Q: Is this non-skid?

5 months ago
1 Answer
  • A: It is not non-skid. It is a water proofer that will bead water on top of the wood. Water on top of wood is slippery. Also, you cannot add anti-skid additives to any Seal-Once product. Investigate using 3M no-skid strips. They come in clear and colors.

Average at best

2 months ago
Purchased last month. Can hardly call it a stain, more like somewhat transparent. Following their directions, WILL NOT flow through a pump up style garden sprayer. Using a longer nap roller to back roller, as recommended, still would not fall between the boards. Will need to go over it with a brush. Slippery when wet, not great for a deck. Application was okay, provider you could back roller immediately. First coat seemed to sucked in immediately, where second coat all but eliminated the woods grain

No, I do not recommend this product.

Brings life back to old, grey wood

2 months ago
I wish I would have taken before pics! This deck was grey and ugly! I applied the suggested cleaner, power washed it and sanded a few spots. I had to fill a few cracked spots that are visible after painting. It was relatively easy to apply, however there are some lap marks where I painted under the railings prior to painting the floor boards. It’s not very forgiving with drips, either. Not a big deal for me at all and overall very pleased with the finished product! It brought life back to my old, grey deck! Hoping it lasts as long as it says it does! Color is light brown.

Yes, I recommend this product.

Very good product for wood

2 months ago
The wood finish applies smoothly and evenly, allowing for excellent coverage with minimal effort. It’s consistently is easy to work with helping the brush glide across the wood surface without leaving noticeable streaks or brush marks.

Revitalized an old picnic table

2 months ago
Really soaked into the wood, as i was hoping. No fear of a peeling coating. After a sanding and a couple brush coats of this product, the table looks nearly new again.

Yes, I recommend this product.

It’s nice!

3 months ago
We used this up north at our cabin on the lake. It worked so well! We just redid our stairs after the winter and this stain was very easy to go on and covered a very wide range of the steps! It went on easy and was not hard to prepare and did not take too many tools to do.

Best Dock Paint

3 months ago
Needed to extend the life of an old dock until it can eventually be replaced. Used 6 gallons of this sealer in Coastal Gray to seal the old pressure washed boards. Very pleased with the outcome, ease of use and quality of the product. Seals so water beads up and is not absorbed. Prevents splinters too.

Yes, I recommend this product.

Transparent wood stain

3 months ago
This wood stain gives a nice warm cedar tone but is still transparent to show the natural wood grain. It goes on smoothly and is easy to apply. It’s made for outdoor conditions so I feel good that it will hold up over time. Overall it’s done what I needed.

Rich wood stain for patio cover

3 months ago
I love how this wood stain made our tired old patio cover look! You can see that it really revitalized the exterior and will hopefully help it last longer. Unfortunately I really do not like the cheap plastic can that it comes in. The handle popped out of the plastic tab on the side and it spilled all over the box in transit. Would be a perfect score if the packaging were better.

This product dries fast and still looks good

4 months ago
This product had a great consistency, not too thin and not to thick. My wood absorbed this product so fast and has a great color when it dried. I am going to hit it with one more coat before I burn the sides for a rustic look.

Transparent, natural looking stain

4 months ago
I did a small test application on untreated wood before committing to a larger deck project. First impressions were positive. The stain goes on very easily and has a thin, water-based consistency that absorbs into the wood quickly instead of sitting heavily on the surface like some thicker oil based products. The bronze cedar color came out warm and natural looking and enhancing the grain without completely covering it up. One thing I liked immediately was that it didn't have an overpowering chemical smell and clean up was easy.

Easy to apply, quick drying

This semi transparent wood stain goes on smooth, dries quick, and is easy to cleanup. The color is a nice warm tone and really stands up strong to cracking.

Gorgeous on wood projects around the pool!

4 months ago
The Marine Grade Broze Cedar Wood Stain is absolutely beautiful on flower beds around my pool. The wood grain shows through perfectly. The color is consistent across my whole project, and not runny or drippy. It is so easy to apply and just as easy to clean up the brushes with warm, soapy water.

We love the finished product of our project thanks to seal-once bronze cedar stain. It stained so nicely and really grasped onto the wood. It went on smoothly and spread easily. Happy with the overall experience.

Best wood stain on the market!!!!

4 months ago
The Marine grade Bronze Cedar premium semi-transparent wood stain is a game changer!! One coat of stain is all you need. It glides on very easy. I had no preparation just shook it and it was ready to go. It adheres to the wood fast and doesn’t leave splotchy patches. Didn’t have to scrub off excess that was dripping. This stuff is amazing. I’m definitely gonna go get some other colors. It does take some time to dry. but if you’re looking for the best easiest wood stain on the market, this is the stuff.

Elevate you wooden gates!

5 months ago
The Seal Once is an amazing stain upgrading your outdoor wooden gates. I did it for a little gate fence and a larger gate. It was easy and took maybe 2 hours to elevate and bring back to life our wooden gates. It was easy to apply with just a brush. I did 2 coats and the wood came out a beautiful deep brown finish. The wood looks amazing and leaves a smooth feel. The gallon can goes a very long way as we still have over half still full.

Saturation Upon One Application

5 months ago
Immediate saturation upon applying a single coat. The before and after photos don’t do my deck tiles justice. They are completely weather worn from UV rays by the beach and worn down by salty air. The stain goes on smooth and looks fantastic!

Marine grade coverage!

5 months ago
Beautiful packaging. Super easy application not very strong of an odor but I still wore a mask. I used to seal a wooden frame and it did a great job. I’m excited about it being marine grade so I can trust that it is sealed well and will not requiere much maintenance.

Currently spot testing my dock and parts of my deck as I live in a lake and so far so good, it applies with ease and isn't runny like other wood strains I've used in the past. I can't wait to see the finished result and I'll update this review when I do!!
