Thank you for posting your feedback. We are sorry to see your low star review on DAP Drydex Spackling Paste. DAP DryDex is formulated to apply as a thick/heavy bodied paste. If the product should thicken or is excessively dry (which typically indicates that the product is aged or nearing/beyond its 12 month shelf life), providing that the material is still pliable, a small volume of water may be added to the product and mixed thoroughly until the original smooth/even textured consistency is restored. Should you have any additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477. If you would like to verify the age of the material, when calling in please be sure to have the package available, as we will need the production code printed on the package in order to determine the date of manufacture.
