Buying Guide
What should you consider when choosing a marine paint remover?
- Substrate compatibility: wood, fiberglass, metal, and gelcoat each react differently to solvents; look for products labeled safe for marine surfaces.
- Layer count and coating types: if you know you have polyurethane, acrylic, and varnish layers, pick a formula designed to handle multiple layers.
- Chemical safety: prefer non-caustic formulas and avoid methylene chloride and NMP when possible, especially for indoor use.
- Application and dwell time: some products act quickly while others require longer set times; plan around project timelines.
- Cleanup and disposal: water-based or easy cleanup formulations simplify post-removal steps.
