What tile adhesive is used for large format tiles?

about an hour

thats why!!!!!

you should have left the 4 and 1 overnight, 24 hrs preferably THEN
do your 2nd coat of sbr the next day, then tile........viola

1st coat seals and absorbs into the plaster, needs adequate time to set and take effect
next coat is the bonding coat, which then sits ontop of the sealing coat and adheres/fuses and stablizes..

if that's the answer my friend i most definately owe you one. i will be there in the morning applying my first coat of 1-4. to a fresh new wall. the same monday and a test tile tuesday :hurray:

 

[Aston]

just ensure you give the plaster a light sand over just to get you back to the begining/remove any thick undiluted sbr that hasnt adhered properly,,,,

anytime

ps you dont owe me anything, the idea is to help. i can understand you were a bit frustrated earlier and were a tad short with dave but that guy is one of the most respected people in the tiling industry and he has nearly 30,000 posts to prove his commitment to helping people so just try to remember that out of respect :0) what he doesnt know, isnt worth knowing

all the best steve, lets know how it pans out ;0)

well the test tiles i put up sunday were stuck solid this morning. couldn't dudge them. the walls were sanded first, then primed. 24 hours later another primer. 24 hours later a tile was stuck on. pulled half the wall off getting them off. strange how no other combination worked at all. not even slightly. thanks again. have to start getting to my jobs 3 days early.

understanding your substrates isnt too hard steve ...if the plaster/concrete etc etc is really dry, its just simply a case of balancing the suction...just get used to the difference of sealing and bonding.
higher water ratios to begin with,
adequate time to take effect & seal,
then reduce the ratios for bond

glad your sorted

 

[stevep1]

yeah great call ed. how did you know that. i must have been lucky in the past. i have primed the day before but only on an existing job to save time in the morning. all new jobs i just prime first thing then go about getting set up and set out, then if it's dry, start. all the instructions say is brush it on and when dry or tacky, get on with it. or if 2 coats needed , let first dry. no mention of 24 hours. what do you do when working away. you're gonna lose a day. clever man :smilewinkgrin:

hi steve
you dont always have to leave it 24 hrs. early morning or the eveing before is normally adequate, its just in your case/scenario, we needed to make sure there were no more problems and 24 hrs gteed that just always test the suction of your walls..you'll know the score now in the future, you wont get caught twice if in doubt, leave the 1st coat over night ...

 

[stevep1]

i most definately will

Steve, I would just like to add, none of us ever stop learning. Dave, Ed, and all the other members, imo are top of the tree. You don't get better advice anywhere, I am still learning after 43yrs and will continue to learn, until they "lay the sod over me".


But I do agree, the different primers etc. can be confusing, ie: dilution 4-1, 6-1, 3-1:mad2: it is only since cement based adhesives came in (cement & plaster are worst enemies) we need to abrade new skim, and prime accordingly. I have said in the past we now have to be chemists as well as tilers. I always ring tech. dept. if I am in doubt.
