Product Description
Liquid integral water reducing cum waterproofing admixture for all types of concrete and mortar
Conforms to IS 2645-1975

Uses
Sikacim® is recommended for use in structural and mass concrete, particularly for the following
• Casting of roof slabs
• DPC
• Beams
• Columns
• Water tanks
• Culverts
• Tunnels
• Sewerage works
• Virtually wherever watertight concrete is required
• Excellent for internal and external plaster of buildings etc.
• Repair and renovation

Characteristics / Advantages
• Compatible with all varieties of Portland Cement including Slag Cement
• Minimises loss of mortar due to rebound in plastering jobs, hence great ease of application and saving
• Required at a very small dosage, hence economical
• Improves water tightness to a great extent
• Performs multiple roles of water reducer as well as waterproofer
• Improves workability without increased water content
• Reduced shrinkage, better finish
• Acts to disrupt the leakage causing capillary structures formed in concrete to cause leakages
• No added chloride thus not contributing to corrosion of steel
• Convenient to handle since suitable for both concrete and mortar
• Supplied in consumer friendly pack

Sika Latex Sika Latex

Mortar and slurry modifier cum bonding aid
Product Description
Sika® Latex is a synthetic rubber emulsion which when added to cement mortar/concrete/grout provides good adhesion and water resistance. It comes in the form of a milky liquid. It is fully soluble in water and is to be added directly to the gauging water of mortar/concrete/ cementitious grout.

Uses
• Sika® Latex is a high quality emulsion that substantially increases the qualities of cement mortar/concrete/ cementitious grout. The scope of application are as follows:
• Rendering and Coatings
• Bonds rendering and coating layers
• Makes waterproof coating for tanks & pools for either fresh or sea water
• Ensures high wear resistance against erosion
Jointing
• Long life and watertight masonry joints
• Concrete Repair & Adhesive Mortar
• Repair of spalling even on prestressed or reinforced concrete
• Roof Finishing Adhesion and Hardener for Plaster Work
• Bonding for plaster works by bond-coat
• Bonding of Concrete Casts
• Bonding between successive concrete casts by incorporating Sika® Latex into bonding mortar
Tiling
• Used in bonding mortar for tiles & panellings
Waterproof Rendering & Cement Injection Mix
• Wet rendering of walls for weather proofing
• Injection into cracks or porous concrete works

Characteristics / Advantages
Sika® Latex improves the following properties:
• Adhesion to most substrates (concrete, stone, brick, ferrous metals, glass, ceramic tiles)
• Improves elasticity, flexibility and tensile strength
• Easy to use, non-toxic & plasticising mortar
• Inhibits cracking, improves surface hardening, limits wear and dust production
• Makes the mortar waterproof and reduces susceptability to acids and greases
• Mortar with Sika® Latex shows extremely good bonding to bases like concrete, stone, brick etc.
• Reduces viscosity of cement injection grout and improves bond of cured injected materials with substrates

Product Data
Appearance / Colour : White (milky) liquid
Packaging : 20 kg, 50 kg and 100 kg container

Storage
Storage Conditions / Shelf Life :
12 months from date of production if stored in undamaged and unopened, original sealed packaging, in dry conditions and protected from direct sunlight. Protect from frost.

Technical Data
Chemical Base : Styrene butadiene rubber emulsion.
Density : ~ 1.02 kg/l at 27ºC

System Information
Substrate Quality : Clean and dry, homogeneous, free from oils and grease, dust and loose or friable particles. Paint, cement laitance, old coatings and any other contaminants.

Substrate Preparation : Cementitious substrates should be pre-saturated surface dry with clean water.

Application Instructions
Mixing : Mixing of diluted Sika® Latex to cement mortar should preferably be done manually. When a concrete-mixer is used, pour the mortar as soon as its consistency is cohesive. Do not run the mixer too long.

Cleaning of Tools : Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.

Curing Details
Curing Treatment : It is important to avoid rapid evaporation of the Sika® Latex for Mortars. It is recommended to cover the surface with a polyethylene film, use water misting or apply Sika® Antisol® curing compound.
During adverse weather conditions (high temperatures, low relative humidity, wind, sun etc.) take particular care with curing precautions.
