VELOSIT® RM 224
Vertical and Overhead Finishing Mortar
Product Description
VELOSIT RM 224 is a cementitious finishing mortar for various types of construction substrates. It creates a very fine surface texture and is especially suitable for fair-faced concrete.
VELOSIT RM 224 is a shrinkage compensated cementitious finish mortar with fast strength development.
VELOSIT RM 224 is the result of many years in the field testing and research. VELOSIT RM 224 creates an extremely well bonded, rigid, abrasion resistant layer on the substrate.
Typical Applications
- Finishing of surface defects on concrete, masonry and many natural stones
- Application on horizontal and vertical incl. overhead areas
- Filling of blow holes, honeycombs and surface roughness
- As a finish on concrete repair systems
- Application thickness from feather-edge to 10 mm
Features
- Minimal shrinkage/expansion under dry resp. wet curing conditions minimising the risk of micro-cracking
- Excellent workability especially overhead
- 30 min. working time and 15 MPa compressive strength after 4 hours
- Final strength of more than 35 MPa after 28 days
- Open to foot traffic after 2 – 3 hours
- Very good adhesion to properly prepared concrete and masonry
- Water curing only under hot and dry conditions required for max. 4 hours
- Good resistance against CO2 and Chloride penetration due to a very tight pore structure
- Good weathering resistance
- Good sulfate resistance
