Pohjustuskerros

Pohjustuskerros, meaning primer layer in Finnish, is a foundational coating applied to a surface before the main application of paint or other finishes. Its primary purpose is to prepare the substrate for the subsequent layers, ensuring better adhesion, durability, and a more uniform appearance of the final coating. Pohjustuskerros can be made from various materials, including acrylics, epoxies, or oils, depending on the intended application and the type of surface being treated.

The benefits of using a pohjustuskerros are numerous. It helps to seal porous surfaces, preventing the topcoat from being excessively absorbed and thus reducing the amount of paint needed. It can also neutralize or mask underlying stains, providing a clean canvas for the decorative finish. Furthermore, a well-applied primer improves the overall adhesion of the topcoat, making it less prone to chipping, peeling, or flaking over time. In some cases, a pohjustuskerros can also enhance the color saturation and vibrancy of the final paint color.

Different types of surfaces require different kinds of primers. For example, a metal surface might need a rust-inhibiting primer, while a wooden surface might benefit from a knot-sealing primer. Drywall typically requires a general-purpose latex primer. The correct selection and application of a pohjustuskerros are crucial steps in achieving a professional and long-lasting finish in painting and coating projects.
