What is the primary purpose of applying a sealer in refinishing?

The main idea here is that a sealer’s job is to create a smooth, uniform foundation by sealing porosity and evening out color. Porous surfaces will suck in the topcoat differently across the area, which can cause blotching, an uneven finish, and inconsistent adhesion. By filling those tiny pores, the sealer prevents that uneven absorption and helps the topcoat lay down evenly. It also blocks underlying color or stains from showing through, making color more predictable and easier to match. While a sealer can help improve adhesion and may influence how the finish ultimately looks, these are not its primary purposes. Reducing curing time isn’t a primary function of a sealer, and gloss is mainly determined by the topcoat and clearcoat, not the sealer.
