Thinner synthétique

Synthetic thinner is a blend of polar solvents designed to effectively thin synthetic paints, varnishes and resins. Versatile, it allows you to adjust the viscosity of your products according to your chosen application method and also ensures the cleaning of your tools after use. Formulated to improve flow and promote optimal film drying, this thinner is an essential ally for achieving smooth and uniform finishes.

Technical characteristics

  • High-performance blend of polar solvents
  • Thins synthetic paints, varnishes and resins
  • Reduces viscosity to suit your application method
  • Improves flow and film uniformity
  • Facilitates drying of thinned paints
  • Effective for cleaning tools and removing fresh paint stains
  • Available in 1L and 5L containers
  • Complies with REACH Regulation (EC) No. 1907/2006

Application advice

Add synthetic thinner gradually to your paint or varnish whilst mixing thoroughly until you reach the desired viscosity. The required amount varies depending on the application technique: less for roller or brush application, more for spraying. Always test on a small area first to verify compatibility and final result.

For cleaning your tools, immerse brushes, rollers and spray guns immediately after use in synthetic thinner. Rub or shake to dissolve paint residue, then rinse with soapy water. Store the product in its original packaging, tightly sealed, away from heat and ignition sources.

Warning: this product is flammable and harmful to health and the environment. Work in a well-ventilated area, wear gloves and safety glasses. Consult the safety data sheet before use and follow the guidelines for storage and waste disposal.

Pro tips

Field experience teaches us that proper dosing makes all the difference: always add thinner in small successive quantities rather than all at once. For long-term projects, keep a separate sealed container for intermediate tool cleaning, allowing you to reuse the thinner multiple times before replacing it. On site, remember to securely close the can after each use: thinner evaporates quickly and loses effectiveness if left open. For Belgian painters accustomed to strict safety standards, always keep a fire extinguisher nearby when using flammable products and ensure your workspace has adequate ventilation, particularly during winter when areas are closed off.

FAQ

What is the difference between synthetic thinner and cellulose thinner?

Synthetic thinner is specifically formulated for paints based on synthetic resins (glycerophthalic, alkyd). It is a blend of polar solvents that acts effectively on these types of paints. Cellulose thinner, on the other hand, is intended for cellulose paints and has a different composition. Using the wrong type of thinner can compromise paint adhesion and drying.

Can I use synthetic thinner to clean brushes that have been used with acrylic paint?

No, synthetic thinner is not suitable for water-based acrylic paints. For these, cleaning with soapy water is sufficient. Synthetic thinner is exclusively for solvent-based paints. Using the correct cleaning product extends the life of your tools.

How should I store synthetic thinner safely?

As synthetic thinner is highly flammable, keep it in its original tightly sealed can, away from any heat source, naked flame or spark. Store it in a cool, well-ventilated space, out of reach of children. Never transfer it to a food container and ensure the labelling remains visible to avoid confusion.

How much thinner should I add to my paint for spray gun application?

The amount of thinner to add depends on the initial viscosity of your paint and the type of spray gun used. Start by adding 5 to 10% of the paint volume, mix well and test the fluidity. Add progressively if needed. The aim is to achieve smooth flow without sagging. Always consult the paint manufacturer's recommendations for optimal proportions.

Does synthetic thinner have a shelf life?

When stored in a tightly sealed can, protected from heat and moisture, synthetic thinner generally keeps for several years. However, be sure to close the container securely after each use to prevent evaporation of volatile components, which could reduce its effectiveness.
