Installation Requirements

1. Trim the water proofing membrane/crack isolation membrane to the size of the floor being covered. Prepare the floor making sure dust & debris are removed from the surface. After the surface area is clean, use modified/multi-purpose thin set using a 1/4” x 1/4” (6mm x 6mm) square toothed trowel.
2. Apply the Composeal Grey PE sheet membrane to the ground in a precise and edge-to-edge direction and smooth it towards the edges. Avoid air inclusions and glue residues!
3. (only needed for waterproofing) After installing the sealing membrane, apply the seam tape and corners and continue according to the installation instructions of sealing products. Please use 5” PE seam tape on joints and all corners. Use 5” PE seam tape or you can cut 5” strips to make your own seam tape, seam is applied using thin set (Seam tape is non adhesive).
4. If the floor is to be sealed as well, the joints must be covered with a sealing tape and waterproofing material. Liquid membrane can be used under the membrane to the floor. Mix waterproofing material and apply it onto the water proofing membrane/crack isolation membrane with a suitable notched trowel.
