Expanding Foam

[Taz8130]

Just finished a small splash-back on D&D plasterboard over brickwork at a local stables. Board was flexing pretty bad over approx linear 1 mtr so instead of ripping it off, mate who's a plasterer advised me to use expanding foam. Did it yesterday to secure. Came back today and it was rock solid. Anyone used this method before?

Very True

This stuff is excellent as a fixing foam we used it all the time fitting windows I would not trust it on plasterboard use dri wall addy grabs much better.

Everbuild products have designed a new product for use instead of dot and dab on decent walls. Saw a guy using it on a site looks the business you can then start tiling on it 1hr later.

Expanding foam is hand to have in the back of the van has got me out of lot of trouble over the years.

What I was advised to do was drill a number of holes to insert tube on exp. foam can and spray foam into the void. The additional holes allow for excess foam to expand without causing p/board to "belly". On a small area it works great.

Love Expanding faom.

I saw a plumber bed a toilet pan on some once, came back next day and it had lifted 2" of the floor mg_smile:

Have seen that and even seen them just skim round the exposed new gap

 

[chrisroe]

yes it does work but only small areas

Just to clarify. The expanding foam method I am talking about is where the plasterboard has already been put to the wall, either recently or after a long period of time, and prior to tiling you find that an area has too much give in it.
