Any one used thistle bond plaster?

oxygen_old

I hope no one bites my head off, since this is kinda my second post about thistle bond. I just want to know if anyone has used it before? Some plasters seem to know about it, some look at me blankly when I mention it. My house has been rewired, chasing needs to be filled in, then plastered. Thistle bond is my preferred option, since there are several cracking layers of paint on the wall. I would prefer using thistle bond, as slabbing will loose a 3/4 inch from a wall, each side. This is a pain when you think of moving the rads, fitting doors etc. I also assume thistle bonding would be allot cheaper...

Is the following feasible?

Steam any wall paper from the wall.
Sand any loose paint
Thistle bond the walls
Skim the walls
Decorate

thanks

Seen it used loads of times on sites. Seems to be a good job and i never heard any skimmers ever complain about it.

Do you need the bonding? It will make everything thicker. Are you going to knock off the old plaster?

Note that the bonding could take a while to dry, before you can really put on the skim coat. To avoid this, or at least reduce it, you can use the bonding to stick pieces of plasterboard to the wall. The plasterboard obviously doesn't need to dry out. It also leaves a good surface to skim onto.

A decent plasterer who's worked on old houses will know what he's doing here.

Some plasterers (fewer and fewer) have only ever worked on new builds. These plasterers are unlikely to be a great help to you.

If you feel uncertain, get the guy to do one room or one wall through to completion first and decide if you are happy before you go crazy on the whole house.

I'm certainly not a plasterer, but I've gotten a few jobs done in my time.

thanks newmills. Since it was on a site, Im guessing they were nice new even walls?

The problem I have with plasterboard is it adds a half inch to each side of the wall. In the cases like door frames and stuff, this is a bit much

But you're going to have the same problem with the bonding. It will end be hard to get the bonding to be consistently less than half-an-inch thick, I think, though maybe it can be done. Bonding has a thick consistency

Are you going to knock the old plaster off the wall before putting the bonding and plaster on?

What is the construction of the walls?

What state are the walls in generally? Rough? Smooth? Plaster solid or falling away? You mention that there are layers of paint. Without a doubt, anything that is even slightly loose will have to be scraped off to provide a solid base.

If all it needs is a skim, you don't necessarily need to put any bonding or plasterboard on there. It depends on what you are plastering onto. But different plasterers will have different ideas about how to deal with this.

Would it do to just fill in the chases with bonding (which is what I think you are calling thistle bond) and skim them? This is a small job.

Whatever way, a good plasterer should be able to sort this out for you without much problem.

I don't mean to dredge up an old thread, but this is similar to my dilemma.

We're renovating our old redbrick and, despite my firm instructions to remove wallpaper, make good and re-skim as many walls as possible, the builders have basically slabbed the whole house. They did not remove any old plaster in order to then apply the slabs in a way that did not interfere with original room size and original features by essentially replacing 'like thickness' for 'like thickness' (architraves especially).

They said walls (which were the 'good' walls) couldn't be skimmed; they immediately discounted Thistle Bond-It, etc. for some reason.

This has meant that door architraves and stair wallstrings have been swallowed up by the extra plaster layer and, in my opinion in many cases, the unnecessary additional layer of plasterboard.

Some more detail, some upstairs old lath walls have had this additional plasterboard layer fixed to it and I wonder if the right thing to do would have been to remove the lath and plaster alltogether and fill the wall and re-slab so as not to add any further depth.

The job is really, really terrible and I'm not paying for it.
