This Sea-Line epoxy primer thinner is a carefully balanced blend of solvents designed to maintain the optimal performance of epoxy primer coatings. Using the correct manufacturer-recommended thinner not only makes application easier, but also ensures the chemical bonds in the epoxy coating form properly. If a universal or incorrect thinner is used, the structure of the coating can be altered, leading to poor adhesion, wrong viscosity, and defects in the final layer.
The Sea-Line thinner provides the precise parameters needed – pot life, drying time, flow – so that the primer applies and cures in the best possible way. The proper viscosity helps the primer level out evenly without sagging or producing an "orange peel" texture. This thinner is also suitable for cleaning tools (brushes, rollers, spray equipment) after working with epoxy primers, preventing any leftover material from hardening on your equipment.
- 250 ml: A small can, perfect for minor projects or when only a small batch of primer needs thinning. Convenient for one-time use with minimal waste.
- 1 L: A standard bottle for routine use, sufficient for painting a single boat or several medium-sized projects. Meets the needs of hobbyists and professionals for periodic work.
- 5 L: A large container intended for intensive use or professional workshops. Ideal if you have multiple boats to treat or a large project requiring a significant amount of primer.
- Usage: Mix your epoxy primer with this thinner according to the guidelines in the primer’s technical datasheet (the percentage varies by application method: e.g., ~5–25% for brush/roller, up to 50% for spray in the case of Lightprimer). Stir thoroughly and apply at a suitable temperature (around 15–25°C).
- Recommendations: Never substitute the dedicated thinner with a generic one – doing so can lead to poor adhesion or coating flaws. Using the proper thinner preserves the anticorrosive properties of the primers and ensures long-lasting hull protection. After application and before the primer fully cures, clean your tools with this thinner to keep them ready for next use.
