WP-47 Fiberlath is required over sloped and built up areas or where maximum reinforcement is required. Place WP-47 over the base and roll into place, cutting to fit with two inch overlaps. Trowel the slurry coat directly into the WP-47. An additional slurry coat may be required to hide fabric when WP-47 is used. As an option, It may be laminated to surface with WP-90 Waterproofing Resin, at a rate of 75 to 100 square feet per gallon.
