Polycrylic is composed of a combination of acrylic resin and polyurethane resin. The acrylic resin provides excellent clarity and transparency, enhancing the natural beauty of the underlying material, while the polyurethane resin adds durability and protection against scratches, stains, and moisture.
One of the distinctive characteristics of polycrylic is its ability to dry to a crystal-clear finish. This makes it ideal for projects that require a topcoat that does not alter or yellow the color of the surface. Polycrylic is also available in different sheens, including gloss, semi-gloss, and satin, allowing users to choose the level of shine that suits their preferences.
Use And Application
Polycrylic can be applied to a variety of surfaces, including wood, metal, and painted surfaces. It is commonly used for sealing and protecting furniture, cabinets, trim, doors, and other woodwork. Additionally, its versatility extends to crafts and decorative pieces, providing a protective layer that preserves the integrity of the finished project.
Applying polycrylic is a straightforward process. Before starting, ensure that the surface is clean and free from dust or debris. It is recommended to sand the surface lightly to promote better adhesion. Using a high-quality synthetic bristle brush, apply a thin, even coat of polycrylic in the direction of the wood grain. Allow it to dry fully, which usually takes around 2 hours, before applying additional coats. Multiple coats may be necessary, depending on the desired level of protection.
Once dry, polycrylic provides a durable finish that is resistant to water, household chemicals, and everyday wear and tear. It is important to note that while polycrylic offers good protection, it is not suitable for surfaces that will experience extreme weather conditions or heavy abuse.
In summary, polycrylic is a versatile and user-friendly protective finish that can be applied to various surfaces.
