AFM Acriglaze is a light duty topical sealer that can be used on mortar to control moisture from above, but won't provide moisture protection from below and will not hold up for very long. If you are looking to prevent moisture intrusion, a much better product would be our AFM WaterStop which is a penetrating sealer designed to chemically bond to the mortar and will stop moisture coming from above or below for a much longer time. Because it is penetrating sealer and not a topical sealer, the surface of the mortar will not be changed. If you want a tougher coating that is topical, use our AFM Mexeseal. This will block moisture from above only but will last longer than the AcriGlaze.
