Key features
- Zero VOC – 0 g/l (US regulatory), solvent free and water free, EMICODE EC1 PLUS.
- Moisture control – with the WAKOL B5 All-In-One trowel, tongue and groove flooring can go on slabs up to 12 lbs per 1,000 sq ft per 24 hours (ASTM F1869) or 90% RH (ASTM F2170).
- Sound reduction – STC 61 / IIC 62 on a 6" slab with a ceiling.

Approved subfloors
Concrete, gypsum, OSB, plywood, particle board, wood planks, terrazzo and ceramic tile, above, on or below grade. It can go directly over WAKOL PU 280.
With a standard trowel, concrete must not exceed 3 lbs or 80% RH. Above 80% RH, Wakol requires PU 280 first, which takes the system up to 100% RH. Not for subfloors with excessive moisture or hydrostatic pressure.
