Get the second coat on while first coat is damp.
Great stuff! Applied to our bare pine ranch table and benches. It goes a long way and the finish is nice, showing the wood grain and color, though slightly milky. You wouldn't know it if I didn't tell you. I light sanded the wood, vacuumed and wiped down with a wet tack cloth. The sealant goes on easily with a brush and a little goes a long way. Didn't use 1/2 gallon to cover a 120" x 40' table and two 108" x 16" benches, top, bottom and legs with two coats! It did require two people to get the second coat down (instructions said to apply second coat when first is damp), as in the Arizona heat, it was drying pretty fast. The ranch table is out on the covered patio and now I can wipe the dust off in minutes. I'm very please with this product.

Very Pleased!
1/2023 - UpdateI didn't remember to post in 2022, but I wanted to add a couple of pictures. I will say that am not sure if the product is going to hold up through six years (horizontal surfaces like the deck) as it's going on 3 years and I feel like I am seeing wearing I didn't expect. However, I am not a professional. I applied it with a brush and, perhaps, I didn't apply it as well as I should have. I am not comfortable blaming the product alone. Some sections seem to be holding up better than others. Currently, the furniture is covered up, but most of it seems to be holding up better than certain areas of the deck. It should be noted that most of the deck is probably close to 30 years old if not older. That may be a factor as well.6/2021 - UpdateI originally posted last November after treating wooden deck furniture. This June, I treated the deck after having it power washed. Still thrilled with the product and the way it's working. I am adding 2 additional pictures. The first is after the deck was power washed and the second is after I treated/painted it with this product. You can even see beaded water on the deck 🙂11/2020I am posting a review of this product along with some pictures. I will plan on updating it each year as the product is said to last approximately 6 on horizontal surfaces and 10 years on vertical surfaces.First, let me say that I wasn't exactly sure what to expect. When the product arrived I found it to be somewhat thin. When I realized it was water based, it made more sense that it wasn't very thick. That being said, I have been very pleased thus far with the results. I did the application with a brush. As you will see in the pictures, it does what it needs to do when it comes to rain. I also wasn't sure what color to get. I picked the bronze cedar and when used on new wood, that is the color you get. It is beautiful! You will see the color is not quite the same (seems a bit darker depending on the light) when used on wood that has already been treated with a previous product (I don't recall what product or color was on the furniture that I re-treated) It doesn't bother me, though, that the color isn't the same.Now for the pictures. The picture of the deck boards that I treated show the true color. I have not yet treated the rest of the deck as I want to make sure to power wash and clean it first and won't be able to do that till spring. When you see the picture of the boards with the water beaded on them and then see the boards around it don't have beaded water, it's because the rest of the deck has not yet been treated. The pictures of the furniture show the "before" of one of the small end tables and the "after." It also shows an "after" of another chair and table set and big picnic table. Mind you, the furniture wasn't in the best of condition. The last time it was treated was several years ago. I am very pleased with the way this product has worked so far. If you do happen to see an area that was missed, it is NOT the fault of the product, but of the person doing the application (me!) I look forward to treating the rest of the deck (and furniture) in the spring with this excellent product!

DO NOT USE FOR FURNITURE
The media could not be loaded. I bought this product specifically for outdoor furniture I had made. More specifically, for an outdoor table and some other projects I’m working on. This product should not be used on furniture at all.The finish after curing for three days is a glossy semi gloss finish. It is tacky to the touch, It has rendered my furniture unusable until I seal it with another product that I know will work from Home Depot.If you plan on using this product for something like fences, I understand how it might work better. It seems to repel water pretty well when I test it, However, if I put anything on this table, it will leave marks because it does not cure solid. It stays tacky.For that reason, I also don’t know if I would use this on any other outdoor use cases because things like dust and dirt will accumulate on the sealant.Thankfully, I’ve only used this product on my table, And as an extra coat on some existing furniture and not my other projects.If you don’t care about dust or dirt accumulating on whatever you apply this to then sure go for it.However, I will be returning this product because it does not work as advertised, and there are other superior products out there…

Used it on my Trailer
20’x80” car trailer. Application was easy, the treated wood on the trailer soaked it up nicely. I’m sure it will lighten up a bit after it cures. Looks great! I used a stain applicator tool, and a 2” brush for between the boards.
