RECOMMENDATIONS:
When covering existing slabs or uneven surfaces, the use of Mer-Krete Underlayment is recommended as a smoothing coat or to provide required pitch.
Wood subsurfaces used as traffic areas require a minimum 1" sand/cement mud bed pre-float with wire reinforcement to provide a rigid substrate to support traffic per TCA guidelines.
The use of a latex modified mortar (ANSI A-118.4) or acrylic admix such as Mer-Krete 150 Acrylic Latex is highly recommended for setting all ceramic and stone tiles to ensure compatibility.
Surfaces to be coated must be clean and free of contaminants. Sealers, curing compounds and all protrusions must be removed prior to application.

INSTALLATION:
Work should be performed only by an applicator trained and familiar with these products, and in strict accordance with manufacturer application specifications, abbreviated below:
1. Prepare and clean surface to be waterproofed.
2. For installations over non-traffic bearing wood surfaces, the entire area to receive membrane must be primed prior to the application of the membrane.
3. Trowel apply a liberal coat of mastic to the area to be waterproofed. Roll in the reinforcing fabric followed by an additional trowel coat of mastic to “sandwich” the fabric between coats of mastic.
4. Ensure the reinforcing fabric is overlapped a minimum of 2" and turned up at all wall to deck junctures a minimum of 3".
5. When positive waterproofing is required, apply a final coat of mastic after the membrane has dried to the touch to ensure that any pinholes are completely filled.
6. Allow a minimum of 48 hours to dry before flooding.
