not require special disposal. KERDI is 8-mil thick and has a water vapor permeance of 0.90 perms, when tested according to ASTM E96,
using Procedure E at 90% relative humidity. KERDI-DS is 20-mil thick and features additives to produce a water vapor permeance of
KERDI is suitable for wall and floor surfaces where protection against the penetration of moisture or other harmful substances is
necessary. Applications include showers, intermittent use steam showers, tub surrounds, and areas surrounding swimming pools.
