Unlocking the Science of Resistance: The Power of Polyurethane Resin
The key to the high performance of polyurethane paints lies in their chemical composition, more specifically in the polyurethane resin . When drying, this resin goes through a process called curing , forming a plastic film with unique characteristics:
High Mechanical Resistance: Imagine an industrial floor supporting the constant back and forth of forklifts, the impact of heavy objects and daily abrasion. Polyurethane paint, with its high mechanical resistance, ensures that the surface remains intact, without cracks, wear or loss of color.
Impressive Flexibility: Unlike other paints that crack with the natural movement of materials, polyurethane paint follows the expansion and contraction of surfaces without compromising the integrity of the finish. This flexibility is especially important in external areas, subject to temperature variations.
Impenetrable Barrier: The film formed by polyurethane resin acts as a shield against the action of water, humidity, oils, grease and even some chemicals. This feature prevents the infiltration of agents that cause stains, mold, corrosion and deterioration, ensuring the longevity of the surface.
Polyurethane Paint: The Smart Choice for Demanding Projects
Polyurethane paints stand out as the ideal solution for a variety of projects, exceeding expectations in terms of resistance, durability and aesthetics.
See why polyurethane paint is the smart choice:

Mastering the Art of Application: Step by Step for a Flawless Finish
Correct application of polyurethane paint is the secret to an impeccable and long-lasting finish. Following the manufacturer's instructions, preparing the surface properly and using the correct tools are crucial steps to the success of your project.
Follow the detailed step-by-step instructions for a perfect application:
1. Surface Preparation: The Foundation for a Flawless Finish
Cleaning: Thoroughly remove dust, cobwebs, grease, mold, mildew and any type of contaminant from the surface. Use a damp cloth with water and neutral detergent, rubbing well to remove impurities. Rinse with clean water and wait for complete drying.
Removing Old Paint: If the surface is already painted with peeling paint, use a spatula to remove the loose parts. Then, sand the entire surface to remove imperfections and ensure the new paint adheres.
Sanding: Use sandpaper of different grain sizes (coarse, medium and fine) to level the surface, remove imperfections and create micro grooves that facilitate paint adhesion. Always sand in the direction of the wood grain (if applicable) and remove dust with a damp cloth after sanding.
Application of Primer: The primer is a product that evens out paint absorption, ensuring a more uniform and long-lasting finish. Choose a specific primer base for the type of surface (wood, metal, masonry, etc.) and apply it with a lambswool roller or brush, following the manufacturer's instructions. Wait for the primer to dry completely before proceeding to the next step.
2. Paint Preparation: Dilution and Homogenization
Dilution: Polyurethane paint generally needs to be diluted for application with a brush, roller or spray gun. Use the thinner recommended by the manufacturer and follow the instructions on the packaging regarding the dilution proportion. Inadequate dilution can compromise the quality of the finish and the durability of the paint.
Homogenization: Before and during application, mix the paint well with a paint mixer or a wooden ruler to ensure pigment homogenization and color uniformity.
3. Paint Application: Techniques for a Professional Result
Choice of Equipment: The choice of painting equipment depends on the surface to be painted, the type of polyurethane paint and the size of the project.
Brush: Ideal for small areas, corners, details and finishes. Use a soft-bristled brush and apply the paint in thin, even layers.
Foam Roller: Suitable for smooth and extensive surfaces, such as walls and ceilings. Use a high-density foam roller to avoid bubbles and brush marks.
Paint Gun: Provides a professional finish, with uniform paint spraying. It requires practice and specific care when diluting the paint and adjusting the gun.
Application of the First Coat: Apply the first coat evenly, in the direction of the wood grain (if applicable). Avoid applying excess paint to avoid creating runs and bubbles. Wait for the manufacturer's recommended drying time before proceeding to the next step.
Sanding Between Coats: For a super smooth finish, lightly sand the surface with fine sandpaper between applying each coat. This step removes imperfections, ensures better adhesion of the next layer and provides an impeccable final result.
Application of Remaining Coats: Apply 2 to 3 thin coats of paint, respecting the drying time between each coat. The number of coats varies depending on the type of paint, color, surface and desired finish.
Tips for a Professional Finish:
Suitable Environment: Work in a well-ventilated environment, with a mild temperature (between 10°C and 35°C) and relative humidity below 85%. Extreme weather conditions can affect the drying and finishing of the paint.
Protection: Use personal protective equipment (PPE) throughout the painting process, such as mask, gloves and protective glasses.
Organization: Protect the work environment with a tarp or cardboard to avoid paint spills. Use masking tape to delimit areas that will not be painted.
Cleaning: Clean brushes, rollers and guns with thinner immediately after use. Dry paint can damage equipment.
