This is one of them - although they are very sharp, they are actually plastic. With great difficulty and care I’ve managed to dig them all out - fortunately the tilers left us some grout! I saw the lad kicking out the levellers with his boots so guess that’s why. He also chipped a tile edge which we’ve had replaced. Didn’t notice these boy bits until later!
hi Dave
yes, I sorted it myself. Managed to dig out all the bits, fortunately tilers left us some grout so will have to patch it up. We have had so many tiling problems, couldn’t face them returning! thank you for for interest
