Removing the need for uncoupling mats on problematic floors. t has anti-fracture technology that absorbs lateral stress movement from the floor protecting tiles from failures. With BAL AF Max get up to 8.5m2 per bag, meaning only 4 bags are needed for a 30m2 area.
Save time, money and materials compared with a traditional uncoupling mat system: 40% lower cost, 70% time saving and 70% less material weight! No other products are needed – just mix and fix! BAL AF Max is highly flexible and elastomeric and is made with recycled rubber saved from landfill. Can be used over most common substrates, plus steel, asphalt, existing tiles, thermoplastic vinyl tiles, T&G floorboards and plywood overlays.
Key features
Assumptions for comparisons: against fixed uncoupling mat systems (mat + required adhesive), no extra floor prep (e.g., levelling), typical room layouts, and current average UK trade pricing at time of issue.

BTP very helpful in supplying a pallet of floor leveller. I needed it on the Saturday, but didn’t want it sitting on the driveway for several days. I called and they recommended ordering for Thursday to give a day’s grace in case of any delivery issues. In the event the pallet arrived on Thursday as requested. Reliable and good value
Great service and delivery! Ordered all that I needed in one go and it was delivered to the back door wrapped and protected from the snow! Pallet even made it so that the goods were dry off the ground.
Great prices and a super quick delivery turnaround. Communication was perfect aswell. So much so I’ve ordered again.
