Thank you for posting your feedback. We're sorry to see your low star review on DAP ALEX PLUS. Because you did not provide any details regarding your experience, it is difficult to provide you with a proper reply or any product usage guidance. As is the case with all acrylic-latex (water based) sealants, volume loss will occur as the product dries, this is a normal characteristic for this type of formula. Only non-water/solvent-based sealants are capable of "low/no volume loss" performance; however, these types of sealants will require the use of solvent (mineral spirits/paint thinner) for clean-up, likewise, some of these sealants are not paintable. At your convenience, please contact DAP’s Technical Customer Service Department at 888-327-8477 so that we can obtain some additional information from you regarding your experience.
