Professional Application System (1 to 2 Coats) Weatherall SuSTAIN is engineered for high-efficiency protection with a single-coat application, which fully locks in the 3-Year Limited Warranty. However, you can apply a second coat if you desire an even richer, deeper color profile or enhanced film thickness. When applying a second coat, allow proper tack-free drying time between passes to ensure a clean, uniform finish.

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 Flexible Coat Application: Delivers complete, durable protection in a single pass to save time, while fully supporting a secondary coat for projects requiring a deeper color saturation. 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 limited to only one coat of SuSTAIN? A: No. While a single coat is highly effective and qualifies for the 3-Year Limited Warranty, you can absolutely apply a second coat if you desire a darker appearance or extra protective build.
