Spartacote Fast Fix is a fast-setting, two-component hybrid urethane repair material with an ultra-low viscosity to allow for deep penetration into concrete and compressive strengths of over 4200 psi, according to the company.

Fast Fix can be applied neat to fill hairline cracks or nail holes, or mixed with kiln sand to create a slurry mixture that can be used to fill in deeper cracks and other areas. Typical applications include residential garage floors, basements and retail floors.
