MG-Krete with Activator

Mg-Krete with Activator. 1260 MG-KRETE™ is an inexpensive, two component, high early strength structural repair material that is very easy to use in the field.  Sold as a set; also available separately.


1260 MG-KRETE™ is used for all types of concrete repairs. It is used for patching, from shallow feathering to deep pours. It can be poured into forms, it can be trowelled vertically and overhead, it can fill large cracks or be used as a fast set plug.

Features and Benefits

  • Cures very rapidly in all weather at all temperatures to form a very hard, tenaciously bonded repair.
  • Non-flammable and has high heat resistance.
  • Cures very rapidly, most applications can be returned to service in 30 minutes.
  • Does not shrink on cure.
  • Stronger than concrete within 45 minutes.
  • Self-priming and will bond to virtually any construction material.
  • Very easy to use, there are no specific slump requirements, no critical mixing ratios, no sophisticated and expensive surface preparation.
  • Non-toxic, it contains no harmful chemicals, and it cleans-up with water.
  • Very cost effective, it has the performance characteristics of the best polymers at a fraction of the cost.
  • Totally waterproof, it is resistant to oils, gasoline, salt and UV radiation.
  • Approved by Agriculture Canada for incidental food contact


Keep all materials dry, DO NOT ADD WATER TO THE MIX. Maintaining the mix ratio as supplied, i.e. one container of liquid activator to one bag of dry component, will give a trowellable consistency suitable for most floor applications, however the slump may be adjusted to the applicator's preference or to suit the specific job conditions by increasing either of the two components. DO NOT ADJUST THE SLUMP BY THE ADDITION OF WATER. Mix the two components by mechanical means until all the material is wetted, and place quickly. Dry pea gravel may be added to the mix to increase the yield on deep placements.

Application Instructions

Surface must be clean, dry and free of loose material. Remove all dirt from area to be covered leaving a rough, clean surface. For applications at ambient temperatures below 50ºF (10ºC) 1261 LOW TEMP ACCELERATOR must be used to ensure a full cure. With temperatures above 68ºF (20ºC) the 1263 HIGH TEMPERATURE RETARDER can be used to extend the working time. Do not pre-wet surface. Keep an adequate supply of water on hand to keep equipment clean. Thoroughly dry all equipment before using 1260 MG-KRETE™.
