Rockcote Anti Efflorescent Primer provides an effective barrier coat against efflorescence. It has excellent adhesion and will provide a slip resistant finish for easy application of subsequent trowel applied coatings. Rockcote Anti Efflorescent Primer should be used for the priming of all site-mixed renders and mortar jointed brick/block walls. Allow 28 days for site-mixed renders to cure before applying Rockcote Anti Efflorescent primer.
