How to cover a rough internal brick wall?

[Northy]

Good morning

I would very much appreciate some advice to.assist me with covering the internal brick wall in our living room. I have had 2 attempts affixing plaster board with Gyprock Masonite adhesive but it has not stuck. I followed all the instructions. The bricks are quite rough. Wondering what else to try and whether plaster is the best options. 

Thanks

Hi @Northy 

Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about covering your internal brick wall.

I'm surprised that the Gyprock adhesive did not work on the brick wall. Did the panel just peel off? I'm just after some additional information as to the possible cause of failure. When the board came off was the adhesive still wet? Any extra information you can provide about the installation would be very much appreciated. One other method you can use is to install timber battens on the brick wall where the gyprock can be anchored onto.

Here is a link to an installation brochure using timber battens: Gyprock Installation

I would also like you to double check this installation guide and let me know if this is the guide you followed - How to use Gyprock Plasterboard to cover a Masonry Wall. 

If you need further assistance, please let me know.

Thanks Eric

I think the issue was/is that the wall is not straight. The adhesive stuck to the plaster and the bricks but pulled apart and therefore came off the wall when I put pressure on one side (if that makes sense). 

Can you tell me more about a timber batters. Like what size timber should I use.

Hello @Northy 

I suggest looking at using 70 x 35mm Framing MGP10 H2 Blue Pine 2.4m on your brick walls. I also suggest looking at these discussions - How to attach wooden battens to a brick wall by @JohnN3 and What size battens for double brick in garage by @mossy_74. These discussions should give you a very good idea of what you'll need to do to attach the battens to your brick wall.

Let me call on our experienced members @Dave-1 and @Nailbag for their recommendations.

If you have any other questions we can help with, please let us know.

Good Evening @Northy 

Sad to say I have seen very few bricks that are level to the 10th degree

I built a false stud wall next to my brickwork in the garage, Made life a LOT easier doing so then fixing plaster to the bricks. (I did fix some of the plaster to the brick work using the blue plaster glue (Goop) compound and that has held up well.

Garage lining for stud walls stage 1 is the false stud wall project I did.

If you are worried about loosing 70mm you could actually make the false stud wall out of the same timber but flat so it only comes off the wall by 35mm.

Hi @Northy 

The first observation is that it appears your haven't used enough masonry adhesive.This is how I would suggest you do it which is the technique I used in a lower level space I converted into a bedroom as per the photos below..

1. You will need a 125mm angle grinder fitted with a Diamond Cup wheel.

2. Hone down all the high-points as well as the old glue spots. This is going to create a LOT of dust. So use good quality drop sheets to seal the areas from the ceiling to the side walls. A workshop vacuum will help to keep the dust to a minimum as well as being used to clean the debris afterwards. You will also need full body PPE. I straight edge will indicate any major high-points needing honeing.

3. Use this masonry adhesive to fix the new plasterboard. Run continuous vertical lines every 500mm and across the bottom at 1200mm. Fix the plasterboard sheet and prop in position. Once set do the top half the same.
