RIW Cementfill FC

Features:

• 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.

Usage:

• A fully waterproof, engineering quality fairing coat for filling minor blow holes and defects, and for repairing surface cavities and honeycombed concrete.

• Thin screed applications can be used to waterproof and/ or level vertical, horizontal and overhead concrete surfaces.

• Suitable for feather edging.
