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.
To Disinfect
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 alleviated.
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).
Safety precautions
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 ceiling.
Infants and other family members suffering from asthma, allergies or other health problems should not be in the work area or adjacent room during the cleaning.
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 as possible.
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 the edges.
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.
