Buying Guide: Topside Paint Purchase Considerations
What surface am I painting?
Choose a product formulated for your surface material (fiberglass, wood, or metal). Some formulas are specifically noted as better for fiberglass or wood, while others are versatile across surfaces above water.
Do I need gloss or semi-gloss?
Gloss levels affect appearance and ease of cleaning. High-gloss finishes show more surface imperfections but are easier to wipe down. Semi-gloss or satin hides minor flaws but may require more frequent cleaning to maintain shine.
Oil-based vs water-based?
Oil-based topsides often offer superior leveling and durability but require good ventilation and longer cleanup with solvents. Water-based options are easier to clean and typically have lower odor but may require more coats for durability in harsh marine conditions.
Application method and workspace
Many topsides support brush, roller, or spray applications. If spraying, ensure you have proper ventilation, a suitable spray tip, and a dust-free workspace. For smaller boats, brushing or rolling can be faster with minimal setup.
Primer compatibility
Using a compatible primer improves adhesion and finish longevity. In particular, TotalBoat primers pair with their topcoats for a unified system and easier repair work.
Durability and maintenance
Look for chemical resistance and scratch resistance when choosing a topside paint for busy or high-traffic decks. A high-gloss finish typically offers easier cleaning and better UV resistance for color retention.
Safety and environmental considerations
Follow safety guidelines for solvents and ventilation. Check for chromate-free and lead-free formulations where noted, and dispose of solvents according to local regulations.
