Always read directions fully before applying any product. The directions
contained in this document do NOT supersede the label issued and registered
with the US Environmental Protection Agency (EPA). For up-to-date information
on UrthPRO please visit www.epa.gov.
UrthPRO can be applied by saturated cloth, trigger spray bottle, pump-up
sprayer or other spray-applicator. A foaming spray is recommended, but not
required. Do not fog.
UrthPRO can be used full strength to remove soils and stains, including those
caused by mold infestation. To clean, apply UrthPRO to the affected area and
scrub with a cloth or brush suitable to the durability of the surface. For deep-set
stains, a second application may be necessary.
Apply UrthPRO directly to the affected surface until wet, let stand for 5 minutes
and wipe with wet sponge or cloth suitable to the durability of the surface.
UrthPRO must come in direct contact with bacteria, mold, fungi and other
microorganisms to be effective.
Small area mold clean-up
Small areas of mold (less than 3 patches of 10 square feet or less each) can
easily be treated by anyone. You should always wear protective equipment
when cleaning mold, which should at minimum include:
safety glasses or goggles;
a disposable dust mask (3M 8210 or equivalent); and
household rubber gloves.
Infants and other family members with asthma, allergies or other health problems
should not be in the work area or adjacent room until the mold problem has been
To Clean & Disinfect Small Areas of Washable surfaces:
Scrub with UrthPRO and allow to stand for 5 minutes. Wipe with a damp cloth
if cosmetically necessary and dry quickly.
Moderate area mold clean-up
If you follow the proper procedures and use the proper protective equipment, a
do-it-yourselfer can easily clean up moderate areas of mold. Moderate means
more than 3 patches of mold, each smaller than 10 square feet, or one or more
isolated patches larger than 10 square feet but a total area smaller than 32
square feet (size of a 4 x 8 foot sheet of plywood or drywall).
Wear a disposable dust mask (for example, 3M 8210 or equivalent),
glasses or safety goggles and household rubber gloves.
Isolate the area to be cleaned with plastic sheeting, taped to walls and
Infants and other family members suffering from asthma, allergies or other
health problems should not be in the work area or adjacent room during
A small clean up should take minutes (not hours) to finish. When the clean up
takes hours to a day to finish, it is suggested that you upgrade to a better filter,
such as a half-face respirator with charcoal cartridges. An exhaust fan installed in
a window in the room being cleaned may help prevent contamination of other
areas of the structure as well as provide ventilation.
For Moderate Area General cleaning
Vacuum surfaces with a vacuum cleaner which has a High Efficiency Particulate
Air (HEPA) filter or is externally exhausted. Scrub or brush the moldy area with
UrthPRO. Rinse by sponging with a clean, wet rag. Repeat as necessary. Dry quickly. HEPA vacuum the surfaces that were cleaned as well
as surrounding areas.
Vacuum loose mold from wood surfaces using a HEPA or externally exhausted
vacuum. Clean the surface of the wood with UrthPROTM. If the staining does
not come off, wet the surface with UrthPROTM, then sand and vacuum thesurface of the wood with a vacuum/sander combination. It is important to
vacuum at the same time to prevent mold spores from being dispersed into the
air. Clean the surface of the wood with UrthPRO and rinse with a clean damp
rag and dry quickly. Note that wood affected by rot may need to be replaced.
Cleaning Moderate Area Concrete
Vacuum the concrete surfaces to be cleaned with a HEPA or externally
exhausted vacuum cleaner. Clean up surfaces with UrthPRO. If the surfaces
are still visibly moldy, saturate the moldy concrete surface with UrthPRO using
a brush, sponge or rag. Keep the surface wet for 5 minutes. Rinse and agitate
(brush) the concrete surface twice with clean water. Dry thoroughly, as quickly
The paper facings of gypsum wallboard (drywall) grow mold when they get wet or
repeatedly wet and dont dry quickly. Cleaning with water containing detergent
not only adds moisture to the paper but also can eventually damage the facing. If
the mold is located only on top of the painted surface, remove it by cleaning with
UrthPRO (see above). If the mold is underneath the paint, the moldy patch
and other moldy material behind it are best cut out and the surrounding areas
should be cleaned with UrthPRO. New materials may become moldy if the
moisture entry has not been stopped. If this is the case, replacement of the
materials should be deferred until the source of the moisture is corrected. The
affected areas should be temporarily covered with plastic sheeting and sealed at
Any areas that show new patches of mold should be cleaned promptly.
NOTE: If your problem is greater than those discussed here, you encounter a
persisting problem or see adverse health effects afflicting family members inside
your home, it is advisable to consult an indoor air quality expert.
