WATERPROOFING – Rain may negatively impact both indoor and outdoor waterproofing projects. It is one of the worst conditions for waterproofing, as the application requires dry conditions in order to dry properly.
You must wait for few days after cleaning. Because water-resistant coatings are susceptible to moisture, you must wait a few days after cleaning your deck for the wood or concrete to dry completely before applying the coating.
Observe the weather forecast to ensure that it will not rain several days after the application has been submitted. If precipitation occurs, it may affect the coating.
