Rapid-Set Crack Repair System

This stuff is Tough and Fast! If you do industrial or garage floors, Rapid-Set is a MUST HAVE. Rapid-Set allows you to quickly fill cracks and repair damage to create a flawless "canvas" for your flooring system.

For deep cracks or surface spalls, we recommend first filling the crack, joint or hole with clean dry sand. This will add compressive strength, reduce product usage and also make a more natural "concrete" appearance. After Rapid Set has hardened, it can be ground smooth, for a seamless repair. For flake, quartz or solid color interior floors, first install Rapid Set, then grind floor as normal.


Cleaning and Preparation Instructions

Clean the crack, joint or area to be repaired. The area must be completely dry prior to application. For best results, chase cracks with diamond blade. Clean the surface and remove all unsound concrete, dust and debris. Prepare surface using a twisted wire wheel for spalls. Cut perimeter of damage with dry diamond blade.

Before opening or handling Rapid Set, first put on proper protective equipment including eye protection and rubber gloves. Be sure to choose the formula that fits the temperature range in which the product will be installed.


Mixing Instructions

Mix ratio for Rapid Set is 1(PartA) : 1(PartB). Pour equal amounts of Part A and Part B into a clean, dry, easy dispensing container. Mix contents quickly, but thoroughly with paint stick. Improper or incomplete mixing may result in product failure. Install immediately after mixing. Product will harden in less than 2 minutes.


Application Instructions

Before application, always test product in an inconspicuous area to ensure appearance and compatibility are acceptable. Concrete should be fully cured for 28 days before applying Rapid Set. Do not use Rapid Set in joints between slabs intended to move or provide for flexibility. Always test for desired results before using on floors intended to be stained or dyed.

Immediately pour mixed product directly into crack or over sand in crack base. Work the repair area quickly. Screed to finished grade and allow to set. For better finished repair surface, pour mix slightly above the finished grade. Allow to harden, then grind flush. Work in circular motion to grind/smooth to finished grade. If floor is not intended to be sealed or coated, seal the repaired surface by brushing a thin coat of Rapid Set over the repaired area after grinding.

Coverage Rates will vary greatly depending on the depth and size of cracks.
