1. Substrate preparation: The substrate must be prepared with sand blasting, shot blasting, or high-pressure water blasting to remove all bond-breaking substances. Remove all carbonated concrete. Test with Phenolphthalein or other suitable indicator until concrete with sufficient alkalinity for rebar protection is reached. If rebar is exposed, remove concrete at least 1/4” (6mm) behind rebar to fully embed the steel into VELOSIT RM 211. Substrate must be rough, open porous, and load-bearing
2. Mixing: Mix VELOSIT RM 211 with 17 -20% potable water, i.e. 1.1 – 1.3 gal (4.3-5 l) water per 55 lb (25 kg) bag. Fill 17% mixing water (1.1 gal per bag) into a suitable bucket and mix the powder with a slow speed drill (300-600 rpm) into the water until a lump-free mix is achieved. Add more water under stirring to adjust desired consistency. The product is workable for 45 min. at 70°F
3. Trowel application: Apply a slurry coat of VELOSIT RM 211 by scrubbing material with a wet sponge into the concrete surface. Trowel VELOSIT RM 211 fresh in fresh into the slurry coat. The product can be applied up to 6”. Make sure to work in sections that can be finished within 30 min. Rebars and other penetrations must be fully embedded into the mortar
4. Spray application: Use suitable spray machines such as Inotec GmbH: INOMAT-M8. In mixing pumps feed the powder into the product hopper and adjust the water to the desired consistency. With mortar pumps add the mixed product as described above into the feed hopper of the spray machine and spray continuously. If a smooth surface is required, follow with a trowel shortly after material is sprayed. Work in sections. Long spray interruptions may result in clogging of the spray hose. The product may cure a lot faster if the hose is exposed to direct sunlight. Always empty and flush the machine after spraying or before long spray interruptions. VELOSIT RM 211 is a fast-curing material and may be hard to remove if left in the machine
5. Curing: VELOSIT RM 211 does not require long-term curing as it reacts relatively quickly with water. Only under hot weather or very dry conditions water curing for 3-4 hours is required.
What is the final strength of VELOSIT RM 211 after 28 days?
The final strength of VELOSIT RM 211 after 28 days is more than 5800 psi (40 MPa).
How long does it take for VELOSIT RM 211 to be open to foot traffic?
According to the context, VELOSIT RM 211 is open to foot traffic after 3-4 hours.
What are the applications of VELOSIT RM 211?
The typical application fields for VELOSIT RM 211 are the repair of surface defects on concrete, overlays and repairs on concrete structures like dams, bridges, beams, balconies, facades, filling of blow holes, honeycombs and surface roughness, and application thickness from feather-edge to 6”.
