Hi All.
Got to admit, having to use S&C to form a wet room floor is a first for me. I Got a call out of the blue from a builder who I have never come across ,quite a few other things setting off alarm bells....... Painter already in an adjoining room,waste pipes at a jaunty angle,promises of we will do this,we will do that.......
but what is the minimum thickness of sand and cement required and how long would this take to dry? Just what to be sure of my facts when I ring him up.

You can take screed down to 30mm if needed but usually 50mm on concrete base with a few fibres thrown in for good measure and a slurry with sbr onto the base will insure a good grip.

I think the falls to the drain is 20mm in a linear metre if memory serves me right....

Which is not too far off being achievable. But the drying times?

The builder reckons 2-3 days!!!! lol

He can wish.....BS state about a day per 1mm or at least give it couple of weeks....or 4.

I think min for sand and cement screed is 40mm/50mm but that could be reduced to suit falls with modern technology.

I think a tanking system before the screed might be a way to go.

I will wait for Ajax to respond, he has never let me down with his advice, so I will bow to Alan's experience.

Good luck.

That's the formula I would use on a concrete,but wondered if S&C was different.

Why don't you use a fast -track screed then you will be able to tile on to it within hours if need be ,deffo Tanking deffo SBR/cement slurry for bonding !, i think the minimum you can screed down to with traditional screed is 25mm under BS.......

Looks like I was a bit slow with my answer, but 1:60/ 1:80 for falls imo as stated 1mm per day up to 40mm then 2 days per mm after that. It's my age, by the time I have typed, a dozen people have replied.:oops:

Would tanking first before the S&C screed is laid, inhibit the drying times of the screed?

Again I think Ajax is the man for this but imo the sand and cement screed will cure, residual moisture content traveling to the surface, rather than going down, I just thought a tanking membrane would be a good thing for a wet room.

I'm sure Alan will put me right.:thumbsup:

Hi Phil
The tanking is a given,just the positioning was in question.:thumbsup:
