Neglecting proper preparation can result in a compromised final product, regardless of the quality of the finish itself.
- Sanding: Achieving a Smooth Base
Sanding serves to remove imperfections, open the wood pores, and create a consistent texture. Progressively finer grits of sandpaper, typically starting with 120 and moving to 220 or 320, are employed. Failure to sand adequately can lead to uneven finish absorption and a rough or textured surface. An example includes poorly sanded cedar paneling displaying visible scratches beneath a clear coat finish.
- Cleaning: Removing Contaminants
After sanding, the removal of dust, debris, and any existing contaminants is critical. Vacuuming followed by wiping with a tack cloth ensures a clean surface free from particles that could interfere with finish adhesion and appearance. For instance, residual sawdust left on the cedar prior to finishing can create a cloudy or speckled effect in the final result.
- Addressing Imperfections: Repairing Flaws
Prior to finishing, any imperfections such as knots, gouges, or cracks should be addressed. Wood filler or epoxy can be used to repair these flaws, creating a uniform surface for the finish. Untreated imperfections will be accentuated by the finish, detracting from the overall aesthetic. For example, an unpatched nail hole in cedar trim becomes highly visible after the application of a stain.
- Assessing Moisture Content: Preventing Issues
The moisture content of the cedar should be within an acceptable range (typically 6-8% for interior applications) before finishing. Excess moisture can prevent proper finish adhesion and lead to issues like blistering or peeling. Allowing cedar to acclimate to the interior environment before finishing helps to stabilize moisture content. Using a moisture meter can confirm the wood is ready. For example, finishing cedar directly after it has been transported from a humid environment to a dry interior can cause problems.
The aforementioned facets of surface preparation work in concert to provide an optimal foundation for finishing interior cedar. Thoroughly addressing each aspect ensures that the chosen finish adheres properly, highlights the natural beauty of the wood, and provides long-lasting protection.
