It may cost some money but you get what you pay for in this Nano stain and seal. Its amazing Review: Yep - Very easy to apply and dries quickly. Used it on old treated lumber that I power washed and made into a boat dock. Water beads up and the color looks great.

It's odorless and ideal for use on wood siding, log homes, swing sets, outdoor furniture, wooden deck and fence, and more. - 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. - FLOOR SEALER APPLICATOR: Our premium gloss is ultra-low VOC and great for enhancing 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. - SEAL-ONCE: Our user-friendly wood sealers and stains are an effective way to protect your lumber or concrete against water damage. When you use Seal-Once, you have the satisfaction of knowing our products will not harm pets, plants, or people. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B087YRCZ32 | | Best Sellers Rank | #3,308 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #26 in Household Stains | | Brand | Seal-Once | | Brand Name | Seal-Once | | Color | Bronze Cedar | | Compatible Material | Wood | | Customer Reviews | 4.2 out of 5 stars 1,471 Reviews | | Item Dimensions | 10 x 4 x 10 inches | | Item Form | Liquid | | Item Weight | 9 Pounds | | Item dimensions L x W x H | 10 x 4 x 10 inches | | Manufacturer | UC Coatings | | Material | Polyurethane | | Material Type | Polyurethane | | Model | S07507 | | Part Number | S07507 | | Style | Protection | | Style Name | Protection | | Surface Recommendation | Furniture,Siding,Wood | | UPC | 850009973009 | | Unit Count | 128 Fluid Ounces | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Seal-Once - **Item Weight:** 9 Pounds - **Item dimensions L x W x H:** 10 x 4 x 10 inches - **Material:** Polyurethane - **Style:** Protection ## Images ![Seal-Once Nano+Poly Penetrating Wood Sealer with Polyurethane - Premium Waterproof Sealant -1 Gallon & Bronze Cedar - Image 1](https://m.media-amazon.com/images/I/818Aho9mKYL.jpg) ![Seal-Once Nano+Poly Penetrating Wood Sealer with Polyurethane - Premium Waterproof Sealant -1 Gallon & Bronze Cedar - Image 2](https://m.media-amazon.com/images/I/81209v-EnpL.jpg) ![Seal-Once Nano+Poly Penetrating Wood Sealer with Polyurethane - Premium Waterproof Sealant -1 Gallon & Bronze Cedar - Image 3](https://m.media-amazon.com/images/I/71-kHKQX+IL.jpg) ![Seal-Once Nano+Poly Penetrating Wood Sealer with Polyurethane - Premium Waterproof Sealant -1 Gallon & Bronze Cedar - Image 4](https://m.media-amazon.com/images/I/81JAh4NPp2L.jpg) ![Seal-Once Nano+Poly Penetrating Wood Sealer with Polyurethane - Premium Waterproof Sealant -1 Gallon & Bronze Cedar - Image 5](https://m.media-amazon.com/images/I/91jIbWCF5cL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality and durability, looks amazing!! *by S***E on May 28, 2026* I've used so many different stains and waterproofing and by far this is hands down the best ever.
