APPLICATION PROCEDURE
Surface preparation
The supports must be compact, seasoned and steady, without cracks, oils, paints or detachable parts. Check to see if the bricks are securely attached and do not have parts that can detach. If there are such parts, remove them and repair surface with mortar. Walls that are coated with grout must be scraped in order to verify if the surface under it, was painted with old and badly attached paints, or if there are detachable parts. Powdered surfaces should be treated with MEGAGRUND Liquid primer. Superficial cracks can be caulked with TB 300, while deep structural cracks should be treated in a way to eliminate the causes and the possibility of repetition. If the surface is not flat or straight, it should be flattened or made straight using MEGAGRUND.
