utility room tiling - flexible adhesive?

[DrGonzo]

Plan to tile the floor in a utility room where there is also a washing machine.
Should I be using flexible adhesive for this due to the vibrations from the washing machine ?

Only if you're tiling onto wood.

wooden floorboards covered with exterior grade plywood.

Then you want to be using Bal Single part flexible adhesive http://www.trades-direct.co.uk/modules/shop/view.asp?Prodcode=2025-104
I won't use anything else on wood floors. You'll get about 4.5 sq metres to a 20kg bag. Can work out expensive, but it's necessary.

Out of interest, why is it that the normal adhesive won't work or is it just that this stuff lasts longer ?

I've had mixed success with other brands (Granfix for one) - never had a problem with BAL flexible gear. Of course if you want to use some cheap stuff that's your business.

No, that's fine - I'll use BAL but was just wondering why.
Is it because the floorboards can move over time ?

Also if a 20kg bag covers 4m2 how much flex grout should I get?
...just a 10kg bag?

 

[gcol]

No it's cause the floorboards move all the time.
It depends how big your tiles are and what grout space you leave as to how much grout you use. Working on 13" x 13" tiles and leaving a 5mm grout joint, you'd be looking at about 7 square metres per 5kg bag (if my memory serves me correctly).
