When applying, use long, even strokes or rolls, and maintain a consistent pressure to ensure uniform coverage. It's also important to work in sections, completing one area before moving on to the next, to prevent the polyurethane from drying unevenly.
In addition to using the right tools and techniques, it's essential to prepare the surface properly before applying polyurethane. Ensure that the interior paint is fully dry and free of dust, dirt, or grease. Lightly sanding the surface with fine-grit sandpaper can help improve adhesion and create a smoother finish. After sanding, wipe down the surface with a tack cloth or damp rag to remove any debris.
When applying polyurethane, it's important to work in a well-ventilated area and use personal protective equipment, such as gloves and a mask, to avoid inhaling fumes or getting the product on your skin. Follow the manufacturer's instructions for drying times and the number of coats required for optimal results. Typically, two to three coats of polyurethane are recommended for interior surfaces, with each coat being applied in the same manner as the first.
By following these guidelines and using high-quality tools, you can achieve a professional-looking finish when applying polyurethane over interior paint. Remember to work patiently and methodically, and don't hesitate to seek advice from a professional if you're unsure about any aspect of the process.

Sanding: Lightly sand between coats with fine-grit sandpaper for a smooth finish
Sanding between coats of polyurethane is a critical step in achieving a smooth, professional finish on interior painted surfaces. This process helps to remove any dust, debris, or minor imperfections that may have settled on the surface after the initial coat has dried. By lightly sanding with fine-grit sandpaper, you create a more even base for the subsequent coat of polyurethane, which enhances adhesion and reduces the likelihood of a textured or uneven finish.
When sanding, it's essential to use a fine-grit sandpaper, typically in the range of 320 to 400 grit. This fine grit ensures that you don't accidentally scratch or damage the underlying paint while still effectively removing any surface contaminants. Always sand in the direction of the wood grain to avoid creating swirl marks or scratches that can be difficult to remove later.
After sanding, it's crucial to thoroughly clean the surface to remove any dust or debris generated during the sanding process.
