This one’s Bostik FIX A760 TECH, a posh tacky glue for all your soft floor coverings — vinyl, carpet tiles, and those bendy soft tiles that never stay still. It sticks firmly but stays a bit tacky, so you can lift or replace tiles later without needing a chisel and a prayer. Works on both absorbent and non-absorbent floors, so whatever you’re standing on, it’s got you covered. On absorbent floors it gets sticky in about 45–60 minutes, but on shiny ones you might be waiting 2 to 2.5 hours. Coverage depends on the floor type, around 60–120 g/m². Use a 12 mm anti-drop roller (fancy way of saying "a roller that doesn’t fling glue in your face"), and go for: 100–120 g/m² on absorbent floors, or 60–80 g/m² on wood and non-absorbent ones.
