I got a call last week from an LVT job I completed just under 2 years ago, customer said a tile was lifting. When I got there and had a look, it turns out the builders screed had blown. My compound was still bonded to the tile and aggregates. Where it had lifted away you could see the builder hadn't primed it, it was dusty! He must have chucked his screed down without even brushing up. The floor was approx 20m2 and most of it was ply apart from a few metres, I used 700 over the lot of it. Luckily, I have the materials already so hopefully won't cost me apart from a few hours labour. Going to have to lift most of it and put down 600 first, then next day Fasttrack 30 and fit...and I'll Hoover up before I prime!
do ya mean the builders layer of smoothing compound or his actual sand cement slab? never heard of a sand/cement slab to do that must of been pretty shoddy workmanship from the builder for that to happen!
That reminds me of last week when I drove 1 hour to latex a kitchen for a builder. He done the first coat of latex to lose the old ceramic adhesive with some topps tiles latex and no primer. It was bright white and hollow as ****. Me, Matty and him had all 15 m2 lifted 20mins later. He was gutted....kept going on about how many bags he'd put in there and how his labourer must of put too much water in blah blah blah
Yep heard that before on one of my jobs. Lets blame the labourer. I could tell by his face it was him.
It was a small concrete area that was built up on top of the main slab to match the height of the timber sub floor. A bit odd really.
