National Paints Paints NC Thinner 4L, Multi-Purpose Thinning Solvent

NC Thinner is suitable for thinning most enamels, urethanes, and other coatings. It’s designed to work with both oil- and water-based coatings and can be used for interior or exterior applications depending on the coating you choose to thin.

Yes. NC Thinner is versatile and can be used to thin primers, paints, removers, and other compatible coatings. Always follow the coating manufacturer’s recommended thinning guidance and test for viscosity before full application.

Absolutely. NC Thinner is effective for cleaning brushes, equipment, and tools after painting. Rinse tools with a small amount of thinner, work out any paint, and wipe clean or rinse with fresh thinner as needed.

Key benefits include strong solvent performance, multi-purpose compatibility with enamels and urethanes, quick drying to speed up projects, ease of use when brushing, and a pleasant odor relative to some harsher solvents.

Start by adding a small amount of thinner to the coating and mix thoroughly. Increase gradually if needed, following the coating’s recommended thinning ratio. Always test viscosity on a small sample or use a viscosity cup to ensure you achieve the desired flow and leveling.

To clean up, wipe off excess thinner from tools, then rinse with a small amount of NC Thinner or another appropriate cleaning solvent. Ensure tools are clean and free of residue before storing.

Treat NC Thinner as a flammable solvent. Use in a well-ventilated area, away from heat or open flames. Wear appropriate PPE such as gloves and eye protection, and avoid skin contact. Keep away from ignition sources and store upright in its original container.
