Sand And Cement As Adhesive?

[Italy]

This thread is one of the most interesting and insightful I've read.

I know with various additives it can be used in a lot of situations. But can anyone think of any situation where this cannot be use or tiles it can't be used with?

How is it mixed (ratios)?
Does the floor need soaking?
Do the tiles need wetting?
Setting time?
Bed thickness (minimum and maximum)?

This is alien to me. Handy info to know when a customer rings up asking if they can bed tiles into S&C.

A couple of builders I know were screeding a floor and had a lad from the pub labouring on them. They were just finishing off when they realised they were going to be short of gear, having already cleaned the mixer they told the labourer to go and do a mix by hand.
After a while they went outside to see what was taking so long only to find the labourer on his knees with his hands in the sand and cement like he was making pastery. When they asked him what he was doing he said " you told me to do a mix by hand". This IS a true story.

here in france and im sure mainland europe sand cement screed is the norm .directly after posing the screed portland cement is thrown on tge floor and tiles laid straight after .first time I seen that been done I thaught I was in the middle ages but it is very common here almost all houses are done this way.it is very messy annoying to do .but the local tilers love it .not for me .but it does work.and has worked for centuries.

When I started as an apprentice it was all sand/cement and your right it's messy, semi dry screed with a cement slurry wasn't too bad but a wet sand/cement screed with a peppering of Portland cement was dirty work. Then again it depended which tiler you were working with, some were a lot cleaner than others. They were great days, never ever short of work and you couldn't have any Tom dick or Harry stepping on your toes and taking your work. These days it is rare the Germans used to insist on monolithic fixing on floors ie aldi/Lidl, bmw hard graft but when done right you can't beat it. Lasts forever.
