ideas sought for mounting boards to concrete sectioned garage

Hmm, possibly answering my own question ...

I have now discovered 'garage lining clips', which might be exactly what I want ;-)

Butter the back of the OSB with low expansion "board fix" foam, dampen the wall, push it into place and prop it for a bit. It will conform to an uneven surface, and sticks like the proverbial to a blanket!

I assume that each wall section consists of a number of framing members (vertical and horizontal) with thin set-back panels such that the whole thing is flat on the outside. If so, why not fix some battens to these thin panels with a thickness which makes them level with the framing members. I suggest screwing the battens from the outside, using screws with metal and rubber washers similar to those used for roofing panels. For belt and braces you could also use Sticks like Sh*t to stick the battens to the panels and also to provide an additional seal round the screw holes.

You can then screw your OSB to the battens without the framing members getting in the way.

Hi John That is an idea, thanks, although I will have to work out how to 'prop it for a bit'. Would this result in a panel able to carry a reasonable load?

Cheers J^n

It should so - especially if the board goes down to the floor. The technique is quite often used on plasterboard in place of "dot 'n' dab" these days.

The "prop" bit is only to make sure the edges set at the same level if doing multiple boards at once. It goes off in 10 mins or so. In a garage, and long batten that could be sprung in between the walls should do the trick.

So handy info here:

Hi John Thanks for this. In fact I have a mild preference for the OSB to

This will lose a bit more space than the OSB straight onto the concrete approach, but I can live with that.

I am sure I will find a use for this low expansion foam method elsewhere

- I want to put up a board for a French Cleat system - so I am watching the video with interest.

Thanks again, J^n

Hi Roger Thanks, but the construction is not like that at all. It is entirely of concrete sections, bolted together with a steel frame and roof on top. The sections are not practically drillable.

You can see something of the construction in this image:

Cheers, J^n

Yes, it's a good video - a lot of the tips/tricks I learnt the hard way ;-)

In fact I've used ordinary expanding foam for low risk fixing like skirting boards - seems to work well.

You can add angle brackets, flat face outwards, to the section joining bolts.

Yes, that was a thought I had originally. But I feel that then screwing to those would be tricky to get right.

The garage lining clips I have now found seem to be a better plan, to me:

(although I am going to make my own...)

Followup to my original query:

I ended up repurposing some standard 75mm tee brackets to use as 'lining clips' - I drilled an extra hole for the 8mm bolts that are used to hold the concrete sections together, and put a shallow (150 degree) bend on each.

I then cut down some roofing battens to make some timber lengths around

I was then able to screw through the OSB sheet I wanted to use as a panel, onto the lining battens.

It's not a super-elegant solution but is cheap and cheerful and has allowed me to to mount a vertical bike rack, which is where I started from.

If I were to do this again I would probably also use some adhesive in a cartridge to ensure the battens are secured to the concrete and don't 'flap about' at all. I did look at my selection of old cartridges but they have all cured ;-(. There is very little play in any case.

Thanks for all the suggestions anyway J^n
