About this item
- Water-based Wood Finish: Our sealant provides top-notch protection against wear and tear in high traffic areas. It's odorless and suitable for use on wood siding, log homes, swing sets, outdoor furniture, wooden deck and fence, and more
- Penetrating Wood Sealant: Unlike many sealers that only form a topcoat, our protector penetrates below the surface to create a long-lasting, water-resistant shield around the wood. It helps protect against the elements
- Ultra-low Voc Floor Sealer: Our premium gloss is ultra-low VOC and enhances the extended life of your exterior flooring. The sealant can be safely applied around your home, landscaping, vegetation, or over any water area
- Waterproof Sealer: Ditch the oil-based sealers and choose a UV-stable coating option. Our fast-drying liquid creates a flexible, breathable barrier and provides a no-fuss, easy clean-up with soap and water, as it allows the wood to grey naturally
- Non-toxic Wood Protection: Our user-friendly wood sealers and stains are an effective way to protect your lumber against water damage. When you use Seal-Once, you have the satisfaction of knowing our products will not harm pets, plants, or people
- Long-lasting Warranty Coverage: This wood sealer is warranted to protect against water accumulation for up to 10 years on vertical surfaces and 6 years on horizontal surfaces, providing reliable long-term protection
- Versatile Color Options: Can be tinted and used as wood stain or finish in 9 semi-transparent color tints including Coastal Gray, Black, Bronze Cedar, Brown, Cedar, Light Brown, Mahogany, Natural, Redwood.
