Application Instruction of PondPro2000 by webmaster epdmliner
Pond Pro is a liquid version of EPDM very similar to EPDM pond liners sold in pond supply stores. It works extremely well on all non-porous concrete fountains as well as EPDM fishponds liners. Reflecting pools are another good application for EPDM. These are demanding applications where the unique properties of EPDM have a distinct advantage over other products. The success of PondPro 2000 is through combining ethylene and propylene with a diene monomer. PondPro 2000 is safe for fish and plant life as well as chlorinated water. This polymer (when crosslinked) is an excellent moisture barrier, resistant to oxidation and UV degradation but its most important property is its ability to tolerate both low as well as high temperatures (from minus 62 to plus 350 degrees Fahrenheit). General EPDM rubber is used exclusively for radiator hoses, freezer gaskets and low temperature seals, steam hoses, and rubber roofing membranes. It is also blended with other rubbers to improve their properties. A multitude of products are now better and last longer because of the contribution made by EPDM rubber.
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 PondPro 2000
Asphalt based aluminum 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, finish with a short nap roll to press air out of cracks and even out wet film. Product 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:
PondPro2000 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.
Author wants to minimize the problem of pond leaks in this article. So he defines many tricks and methods to solve this problem. He also provides some guidelines that how we can utilize our pond repair resources and how we can reduce our expenditures in ponds by using EPDM Liner, Fish Ponds, Pond Repair and other modern techniques.
