Asian Paints SmartCare Repair Mortar is a ready to use single component polymer modified repair mortar. It is specially designed for repairs of RCC members like beams, columns and slabs because of its good compressive strength and shrinkage resistance. It is pre-blended with special additives which provides it excellent workability and adhesion to host concrete/masonry surfaces.

Easy to use: Single component ready to use powder which only requires addition of water at site Shrinkage compensation: Dual shrinkage compensated and hence crack resistant Bonding: Excellent bond strength to concrete and other masonry substrates Strength: Develops high initial and ultimate compressive strength Thickness: Suitable for repair of thickness up to 50 mm (maximum thickness in a single coat: 25 mm)

Surface Preparation 

• Surface should be completely free of laitance, oil, dust, grease, plaster, paint, corrosion etc.
• Smooth surface should be mechanically roughened by scrabbling or needle gun to form a good key. Edges of the areas for repair must be saw cut to 12 mm to avoid feather edging
• The substrate should be thoroughly soaked with clean water and any excess should be removed.
• Apply bonding agent if required
• SmartCare Repair Mortar must be mixed with a slow speed drill (500 rpm) fitted with a spiral paddle
• Minimum thickness to be maintained 10 mm. 
• For higher thickness more than 25 mm, bond coat is recommended before applying second coat. 
•  Strictly maintain water powder ratio.
• Temperature of the mix should be maintained at approx. 30°C. During summer use cold water and in winters use warm water to regulate the temperature of the mix.
• Mechanical stirrer to be used for mixing, avoid hand mixing

• Renderoc SP40 is suitable for wet spraying and hand application in a wide variety of repair applications, and is particularly well suited to vertical and overhead repairs. Typical applications would include, but not be limited to, the following: 
• Mass infi ll to large areas 
• Repairs to irregular profi les 
• Excellent for repairs to fi re-damaged concrete 
• Fast track repair programmes, where rapid application at high volume is required 
• Single layer, high build applications

Advantages

• Cost eff ective - shrinkage control enables repairs to be completed „right fi rst time‟. Very low rebound is an additional cost benefi t 
• Enhanced durability - works in tandem with extremely low permeability to prolong eff ective working life
• Compatibility - aligns performance closer than ever before, to that of host concrete 
• User friendly - specifi cally developed to provide an easyto-apply product, suitable for local conditions 
• Defi nable performance - positive benefi ts are easily demonstrated via a single, simple measurement 

Renderoc SP40 is supplied as a single component, ready to use blend of dry powders and fi bres which requires only the addition of clean water to produce a highly consistent, hand and spray grade, repair mortar suitable for most structural and load bearing repairs
