I am not able to put permanent fixtures on these walls. It is trust rules as it is a historical building that was built in 1863.
So, I tried command hooks and it will not stick nor hold firmly to the material. I cannot drill holes either and use masonry nails. I cannot superglue anything to the walls.
Issue is I really need to put these two MDF boards up. Using Blu tack could be an option but again will not stay stuck to the walls.
I cannot use liquid nails. There is also some heavy stuff I need to hang.
I'm truly out of ideas. Suggestions would be helpful. I'm also wondering if outdoor non permanent backing tape could work as a possible solution. I would still need to hang some things though.
Re hanging your two mdf boards, have you had a look at this type of support, I have used a similar product, available from Bunnings to hold up photography back drops, mine were used in the vertical position from another supplier, I didn't want to mount anything permanently, these props are adjustable to fit tight between two opposite walls or ceiling to floor.
If you need something to suit the area, you could make an adjust timber beam that fits snuggly in between the walls with adjustable screws and pads (to prevent damage to walls) for the feet/ends, then just mount your mdf boards to it, however, I not sure if your walls would be strong structurally to hold the timber beam. @MitchellMc you maybe to to assist further.
Images of the following are my vertical installation.
It's certainly an interesting predicament @Wouldy.
The command strips wouldn't be holding firmly due to contaminants or powdery plaster on the wall. Instead of sticking to the wall, they bind to the contaminants and then fall off. You could try cleaning the area you intend to stick the strips onto with an eraser pad to remove dust, dirt, and residue. After using the eraser, rub the area down with Diggers 125ml Isopropyl Cleaning Alcohol and allow it to dry before trying again.
I do like @JoeAzza's idea of creating two vertical poles, one on either side of the wall, and running wires between them to hang things off.
I look forward to hearing about a solution.
I really like your idea and actually would use it. Issue is an incredibly high roof and it is like a loft roof. Great idea though!
Great idea @MitchellMc
Unfortunately I don't think it will work. Rubbing these very old walls with anything would cause them to flake. I'm going to get to the drawing board again.
I think I have come up with an idea. I will get some wire and a rustic looking idea to do with the things I need to go up. There is some pre existing holes here in the wall. I could use them and hang things from the wire.
That sounds like a brilliant solution, @Wouldy.
Please keep us updated. I trust our members would also like to see your results.
I realised although a good idea and I would have gone with it, I've come up with another idea. It will suit my aim and look better aesthetically with other things.
Once I have it done, I promise I will put photos up in here for other members.
