Thank you for posting your feedback. We're sorry to see your low star review on DAP ALEX Painter’s Acrylic Latex Caulk. Based on your commentary regarding "cracking" during the initial drying phase, it would likely indicate that application site was subject to movement/instability prior to the product reaching full performance and/or that insufficient amount product was applied to the joint. Joints that are prone to experience significant expansion/contraction forces may require higher performance products, such as DAP DYNAFLEX 230 or DYNAFLEX ULTRA. These types of more specialized elastomeric joint sealants offer several times the amount of flexibility offered by DAP Painter’s Acrylic Latex Caulk. Because you did not provide any details regarding your experience, such as application surfaces, bead size, temperature, humidity or any information regarding your application technique, it is difficult to provide you with a more detailed response in this format. 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 about your experience and to discuss alternate product options.
