Apply Protective Clear Coat

What happens here

Once the stain is completely dry, the final step involves applying a protective clear coat. The video features Minwax Helmsman Indoor/Outdoor Spar Urethane (Clear Semi-Gloss), which is chosen for its superior protection against sunlight, rain, moisture, and temperature fluctuations, making it an excellent choice for a window located in a high-moisture area like behind a sink. A 2-inch synthetic bristle throw-away brush is recommended for application to ensure a smooth finish and easy cleanup. The clear coat is applied in very light, even coats. To coat the inside edges of the window, open the window slightly during application and then close it back up just enough so the coated surfaces do not touch while drying. A fan is utilized to expedite the drying process between coats, especially beneficial in cooler conditions. Two coats are typically applied for enhanced durability and protection.
