Dynaflex RPA (Rust Preventative Additive) is a water-based additive specifically designed to reduce rust and stain bleeds on asphalt, tennis, and basketball courts. Dynaflex RPA is added to the first coat of Dynaflex Acrylic Resurfacer. This additive does not thicken the mixture. Dynaflex RPA, when added to the first coat of Dynaflex Acrylic Resurfacer, will block rust stains and iron pyrites from discoloring the colored surface.
Reduces, and in some cases, eliminates active aggregate staining of asphalt covered with acrylic color coats.
Reduces rust spot bleed-through.
Requires No Additional Water
Unlike Most Additives.

(Based on 100 Gallons)
A minimum of 10% Dynaflex RPA added per 100 gallons of Dynaflex Acrylic Resurfacer will show significant improvement in the performance of the applied coating. Proceed to add 40% water based on the Dynaflex Acrylic Resurfacer. It is strongly recommended that 5-10 lbs. of silica sand be used
All sand used should be clean, dry pure silica sand, free of contaminants. Medium fine sand with an A.F.S. rating of 50 to 80 gives best results. There should be no more than 2% retained on 30 mesh or coarser, no more than 10% retained on 140 mesh and no more than 0.3% retained on 200 mesh.
For use over sound asphalt pavement, the following application procedures are recommended for best results:
One gallon of concentrate will cover 100 square feet. Multiply square yards of surface by .09 to determine gallons of concentrate per coat.
