Fast-setting Crack Filler for Concrete FASTPATCH CR (Crack Repair) is a rapid setting two-part polyurethane designed for concrete repair. It is designed for damaged concrete surfaces where cracks, spalls and edge breaks must be filled in to extend the life of the concrete. Its combination of fast set, high strength and low viscosity make it ideal for areas which must be brought to level. It may be left uncoated after cure, or standard concrete coatings may be applied over it. WHERE TO USE FASTPATCH CR Floors – Cracked or spalled concrete Joints – Broken corners and edges Before Coating – Accepts most concrete primers Low Temperature Applications – Cures on cold substrates FEATURES AND BENEFITS Superior Adhesion-tight bond to substrate without primer Very Low Viscosity-penetrates and levels on surfaces Sets in Minutes-rapid return to service Toughness-does not become brittle with age Ease of Application-can be static mixed or manually applied Cures at Low Temperatures – Year round use FASTPATCH CR is: Low Viscosity Polyurethane Self Leveling – Gel time 2-4 minutes at 70°F (21°C) Set Time 5-20 minutes (temperature dependent) Low temperature repair Superior adhesion strength Low moisture sensitivity Fast-setting Crack Filler for Concrete FASTPATCH CR (Crack Repair) is a rapid setting two-part polyurethane designed for concrete repair.
