2. Safety Information

DANGER: HARMFUL OR FATAL IF SWALLOWED. COMBUSTIBLE. Read all cautions on the product label before use. Keep out of reach of children. Use in a well-ventilated area. Wear appropriate personal protective equipment, including chemical-resistant gloves, eye protection, and respiratory protection if ventilation is inadequate. Avoid contact with skin and eyes. In case of contact, flush immediately with plenty of water. If swallowed, do not induce vomiting; call a poison control center or doctor immediately. Dispose of rags and waste materials properly to prevent spontaneous combustion.

3. Preparation and Setup

3.1 Surface Preparation

• Ensure the wood surface is clean, dry, and free of dirt, mildew, algae, and any previous coatings or sealers.
• New Wood: Allow new wood to weather for 3-6 months to open the wood pores, or clean with a suitable wood cleaner/brightener according to product directions.
• Old/Weathered Wood: Thoroughly clean the surface with a Messmer's wood cleaner and brightener to remove graying, dirt, and mildew. Rinse thoroughly and allow to dry completely.
• Ensure the wood moisture content is below 15% before application. Use a moisture meter for accuracy.
• Cover surrounding areas, plants, and non-wood surfaces to protect them from drips or overspray.

3.2 Environmental Conditions

• Apply when air and surface temperatures are between 50°F (10°C) and 90°F (32°C).
• Avoid applying in direct sunlight, on hot surfaces, or when rain is expected within 24-48 hours.
• Ensure good ventilation during application.

4. Application (Operating)

4.1 Application Instructions

1. Stir the product thoroughly before and periodically during use to ensure uniform consistency and color.
2. Apply one even coat of Messmer's UV Plus Wood Finish using a brush, roller, or sprayer.
3. Work in small sections, applying the finish uniformly.
4. Do not overapply. The wood should appear wet but not have puddles or thick film on the surface.
5. Within 30 minutes of application, wipe off any excess finish that has not penetrated the wood using a clean, dry cloth. Failure to wipe off excess can result in shiny spots or a tacky surface.
6. Allow the surface to dry completely before light foot traffic.

4.2 Drying and Curing Times

• Touch Dry: Approximately 6-12 hours, depending on temperature, humidity, and wood porosity.
• Light Foot Traffic: 24-48 hours.
• Full Cure: 72 hours for full hardness and water resistance. Avoid heavy use or placing furniture on the surface during this period.

5. Maintenance

5.1 Routine Cleaning

• Clean finished surfaces annually, or as needed, with a mild detergent and water. Avoid harsh chemicals or abrasive cleaners.
• Rinse thoroughly with clean water after cleaning.

5.2 Reapplication

• Reapply Messmer's UV Plus Wood Finish as needed, typically every 1-3 years, depending on exposure to sun, weather, and traffic.
• Signs that reapplication is needed include fading color, increased water absorption, or a dull appearance.
• Before reapplication, clean and prepare the surface as described in the "Preparation and Setup" section (Section 3). A full stripping is usually not required for reapplication of a penetrating finish.

6. Troubleshooting

• Uneven Finish: This can be caused by uneven application or failure to wipe off excess product. Ensure even application and proper wiping within 30 minutes. If dry, a light sanding and reapplication may be necessary.
• Tacky or Sticky Surface: Typically results from overapplication or applying in high humidity/low temperatures. Ensure proper application thickness and environmental conditions. If tacky, try wiping with a clean cloth dampened with mineral spirits (test in an inconspicuous area first).
• Slow Drying: High humidity, low temperatures, or overapplication can prolong drying times. Ensure proper conditions and application thickness. Good air circulation can help.
• Peeling or Flaking: This is not typical for a penetrating oil finish. If this occurs, it is usually due to surface contamination or applying over a previous film-forming finish. Ensure thorough surface preparation as outlined in Section 3.1.
