    Common Mistakes

    Common errors to avoid in your coursework

    • Inadequate surface preparation, such as skipping grits or sanding across the grain, leading to visible scratches and poor stain absorption.
    • Applying finishing products too heavily or without proper thinning, resulting in runs, curtaining, or extended drying times.
    • Misinterpreting the effect of wood species and colour, causing the final colour to differ significantly from the client’s sample or specification.
    • Neglecting to stir or strain finishing materials, which introduces lumps, uneven gloss, or colour streaks into the final coat.
    • Using contaminated cloths or brushes, or not removing dust between coats, causing nibs and poor inter-coat adhesion.
    • Skipping grits when sanding, leading to visible scratches on the finished surface.
    • Over-application of finish causing runs, pooling, or slow drying in corners and edges.
    • Inadequate cleaning of surfaces before finishing, resulting in poor adhesion and a contaminated finish.
    • Misidentifying the type of existing finish on a restoration piece, leading to incompatibility with new coatings.
    • Rushing surface preparation by skipping intermediate grits, leading to visible scratches under the finish.
    • Applying French polish too thickly without proper padding, causing cloudy bloom or uneven gloss.
    • Using incompatible products over existing finishes without testing, resulting in adhesion failure or chemical reaction.
    • Neglecting humidity and dust control, which compromises drying times and final surface clarity.
    • **Misconception:** All finishes are applied using the same basic technique. **Correction:** Different finishes have unique viscosities, drying times, and curing mechanisms, requiring specific application methods (e.g., a fast-drying lacquer sprayed thinly versus a slow-drying oil wiped on and buffed) to achieve optimal results and avoid defects.
    • **Misconception:** Surface preparation is a minor step that can be rushed. **Correction:** Inadequate surface preparation (e.g., insufficient sanding, leaving dust or grease) is the leading cause of finishing failures like poor adhesion, uneven absorption, and visible imperfections, making it the most critical stage for a high-quality finish.
    • **Misconception:** More coats of finish always result in a more durable or better-looking product. **Correction:** Applying too many coats, or coats that are too thick, can lead to issues such as cracking, peeling, prolonged drying times, loss of detail, and a 'plastic' appearance. Achieving the correct film build for the specific finish type is key to both durability and aesthetics.
