Buying Guide
- Surface compatibility: Most products target fiberglass, wood, and metal above the waterline. Confirm your substrate before selecting a paint or sealer.
- Finish and appearance: Semi-gloss finishes offer a balance of gloss and durability, while flat or clear sealers provide a more natural look and different protection profiles.
- Drying time and recoat windows: Quick-drying products speed up projects but check recoat intervals to achieve a smooth, even layer.
- Water-based vs. oil-based: Water-based options generally have lower VOCs and easier cleanup, but oil-based formulas can offer greater durability and leveling on rough surfaces.
- Coverage and project size: Estimate square footage to determine the quantity needed. Some paints include thinner for on-site adjustment, which can affect coverage.
- UV and moisture protection: Look for UV-stable coatings and moisture resistance for docks, piers, and boat decks prone to sun and spray exposure.
- Safety and environmental impact: Consider products labeled ultra-low VOC and aquatic-life-safe where applicable, especially for projects near water.
- Application method: Brush, roll, or spray compatibility varies by product. Follow manufacturer instructions for best results and temperature guidance.
- Maintenance and touch-ups: Choose coatings with easy maintenance and good touch-up performance to extend surface life with minimal effort.
