Can you self-level over Ultralight?


Yes, you can self-level compound over Ultralight. This is particularly common when first applying our DCM-PRO membrane floor heating system and covering it with 3/8” of leveler. It can also be used directly over the boards when not using a heating system.

When using a self-leveler, first apply Warmup’s Perimeter Strip to provide for floor movements. The Ultralight boards can act as an anti-fracture membrane. To perform that task, use the perimeter strip when using the leveler in order to avoid the transfer of lateral floor movements to the floor covering above.
