MYK Arment ReArm SBR 45 is a modified Styrene butadiene Rubber emulsion specially designed for use as a mortar modifier for cementitious systems and a bonding aid. It is suitable as an admixture for obtaining waterproof concrete, plasters and mortars. It is also suitable for preparation of repair mortars damaged and spalled concrete.

Uses:

• Concrete repair and adhesive Mortar, screed
• Modifying and improving bonding of floor toppings
• Repair of Worn Damaged and spalled concrete
• Repair of large cracks
• Polymer modified Floor screeds
• Rendering smooth good finish water tight external plaster.
• Thin layer patching mortars
• Tile fixing mortars, Masonry Mortars

Features and Benefits:

• Simple use & thin application is possible
• Single component,
• Provide excellent bond to concrete, adhesion
• plaster, masonry, stone work, etc.
• Weather resistant helps improved durability
• Impermeability to chloride and other harmful agents
• Provides water tight screeds, plasters
• Improves tensile, adhesion and flexural properties
• Compatible with all hydraulic cements
• Economical to use.
• Improves cohesion and workability
• High resistance to freeze/thaw cycling

Application Methodology:

Step no 1: Surface Preparation

The base must be clean and free from loose particles. Unsound areas should be removed until sound concrete is located. Any cracks, pot holes etc. should be properly sealed and cured. The surface to be treated should be free from all coatings dust and unsound concrete toppings. The unsound parts should be chipped of to arrive at sound surface.Smooth substrates must be mechanically roughened/ abraded e.g. by scrabbling, needle gun or grit blasting to provide an adequate key. Corroded reinforcing steel
should be exposed around its full circumference and cleaned to remove all loose scale and corrosion deposits. It is always preferably to clean the steel to a bright condition. Use of emery cloth, grit or sand blasting, or ReArm Rust Remover / ReArm Rust Converter is recommended.

Step no 2: Substrate priming

The substrate should be thoroughly soaked with clean water and any excess removed prior to commencement. A slurry primer should be prepared consisting of 1 volume ReArm SBR 45 to 1 volume clean water to 3 volumes fresh cement. To obtain a smooth consistency, the cement should be blended slowly into the premixed liquids. The slurry primer should be stirred frequently during use to offset settlement.The slurry primer should be scrubbed well into the surface of the concrete. Avoid applying too thickly and avoid ‘puddling’. The repair mortar, topping or render must be applied on to the wet slurry primer. If the slurry primer dries before application of the mortar, it must be removed (ground off)and the area reprised before continuing.In exceptional circumstances, e.g. where a substrate/repair barrier is required or where the substrate is likely to remain permanently damp, FloArm Primer EP bonding aid should bused.

Step no 3: Application Information

Step no 4: Application Instructions

Mixing:

MYK Arment ReArm SBR 45 is to be added to cement/ cement mortar/concrete/grout depending on the type of application as per the table above. Mixing of diluted
ReArm SBR 45 to cement mortar should preferably be done manually by volume as per the table. Please note that when a Waterproofing Slurry or Bonding Coat is to be prepared Cement is to be added in the Polymer for getting consistent mixture.

Curing:

ReArm SBR 45 mortars, toppings and renders are cement based. In common with all cementitious materials, they must be cured immediately after finishing in accordance with good concrete practice. The use of one of MYK A Armix Cure WB curing compounds, sprayed on to the surface of the finished mortar in a continuous film, is recommended. In harsh drying conditions, supple mentary curing with polythene sheeting must be used.

Finishing:

ReArm SBR 45 mortars can be finished with a steel, plastic or wood float, or by a damp sponge technique, to achieve the desired surface texture. The completed surface should not be overworked.
