Went and bought some limestone slabs (60x30cm) today to lay as a hearth in front of the fireplace. The seller suggested that I could just as well glue them with PL400 instead of setting them with normal natural stone adhesive.
Never tried it, what surface are you going to attach the tiles to?? I have completely stopped using pl and have switched entirely to Novatech Tec7 when it comes to adhesive. Incredibly strong!! The tiles are likely to stay put
