Roll-on%20Plaster_EN.pdf
