Following are a few situations where we recommend the use of Prelude:
1. After a home has been media blasted.
2. If a home is aggressively pressure washed to the point where the surface is feathered and the porosity of the wood varies from area to area.
3. On wood where the surface has been unevenly sanded.
4. On rough cut siding before the application of the color coat(s).
5. If a section of a wall has been repaired or replaced and the new sections don’t match the surface characteristics of the old.
6. Whenever an older home (more than 80 years old) is going to be restored. Once the surface of old wood is cleaned of grayed wood it typically takes on the porosity characteristics of a blasted surface.
7. Whenever you want to use only clear coats on interior surfaces. Although Interior Clear can be used, the use of Prelude as the first sealing coat is a somewhat better deal, since it already contains UV Boost. Once the Prelude dries, Acrylic Gloss or Satin or Sure Shine™ Gloss or Satin can be applied over it.
8. Whenever a home is completed but may remain without an exterior finish for many months, a coat of Prelude will help prevent surface graying and make it easier to clean when it comes time to stain.
There may be other occasions when a priming coat of Prelude will make a home more attractive, easier to stain or add to the longevity of the finish system, but it should never be used on smooth surfaced wood to obtain a lighter final color. Prelude should never be used as the final coat. It is a primer and must always be covered with one of our interior or exterior finish systems.
