Project Instructions

RAZON COLDCRETE-27 Can be applied from freezing temperatures to upto 45 Degrees Celcius and where humidity is <85% for atleast 30 minutes.

Step 1
Surface Preparation:

  • Rigorously clean old concrete with mechanical equipment like a wire brush or better if you use a grinder with wire brush wheel to ensure proper adhesion of the new surface to the old concrete.
    NOTE: use only RAZON GOLDY CLEAN high performance soap to remove any dirt, oil, grease or deteriorating concrete.
  • In such a manner prepare the deeply spalled areas like potholes, and further repair large cracks with RAZON Super EPB 525.

Step 2
Mix the RAZON COLDCRETE-27 using a bucket and a paddle mixer attachment on a drill machine (hand mixing and standard concrete barrel-type mixers cannot be used for this application).

Step 3
Using the candle water heater, warm water to approx 40-45 Degrees Celcius in a bucket. Measure and add 3-3.5 litres of warm potable water approx 43 Degrees Celcius to a bucket to mix one 30-kg bag of RAZON COLDCRETE-27 (the powder should be poured into the mixing water).

Step 4
Mix for about 60 seconds until a lump-free pourable consistency is achieved. If the mix is too thick, add water sparingly to reach the consistency of syrup; if the mix is too thin, additional powder can be added.

Step 5
Pour the RAZON COLDCRETE-27 onto the prepared pothole/ abraded concrete surface.

Step 6
Using the finishing tool, evenly spread the RAZON COLDCRETE-27 back and forth onto the slab to match the surface level of the adjoining concrete.

Step 7
Allow traffic over the area between 6-8 hours of mixing and placing. NO CURING REQUIRED
