Use of Impregnon - A Mold inhibitor
These instructions are recommended treatment methods taken from the manufacturer of Impregnon. They are helpful in minimizing mold exposure for the mold sensitive individual. Please note that Impregnon and many other fungistatic agents may cause skin sensitivity after exposure to direct sunlight. It is mandatory that you thoroughly wash your hands when finished with the applications.

Here is how you can treat the following areas that support mold growth in the home. These maneuvers will help hayfever and asthma symptoms in mold sensitive individuals.

FILTERS: Your furnace and air conditioning filters (They are the same if you have a central unit) catch mold spores that enter your home from the outside. If treated, mold has less chance of growing there and hen being blown into the bedroom, den or throughout the house. Treat each filter once each time it is replaced. TREATMENT: add one teaspoonful of Impregnon to 6 ounces of water and spray them from a windex-type bottle of flit-gun container (available at most hardware stores) on both sides. Wet the filter thoroughly and then allow to dry before placing in the furnace.

WALLS: When painting walls in the home, use a water base paint (Latex or Bondex) Impregnon cannot be mixed with an enamel or an oil based paint. TREATMENT: add 2 teaspoonfuls of Impregnon to each gallon of paint and mix well. Apply where needed. If a room is papered, mix Impregnon into the paste (tell your paperhanger to do it) and mix 2 teaspoonful/gallon and apply.

FLOORS: If floors are to be painted, certain type paints should not be used as mentioned above such as enamel. TREATMENT: add 1 teaspoonful of Impregnon for each gallon of water used and then soap or detergent (do not use bleach) Mop and allow to dry. Repeat each time floors are mopped.

PLANTS: Mold often grows in the soil nourishing your greenery and its growth can be slowed down.

TREATMENT: add 1 teaspoonful of Impregnon to a gallon of water and water the plants in the usually manner. You may use the same water and repeat three of four times when plants require it. Impregnon will not affect your plants.

FABRICS: Many washable fabrics (clothing, draperies, bedding, hose, etc) may be treated win the laundry cycle. TREATMENT: Add fabrics while dry to your washing machine containing one teaspoon of Impregnon for each gallon of water used, after soap or detergent has been added. Keep water volume low and launder for 3 or 4 minutes. Then the normal amount of water can be added along with bleach, if necessary. Do not add bleach before the Impregnon has done its job.

BATHROOMS: You may notice a black growth of mold around the tub area and the shower curtains. Launder shower curtain and allow to dry. Scrub any mold with mold removal solution. TREATMENT: add 1 teaspoonful of Impregnon to a gallon of water and immerse shower curtain while dry. Wring it out and allow to dry. For tub area, use dilution as with Flit-gun (noted under filters) and spray all the areas and allow to dry. Repeat once a week.

HUMIDIFIERS, VAPORIZERS, DEHUMIDIFIERS, AEROSOL NEBULIZER UNITS: Any of these appliances can harbor mold and allow its growth during extended usage. TREATMENT: add 1 teaspoonful of Impregnon per gallon of water, and for humidifiers a teaspoonful for each gallon of water to be collected. For aerosol nebulizer units, plastic tubes should be rinsed with Impregnon solution ( 1 teaspoonful per 6 ounces water) Allow to dry before reusing.

RUGS: The greatest source of mold in your home is wall to wall carpeting. Is it necessary to treat both the pad and the rug. Impregnon will not damage or discolor your rugs. TREATMENT: Use a canister-type tank where pumping pressure can spray its contents, add 2 teaspoonfuls of Impregnon per gallon of water. Dampen the pad on one side and allow to dry. Repeat for the other side (don’t soak it). When dry, place the rug atop it and dampen it likewise and allow to dry. Repeat during the spring and warmer months when molds grow.

OTHER USES: You may spray boats (inside cabin area), closets, lockers, books, shoes, (inside to prevent mold growth) and leather goods that seem to be a safe haven for mold growth. TREATMENT: Using a Flit-Gun dilution as with filters, spray the area thoroughly and allow to dry. May be repeated monthly during the warm months.
