1. Can I paint or stain Wolmanized Residential Outdoor wood?
Yes, you can stain or paint Wolmanized wood. You can also coat this wood with a water repellent; in fact, we highly recommend it. The best way to tackle these jobs depends on the wood you have, its exposure, and the coating you plan to use. For detailed information, click here.
2. How long must you wait before the wood is dry internally?
The time it takes for wood to dry out depends on the climate and the wood's exposure. In summer in the American southwest, deck lumber open to sunshine can dry in a few days. In cool, damp weather or when shaded by an overhanging roof or tree, it will take much longer for wood to dry. As a fairly safe average, we recommend waiting six months before applying paint
3. What
maintenance is needed for the product?
No maintenance is needed to
renew resistance to fungi and termites. Wolmanized wood has a lifetime
limited warranty against these organisms. However, protection is required
to maintain the wood's appearance against weather. Sun and rain cycles
cause stresses in lumber and result in swelling, shrinking, warping, and
cracking.
• To help protect your project against moisture damage,
apply an effective brand of
water repellent as soon as your
outdoor wood project is finished or, for large projects,
as
sections are completed. Water repellent should be applied every year or
two.
• To revitalize a dingy appearance caused by dirt and mildew,
use deck brightener to clean
the outdoor wood.
To
validate the warranty in some states and for some species, apply an end-cut
solution.

5. Is Wolmanized Outdoor wood
safe?
A comprehensive study of occupational, residential, and
playground uses of wood pressure-treated with copper azole preservative has
concluded, "no adverse health effects are expected." Believed to be the
first independent human health risk assessment of the new generation of treated
wood products, the study was commissioned by Bayer Chemicals Corporation (now
Lanxess Corporation) and conducted by Gradient Corporation, a noted
environmental and toxicological consulting firm. Lanxess manufactures Preventol®
A8, which is an azole fungicide used in the copper azole preservative.
A number of different exposures (e.g., inhalation, incidental ingestion, exposure to the skin) were assessed and aggregated in each of these scenarios. The highest potential risk was estimated to be 17 times lower than the level that the EPA uses as a safety benchmark, thus demonstrating the safety of copper azole-treated wood.

6. How is
Wolmanized Outdoor wood produced?
Wolmanized® wood is made in a
pressurized cylinder using a closed system that recycles excess preservative for
future use and releases no air pollutants nor wastewater. Only licensed
producers who follow stringent quality control measures make Wolmanized
wood. The basic treating process is simple and highly controlled.
| 1 — Lumber, timbers, or plywood is loaded onto small rail or tram
cars. The trams are moved into a large, horizontal treating cylinder. |
| 2 — The cylinder door is sealed and a vacuum is applied to remove
air from the cylinder and the wood cells. |
| 3 — Preservative solution is then pumped into the cylinder. |
| 4 — The pressure is raised to about 150 pounds per square
inch, forcing the preservative into the wood. Treating time varies depending on species of wood, commodity being treated, and the amount of preservative to be impregnated. |
| 5 — At the end of the process, excess treating solution is pumped
out of the cylinder and back to a storage tank for later re-use. |
| 6 — A final vacuum removes excess preservative from wood
cells. The cylinder door is opened and
the trams are pulled out. The wood is wet, so it is kept on a concrete pad until any dripping ceases. |

to Top7. Does
Wolmanized Outdoor wood come with a water repellent?
A compatible
water repellent additive to provide built-in moisture protection is available in
some areas. (Also, Thompsonized® Wood is high grade material that has
factory-applied waterproofer. For more information, click
here.)
8. What are the environmental
benefits of Wolmanized Outdoor wood?
Unlike plastics, steel, and
concrete, Wolmanized wood is made from a renewable resource grown on managed
timberlands. It requires less energy to produce than plastics and offers greater
insulation value; and, because of its lighter weight, preserved wood can often
be installed with lighter equipment which has less environmental impact.
Wood products reduce greenhouse gasses, and preservative treatment extends their
service life. For more information, click

9. Do you offer building plans for decks and outdoor
projects?
Yes. See the Homeowner
section for detailed information on building a deck, as well as
building plans for many popular backyard projects. Also, see deck
building tips. Back

10. What are the
strength properties of Wolmanized Outdoor wood?
This wood has
the same strength properties of untreated wood of the same species, grade, and
moisture content.
11. What hardware is recommended for
Wolmanized Outdoor wood?

12. How do I dispose of
Wolmanized Outdoor wood waste?
Wolmanized wood waste, such as
scraps, broken boards, and sawdust, can be disposed of with ordinary trash
collection. Neither the wood nor the preservative residues are considered
hazardous wastes. If a particular landfill has restrictions
against traditional treated wood, it may accept Wolmanized Outdoor wood.
Treated sawdust and shavings are not recommended for composting,
mulching, or animal bedding, and the wood should not be burned except in
approved commercial incinerators.
