    Does anyone ever get adhesive shrinking?

    Let’s say you tile half a wall, go back the next day to tile the rest and once the second lot of tiles has set, it’s shrunk back ever so slightly.

    I’m not talking about a thick bed of adhesive either. Or too much water in the mix.

    I’m wondering if levelling clips would help to prevent this.

    Just thinking out loud. No major issue with shrinkage, I just wondered if anyone else has noticed it much.

    Yep, I've had it a few times in years gone by. A tiny lip the next day that you know wasn't there the day before.
    Yes, clips most definitely stop this

    Cheers for the reply...

    Just ordered 5000 clips. I have a friend who’s a Tiler and he has a birthday coming up ;) ;)

    On a serious note. You’d think something like this shouldn’t happen in this day and age with modern adhesives.

    With consistent troweling and bed depth it would be minimal.
    Bedding up different depths = different shrinkage.
    Spot fixing = major shrinkage differences.

    This is one of the reasons why clips exist, not to turn amateurs in to pros, like the uneducated would have you believe.

    Talking of modern adhesives, Bio can suffer shrinkage more than you would want to believe.

    Everything is becoming over engineered, and too finely balanced on a knifes edge.

    I’ve used a lot of Biogel this year. It does shrink a little, to an extent anyway. We are talking a fraction of a Millimetre. Only really noticeable on rectified tiles.

    I hadn’t actually considered that about clips until recently so thanks for confirming it.

    .........confirming that I’m uneducated :tearsofjoy:

    This is something i've been trying to get my head round recently, but only because of a differnt effect. Crazing.

    People have been using all makes 150x75, 200x100 and 300x100 of class BIII (absorbtion >10%) in kitchens and bathrooms. They start to craze immediately after install. Of all the cases i've looked into, a cement based adheve has been used and around 90% of those have been rapidset or semi rapid. But of course you speak to the manufacturers and the tell you the adhesive can't be to blame (tilemaster, bal, weber and palace) . Can't do much but take their word for it but i'm not convinced. Never seen it happen with readymixed

    I tried Tilemaster Lightweight last week. That takes 8 to 9 litres of water per 15kg of powder. I found it shrunk quite a lot. Tried a few adhesives recently. I don’t think there is a perfect one.

    I’m still keen to try Isomat gear.

    I think with some of the newer adhesives that have recycled materials added to it and using more water would create shrinkage if some sorts
