Scrape or blow the crack clear. Surface must be clean, dry and sound. To do so, remove dirt, grease, bio-matter, wax and loose particles with the sponge and warm water. You may add a drop of dishwashing hand soap to the water. Wait until substrate appears dry before going to step two. NOTE: To prepare EPDM roofing materials, wipe down surface with lacquer thinner.


PhillyPutty® is a flexible, waterproof spackling paste made on-site as needed. Use it to fill and waterproof roof flashings, seams and cracks To make PhillyPutty®, mix our TrueGrit® aggregate into PerfectPrimer® until it thickensinto a paste thatwill“hang”or drip slightly on a trowelwithout being too stiff. APPLICATION: Spread“Putty”into the crack with a spackle blade or finger. NOTE: Hairline concrete cracks, aka pencil line cracks, may be repaired with PhillyPutty®, without requiring the Polytex® fabric.


Use the brush or ½” roller to apply PerfectPrimer® to the surface on an an area up to three feet long, and a bit wider than the fabric. Unroll Polytex® fabric into wet area. Then, working from the center out to the edges, brush the fabric until it is smooth. When fabric becomes tacky, apply a second coat. Finished repair is flexible and waterproof and can be coated over with your modified cement, mastic, epoxies, stucco, and paints, etc.


For corners, fold the fabric where you want to apply it. Cut a straight line into the fabric where it is folded over. Apply primer and lay the fabric flat down onto itself.


Typical cure time before skim coat is 12 hours. Keep open container out of direct sunlight. Product will dry faster on hot days and may be thinned slightly with water as needed. Product will not cure during continuous high humidity.


System is not designed for structural repairs. Do not use for negative side waterproofing such as interior foundation walls. Not for use in temperatures below 40 degrees F.


Clean up before product dries with water. After cure it may be removed from the skin using soap and warm water. Once cured it will not come out of fabrics, brushes, etc.


PerfectPrimer® will NOT adhere to silicone, silicone sealed surfaces or TPO. PVC must be cleaned first (do NOT sand) and wiped with isopropyl alcohol. PerfectPrimer® works with, but may have weaker bonds with vinyl polymer coatings. Always test primer with your coatings before applying them in the field.
