Review: Seals and protects outdoor work tables. Attractive and easy to clean. - Purchased both the clear and the dark cedar. Both worked well on some wood work table I have outdoors under cover but where they receive plenty of sunlight. I used two coats each of the clear on the sanded plywood tops and the dark cedar on the structure and legs underneath. Goes on easily, seals and protects. Appears to be entirely waterproof. Seems to be holding up very well so far over the course of several months. The dark cedar staining was a little hard to prevent being streaky but not too bad and is an attractive rich color. I really like the satin surface quality. The tables are easy to wipe down and clean. I've been using them primarily for clay work.
Review: Do your research! - If you spend any time online researching deck sealants, this product will keep popping up. So, of course, I assumed it was paid advertisement. Off to forums I went, and there too, Seal Once was the recommended choice. This product is a lot thicker than competitors and was really pretty easy to apply. There was little splatter using a roller. No strong odor. It dried to the touch within an hour, but I left it overnight to be certain. The clear version did NOT stain our deck, but did add a low sheen ( which we like). The ONLY negative comment would be: in a couple places we got a bit sloppy and didnt notice. So, now when it rains, those spots turn white. Luckily its in a place that doesnt really stand out. I have not found any spots where the sealant has not adhered or worn off ( we applied this about 3 months ago now). Imo, worth every cent. Will definitely purchase again when needed.

## Features

- WATER-BASED POLYURETHANE 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 WITH UV STABILITY: 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
- NANOTECHNOLOGY FORMULA: Proprietary nanotechnology combines with polyurethane strength to provide 360-degree protection by coating wood fibers at the cellular level, creating a durable and breathable barrier
- 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.

### ⭐⭐⭐⭐⭐ Easy and love the finish!
*by T***A on August 9, 2026*

Put two coats on well dried out pressure treated lumber today. Boom. Easy. I put it on with a 6” roller for semi smooth semi rough surfaces. It was applied evenly and sloppily, I did my best but it’s a garden path ramp, I’m not worried about finish quality. There was a thick white streak of resin on some passes, but you can’t see it at all in how it dries.
