Sealers often serve as a crucial intermediary layer, enhancing the adhesion of subsequent topcoats, paints, or varnishes. By creating a uniform surface with improved bonding properties, sealers prevent peeling, cracking, and other finish failures. Consider the application of a sanding sealer before painting; it fills the porous wood surface, allowing the paint to adhere more effectively and resulting in a smoother, more durable finish. This improved adhesion reduces maintenance and extends the service life of the overall finish.
- Preventing Discoloration
Certain wood species and adhesives used in plywood manufacturing can cause discoloration of the finish over time. A sealer can act as a barrier, preventing tannins and other extractives from migrating to the surface and altering the color of the topcoat. For example, using a stain-blocking primer on plywood made with certain tropical hardwoods can prevent unsightly bleed-through that would otherwise compromise the aesthetic appearance of the finished edge. This is particularly important for light-colored or clear finishes.
- Enhancing Finish Uniformity
The edges of plywood tend to absorb finishes unevenly compared to the face veneers. This can result in a blotchy or inconsistent appearance. A sealer helps to even out the absorption rate, ensuring a more uniform and professional-looking finish. Imagine applying a stain directly to an untreated plywood edge; the result would likely be dark and uneven. A sealer, however, pre-treats the wood, allowing the stain to penetrate more consistently and creating a richer, more even color.
These facets highlight the indispensable role of sealers in optimizing the outcome of exposed plywood edge finishing. Whether the goal is to enhance durability, improve aesthetics, or ensure the longevity of the project, the proper selection and application of a suitable sealer are paramount.
