Areas of Application
- Industrial concrete floors
- Parking decks
- RCC members
Method of Application
Surface preparation
- Remove all oil, grease, dirt, debris and loose materials by using mechanical tools like chisel, wire brush, scabbler, shot blast or sand blast.
- Profiling of the floor is essential. Cut the floor to get rectangle shape and sufficient depth for filling. Under no circumstances depth of filling
should not be less that 12 mm. Edges can be cut to an angle less than 90 degree for better results.
- All the construction joints, expansion joints can be retained as it is or modified based on the requirement.
Bonding agent
- Cement slurry modified with Dr. Fixit Pidicrete MPB can be used as a bonding coat.(1:1 proportion)
Mixing
- Take the required amount of water in a mixer and then add the powder; mix for 3-5 mins with a drill mixer (for small job) or a paddle type mortar
mixer (for large job) until a smooth lump free mix is obtained.
Placing
- Place the mixed material on the repair area immediately when the bond coat is tacky with a trowel to a required thickness.
- If the thickness is more than 25 mm, same should be filled in two layers with a bond coat. The area of a patch should be restricted to 2 sqm.
- For a large application area, it should be divided into small areas of 1.5 to 2 sqm and then filled.
- Allow final layer to set for 24 hours and cure with water (light curing) for 3 days. Alternatively Dr. Fixit Curing Compound can also be
applied after 4 to 5 hours of casting.
- Light traffic can be allowed after 24 hours
Precautions & Limitations
- Do not undertake application for areas more than 1.5 to 2 sqm at a time
- Adequate care must be taken for construction / expansion joints
- Should not be applied in less than 12 mm thick sections
- For best results a bond coat of Dr. Fixit Pidicrete MPB is recommended
- Not for floors requiring acid / alkali resistance
- Not for concrete roads repair
