Question re taking on a job....

[RDTiling]

I've done a bit of www searching on slurry coats and if what I read/watch is correct, it would appear as though the slurry coat should be applied with a stiff brush. Is this correct or can you trowel a slurry coat on with say a plasterers trowel?

Is there a certain kind of cementitious powder I should use (or someone could recommend using) for the slurry coat or can I simply use something like weber.set rapid (non flexible)?

Then it is 'simply' a matter of letting the slurry set and then tile (assuming I dont need to apply SLC) on top.

Apologies for the questions, I just want to make sure I get the preparation spot on.

Thanks,
Rich

Personally I always pour, then roller on my slurry coats. I use a flexible rapid set (Mapei), water & SBR mix 😉

Thanks Geoff. I take it the slurry coat is effectively a primer substitute? From what I've read the slurry coat only needs to be about 1mm thick so a good idea on rollering it on. It probably also applies a more even layer and takes away the need for SLC (the floor is pretty much level anyway).

Yes, instead of primer.

Thanks again Geoff. One final question for you regarding the preparation stage. Do you know roughly the proportions to mix for a 10 sqm room, particularly the water to sbr ratio so that I know how much I need to buy and quote for? What would be the rough amount of powder to add ( I know there won't be an exact amount but just so I know the rough consistency to mix to) Thanks again, Rich

First of all, slurry mixes are really supposed to be only SBR & cement mix. I have over time messed around and found it flows & rolls out much better with water mixed in with the SBR. I started out as many do with a 50/50 cement/SBR mix but found it too thick and hard to roller out.

Start with adding a litre of water to 2 litres of SBR. Then add 5kg adhesive to the mix. Once all mixed together the mix should be fairly fluid but not too runny. Adjust the mix accordingly so it's loose enough to roller out. Use more SBR if needed, not water.

Thanks Geoff. Great advice and a detailed reply as always. I think I'm armed with everything now to properly prepare this floor as it is a new one for me.

Im just waiting in confirmation on the tiles they are looking for, but I understand they would like a curved edging on the tiles to make it easier for cleaning and to protect the aqua panel that is going on the walls. Many of the committee member would've preferred the walls tiled but a majority voted for aqua panel.

I'm hoping their decision isn't going to restrict the choice of anti slip tiles they can have for the floor, as I've never used the curved edging tiles before.
