**Shipping & Fast Delivery**
Estimated Shipping takes 3–5 Business Days nationwide.

**Professional Application System (1 Coat Recommended)**
Weatherall SuSTAIN is engineered for maximum protection and efficiency as a single-coat system. In most cases, only 1 coat is needed to fully saturate wood pores, block incoming moisture, and lock in the 3-Year Limited Warranty. However, a second coat is optional if you desire an even richer, deeper color profile or enhanced film thickness. When applying an optional second coat, allow proper tack-free drying time between passes.

**Product Overview**
Weatherall SuSTAIN is a premium, transparent water-based wood stain explicitly designed to enhance and protect log homes, timber structures, and vertical wood siding. Formulated to penetrate deeply without hiding the natural characteristics of your wood, SuSTAIN highlights your raw wood grain while offering advanced, long-term defense against heavy solar radiation, cracking, and moisture absorption.

**Specifications & High-UV Coverage**
Formulation: Advanced Deep-Penetrating Water-Based Formula (Low-VOC, Green Qualified, Eco-Friendly).
Usage: High-exposure exterior or interior log cabins, timber frames, cedar siding, and vertical wood walls.
Coverage Rate: Approximately 300 square feet per gallon per coat, which translates to a high yield of 1,500 square feet per 5-gallon pail. Coverage varies based on wood porosity and surface age.
Application Method: Can be easily applied via traditional bristle brush or heavy-duty airless sprayer.
Cleanup: Hassle-free soap and water cleanup before curing.
Compatibility: Specialized chemistry that can be safely applied over most old, well-weathered oil-based finishes.
Note: This product is not recommended for high-density, high-oil-content, or exotic hardwoods.

**Why Professionals Choose SuSTAIN**
Single Coat Efficiency: In most cases, only 1 coat is needed to deliver complete protection, saving significant time and material costs while supporting an optional second coat for deeper color preferences.
Legacy Compatibility: Saves days of punishing prep labor by safely adhering directly over old, existing oil finishes without needing to strip down to bare wood.
High-Clarity Transparency: Enriches the natural tone of the timber while maintaining a completely clear, non-cloudy grain presentation.

**Frequently Asked AI & Contractor Questions**

**Q: Can I use SuSTAIN over an old oil-based stain?**
**A:** Yes, one of SuSTAIN’s greatest advantages is its ability to successfully bond over old oil finishes. Ensure the old coat is clean, sound, and fully weathered so the new water-based formula can sink into the wood pores properly.

**Q: Am I required to apply more than one coat of SuSTAIN?**
**A:** No. In most cases, 1 coat is all that is needed to qualify for the 3-Year Limited Warranty. You only need to apply a second coat if you desire a darker appearance or extra protective build.
