TCS Concrete Repair Kit

TCS Concrete Repair is a two component, low odor, liquid applied polyurethane alloy system for repairing concrete and masonry substrates. It is supplied as a 2 gallon kit. Where a patching compound just fills a hole, this rebuilds a surface and leaves a new one behind that protects the concrete underneath from weather, corrosion, erosion, freeze thaw spalling and chemical attack.

That protective function is what makes it worth the money on exterior and exposed work. Freeze thaw spalling is a cycle, not an event. Water gets into the surface, freezes, expands, breaks off a layer, and the fresh face it exposes absorbs more water than the old one did. A repair that only fills the damage leaves the cycle running. A liquid applied polyurethane alloy surface interrupts it.

In system position this is substrate repair, so it happens before the coating system, not as part of it. The normal sequence on a damaged slab is prep, then repair the spalls and defects, then prime or apply the vapor barrier if the slab needs one, then base coat, then broadcast, then topcoat. Confirm that whatever coating you are running is compatible with a polyurethane repair surface and knows how to bond to it before you build over the patched area.

Low odor matters here because repair work often happens in occupied buildings, loading docks and interior spaces where the rest of the operation is still running. Mix ratio, coverage, working time and cure schedule are on the technical data sheet, available on request. Call 817-676-6793 for the sheet or to talk through a specific repair before you order.
