Varnish application is an important process for protecting wooden surfaces and increasing their aesthetic appearance. When applied correctly, it prolongs the life of wood and increases its resistance to external factors. However, there are some important points to be considered during varnish application. Here are some suggestions that will help you achieve success in varnish application:
Surface Preparation: The surface must be clean, dry and smooth before varnish application. Residues such as dust, dirt and oil on the surface prevent the varnish layer from adhering properly. In addition, scratches and roughness on the surface become more noticeable when covered with varnish. It is therefore important to smooth the surface thoroughly using sandpaper.
Choosing the Right Varnish: Varnish types differ for indoor and outdoor applications. For outdoor woods, UV-protected and water-resistant varnishes should be preferred. For indoors, the choice can be made by prioritizing aesthetics. It will also be useful to choose varnish according to the type of surface to be applied (for example, soft or hard wood).
Application Technique: Varnish can be applied with a brush or roller. Brush is ideal for corners and places requiring detailed workmanship. The roller provides faster and easier application on large surfaces. When applying the varnish, always move parallel to the grain direction of the wood. This ensures a smoother coating.
Number of Coats and Drying Time: Varnish application usually requires more than one coat. A new coat should not be applied until each coat is completely dry. The recommended drying time between each coat should be observed and the surface should be sanded and prepared for the next coat.
Weather Conditions: Weather conditions should also be taken into consideration when applying varnish. High humidity or extreme temperatures may affect the drying time of the varnish. Ideal conditions are mild weather and low humidity.
Final Controls: After all coats have been applied and the surface is completely dry, final checks should be made. Make sure that the varnish layer is even and uniform everywhere. If there are missing or thickly applied areas, these parts should be corrected.
Varnish application requires care and attention. By following these steps, you can protect your wooden surfaces and extend their lifespan. It may also be worth seeking professional help to get an expert opinion and choose the right products.
