We have this footrest for my partners home hair salon.

The floor is vinyl plank on a rib raft concrete foundation and I'm not confident drilling into the foundation myself. Would there be any other way to secure it to the floor that wouldn't come loose (silicone or glue?)?

Thanks

You could just glue it with No More Nails or similar. I had some pieces of timber glued to my garage floor in this way and when it came time to remove them, they took some shifting.

I thought about that, my only concern with that would be could a hard knock then pull up the vinyl? Or are the planks generally glued down hard enough that this wouldn't happen?

Consider 3M Dual-Lock https://www.3m.com/3M/en_US/dual-lock-reclosable-fasteners-us/

It's velcro on some serious steroids. I used some to mount a 20" LDC screen for a camera system to a brick wall for a client when the monitor had no mounting holes. The client was a signage company, and they had this product laying around.

A year later the screen died and was being sent back for a warranty. After my first attempt, I advised my client their warranty might be null and void as after my first attempt i had real concerns that the back of the screen was going to break away before this Dual-Lock let go. I did get it off in the end, basically by hanging off the screen.

Is it just for use with a seat? Could you put down a section of plywood that the seat and foot rest attach to? Gluing anything to the vinyl will likely damage if it removed. No more nails etc should hold that to a section of ply. No damage to floor that way.

I think you're meant to release this stuff by sliding something like a steel ruler between the layers to release them.

My concern with gluing that to the floor is that the pressure on a footrest like that is not going to be straight down. People are going to push against it, lean on it and step on it getting in and out of the seat and so on.

It's one of those things I would not try anything other than bolting into a solid base...FWIW I was a hairdresser for 13-odd years a few decades ago and saw many interesting breakages from "normal" use in salons.

I have to agree with @Handsomedan - adhesive or strips aren’t the best solution if you’ve got diagonal or horizontal pressure - someone could get hurt if it moves or slips.

I would put three coach screws, say 30-40 mm, through the three holes into the floor. The bolt-type heads on the screws give you a good solid drive to install or remove. All you need to do is drill three holes a little smaller than the screw diameter and drive them in or screw them in with a small spanner. These would be more than adequate for what you want.

This link is just to show you what they look like - couldn’t find a decent link on Bunnings or Mitre 10 sites - but you can buy these individually for a few cents at both those places.

There is a bunch of rebar right under where the footrest needs to go - I might not hit it but I'm not confident enough doing it myself. Builder said he could come and do it, but suggested an option for me to try myself first is to remove a section of vinyl slightly smaller than the foot rest base, and then liquid nails (or similar) to stick it directly to the concrete. This should prevent the vinyl coming up if someone put too much pressure on it.

If it doesn't adhere properly, or comes off, then we still have the option of bolting it down as the foot rest will cover any hole we cut in the vinyl (and regardless of how we do it, the vinyl planks underneath would need replacing if we ever remove the the footrest).

It seems like a reasonable option to get it done more affordably and sooner (builder is booked up).

Thanks for the suggestions.

Sorry, missed the fact that it’s concrete. Therefore substitute small Dynabolts for the coach screws - but you will need a masonry drill bit to do that, so not quite as simple.

As a simpler alternative to Dynabolts, these things work brilliantly for your type of job. You could go with a slightly shorter version than those shown in my link. Although it says “light duty fixing” they would be perfectly fine:

The mounting holes are 10mm, so I don't think those will be wide enough unfortunately.

If bolting then I think dynabolts would be the only option. If it was just steel mesh in the slab i'd be happy to give it a try, but knowing there's rebar pretty much right where I need to drill makes me nervous about attempting it myself.

@handsomedan I know what you mean about breakages from "normal use", but how this will be positioned (right by the wall under a bench) I don't see that anyone could use at as leverage while getting in and out of the seat.

Worst that will happen if you find the rebar is that you'll stop being able to drill further. Drill bit might get a bit blunt too. How deep is the rebar? 50mm of depth should be enough for fixings for something like that. What area are you in?

In Christchurch.

It's 100mm of concrete above the polystyrene pods, and the mesh is on 65mm chairs, with the rebar wired to the underside of the mesh. So I guess that puts it at 35mm deep.

Hmm... just came across the drop-in anchors.

https://www.bunnings.co.nz/ramset-10mm-dynaset-flanged-drop-in-anchor_p0886261

Only need to drill 33mm. 10mm thread which is about right. Only issue is that it's flanged at the top, but the thickness of the vinyl might take care of that?

Or this:

https://www.bunnings.co.nz/ramset-dynaset-drop-in-anchor-8mm-zp_p0648371

Also only need to drill 33mm, but only an 8mm thread where the mounting holes are 10mm - but if the head is a bit small I could just use washers on top couldn't I?

Would either of these be suitable?

I didn’t know those things existed. Look absolutely spot-on for your job - excellent. Go for it. The 10 mm version is probably the one you want, given the holes in your mounting plate.

Damn it. The drop in anchors say they require a Dynaset Setting Tool.

Bunnings has the anchors, but I can't find anywhere that has the setting tool. Ridiculous.

EDIT: What could I use instead of this? Looks like it's just a rod used for hammering the plug in.
