Newton HydroCoat 203-RM - Rapid Set & High Strength Repair Mortar 25kg

Newton Repair Mortar

Newton HydroCoat 203-RM is a rapid-setting structural repair mortar. It is designed primarily for the durable repair of concrete. Utilising the latest technology, this Portland cement-based, fibre-reinforced product is extremely strong and hardwearing. This makes it ideal for roads, runways, bridges, decks, floors and footpaths.

Requiring only the addition of water, this single-component mortar cures rapidly. Newton HydroCoat 203 quick set mortar is physically and chemically compatible with the host concrete. This means it is quick to exhibit a high adhesive and compressive strength.

Uses of Newton HydroCoat 203-RM

Newton HydroCoat 203-RM is used on floors that are subjected to heavy wear such as:

• roads
• runways
• bridges
• decks
• floors
• footpaths

It can also be used as a smoothing fillet for use with Newton Liquid Waterproofing Membranes.

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

One bag of Newton HydroCoat 203-RM produces 13.3 litres of usable product and up to 23 litres when bulked out with aggregate. When used to create a smoothing fillet, one bag of Newton HydroCoat 203-RM will produce 42.5 linear metres of a fillet that is 25mm x 25mm.

Applying Newton Rapid Set Repair Mortar

Newton HydroCoat 203-RM should only be installed by those experienced in structural waterproofing. Please follow the manufacturer’s instructions for full details across the range of applications.

Preparation:

• Mechanically remove all damaged concrete back to a sound core.
• Expose steel reinforcement to at least 25mm behind the bars and 50mm beyond the point at which corrosion is visible.
• Step the perimeter of the repair area to a depth of 10mm using a saw, disc cutter or preferably a power chisel.
• Ensure all areas are free from dust, oil, grease, corrosion by-products and organic growth.
• Roughen any smooth surfaces and remove surface laitance.
• Thoroughly soak the prepared surface with clean water until uniformly saturated, ensuring no standing water remains.

Mixing:

• Mechanically mix Newton HydroCoat 203-RM using a forced-action pan mixer, or in a clean drum using a drill and paddle.
• For normal applications, use 3.5 litres of clean water per 25kg bag.
• For part bags, use a 5.5:1 powder-to-water ratio.
• Notes:
  • In cold temperatures, tepid water may be used to adjust working life.
  • The product must not be mixed using a standard concrete mixer.
  • Pot life is approximately 10 minutes, depending on temperature and humidity.
  • For screeding applications or deep repairs, consult the relevant technical data sheets.

Application:

• Compact the mortar using a placing technique to remove entrapped air.
• Apply in layers not exceeding 50mm in vertical or soffit applications, or 100mm deep in pockets.
• When bulking out to a maximum depth of 300mm, support with shuttering and compact thoroughly.
• Do not polish with a steel float; instead, use a stiff brush on the wet surface to provide a slip-resistant finish.
