Can you self-level over ultralight?
Warmup Insulation Boards – Ultralight
Yes, you can apply a leveling 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 leveler, first apply Warmup’s Perimeter Strip to provide for floor movements. The Ultralight boards can act as a anti-fracture membrane. Do perform that task, use the perimeter strip when using leveler in order to avoid the transfer of lateral floor movements to the floor covering above.
