 Post subject: Expired Bonding/Hardwall plaster -use?
PostPosted: Sun Dec 17, 2017 2:46 pm 
I was on homebase today I there have a pallet of BG Thistle or Bonding Plaster. Free to take away. Forgot the exact one (brown bag I think)
Anyway date is July 2017. Two Q's

1) Would you still use it? Bag looks fine and I only have some blown sections to repair?
2) will the bonding coat still on brick and sand cement render?

 Post subject: Scrimming on a Rebate
PostPosted: Wed Dec 13, 2017 12:35 pm 
I have been advised before applying plaster to my new patch, to chisel around the border of the existing plasterboard. This would mean the tape will be in this rebate rather than over the joint. The advantage of this is less plaster on the joint.

 Post subject: Plasterboard thickness
PostPosted: Mon Nov 20, 2017 11:00 pm 
So todays question... which plasterboard thickness to use...?
Is there a rule of thumb as to when 9.5 is better than the 12.5...?

Doing a bungalow loft conversion, hallway needs overbording... already has 12.5 boards and artex on most of it...

Bathroom ceiling, same as hallway, small room, 1.7x2m...
New joists above these two are at 300c/c...

Main part of the loft conversion is 12.5+25 insulated board, but the internal studwork, eg from new landing ...

 Post subject: Plastered Walls were dry but now look damp
PostPosted: Mon Nov 20, 2017 9:20 pm 

I've been getting a house plastered. Some places have been taking a very long time to dry out. A wall that had some vents blocked up, so i guess the cement wasnt fully dry before skimming.

Over the last week or so, rooms that were dried out now start to look wet again in places.

Ive had windows open to stop a build up of moisture and airflow to help dry out for weeks, ...

Just out of curiosity after a first coat has been applied, do you trowel it up or do you move straight onto the next coat?

Also whats your average time to first coat a wall of say 10 ft x 7 ft

 Post subject: Hairline cracks
PostPosted: Mon Nov 13, 2017 8:44 am 
The bathrom had tiles on them which I removed and in doing so removed the final skim of plaster.
The section that needed needed a new skim was not large though more than pollyfiller could do.
I watched various youtube vid's on how to apply a final skim to give me a heads up.
I cleaned the old plaster on the wall and applied a 2 to 1 mix of pva to the wall.
Once ...

 Post subject: Help with new plastered wall
PostPosted: Sun Nov 12, 2017 8:16 pm 
Hi guys,

New to the forum and after some much needed advice. I recently had my whole house skimmed which didn't turn out as expected. Lots of uneven walls, bumps etc. Not the best job and these guys were meant to be professional plasterers.

Couple of questions, would using a machine sander help even this out? And secondly, what can I do with the wall in the pic?

 Post subject: Expanding foam to fill a gap in a new ceiling
PostPosted: Thu Nov 09, 2017 12:46 pm 

I have had a new ceiling fitted (plasterboard) but this was cut short of an edge by the staircase, I would say that the gap is around 7cm x 47cm This was mentioned to the builder who was going to rectify the issue. On my last visit to the propery I notice that the gap has been filled with expanding foam and a bonding coat has been applied but some of the expanding foam ...

 Post subject: Plaster going off in different areas quicker than others
PostPosted: Fri Nov 03, 2017 1:53 pm 
I am a amateur at plastering but I decided the best way to learn was to get in there and start on the smallest bedroom in my house then progress to the bigger ones.

I have done a ceiling and my 4th wall yesterday, the issue I seem be coming up against is the plaster going off on some areas of the wall quicker than others, I can't understand why. Would it be just down ...

 Post subject: Artex
PostPosted: Sat Oct 28, 2017 8:21 am 
Yes that topic again.
This house is full of it they even managed to coat a wall with it, however the builders are removing that wall and a couple of others.
That job is beyond my skill level.
However the options on the ceilings are either to have a plasterer come in and re plaster the ceilings or have the builders line the ceilings with plaster board or try and remove the artex with that ...
