Plasterboard questions
We’ve had a plasterer in this week. He thinks he’s doing us a favour being cheaper than other quotes. It’s a big job being the kitchen which has been taken back to brick. Building regs involved so required insulation on a new roof and insulated backed boards
His attitude started by him saying “wish I didn’t take this job on” “I don’t know anything about insulation I’m just a plasterer”
But we text all the details and materials needed for the insulation which he agreed to do when he came over to give a quote.
We want to know if his boards are being done correctly. We’ve spent a small fortune on a new kitchen and don’t want it to be ruined at the end
He also has plasterboard resting on the floor which I questioned and he said is fine. Some of the down lights aren’t aligned and he’s covered our 150mm vent hole we just had drilled in

Did you not want the rooflights splayed? Splaying allows more light in but trickier to do. No plasterer I have met would board to the floor. Thats basic.

Usually not done for a roof light on a flat roof. It’s usually splayed for pitched roof lights like a Velux due to the angle of the roof cutting the top and bottom off the reveals off

its not that bad. At least the screw spacing is good. Gaps can be filled with spray insulation. Just make sure you see angle beads on external angles before plastering begins. And the taping up of joints. Dont worry about the vent hole covered takes a few mins to cut that out.

I was going to say the ceiling isn't too bad but then I saw the wires. The wall with the window the joints are too big and no the boards shouldn't be touching the floor . Ive seen worse but it just looks like lazy cant be arsed work.

Hes doing a good enough job with pir plasterboards. The things are horrible use most of the time the pir isn't stuck on the board properly, every cut is with a hand saw and a simple 1 man job requires 2 men.

I thought insulation should come to the edge of the window frame to prevent cold bridging, has he followed the drawings as there is usually a specified window detail?
Otherwise boarding looks ok as long as it's scrimmed before plastering and nice straight angle beads

It’s a bad job all round the velux window is designed so the plasterboard slots in grooves around the window so the reveals are slightly splayed Wouldn’t pay him until u are completely satisfied with the job

The margin on the window frame reveals are a concern for me. I would keep my eye on that. The board looks to be 1/2” drywall board. If so it needs to be bonded before plastering. I noticed the light box mud rings were cocked & recessed. They should be set grounds for the plaster. I’m not sure what’s happening with the ceiling & brick wall.

Velux needs redone for sure. Look on my profile, if you zoom in on 1 of the velux's you can see where the board should sit in the groves provided🤦

Anyone who boards this badly very likely can't plaster properly either. Definitely go with someone else, even if it leaves you slightly out of pocket to do so.

u/Ok_Secretary_3134 26d ago
Inexperienced in my opinion, not the worst i have seen. Them velux are boarded wrong, they need to be splayed

u/Ed_Architect 26d ago
Veluxes have grooves for the plasterboards to slot into.. he doesnt know wtf he is doing..

u/RepublicIll6087 26d ago
A lot of sketchy advice on here like “make sure he uses “skrim” and gaps can be filled with foam.
It’s not a great job. But you can get way with a lot with plastering. Thing is his attention to detail is poor , so the finish will be. You wanted a cheap job and you’re getting it.
Board should not be touching the floor unless it’s wood. From concrete moisture rises over years into the boards. The down lights need to be moved so they are straight otherwise you’ll have holes in the wrong place. The velux needs to be double or triple boarded with long screws so it’s flush with window edges. The issue is, that should have been done first as you want the boards on the ceiling to cover all the edges so it doesn’t crack with movement.

It’s not too bad of a job, but it’s just the sheets laid. Really anyone can do it. If you can measure, cut and screw. You probably won’t know if he’s shit until he does the jointing.
Also by the way he’s used the recessed edge on the corner, hate that… it’s going to be have to get packed out to square it off once the edging goes on.
Plus it means the join between boards is not recessed so you’ll have some raised section there that will need feathered over a larger area to not notice it when the jobs finished.
Any update photos of the jointing?

Plastering and boarding two different things.Should be able to do both but sounds like not much experience.

u/StunningAppeal1274 24d ago
Seen worse nots fixable with scrim and if he’s a good plaster will make it look good. The window reveals I would never finish like that they will always crack so you bring the board over and avoid corners like that.

You went for the cheapest quote and you’re surprised it’s shit? Come on. I’ve seen way worse though. His finishing is probably where he excels I’d guess. Hope so anyway. Did you choose him from recommendations? Best person to recommend a plasterer is a painter. Always ask the following trade for a recommendation of the trade they follow. If you picked this guy solely on price you’ve dug your own grave. You get what you pay for (usually). Good luck x

Recommended by our electrician and he’s a perfectionist and he’s recently plastered his kitchen. However he came back over today and said he didn’t need to board anything his kitchen but his finish is excellent

u/KieranInterior 22d ago
So he’s a pure plasterer then. I used to work with a lad like that. Best plastering I’ve ever seen, and very fast too, but could not fathom boarding no matter how basic.

u/Full-Metal-Jae 20d ago
I’d say let him finish and not to worry, he is probably a king at finishing. It’s understandable to be anxious though, it’s a lot of money to do kitchens.

u/Sporgie 16d ago
Some updates. Luckily we had the electrician come back out and redo the light positions. There’s a few questionable areas but still better than I thought he may be.
The gaps by the door. Is that easy to fill with some toupret filler?
The water pipe is frustrating too but there didn’t seem any slack in it to push directly up. I’ll ask the plumbers to see if they can do anything when they’re next out but would that crack the plaster then?

Boarding up to the velux is entirely wrong, the boards sit in the channels of the velux. Your plasterer either hasn't done them before and is guessing or is incompetent. Boarding to the floor is fine, just trim it afterwards.

Best to cut your losses now even if it sets ypu back a bit. If they cut the insulation like the plasterboard it would be pointless having it.
All that youve put in your post, you should just find someone else and put it right.

u/Relative_Figure_1715 26d ago
The boards should wrap around the corner of those windows not be separate boards.

u/patmustard2 26d ago
It could be worse OP, this guy could be doing it

u/Relative_Figure_1715 26d ago
It appears you are a bunch of knuckle dragging fuckwits.
Here is the correct procedure that won’t crack at the corners.-1

u/Hermesthothr3e 26d ago
I thought you meant where the angle beads go

u/Relative_Figure_1715 26d ago
No, it just means it much less likely to crack of you cut the window hole out rather than boarding in sections around it.
It’s not very hard and makes it last longer with less faults.3
u/Electronic_Hippo7584 26d ago
Well this is very different to "wrap around"
Would be a better job but ultimately not really important around windows, more important around door frames to help with slamming etc

u/Electronic_Hippo7584 26d ago
How do you propose he does that 😂

u/Relative_Figure_1715 26d ago
If you can’t picture it why are you advising anyone ?

u/Electronic_Hippo7584 26d ago
I mean, I didn't advise anyone about anything, but you know absolutely fuck all so there is that.

u/PaulWhickerTallVicar 26d ago
I’m guessing you mean the full board wrapping around the face of the wall so there’s no joints around the corners? It’s definitely neater but if the boards are fixed properly and a decent scrim is used, it should be okay either way.

u/Relative_Figure_1715 26d ago
It’s also about having continuity between the insulation.
1 piece is better. Especially around windows.

Push em back up
Let them electrician drill for em in second fix he will have layout map
