Using floor grout on walls?

[Bertiee]

Hello,

I'm about to be tiling my toilet floor / walls and have a question. I'm tiling the floor in beige, and have some grout/adhesive in this colour. I know it's not a good idea to use the floor ahesive on the walls, however if I use some spare wall adhesive I have (which is white from the kitchen) can I then grout it using the floor grout?

Thanks

What is the toilet floor, concrete or wood? What size/type are the tiles? What adhesive & grout are you using; please don’t say fix-n-grout

On the contrary, if laying larger format tiles on the walls you should only use cement powder adhesive due to the weight.

however if I use some spare wall adhesive I have (which is white from the kitchen) can I then grout it using the floor grout?

It’s important to use the correct adhesive for the application; tub mix adhesive is not suitable for floor tiling. Floor grout can be used on walls but is generally coarser than wall grout for use with wide grout joints; walls tend to have narrow grout lines which will always look better with wall grout.

It’s not a good idea to economise on adhesive & grout & use only quality trade products not chaepo DIY stuff.

Concrete floor, 30 x 30 tiles and I haven't got the adhesive / grount yet. Wife used the tub stuff and had a large nightmare in the kitchen when it didn't set for about 10 days!

Use a cement powder adhesive on the floor & with tiles that size/weight also the walls. Standard adhesive/grout is OK for concrete floors but use flexible adhesive/grout on stud/boarded walls but it must be the correct backing if it’s going to last. If tiling over gypsum plaster/plasterboard, it must be primed when using cement based adhesive to avoid reaction between the cement & gypsum.

You shouldn’t use tub redimix on floors, it relies on evaporation rather than chemical reaction to set & is it’s not the correct adhesive.

Do yourself a favor & buy some new grout & make sure you use a quality products; for 20 quid or whatever, it’s not worth taking the risk. I use BAL but Mapei (available at B&Q), Webber, Ardex are all good; just avoid the stuff mostly sold at the DIY sheds, I think the name ends in “Blond”, “Bond” or something like that, sorry I cant remember.
