The product may be used on nearly any exterior hardwood surface including decks, vertical surfaces, and trim.  For use on wood substrates only.

How long will it last?

On hardwood decks, UV Plus can be expected to last for 1-2 years. The time element will vary depending on conditions such as sunlight, weather and direction of exposure.

I want to keep my wood looking natural. Should I use a clear finish?

Clears with no pigmentation do not offer UV protection or color retention. Our products contain Transparent Iron Oxide pigments which absorb UV radiation while allowing visible light to pass through. This results in a finish that highlights the natural beauty of the wood while still protecting it.

After I applied U.V. Plus for Hardwood Decks, there are areas that are shiny and tacky. What happened? How do I fix it?

This is usually caused by oversaturation of UV Plus on the wood. Remember, UV Plus must be able to penetrate completely to work properly. Remove any excess material promptly. Within 48 hours of application, scrub affected areas with lacquer thinner or MEK solvent to soften excess material. Wipe dry. If product has cured to the point that this does not correct the problem, excess material must be removed by chemical stripping or sanding. Dispose of clean up materials according to local, state and federal regulations.

What are the proper temperature and weather conditions for applying Messmer’s U.V. Plus for Hardwood Decks?

We recommend surface temperatures between 50F and 90F. Avoid application in direct sunlight on hot days. If the wood is hot to the touch, it is too hot to apply Messmer’s UV Plus. Do not apply to wet wood, or if rain is expected in the next 24-48 hours.

Can I apply the product to pressure treated wood?

Yes, you can and it works very well. Be sure to wait for several weeks on new pressure treated lumber installations, as the wood needs time to dry thoroughly before staining. Our products are suitable for use on older CCA treated lumber as well as the newer ACQ and copper azole lumbers.

Why doesn’t U.V. Plus for Hardwood Decks bead water?

Water beading is accomplished by adding waxes or paraffin to the stain. These additives do not last very long and are not good permanent water repellents, in addition to this they interfere with adhesion should you decide to paint over the stain. That’s why we don’t use them in our products. The high solids content of UV Plus fills the pores of the wood, providing excellent water repellency that will last.

I want a shiny finish. Can I put multiple coats of U.V. Plus for Hardwood Decks on the wood?

No. The only way to get a shiny surface on the wood is by using a multiple coat, film forming finish. We don’t recommend clear film forming finishes on decks because they are slippery when wet, they will eventually peel, and they are difficult to maintain and recoat. When properly applied, a penetrating finish like UV Plus for Hardwood Decks will not be shiny, it will have a natural, matte look.

I have trim or other wood surfaces that are made of cedar, pine, or pressure treated wood. Can I use the U.V. Plus for Hardwood Decks product on these other woods?

Yes, UV Plus for Hardwood Decks can be used on other types of exterior wood, including cedar, redwood, pine, and pressure treated lumber. Keep in mind that the appearance of dissimilar woods will not be the same after applying the UV Plus, but generally it is very complementary.

The weather report predicts rain tomorrow. Can I finish my deck today?

We wouldn’t recommend it. UV Plus needs at least 24-48 hours to dry in good conditions. If a newly stained deck is rained on, the rain can force the stain up out of the pores of the wood, leaving a blotchy appearance. It’s best to wait until there is no precipitation expected for 48 hours. In some regions, this may mean waiting for a different time of year to finish the deck.

Is U.V. Plus for Hardwood Decks suitable for vertical surfaces?

Yes, U.V. Plus for Hardwood Decks is an excellent choice for almost any exterior hardwood surface, including vertical surfaces.
