Surface Preparation: Surface to be water-proofed should be plumb and true to within 3mm in 3m. Rough or uneven masonry, concrete or mortar bed surfaces should be made smooth or leveled with Polymer mortar, as described above, to provide a steel float finish. Surfaces should be clean and free from dirt, grease, concrete sealers or curing compounds. Dry or dusty surfaces must be dampened and swept off. Check the plaster thoroughly and in case of cracks, treat the cracks with a flexible crack filling material. Application:

1. First treat any coves or corners. Double application of liquid is required for all coves, corners, board joints, differential material joints and changes in plane.
2. Apply a liberal coat of LATICRETE^® Hydroban approximately 4”(10cm) on each side of corner or cove, differential material joints and treated crack surfaces.
3. Now apply the first coat of LATICRETE^® Hydroban over the entire surface to be waterproofed, going back over the areas where pre-application of Hydroban is done.
4. Allow the membrane to dry for 2-3 hours.
5. When membrane is dry to touch, spread a second and top coat of LATICRETE^® Hydroban over the entire surface including the pre-treated areas.
6. When the membrane is dry to touch, tiles can be installed using LATICRETE^® Thin set adhesive fortified with latex.

Crack Suppression The LATICRETE^® Hydro Ban is designed to suppress the hairline shrinkage cracks up to 3mm in concrete and cement plaster, without the use of fabric rolls. (It has more than 400% elongation). Areas of Application
