What is Messmer’s U.V. Plus?

UV Plus is a penetrating deck stain, wood stain and oil finish that beautifies and protects exterior wood, providing a natural appearance. It is ideal for use on cedar, pine and redwood and comes in a variety of tones and semi-transparent colors. UV Plus contains fungicides and UV absorbers of the highest quality. It does not form a surface film when properly applied and is not subject to peeling and flaking. To recoat, just clean and/or brighten the wood surface and reapply UV Plus. No stripping or sanding is necessary.

How long will it last?

On vertical, smooth surfaces, UV Plus can be expected to last for 2-3 years, on rough surfaces, 3-4 years and on decks 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. We suggest using our transparent finish that is designed for the type of wood, such as Natural Redwood for redwood, Natural Cedar for cedar, and Pine/Fir for pine or douglas fir. This allows you to maintain a natural look and provide extended color retention and protection to the wood.

After I applied UV Plus, 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 UV Plus?

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 UV Plus 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.

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.
