RECOMMENDATIONS:
When covering existing slabs or uneven surfaces, the use of 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.

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 coated with Mer-Ko Wood Seal prior to application
3. Blend Filler and Emulsion and trowel apply to the entire area as a bondcoat and allow to dry.
4. Trowel apply a liberal coat of mastic to the previously coated area. Roll in the reinforcing fabric
followed by an additional trowel coat of mastic to “sandwich” the fabric between coats of mastic.
5. Trowel apply a final coat of the filler and emulsion blend to protect the membrane.
6. Allow a minimum of 48 hours to dry before flooding.
