FLEXKIT – Stair Repair
Stairs are a costly item to replace, so repairing them is definitely the way to go. The problem is that up to this point, you could only patch them. FLEXKIT has changed this; you can now actually repair stairs. In the past, the materials used to patch large chips like these would expand and contract at different rates than the concrete they were patching, caused by temperature changes. This constant movement between the two different materials would eventually cause the bond between the two to fail and the patch material would “pop out.” No more. FLEXKIT, with its ability to expand and compress, will absorb this movement, and with its unique bonding capabilities, will not “pop out.” In addition, the fact that it cures to 12,000 psi makes the patch stronger than the structure itself. This is a true repair, not a temporary patch.
Using a chip brush, the damaged areas were primed using flexPRIME. Once the prime coat became tacky (like duct tape), a batch of FLEXKIT was prepared using 1 part FLEXKIT, 1 part sand and 2 parts fumed silica. This mixture was applied using two trowels, placing one on the face of the rise and one on the top of the run. Once the mixture hardened (less than an hour), a grinder was used to smooth out any imperfections, tape was applied and the stairs were painted and placed back into service in less than two hours.
Remember, “Fix It with FLEXKIT and Forget About It.”
Best of Success,
