r/Plastering

UK based, 70s flat. Doing electrics and stripping walls for redecoration. Some of the sockets were quite badly chased in so we’ve been sorting that, removing the old plater job also pulled away some of the blown material.

Ontop of the brick is this render/plaster with a thin layer of grey speckled material (concrete skim?).

Just trying to figure out how to repair the chases and then also prepare the rest of the surface for painting. Most of it had a few layers of paint or thin plaster which just peeled right off.

Complete novice by the way. What are the next steps from this position right now. Do I plaster the pieces missing or would filler, sanding then painting do the trick? Thanks in advance.

I had a tadelakt shower put in a couple of years ago. About a year ago I noticed a small amount of mold which then became larger. It's only here and a little bit in one of the corners. I haven't used it for weeks. I noticed that the grout on the tile is chipping, and water is probably getting behind the wall. My question is: what do I do? Will I be ok if I can get rid of the mold and re-grout the tile? Do I need to get the whole thing re-done?!

The plasterer whose team did the work have run away with their tail between their legs and will not come back answer our contractor or our engineer.

Our engineer came to do a report, but was incredibly quick, didn't check for hollow patches and is good friends with the contractor and has been friends with the plasterer.....so any advice would be very much appreciated.

Feels like he isn't working for us at the moment to be honest.

We have had another plasterer look at it for us to see what he thought, no skin in the game so knew he would offer his own opinion on the matter. He felt it was applied in one skim, not two, and was overworked to try and get a finish on it. So anyone who can offer any input is very much appreciated.

Have another guy who offered to have a a look for us this week too.

The electricians passed comment on the plaster being very crumbly when they were working. We had a lot of holes left around sockets/switches.

Our contractor insisted we prime the entirety of the house after we raised the issue on the first wall.

Products we know that were used:

•baumit

•thistle bond -multifinish

• thistle bond - bonding coat

Completed in 2 days by a team of 3, one labourer and 2 guys skimming. 70sqm house.

Includes 3m high ceiling in one room, with 7 rooms, lots of little ins and outs.

Our house was skimmed over sand and cement the end of January.

Been well ventilated and was moisture tested prior to applying anything to the surface, tested by the contractor for us.

Prior to priming the walls with a primer designed for bare plastered we had consistently noticed unusual patches on the skim. Some looked almost like finger marks as if someone had run their hands in a wavy pattern , some looked like scratches, and some patches were intensely shiny, others very chalky.

Since priming, have areas will not absorb, although entirely dry. Raised patches were the very shiny patches were. The areas that looked like finger marks are clearly bow the devil float marks coming through. The have matched them off photos of the scratch coat.

The scratchy marks are very clearly brush bristle marks.

There are areas when tapped you can hear hollow areas. Some of which have cracked.

Cracks are widening even with ventilation to prevent heat build up in the house. There have been some small chunks that have fell off in the last few days too.

All the corner beading has oxidised and rusted, and the mesh grid of the beading is visible and can be felt by touch through the skim.

So many of the screws in the timbers have been exposed as the plaster put over them has popped out too.

The patches are consistent through the entire house.

They have tried to blame EVERYTHING under the sun. Began with the primer, but they have all agreed the primer isn't the issue. Tried to say it was an alkali issue. Having researched this, it can't be that, also doesn't present this way. We even tested plaster dust after reading up how to and it is testing neutral.

When the plasterer did initially pretend he cared and would fix it the kept mentioning how it was definitely two skim coats and not one (when we had no mention or information at the time that it possibly wasn't, which feels very much like a "if we say it enough they'll believe us")

All the research we did when this first came to light around 3months back has pointed towards poor application. Which upon reading up points to excessive cracking, brittle skim, the patches keep coming through even after sanding/painting and even delamination.

Right now it feels like we are possibly facing all those things when everything gets added in.

My old 137 year old house still has some lathe and plaster ceilings this one has had the same crack since we moved here 3 years ago

Is this a danger to falling down? Can it be repaired without overboarding? It's a listed building so has to stay the same ish

I want to put access panel over valve. I have no idea how to restore the area above the valve and frame it for access panel. There is stud on left hand side, visible. Stud on the right is about 8 inches deep into right hand side. This looks like 1/2" drywall with some kind of thick plaster on top. House was built in Maryland in 1960. Should I put a flush mount panel over the entire area (15.5 x 18.5)? Should I add plaster on the exposed drywall area on the right hand side and put flush mount panel 12x18.5. Or should I frame the whole thing for a 12x12 panel?

Hello, I have a textured finish plaster ceiling that I’m attempting to skim coat in order to flatten the surface. I haven’t done anything like this before, so I’m a novice here.

My two main questions that I’m hoping someone might have experience with:

1. Would you try to sand this down further?
2. Would you apply a layer of primer prior to applying mud?

I just want to prepare as well as I can before trying to skin coat. For reference, the area is about 150 square feet and the texture is in pretty good shape.

Hi, just wondering if anyone can bestow some knowledge on what is going on with this wall. Roof is fine no leaks but there is rendering on the brick if that matters.

Looking for some advice on this large crack in my ceiling. Would this require a skim or would it need a full plasterboard replacement? Any advice on what to look for what be great!

Plastered my first wall today. Enjoyed doing it but wondering if I could get any advice from the pros? I pva’d the wall 24 hours before then about half hour before I skimmed it. Cheers👍

Need to try get the same texture but I dunno how

I've stripped the wallpaper and this is the wall behind it, just wondering if anyone knows what kind of plaster it is and can I pva and multi finish over the top. Thanks
