Yes, spar varnish does come in satin. Spar varnish is one of the most popular types of varnish that is used in marine applications, as it is more resistant to UV exposure, saline moisture and changes in temperature.
Satin is a finish type, and can be achieved with most spar varnishes. To get a satin finish, the varnish should be lightly sanded when it is mostly dry. Depending on the brand of varnish, it may come pre-mixed in a satin finish, or it may need to be adjusted manually.
For example, certain brands of spar varnish may require mixing a satin finish softening agent. Regardless of the brand, it is important to follow the product instructions as each formula may require different steps for achieving a satin finish.
How do you get the finish with spar urethane?
Spar urethane is a finish often used for marine and architectural applications because it is extremely durable and long lasting. To obtain the best finish with spar urethane, it is important to prepare the surface correctly and then apply the finish properly.
First, the surface should be cleaned with a thorough degreaser. Any remaining dirt or debris should be removed with a damp rag, and then allowed to dry completely. After the surface is clean, any gouges or other defects should be filled or repaired.
Finally, the surface should be sanded with a fine grit sandpaper, such as 180 to 320. This will allow the urethane to adhere properly to the surface.
Once the surface is prepared, it is ready to be coated with the spar urethane. The urethane should be applied in light, even coats with a foam brush or fabric aerosol. Allow each coat to dry according to the manufacturer’s directions before adding a second coat.
If a glossy finish is desired, lightly sand with a 400 grit sandpaper between each coat, and then finish with a fresh coat of urethane. Once the finish is complete, the surface should be protected with a UV-resistant sealer to preserve the finish.
What is the difference between urethane and spar urethane?
The main difference between urethane and spar urethane is the type of finish they provide. Urethane is a hard, glossy finish that offers limited protection against sunlight, water, and wear and tear.
Spar urethane, on the other hand, is a soft, matte finish that offers enhanced protection against weather and wear, making it ideal for outdoor surfaces that would otherwise be susceptible to damage.
Spar urethane is also more flexible and resistant to cracking, chipping, and peeling than urethane, meaning it can stand up to harsher conditions. In terms of maintenance, both types of finishes require periodic reapplication for optimal performance.
