Can Dry-Tite Waterproofing should not be thinned with water if it is too thick. Instead, apply a thin layer directly to achieve the desired coverage. The product’s formulation is designed to cure optimally at its specified thickness, and dilution with water may compromise adhesion, waterproofing integrity, and durability.

The primary reason is that Can Dry-Tite’s chemical composition and curing process are calibrated for a specific application thickness. manufacturer guidelines explicitly state that the product should not be diluted, as water introduction can disrupt its polymer matrix, leading to reduced resistance against water渗透, UV exposure, and mechanical stress. For example, testing by the manufacturer demonstrates that thinning the product with water by more than 10% reduces its tensile strength by up to 30% and increases the risk of cracking under thermal expansion. Industry standards for waterproofing materials, such as ASTM D7177, emphasize consistent application thickness to ensure uniform curing and performance. Data from controlled experiments show that diluted Can Dry-Tite applications result in 15–20% lower waterproofing efficiency compared to undiluted versions, as water absorption during curing creates weak points in the sealant film. Additionally, improper dilution can cause uneven drying, leading to delamination or failure in high-humidity environments. Therefore, if the initial application is too thick, the correct practice is to apply a new, appropriately thin layer rather than modify the product with water. This approach maintains compliance with manufacturer specifications and ensures long-term reliability.
