This 5-liter polyurethane thinner is the essential technical thinner for ensuring optimal performance of polyurethane paints, enamels, and coatings. Its professional formulation has been specifically developed to adjust the viscosity of two-component products, facilitating smooth and even application with brushes, rollers, or spray guns. In addition to its primary function as a thinner, this high-performance liquid also acts as a powerful cleaning agent, ideal for dissolving fresh paint residue and keeping tools in perfect condition after use.

With a large 5-liter container, this solvent is designed for professionals and individuals undertaking large-scale painting projects who need a reliable product that won't affect the gloss, drying time, or final hardness of the coating. Its use ensures perfect adhesion between layers and prevents common defects such as brush marks, bubbles, or wrinkles on the painted surface.

Characteristics of Polyurethane Solvent 5 L

• Capacity: 5 liter container, ideal format for construction, renovations and continuous painting work.


• Compatibility: Specifically designed for one and two component polyurethane paint and varnish systems.


• Dissolving power: High capacity to regulate viscosity without losing the covering power or mechanical properties of the enamel.


• Effective cleaning: Excellent for deep cleaning brushes, rollers, airbrushes and trays with polyurethane paint residue.


• Balanced drying: Contributes to controlled evaporation that promotes leveling and a smooth finish of the paint film.

Frequently Asked Questions

What type of paints should this solvent be used for?

This product is formulated exclusively for thinning paints, varnishes, primers, and polyurethane coatings. It is not recommended for use with water-based plastic paints or conventional synthetic enamels.

Can it be used to clean tools with dried paint?

It is most effective on fresh paint. However, for tools with embedded residue, prolonged immersion in this solvent helps to soften and loosen the hardened polyurethane resin.

What proportion of solvent should I add to the paint?

The exact amount depends on the chosen application method and the paint manufacturer's specifications. Generally, between 5% and 15% is added for brush or roller application, and a slightly higher percentage for spray application.

Does it require any safety measures during its application?

As it is an organic solvent, it is recommended to work in well-ventilated areas, using protective gloves, safety glasses and a suitable mask for organic vapors.
