Blisters in TotalBoat Wet Edge Topside Paint can develop for any of the following reasons.
- Improper surface preparation: Any surface contamination can cause the paint to be rejected in isolated spots, forming blisters in the coating.
- If a previous coating of Wet Edge, Topside Primer, or other undercoat has not cured fully, solvents may remain in the coating and can work their way to the surface, creating small blisters in the Wet Edge finish.
- Wood substrates containing a high moisture content may eventually form blisters as the moisture moves to the surface.
- Improper thinner/reducer:
- Wrong reducer was used - only use the recommended solvents when thinning TotalBoat Wet Edge.
- Too much reducer was used to thin the paint - do not exceed the maximum recommended percentage of brushing thinner or spraying thinner to thin Wet Edge.
- Submersion of the Wet Edge coating for an extended time period: Wet Edge is a topside boat paint for use above the waterline. It is not intended for continuous submersion because there is a potential for water to penetrate the top paint layer and create blisters. During cold winter months, this is especially likely to occur if any water is present under the coating.
If blisters form in your Wet Edge finish, remove the paint completely, prepare the surface carefully, then reapply Wet Edge, as directed.
