Sander Down.

[Bob Dalek]

Just did. It looks more like a smooth artex then plaster. Is it any good?
What problems did you have?

No problems. It rolls on. That's it.

Or use lining paper - a bit pricey, but does the job.

Google for it - can't remember the name.

Tell me more of this roll on plaster of which you speak.
I am OK with boarding (I use the dot and dab adhesive) but can't skim for toffee.

2 coats of polycell basecoat will sort your walls out after stripping, spot filling and sanding

WHS.

PVA is a gift from God.

If you are putting plasterboard over the wall anyway, then seal current surface with watered-down PVA (1 part PVA:5 Parts water, I think, but instructions on the container). Then, PVA plasterborad on top. I use undiluted pVA for gluing - it's a strong adhesive, as long as it remains dry. Else, get waterproof PVA. Oh, you can get roll-on plaster, too, which I found to be a doddle to use and saved me £100s.

Old paint isn't a problem, they just put watered down PVA glue over the top of it just before plastering.

I've got a high powered DeWalt belt sander that a previous workman left and if you are trying to flatten out bumps in the wall it is the jobby. The dust collection is a waste of space, tape up the door edges, open you windows and prepare for a hell of a lot of dust that will linger for weeks.

What roots said is true too. PVA is used. My guy used a weird green stuff with small bits in for the plaster to key to.

Have you spoken to the plasterer? He may just need to score the old paintwork to give the plaster something to grip.
If the paper stuck to the paint the plaster probably will. Get advice from your pro, not a bunch of DIY experts like us.

If you must sand then get an offset orbital jobbie DeWalt do a good one. You want a high powered motor.

Watch out for chemical stripper. Some can't be plastered over for months.

paper is off, 2 layers of old paint is still on... I was going to sand it unless there's a chemical option

You should not need to sand them down if you are filling and skimming. Your plasterer will do all the prep work they need. You just need to get off all the old wall paper and paint.

yeap as TLG says you dont need to do anything but strip the walls if chunks of wall come off with the paper the plasterer might need to do a bit of bonding, but thats what your paying him for

[The Lone Gunman]

I need to sand down a couple of walls prior to filling/skimming/plastering and eventually painting.

Which sander does the panel recommend for a quick and easy job?
Needs to have some sort of effective dust collection as well


I AM NOT doing the filling/skimming/plastering myself - I do know my limits
So no comments on how difficult getting that right can be.
