A single component, thixotropic, polymer modified, cementitious repair mortar with high adhesive properties.
Features and benefits:
- RIW Cementfill FC incorporates the most advanced microsilica, polymer and fibre technology, curing to provide high waterproofing properties, excellent protection from acid gases, chlorides and freeze/ thaw cycles as well as enhanced chemical resistance.
- The product is supplied ready for onsite mixing and use, requiring only the addition of clean water.
- Dense matrix offers low permeability to water, even at 10 bar pressure.
- Incorporates the latest proven cement chemistry, microsilica, fibre and styrene acrylic copolymer technology.
- Non-toxic when cured.
- Can be applied by palette knife, wood or steel float, and ’bag rubbing’ techniques or spray.
- CE marked.
Substrate:
- The areas to be treated must be free from all unsound material, i.e. dust, oil, grease, corrosion by-products and organic growth.
- Smooth surfaces should be cleaned to remove release agents, curing compounds and surface laitance, preferably using wet grit or water blasting techniques or equivalent approved methods. The concrete sub-base should be a minimum of 20 N/ mm².
- The product is highly polymer modified and as a result concrete surfaces do not generally require a primer.
- Highly porous substrates should be primed with RIW Cementseal Primer.
Application rate:
- Normal applications: 2.2–2.6 litres of clean water per 20 kg bag, depending upon desired consistency.
- Screeding applications: 2.4 litres of clean water per 20 kg bag.
Application temperature:
5–35°C.
Curing:
Protect the mortar from strong sunlight and drying winds with RIW Cementseal Primer, polythene sheeting, damp hessian or similar.
