To apply damp seal, ensure the surface isn't dripping wet, clean away any mold, and then apply a thick coat over and around the damp area with a brush.
Here's a breakdown of the process, based on the available information:
-
Surface Preparation:
- Ensure the surface is not dripping wet.
- If mold is present, clean it away with a mold killer product prior to application. This is crucial to prevent further mold growth beneath the damp seal.
-
Application:
- Using a brush, apply a nice, thick coat of the damp seal paint.
- Be sure to cover the affected area and extend the application slightly beyond the visible damp to ensure a complete seal.
