Recommended for you

In the Thinners product group you will find the official thinners for International paint systems: No. 1 for above-waterline paints, No. 3 for antifouling and primers, No. 7 for epoxy products, No. 9 for 2-component polyurethane products, and Nautical's NT2 special thinner.

The choice of thinner is important — the wrong thinner can break the chemical structure of the paint film, cause bumps or bubbles in the film, or prevent the paint from curing properly altogether. Each International paint series is designed to work with the thinner assigned to it: for example, a 2-component polyurethane paint requires No. 9, while an epoxy primer requires No. 7 to ensure the correct curing reaction.

Thinner is used for two main purposes: to adjust the paint application consistency for spraying or rolling, and to clean the tools — brushes, rollers and sprayers — after use. The correct dilution ratio can always be found in the technical data sheet of each paint product, and excessive thinning will weaken the protective properties of the paint film, even if application is temporarily easier.

Thinners are highly volatile solvents, so always work in a well-ventilated area or outdoors, wear protective gloves, and avoid open flames while working. Store opened cans tightly closed in a cool place, as the thinner will evaporate and lose its effectiveness over time if stored open.

Always test the effect of thinning on a small scale before starting the entire job, as excessive thinning can significantly reduce the gloss and durability of the final result. Dispose of used thinner and related waste properly according to local hazardous waste regulations — solvents should never be poured into drains or nature due to their environmental impact.

Always mark the expiration date on the thinner container if you transfer it to a smaller container while working — mixing up different thinners is a common mistake that can ruin an entire painting job due to the wrong chemistry.

Keep several types of thinner available if you are working with different paint systems at the same time — to avoid confusion, it is a good idea to clearly label each thinner bottle with which type of paint it is intended for.

Compare the price of thinners in larger packages if you are painting a larger area — the price per liter is often cheaper in larger package sizes compared to smaller ones.

Always wear protective gloves when working with thinner, as prolonged skin contact with solvents can irritate the skin.

Clearly label tools after use to prevent thinner residue from accidentally mixing with another paint job later in the season.

Keep the safety data sheet with the packaging so that the instructions for use and precautions are always at hand when needed.
