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

[John the tile]

I just want to know after ive brushed it on how long should i leave it before tiling,....

Will it be ok to let it set and dry for a few hours.?

Thanks

What are you using the slurry for..?

 

[John the tile]

Concrete floor with some unremovable bitumen..

Ive just spoke to a mapei tech guy who says its best to lay some mapei 2 part latex plan before tiling. He did also say the bitumen MUST come off, (ive got alot of it off - no loose stuff left)...

He says to use mapei eco prime first, but the stuff is well expensive.......

So will the sbr slurry be ok on top of the substrate prior to the latex plan ?

Thanks

hi john,why exactly do you need to lay latexplan is the floor need ing levelled?

 

[John the tile]

No. the latex was to be used prior to tiling because of the remains of bitumen on the floor, .....

Im sure the tech guy said if you have to tile onto bitumen its best to use a latex product because of its flexibility or Ive read it on here somewhere, before tiling.

if i have to tile to bitumed residue that will not come off i use the slurry coat

i wouldnt buy latexplan

i use flexi addy too

The slurry should be enough if there is sand in it or a bit of adhesive and the floor is level.
I have a floor on next week with stubborn bitumen on it too.
I'm going to slurry it and let it harden up before tiling it.

Thanks folks.. thats exactly what ill do.

just wanted to run past you a scenario of the floor needing levelling? same as above though, with regards to the bitumen. Sbr slurry/cement.

would you let it go tacky before laying some slc down rather than letting it go hard?.

hi john,you will be fine with flexible addy instead of this latex plan onto the slurry
