High Strength Newton HydroCoat 203 Repair Mortar for Reparation of Concrete - Rapid Set & High Strength Repair Mortar

Polymer-modified, and fibre-reinforced, HydroCoat 203-RM is physically and chemically compatible with the host concrete, quickly exhibiting high adhesive and compressive strength. As a single component, requiring only the addition of water, the resulting mortar is rapid curing with enhanced polymeric properties and reliable strength development which is not significantly affected by low-temperature use.

The mortar can be used as supplied up to 100 mm deep, or it can be bulked out with sharp sand to form a high-performance screed or for floor or deck repairs up to maximum depth of 300 mm.

Surface preparation is required, as is protection after application - consult manufacturer for details.

Features and benefits:

• Incorporates the latest proven cement chemistry, fibre and styrene acrylic copolymer technology.
• Reliable strength development, even at sub-zero temperatures, gives rapid return to service.
• Pre-packaged material only requires mixing with clean water. Can be bulked out with sand or aggregate.
• High bond strength exceeds tensile strength of concrete, thus ensuring monolithic performance of the repair.
• Sets in 10 minutes at 20°C yielding a durable, high strength mortar.
• Dense matrix resists 10 bar water pressure. Very high diffusion resistance to acid gases and chloride ions.
• Sulphate resistance to class DS-5/5m of BRE Special Digest 1 and ideally suited for sewage and wastewater applications.
• Portland cement base with physical properties of cured material similar to base concrete.
• Non-toxic when cured and is listed as authorised under Regulation 31 for use in the supply of drinking water.
• Economic mortar requiring no substrate or inter-layer priming. Part bags can be mixed.
• Suitable for use on correctly prepared concrete of at least 20 kN.
• CE marked in accordance with EN 1504-3. Suitable for repair methods 3.1, 7.1, 7.2 as defined by BS EN 1504-3.
• Compliant with Highways Agency Standard BD27/86 for the repair of Highway Structures.
• Compliant with LU Standard 1-085 ‘Fire Safety Performance of Materials’.
• Can be applied using a trowel or putty knife.
