Multipurpose Admixture and Bonding Agent

FAP SBR LATEX is styrene butadiene latex supplied as a ready to use bonding agent in liquid consistency. It is used for repair of spalled concrete-floor, columns, beams, slabs &waterproofing of toilet and bathrooms, small terraces etc. As it bonds strongly to old and new concrete and plasters. It shrinkage, prevents cracking, dust pick up & improves abrasion.

Typical Applications & Advantages

• Improved strength & flexibility.
• Higher bond strengths.
• Reduced shrinkage cracking.
• Increased abrasion resistance.
• Lower w/c ratio & increased durability.
• Good general chemical resistance.
• Non-toxic, use with potable water.

Area of Application

• For concrete repairs - Spalled concrete of floors, columns, beams, slabs, parapets, etc.
• For waterproofing – Small roof terraces, sunken portions of toilets & bathrooms, & lift pits, balconies     & staircases.
• For waterproofing – liquid & effluent tanks, car decks & walkways.
• As a bonding agent – Bonding mortar for tiles & panels, as undercoat for special finishes such as top      rendering coat for chemical resistance floor.
• As a bond coat – for bonding of new concrete to old concrete, masonry stone work, plastering.
• For cladding – fixing or re-fixing of slip bricks, tiles, stones & marble bedding.

Instructions for Use

Surface Preparation : Use a wire brush to ensure all surfaces are clean, sound, and free from loose particles, old mortar, and laitance, dirt etc. Use a suitable chemical degreaser to remove any traces of oil and grease and wash down thoroughly with clean water. When laying slabs or screeds to existing concrete, surfaces must be rough. Lightly scale smooth surfaces prior to application of the fresh mix. When repairing damaged concrete, ensure that existing concrete is cut back to sound material.

Mixing : Mixing should always be carried out using a forced action pan type mixer such as a Crete angle. Does not hand mix unless a very small quantity is required. Add the cement and sand to the mixer and premix for approx. 1 minute. Initially add one-third quantity of the water required. Then add FAP SBR LATEX and mix for a further 2 minutes; add further quantity of water slowly until the desired consistency is reached. Keep water content to a minimum to obtain maximum hardened properties.

Dosage

• As waterproofing coating: Mix proportion by volume 1:1.5(SBR LATEX: CEMENT)
• As mortar modifier: 15-20% FAP SBR LATEX by weight of cement.
• As bonding agent: Mix proportion by volume 1:1(SBR LATEX: CEMENT)

Coverage

• As waterproofing coating 20-22 sq.ft/kg
• As bonding agent: 40-45 sq.ft/per coat

Health & Safety

As with all chemical products, caution should always be exercised. Protective clothing, Such as gloves and goggle, should be worn. Should any of the products be accidentally swallowed, do not induce vomit but call for medical assistance immediately. Ensure the container is available for the medical attendant to examine any relevant instructions and contents details.
