Detailed Answer – Can you Apply Thermoplastic To A Wet Surface?
No, the surface should be fully dry before application. If the surface is damp you can use a gas torch to heat and dry the surface layer enough to be able to apply the thermoplastic.
Moisture meters are cheap enough and can be used to check the moisture content of the substrate prior to application.
