    Applies easily. Seems like the manufacturer has tested the product with the appropriate labs. I hope that we never have to test on the applied materials. We like this product !

    Goes on easily. Must choose cool of day - not 85 or over. We have been in the mid 90's so painted early this AM.

    we just received and are in the process of applying product to both our deck, doors, and fence.
    this is not the first time we've done this but first time with this product and we like it better than anything else we've used so far.
    easy to apply, and clear so the wood shows thru,

    Just what we needed

    The product is fantastic. Easy to install. I hope to never have to test it out. All the documents and tests will be good to have if the city needs to see what we treated the lumber with. Also, the team was outstanding. They answered every question we had.

    Might be a good product. Unfortunately, product sheet only discusses its universal application. The technical sheet explains that you can only use WATER BASED products on it. I need a product that will accept an oil base stain.

    I applied it. Application was very easy. I am using it on siding. I have top coated it with a clear sealer. There have been no fires in my neighborhood threatening my home, so I don't know how if it protects my home yet.
