Glues/Adhesives

[Third From Texas]

Been looking for something to glue my Sika board insulation to the walls of the hab. I was going to pick up some Sikaflex 552 but nobody local has any.

Suggestions?

Liquid Nails?

Etc?

Also, I need to come up with a kitchen splashboard. I'm looking at a few tile options, but again I come back to glue/adhesive. I know RVs typically use a "flexible" grout (which as best I can ascertain is just tinted silicone). Some of the tile stuff I looked at was really heavy and I put it back as a result. I don't know enough about what it will take to glue it to the wall and what to use in place of grout.

@chucky you're rockin kitchen tile, what did you use?

Elasticity and elongation of similar match would be preferable. I am not sure Liquid nails or Loctite would stand up to all the flexing and might introduce failure over time. Not in stock per say; but delivery early September. There's Sikaflex521

Never waste your money on anything liquid nails . Lowes stock the loctite 3x in the big 28 oz tubes alot more economical just pick up the big cheap caulking gun for big tubes and sikaflex is great but more for outdoor adhesive

I used liquid nails construction adhesive for adhering wood to metal all the time. These were mobile applications for on and off road use. I found out during removal it was easier to just leave them in there as the wood would break before the adhesive did.... I'd be pulling out slivers of wood as it splintered...

Dirko Sealant. Doesn't take much and its Cheap and yeah aluminum will break off before it fails.

I watched a couple different comparisons of construction adhesives on youtube and liquidnail was always on the bottom of the list when they were done and loctite on top !

No doubt. My experience is anecdotal, of course.... Just saying I personally had good luck with it. Project Farm wasn't around back then


For my application, it was mounting emergency vehicle equipment (sirens, light controllers, radios,etc) on the back walls of F150s and F250s which can't penetrate to the outside. That meant 3/4 ply cut into a square, then glued and screwed to the interior metalwork, so the trim/carpet could go over it, without seeing the wood.



Each ~2x3 board had about 40-50 lbs hanging off it, with zero issues... Those 100W radios are heavy.

Here's one of them mid install, hence all the loose wires still and not everything hooked up. But you can see it's mostly adhesive with a couple strategically spaced screws to aid in adhesion and act as a backup. You'll also notice due to the ribbing that it's not a solid surface to attach to, limiting the adhesion... and still, no issues...

Primer increases bond strength too. Hard to say what's best, maybe contact the panel board and see what they recommend.
