What is the sequence of steps when preparing a surface that requires a heavily pigmented sealer?

In preparing a surface for a heavily pigmented sealer, the correct sequence of steps emphasizes the importance of surface preparation prior to applying the sealer. Commencing with the application of a sealer helps to not only enhance adhesion but also to provide a uniform base for the subsequent topcoat. Sealers act to fill in pores and surface defects, ensuring that the topcoat goes on smoothly and evenly.

Following the sealer with a primer is essential because primers are designed to bond well with both the sealant and the topcoat, ensuring a durable finish. Primers also provide additional sealing and help in enhancing the paint's adherence to the surface, which is especially important when using a heavily pigmented product that may be prone to issues like peeling or flaking if not applied correctly.

The final step is the application of the topcoat, which adds the desired finish and protects the underlying layers, contributing to the longevity and aesthetic quality of the paint job. This sequence ensures the best results in terms of adhesion, durability, and appearance, making it critical to follow it when working with heavily pigmented sealers.
