Does expanding foam have adhesive properties and can you use it to stick skirting boards.

Can I use expanding foam to stick slate skirting boards to rendered plastered wall?
I have two 1 metre lengths of slate skirting which will be fixed either side of a fireplace opening. Being slate they are quite heavy. Will expanding foam work for this. Does it have excellent adhesion properties. If so what foam adhesive do you guys recommend.

Thanks you for your time.
Kind Regards.

It does have adhesive properties but not for this type of application. I would recommend and adhesive like "sticks like" or "grip fill".

Really there are various types of adhesive available on the market that would work in this scenario! Expanding foam however, is not an adhesive and should never be used as an adhesive! It does stick very well but fire foam for example (expanding foam variant) is used around fire door frames, expanding foam can be used to fill the gap between a UPVC window and brickwork but proper fixings can never be replaced by foam...

Try using CT1 power N grab bond your need a decent silicon gun as it’s really thick and tough polymer silicon, that’s rated for sticking granitic on vertical walls.

It’s quite expensive at £10/£12 a tube but it’s worth it’s weight in gold decent product for sticking pretty much anything together.

They also do a good range of silicon sealants in general they have another brand called CT1 sealant & adhesive comes in like 10 different colours too.

I sometimes use a foam called insta stick..its actually designed to stick 8x4 plasterboards to walls so once dry this will hold a length of skirting no problem

Don’t used expanding foam for this. If you don’t want to be able to get it off again try CT1, if you want it to stick but be able to be tapped off with a hammer & bolster then go for a grip fill.
