5. Preparation
Proper surface preparation is crucial for optimal stain performance and longevity.
- Clean Surface: Ensure the wood surface is clean, dry, and free from dirt, mildew, old finishes, and other contaminants. Use a suitable wood cleaner if necessary, following the cleaner's instructions.
- Rinse Thoroughly: Rinse the surface thoroughly with water to remove all cleaning solution residue.
- Allow to Dry: Allow the wood to dry completely. This may take several days depending on weather conditions and wood type. Moisture content should be below 15%.
- Sanding (Optional): For smoother finishes or to remove minor imperfections, light sanding with fine-grit sandpaper (e.g., 80-120 grit) may be performed. Remove all sanding dust before application.
- Temperature and Humidity: Apply when air and surface temperatures are between 40°F (4°C) and 90°F (32°C). Avoid application in direct sunlight, high humidity, or if rain is expected within 24-48 hours.
- Test Area: Always apply to a small, inconspicuous area first to ensure desired color and appearance.
6. Application (Operating Instructions)
Follow these steps for effective application of Messmer's U.V. Plus Semi-Transparent Stain.
- Stir Thoroughly: Stir the stain thoroughly before and during application to ensure color consistency. Do not thin the product.
- Application Methods:
- Brush: Use a high-quality natural bristle brush. Apply in the direction of the wood grain.
- Roller: Use a short-nap roller cover. Apply evenly, then back-brush to ensure penetration and even coverage.
- Airless Spray: Follow manufacturer's recommendations for tip size and pressure. Back-brush immediately after spraying to ensure even penetration and avoid lap marks.
- Apply Evenly: Apply a thin, even coat. Avoid over-application, which can lead to a sticky finish or uneven drying.
- Coverage:
- For rough wood: Approximately 100 - 150 sq-ft per gallon.
- For smooth wood: Approximately 150 - 250 sq-ft per gallon.
- Drying Time: The stain is typically dry to the touch within 24 hours under ideal conditions (40-90°F, moderate humidity). Allow sufficient time before heavy use or exposure to moisture.
- Additional Coats: A single coat is usually sufficient for most applications. If a second coat is desired for deeper color, apply it wet-on-wet or within a few hours of the first coat, ensuring the first coat has not fully dried. Do not allow the first coat to dry completely before applying a second coat, as this may prevent proper penetration and lead to peeling.
7. Maintenance
To maintain the appearance and protection of your stained wood surface:
- Regular Cleaning: Clean the stained surface periodically with a mild detergent and water to remove dirt, pollen, and other debris. Avoid harsh chemicals or abrasive cleaners.
- Inspect Annually: Inspect the wood annually for signs of wear, fading, or mildew.
- Reapplication: Reapply Messmer's U.V. Plus Stain as needed, typically every 1-3 years depending on exposure and traffic. Clean the surface thoroughly before reapplication.
8. Troubleshooting
- Sticky or Tacky Surface: This usually indicates over-application or insufficient drying time. Ensure thin, even coats and allow proper ventilation. If tacky, try wiping with a rag dampened with mineral spirits (test in an inconspicuous area first).
- Uneven Color: Can be caused by improper stirring, uneven application, or inconsistent wood porosity. Ensure thorough stirring and even application. A test area is recommended.
- Peeling: Messmer's U.V. Plus is designed not to peel when properly applied. Peeling typically occurs if the surface was not properly prepared (e.g., old finishes not removed, surface not clean/dry) or if too many coats were applied, preventing proper penetration.
- Mildew Growth: While the stain resists mildew, extreme conditions can still lead to growth. Clean affected areas with a mildew cleaner and reapply stain if necessary.
9. Storage and Disposal
- Storage: Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Keep container tightly closed when not in use. Do not freeze.
- Disposal: Dispose of unused product and empty containers in accordance with all local, state, and federal regulations. Do not pour down drains or dispose of in waterways. Consult local waste management authorities for proper disposal methods.
- Rags and Waste: Rags, steel wool, and other waste soaked with this product may spontaneously catch fire if improperly discarded. Immediately place all such materials in a sealed, water-filled metal container.
