Is it ok to leave SBR slurry to set before tiling...?. - TilersForums.com

Thanks Kilty55

If the floor does need levelling though, let say 10mm is it best to let the slurry go tacky prior to pouring water based slc or latex based slc, ?

On a side note what substrates is latex based slc usually used for?

 

[kilty55]

yeah if you need to level then use as advised latex

let it go off yes dont pour on slc on top if its still wet

latex slc is for flexibility
so ufh jobs and timber floors etc

Thanks kilty

ill let the slurry go hard before laying any slc.... Are we talking a few hours?

I wonder why the mapei guy says use latex rather than water based slc?

I found this thread and it seems to answer my question, however I thought I'd double check.

I had advice last week from Geoff of Plan Tec Tiling (Thanks again Geoff!) regarding an sbr slurry coat over a grano floor. The floor looked ok (level wise) but after getting my straight edge out there are a couple of areas that could do with levelling, so I'm proposing to apply weber SLC over the whole area.

is it still correct to let the slurry mix fully set before apply the SLC? It's looking like I'll be putting the slurry coat down on Friday and then looking to put the SLC either Saturday afternoon or Sunday.

i usually use weber for most things but my local CTD don't seem to stock webers sbr, so will probably end up using Bal Bond SBR.

Thanks all,
Rich

Hi rich. Glad to be of some assistance.

You will be fine later the following day to apply SLC. Yes, let slurry dry fully.
Don't forget to take photos and post them

Well, I was down tonight and went at the floor with a grinder and a diamond cupped blade to try and remove the paint.

the floor is even more uneven than i thought so the grinder has had better results on some areas than others. See pic attached. There is now definitely a need to SLC the floor before I tile it.

The grey areas are back to the grano, the red bits are where the paint is being very stubborn. Should it be okay to sbr over things as they are and then apply SLC or should I try and get more of the paint off?
