    Preparation & Application
    Surface Preparation: Surfaces should be clean, dry and free of all loose material. Wire brushing or sweeping is generally sufficient. If needed, wash with Bio-D®, or a suitable degreaser or detergent solution, to remove grease and oil. Rinse and allow to dry.

    Priming: A primer is not usually required if patch or crack repairing. Tack Coat adhesive primer is recommended when applying Concrex® Rapid Set as a thin section screed or when applying to smooth, non-porous or metal surfaces.

    Mixing: Concrex® Rapid Set should be stored at an ambient temperature above 50°F for approximately 8 hours prior to use. Do not use material if air and surface temperatures are below 50°F. Each pack of Concrex® Rapid Set contains aggregate pre-blended with resin and the curing agent. Do not mix inside the plastic bucket. Wearing protective gloves, tip the aggregate on to a mixing tray or board. Shake the containers of curing agent thoroughly until the liquid is a uniform color. Form the aggregate into a mound and leave a small hole in the middle. Empty the curing agent into the hole, ensuring the container is completely drained. Carefully mix the aggregate with the curing agent using a trowel until a smooth mortar is obtained, this will take several minutes. The more thorough the mixing, the ‘wetter’, smoother and more manageable the mix becomes. Alternatively, you can knead the mixture by hand, but you must wear suitable gloves. It is important to mix thoroughly until you achieve a consistent color.

    Application: Place mixed material into the area to be repaired and spread out and finish with a steel trowel. To reduce ‘drag’ on the trowel, wet the blade with mineral spirits. This will aid getting a smooth finish to the Concrex® Rapid Set. Concrex Rapid Set is normally applied in thicknesses of ¼ to 2", but repairs can be feather-edged for a neat finish, as long as the majority of the repair is at least a ¼" thick. For repairs deeper than 2", apply in separate layers (allow 6-8 hours between layers for curing) or use Concrex® Deep Fill (which can be applied 1/2 to 4 inches thick in one layer). There is no need to reapply Tack Coat if building up in layers.

    COVERAGE: Approximately 12 sq. ft. per 20 lb. kit at 1/4" thick.
