RECOMMENDED APPLICATION INSTRUCTIONS ON A ROOF

2. Use a 3 – 4 foot arc pattern.

3. Allow Safe-T-Kote Rinseable Primer to stand for a minimum of 15 minutes.

4. Clean EPDM with a commercial power washer (between 2000-3500 psi). When cleaning the EPDM, it should be done slowly and close to surface in order to remove mica and inorganic release agents.

5. Rinse thoroughly with power washer. The rinse step may be done at a faster pace than the cleaning step. The final rinse water should be clear with no soap bubbles present.

6. The EPDM will range from muddy brown to black after washing with Safe-T-Kote Rinseable Primer

7. When the surface is dry, coating can begin.

SAFE HANDLING INFORMATION, PRECAUTIONS:

1. Thoroughly read MSDS for product – It is important to note that Section 13 of the MSDS titled “Disposal Considerations” discusses spills of undiluted Safe-T-Kote Rinseable Primer. These undiluted spills are different from the rinsate referred to below in the technical notes. The rinsate is defined in these notes as the roof washings composed of diluted Safe-T-Kote Rinseable Primer that result from the proper use of the product according to the application guidelines. In general, during the pressure washing of a roof, one part of Safe-T-Kote Rinseable Primer is diluted with 300 parts of water.

2. Ensure proper drainage:

We recommend the use of prudent judgment regarding the release of roof rinsate containing Safe-T-Kote Rinseable Primer into the environment. Based on aquatic toxicity data, this primer is classified as of LOW CONCERN to aquatic invertebrates and fish, according to the USEPA TSCA classification criteria, i.e., the LC/EC50 > 100 mg/L.

The results indicate that the lethal or effective (functional) concentration affecting 50% of the tested population is greater than 220 mg/L of Safe-T-Kote Rinseable Primer for fish, and aquatic invertebrates. Safe-T-Kote Rinseable Primer is classified as of moderate concern to algae according to USEPA TSCA classification criteria, i.e. the LC/EC50 is between 1 mg/L and 100 mg/L. Dilution of the primer with rinsate and subsequent added dilutionary capacity of receiving streams, rivers or ponds would likely buffer any potential for adverse effects.

Because of the low toxicity of the formulation to fish, aquatic invertebrates and algae it is unlikely that releases of the diluted Safe-T-Kote Rinseable Primer material into a storm sewer will cause adverse impact to exposed organisms. The numbers and diversity of organisms in these non-natural systems are anticipated to be low. Increased dilutionary capacity of any receiving water body will serve to further mitigate any potential for adverse effects. Without detailed plans regarding the receiving water course at the site in question, caution should be exercised. Release of rinsate into pristine or near pristine water courses should be avoided.

Note that compliance with local regulatory ordinances regarding releases of the rinsate into the aquatic or soil compartments should be ensured prior to any disposal operation.
