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 (See ROCKCOTE Technical
Specification on Efflorescence and its removal).
