## Description

Review: Fraude en la cantidad - Es importante que pongan que son botes de un litro, la verdad es muy caro para ser solo un litro, la fotografía pertenece a un galón y lo que te envían es un litro. La verdad es un robo porque este producto se vende el Sherwin Williams en galón y cuesta más barato que esto. Para mí es un tremendo fraude.
Review: Good product - Refinished the outside door and applied three layers. The door is facing the sun, in direct sunlight. For 8 months, it has held good. By the way, the application was easy, and it dries fairly fast.

## Questions & Answers

**Q: Can this product be applied to painted surfaces.**
A: I have used it over wood carvings painted with acrylic paints and have have excellent results in an outdoor evironment.

**Q: can i apply the oil based urethane over a water based paint to protect it?**
A: You can but this is why you should use a water based poly over the oil poly Oil based poly has an amber hue, whereas water based poly is clear. An oil based polyurethane will continue to amber and darken over time, while water based poly will remain clear for the lifetime of the hardwood floor. ... Water based poly dries much faster, and several coats (up to 4) can be applied in one day. This explains why fritz the cat who did answer this question as well is why theirs yellowed

**Q: How is the viscocity out of the can, is it more like warm syrup or more like water...or somewhere in between? Thank you!**
A: Maybe Slightly Thinner than warm Syrup, So probably between Warm Syrup & Water. A word of advice though, I had an extremely difficult time working with this product & had to sand and reapply many coats to get a satisfactory finish. It dries fast & if you run a brush over it after is has sat more than a minute it will create rough brush marks. Additionally if you apply more than a very thin layer it will crack similar to a crackle pattern. Unless you are putting this over a pure white background I would recommend that you use the standard "Crystal Clear" non-water based urethane. It has only a light yellow tint and is much easier to work with in my experience.

**Q: Can this product be applied over an exterior wood stain?**
A: In fact it can, but being unfamiliar with the product, I purchase it thinking that it's use would result in a shine. I learned that "spar" must mean something other than gloss or high gloss. I then purchased the "Minwax Gloss aerosol which gave me the desired result, although several coats were required.

### ⭐⭐⭐⭐⭐ Very solid when used correctly
*by M***D on 24 October 2020*

This is one of those products that if you use it correctly it is excellent. It isn't something you just throw on and expect a great result. As they say, prep is everything.. I have used many different sealers- oil based, water based , wipe on products and spray urethanes. All work well depending on project. This is super easy to apply, dries quickly and you can layer many coats in a single day. It also is simple clean up vs oil based products. I have applied with sponge brush as well as high quality nylon brushes and all when used correctly leave great result. For previously stained or sealed wood I sand lightly with with 220 or higher grit sandpaper and make sure it is wiped super clean Absolutely MUST stir very well before and even during application to get good results. First coat should be super light and don't worry about how it looks at this point. Just keep it thin and don't over brush Wait 2+ hours before next coat. Another quick sand, repeat. You will notice each coat goes on easier as it builds and those spots you may have missed now disappear. I didn't sand at all after first two coats. For indoor wood I get great results with 3-4 coats,.outside furniture I put 6 coats on teak and final result was excellent. Living near the beach in Southern CA nothing survives the constant sun and salt air. This does excellent job preserving teak furniture. It DID slightly add a warm amber "tone" to the teak which I like. I have also used on walnut vaneer bath vanity which does get wet and this has worked out very well. You can thin slightly with water if needed but I found the consistentcy very easy to work with and again unlike oil based super easy clean up. I believe anyone who.is having problems is not following directions. I used semi gloss on outside furniture and satin indoor just as a personal preference , both produced great results.
