Topcoat Tips and Best Practices

First things first, let's talk top coat. I prefer to use a water-based polyurethane for its ease of use, fast dry time, and ability to maintain clarity over time.

Now, onto the sprayer itself. I swear by the Wagner Flexio 3500 for its affordability and ease of cleaning. It's perfect for furniture projects, thanks to its fine spray pattern and detail nozzle. But if you're looking for affordable alternatives, I've got you covered with a fantastic budget recommendation for you.

Once you've got your top coat and sprayer sorted, it's time to dive into the nitty-gritty of application. Remember to fully stir your top coat to ensure an even finish, and don't forget to strain it to remove any dried bits or debris. And here's a pro tip: adding a bit of water can help extend dry time and improve leveling.

Adjusting your sprayer settings is crucial for achieving that flawless finish. Play around with the flow and airflow until you find the perfect balance for your project. And don't forget to test your settings on a scrap piece before diving into your furniture flip.

When it comes to application, consistency is key. Maintain a steady speed and use overlapping passes for even coverage. And if you encounter any drips or sags, fear not—they can be easily fixed with a bit of sanding.

Speaking of sanding, don't forget to lightly sand between coats for optimal adhesion and smoothness. And remember, practice makes perfect. Don't be afraid to experiment and find what works best for you.
