4. Setup and Surface Preparation
Proper surface preparation is crucial for the optimal performance and longevity of TWP Total Wood Preservative. Ensure the wood surface is clean, dry, and free from any previous coatings that might hinder penetration.
Required Tools and Materials:
- TWP Total Wood Preservative (TWP101-1G Cedar)
- Stir stick
- Applicator (brush, roller, or pump sprayer)
- Drop cloths or plastic sheeting to protect surrounding areas
- Cleaning solution (wood cleaner/brightener, if necessary)
- Stiff bristle brush or pressure washer (for cleaning)
- Personal Protective Equipment (gloves, eye protection, respirator)
Surface Preparation Steps:
- Clean the Wood: Remove all dirt, grime, mildew, and loose wood fibers. For heavily soiled or previously coated surfaces, use a suitable wood cleaner and brightener according to its instructions. Rinse thoroughly with water.
- Remove Old Finishes: If the wood has a previous film-forming finish (paint, varnish, solid stain), it must be completely removed by stripping or sanding to allow the TWP preservative to penetrate properly.
- Allow to Dry: Ensure the wood surface is completely dry before application. This typically takes 24-48 hours after cleaning, depending on weather conditions and wood type. Moisture content should be below 15%.
- Protect Surroundings: Cover any adjacent surfaces, plants, or landscaping with drop cloths or plastic sheeting to prevent accidental spills or overspray.
5. Application Instructions
Follow these steps carefully for effective application of TWP Total Wood Preservative.
- Stir Thoroughly: Before and during application, stir the TWP Total Wood Preservative thoroughly to ensure all pigments and solids are evenly dispersed. Do not shake.
- Test Area: Always apply to a small, inconspicuous area first to verify color and penetration before proceeding with the entire project.
- Apply Evenly: Apply a liberal, even coat of the product to the wood surface using a brush, roller, or pump sprayer. Ensure complete saturation of the wood.
- Wet-on-Wet Application (for porous wood): For very porous wood, a second coat may be applied immediately after the first coat, while the first coat is still wet. This "wet-on-wet" method allows for maximum penetration. Do not allow the first coat to dry before applying the second.
- Remove Excess: After 20-30 minutes, or before the product begins to dry, back-brush or wipe off any excess material that has not penetrated the wood. Puddles or shiny spots indicate excess product, which can lead to an uneven finish or premature wear.
- Drying Time: Allow the treated surface to dry completely. Drying time can vary based on temperature, humidity, and wood porosity, but typically ranges from 24-72 hours before light foot traffic. Full cure may take several days.
- Coverage: One gallon typically covers approximately 250-400 square feet, depending on wood porosity and application method.

6. Maintenance
TWP Total Wood Preservative is designed for easy maintenance due to its non-cracking, non-peeling, and non-blistering properties. Regular cleaning and periodic reapplication will extend the life and beauty of your wood.
- Regular Cleaning: Clean the treated wood surface periodically with a mild detergent and water to remove dirt, dust, and light mildew. Rinse thoroughly.
- Reapplication: The frequency of reapplication depends on exposure to sunlight, weather conditions, and traffic. Typically, reapplication is needed every 2-5 years. Look for signs of fading, graying, or reduced water repellency as indicators for reapplication.
- Preparation for Reapplication: For reapplication, simply clean the surface thoroughly to remove any dirt or mildew. A light sanding may be beneficial for heavily weathered areas. Ensure the surface is dry before applying a new coat. No stripping is usually required unless a film has formed due to over-application.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven Color / Shiny Spots | Over-application; excess product not wiped off. | Wipe off excess product with a rag before it dries. If dry, a light sanding and reapplication may be necessary. |
| Poor Penetration / Flaking | Surface not properly cleaned; old finish not removed; wood too wet. | Ensure wood is clean, dry, and free of old finishes. Re-prepare surface if necessary. |
| Slow Drying Time | High humidity; low temperature; over-application. | Ensure good ventilation. Avoid applying in high humidity or cold temperatures. Wipe off any excess product. |
| Mildew Growth | Persistent moisture; inadequate cleaning before application. | Clean the affected area with a mildew cleaner. Ensure proper drainage around the wood. |
