Use of expanding foam glue on green plasterboard? - Tile Advice

Will Blackburn · Jan 16, 2017

Hi.

I am using a green plasterboard for my bathroom walls to tile onto.

I used dot and dab mix in my last house but what I want to know is if it is ok to use expanding foam type glue?

I have seen it done on plasterboard but not sure if its strong enough for 1) tiling onto or 2) suitable for green plastboard?

Any ideas?

Thanks
Will

Stick with dry wall adhesive, expanding foam does just that and may push the boards away from the wall.

Just had spin through the reviews, I'll stick with trusted dry wall adhesive, they do state for plasterboard but just a matter of choice for convenience.

That's what I am thinking.

Only reason thinking this as I have a few tins.

I know it says plasterboard but that could just be standard drywall.

Banging a load of tiles onto it might push it over the limit??

The only thing to do is contact the company and speak to the technical people.

I have just done the toilets of a shop after it was boarded out using this stuff, I was not keen to tile on it if I'm honest, bit the builder gave it the big bs and well I ended up sticking to it as it's on a regular contractt and didnt want to end up losing the work, the boarder is usually pretty good, but the areas where this stuff was used are all over the place, so I'm guessing it's not easy to use, but did feel sturdy enough, only time will tell tho

in terms of grab strength it is fine. It is used to stick floor boards to joists as well so has a high flexural strength. Don't know what the shear strength would be which is what you need for tiling but a call to the manufacturers would tell you that if the data sheet does not. I am intending to use a similar material to stick board to my kitchen walls as cannot afford the space to dot and dab with dry wall addy.

Note green plasterboard is only slightly moisture resistant and I would still recommend tanking over it if used in wet (eg shower) area.

Only good (i use that term loosely) on new block work and if its plumb and flat .
On uneven old walls etc you may as well try sticking it on with blue tac .
Its Removed a bag of Removed and thats why it does not sell big in the art of plastering

a bit harsh wilder but I take your point. It is good for sticking down chipboard to joists though
