RIW Cementfill FC

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.
