ABA Multipurpose Primer & Additive is a water dispersion primer and additive designed to improve shear and tensile bond of sand/cement screeds, plasters, render mortars and tile adhesives. It is used for treating porous substrates and materials. Thus, it can be used as a primer and additive to prevents gypsum substrates from breaking off from the chemical reaction between gypsum and cement aluminates; and to improve strength of cement/sand, mortar/screed.
PACKAGING
5l
SHELF LIFE
12 months if stored under the right conditions in unopened packaging.
In general, the surface being adhered to must be clean, dry, free of dust, dirt, oil, grease and contaminating materials. New brickwood and walls should be left at least 7 days prior to rendering.
Apply with roller, brush or spray in two or more thin coats till desired thickness is achieved. Ensure that the coating is applied evenly at the recommended dry thickness.
Recommend minimum DFT is 500 – 800 microns after 2 coats. For WFT apply 500 microns +/- 100 microns per coat. Recoating interval is approx. 45 minutes from last coat. For final coat, allow UNDERTILE WATERPROOFING to cure for at least 4 hours before screeds or render can be laid.
COVERAGE
5l of UNDERTILE WATERPROOFING will cover approx. 5-7m2 for 2 coats.
