Benefits of PU Clear Varnish

Enhanced Durability: PU clear varnish forms a protective layer on surfaces, safeguarding them from scratches, stains, and everyday wear and tear. It increases the lifespan of your furniture, floors, or other surfaces, ensuring they remain in pristine condition for longer periods.

Visual Appeal: The transparent nature of PU clear varnish allows the natural beauty of the underlying material to shine through. It enhances the aesthetics of wooden surfaces, bringing out the rich grains and textures while providing a glossy or satin finish, depending on your preference.

UV Protection: PU clear varnish contains additives that offer protection against harmful ultraviolet (UV) rays. This feature is especially beneficial for outdoor furniture and wooden surfaces exposed to sunlight, preventing color fading and deterioration caused by sun exposure.

Easy Application: PU clear varnish is easy to apply, whether you choose a brush, roller, or spray method. It dries relatively quickly, allowing for efficient application and minimizing downtime.

Application of PU Clear Varnish

Before applying PU clear varnish, it's important to properly prepare the surface. Here's a step-by-step guide to ensure optimal results:

Step 1: Surface Preparation

Ensure the surface is clean, dry, and free from dust or debris.

Sand the surface lightly to create a smooth and even base for varnish application.

Remove any existing coatings or finishes using suitable solvents or sanding techniques.

Step 2: Applying the Varnish

Stir the PU clear varnish thoroughly to ensure an even consistency.

Apply a thin and even coat of varnish using a brush, roller, or spray method. Follow the grain of the wood for a smoother finish.

Allow the first coat to dry completely before applying additional coats. Two to three coats are generally recommended for optimal protection and appearance.

Sand lightly between coats to remove any imperfections and create a smooth surface.

After the final coat, allow the varnish to cure as per the manufacturer's instructions.

Step 3: Maintenance

To maintain the longevity of the varnish, avoid exposing the surface to excessive moisture or extreme temperature changes.

Clean the surface regularly with a mild, non-abrasive cleaner to remove dirt and stains. Avoid using harsh chemicals or abrasive materials that may damage the varnish.
