Diy plaster project

[Waineruk]

Hi all,

First off, thanks for all the contributors on here...I've learned loads this weekend...albeit I'm yet to touch plaster with a trowel...

So I'm going to try diy plastering on a 4.5 x 4 room...walls and ceiling..

The paper is off and I have sanded and filled and sanded again all areas with 40 grit paper..

I'm about to pva and then I guess the fun begins...

I've a couple of questions I cant find the answer to here- I must point out my house is cast in situ concrete so hopefully it makes more sense of the questions

I've removed a internal door frame between connecting rooms - do I brown/ bond the exposed concrete and before it sets add in edging strips? Ready for skimming

Second Q I understand I have to get everything on the ceiling asap - based on the size of the room should I mix two buckets ready with 1.5 bags of plaster in each? Then skim the ceiling and a small wall? Perhaps the side of the chimney...

Thanks for any help...

Don't try and put a ceiling and a wall on you will struggle hard enough with just ceiling....also @gps thinks your a liar if you do 3 bag sets on domestics

 

[malc]

you can bed the beads first or push them into the undercoat while it is still wet.
your property build is called nofines, poured concrete.
3 bags is plenty to mix on your own in a domestic situation.

don't forget to post some pics. plastering is easy enough there are even girls plastering these days !

I think it was YOU don’t do 7 bags average a day in domestics.

Edited that’s all I’m saying

Thanks guys...so how many bags do you recommend for just the Ceiling assuming a two mil covering ....and me f***ing up several times

 

[Mouldyoldspudgun]

About one and a half bags do one first get it on then knock up half and top coat it, I assume you are a beginner, if so do a wall first to make sure you can handle the ceiling

I must say it’s difficult watching you deteriorate like this.

I think it’s time to put labels on your hand tools , ‘trowel- for plastering’ ‘handboard, put plaster on here’ etc

You assume labels are not in place already.

Yes I agree with @malc , plastering is dead easy, but you’ll struggle to look at all pretty while you do it

Pics please when you’ve finished! Good luck and welcome to the forum

Hi all - I've a quick question ahead of my weekend of plastering madness - the "window wall" and the window has timber reveals- I cant remove them, new windows were put in in in and they put a pvc edge around them and attached to the timber ...can anyone give a good idea of how I can plaster over the timber reveal edge? Should I scrim, pva and then skim? I've attached a pic....this all around the window....

 

[beader]

Skim up to the timber and fix an architrave around to make a feature.

 

[Mouldyoldspudgun]

Why do you want to plaster over the wood? Just put an architrave around it

 

[lurpak]

Thanks for the yellow arrow

 

[Waineruk]

True, ideally I wanted a clean look...flat ideally..

 

[Waineruk]

Thanks for the yellow arrow

You're welcome...glad you like

 

[Danny]

I would architrave it.... but...

You could chop the reveals back and mesh and backing plaster and then skim... it will still probably crack though

 

[lurpak]

Shouldn't skim over wood but I've done a few reveals like this where they want the flush look without architrave but don't want to strip the frame.

If you want to do this, scrim the crack then tight coat of bonding top to bottom.

Then put an angle bead on and scrim that, then skim.

Never had one fail doing it this way, but as said.. is a bit rough.

Thanks! Would it be a stop bead? Or an angle like you mention? Can't figure where the other side would sit....

post a picture of the whole window so I can advise

 

[Waineruk]

Here you go...

[lurpak]

That’s exactly how this one was, previously architraved looked grotty.

Remove plastic trim inside and tac 9.5mm plasterboard around .

Angle bead all around and do as I mentioned above..

Or save yourself a headache and re-architrave

 

[Waineruk]

Great thanks...I'll give some thought before I start the wall ...much appreciated!!

 

[Danny]

scrap my previous idea... angle bead and go for it

Don't worry mate your Guna f**k it up regardless!!!
