Composeal Liquid Black Gold is a thin, load bearing liquid applied membrane. Formulated using a single component modified latex with excellent elongation properties and high strength. The membrane is installed in a semi-fluid state and can be applied to practically any form or irregular shape (i.e. base flashings, protrusions, walls, etc.). Composeal Liquid Black Gold will inhibit transferring of shrinkage and non-structural cracks caused by horizontal movement, when tile and stone finishes are used.
Surface Preparation:
All surfaces must be between 40º F (4º C) to 95º F (35º C) and structurally sound (deflection not to exceed 1/360 of the span), dry, clean and free from oil, grease, wax, paint, old adhesives, sealers and curing compounds. Any contaminates which inhibit proper bond must be removed. Substrate preparation should be completed following ANSI A108 AN-2
General Requirements:
for Sub-surfaces.” All substrates should be plumb and true, surface deviation should not exceed 1/4” in 10’. Patching, leveling or areas requiring a mortar bed should be prepared using underlayments. Movement (expansion) joints should be provided to comply with TCNA method EJ 171. If product has separated, product should be mixed with a slow mixing drill, not incorporating air. Some separation may occur upon standing, which has no reflection upon the quality of the product.
Preparation:
Joints and Cracks Pre fill all substrate cracks, cold and control joints with modified thin set, 100% Silicon or polyurethane caulking.
