There are a few reasons that TotalBoat Wet Edge Topside Paint can blister. For all circumstances, the paint should be removed, the surface prep redone with a great attention to detail, and the paint should be reapplied. Only use Wet Edge Topside Paint for its intended uses. Reasons for blistering include:
- Poor surface prep before application of the paint: surface contaminants on the substrate have rejected the paint in isolated spots.
- Off-gassing from a previous coating or substrate: if a previous coating of Wet Edge, topside primer, or other undercoat have not fully cured and released all solvents, these solvents may work their way to the surface and push little blisters into the Wet Edge topcoat. When painted, wood substrates with high moisture content may experience blistering over time as the moisture works its way to the surface.
- Improper thinner/reducer when applied: Only use the specified solvents when applying TotalBoat Wet Edge.
- Wet Edge was submerged for an extended period of time: Wet Edge paint is not designed for continuous submersion. There is a chance that water can find its way under the top layer of the paint and create a blister, especially if there is still any water present under the coating during cold winter months.
