the s1 standard set white is very good

Do you use the grout Harry?

Do you use the grout Harry?

I do and get on with it well. It's somewhere in between ucp and grout 3000(like every grout)for drying. I find it dries more like ucp, as in a lot harder than 3000. Had no issues with patching to date. Unlike ucp, it's fine with ceramic

For Mapei users in the situation mentioned by Andy Allen which of their range would you use. Most upstairs bathrooms in houses have floorboards or chipboard on joists which I then overboard with a backer board , usually no more ply. I’m doing a ground floor flat bathroom and ensuitr next month - concrete slab with joists resting on top then 22mm plasterboard, then 18mm chipboard panels. I’m going to overboard with 6 my nmp. No ufh. I tend to use keraflex maxi s1 for most wall and floor applications as I get on with it well. Would there be any need to use an s2 in this situation

 

[Dumbo]

I would as long as your floor is stable and isn't bouncing or rocking , s1 will be fine . If it is rocking or bouncing sort it out as no adhesive will save it .

 

[acaciaguy]

It’s very very solid. I’ve bounced all over it it to make sure no movement at all.

What situations would you use an s2 v s1?

 

[Dumbo]

Personally I don't use s2 . My personal belief is if you need an s2 you need to improve your background prep. Bal flex was I believe originally designed for use in the subways where there is a lot of vibration from trains . Although I have just received a spec about going over low build wet underfloor heating using s2 .

thanks jctiling, that does make sense, to be honest I have never felt the need to use it. i just like to check how others are doing things. I tend to call mapei technical for any advice re: the application of their products should I feel the need. They have so many different addys most of which seem to cross over in application to each other. It can get a bit confusing. As i said i use the maxi s1 for most floors and walls and get on with it well.

its not always what your sticking to, but what is being stuck that depends on what adhesive needs to be used

Couldn't agree more

Find an adhesive that you know fits the spec and try to stick with it. Pun intended.

I’ve gone through a lot of adhesives this year, trying each one out. A few freebies. Found one I like and I’m set now.
