Surface preparation
Surface to be coated should be clean, dry and structurally sound. Fasten loose areas with adhesive (contact cement) or pop rivets. Oil or wax must be completely removed with solvent. Remove loose portions of existing coatings and brittle caulk with scraper and wire brush. Whatever still has good adhesion may remain to be recoated. Rusty or pitted metal should be wire brushed to remove loose oxide. Tightly adhering corrosion may be directly coated with PondPro2000.
Asphalt based aluminium coatings should be removed as much as possible by wire brush or abrasive disc. Roof cements should be removed and replaced with butyl caulk where necessary. Repair torn rubber with adhesive Butyl Tape. A rubber patch may be applied over torn area if desired. Remove chalk from white rubber membrane by brushing with a detergent solution followed by a water rinse or working surface with a stiff brush. Smooth metal or plastic surfaces should be roughed up to improve adhesion of Pondpro 2000. A deglossing solvent may work on some plastics.
Coverage:
Pondpro 2000 will cover up to 10 square feet per quart on a very smooth surface. The required 20 mil film thickness will be achieved when the above spreading rate is used. If you are uncertain how to calculate the amount of material you will need, please contact EPDM Coatings at (610-298-1949) M-F 9:00.am-5:30 EST.
Mixing Directions:
The container is under filled to allow for the addition of the pre-measured catalyst that is included. A drill and a mixer (shown below) will be needed to incorporate the catalyst. For a quartn can a short mixer will suffice.
Mix rubber material in can/pail until uniform; center mixer shaft in pail or can and begin mixing until a vortex is formed. Slowly pour all of catalyst into vortex. Move mixer up and down and in a circular motion for 2-3 minutes until all portions of can/pail are uniformly mixed
Application:
By brush, roller or squeegee. A combination of methods might be most effective. For example, on a flat roof, pour a serpentine bead of material, distribute with squeegee, and finish with a short nap roll to press air out of cracks and even out wet film. Products will self level when sufficient material has been applied. Working time is 4-6 hours depending on temperature. A single application of Pondpro 2000 is preferable to multiple coats. Apply with brush around flashings and edges using long, slow strokes. On flat surfaces, material can be poured, spread with a squeegee and then evened out with a short nap roller. Touch-ups may be applied as desired after initial film has cured and surface is first wiped with solvent.
Temperature and Cure Conditions:
Pondpro 2000 may be applied at any temperature that permits it being spread onto the surface. It will waterproof immediately upon application. The solvent will evaporate at a rate governed by temperature but will not be affected by relative humidity. Exposure to freezing temperatures before cure has taken place will not damage the film. The time necessary to reach cure should not be a concern as this process will occur automatically. Exposure to sunlight will accelerate the curing process. The final film properties of the cured membrane will be the same regardless of the time required to achieve cure. Pondpro 2000 will provide long term protection even under extreme exposure conditions. Once you have completed the application it is suggested to wait 7 days assuming your day temps have been above 55 degrees before you fill the pond with water.
