MasterEmaco SBR 3

Styrene-butadiene (SBR) latex bonding agent and waterproofing gauging liquid for cement, mortar and plaster

Product Overview

MasterEmaco SBR 3 is a milky-white styrene-butadiene (SBR) co-polymer latex produced by high-pressure emulsion polymerization. Added to cement, concrete, mortar or plaster, it works as a bonding agent and gauging liquid that sharply improves adhesion between fresh and hardened substrates while raising waterproofing, flexural and abrasion performance. The polymer film reduces permeability, shrinkage and the risk of cracking, and improves resistance to chemical and carbonation attack. It is part of the Master Builders Solutions range (formerly BASF Construction Chemicals) and is available through Space Arc Engineering, an Authorized Project Distributor in India. Typical uses include bonding slurries for repairs, waterproof renders and screeds, and polymer-modified patch mortars. Always condition and prime the substrate as detailed in the technical data sheet for best results.

Features & Benefits

Improves bond strength between new and existing concrete, mortar and plaster
Enhances waterproofing and reduces permeability of cementitious mixes
Lowers drying shrinkage and the tendency to crack
Increases flexural, tensile and abrasion resistance of repair mortars
Improves chemical, carbonation and freeze-thaw durability
Easy to use as a bonding slurry, primer or gauging liquid with site cement

Technical Highlights

Coverage	Typical dosage around 200 ml SBR per kg of cement (about 5 litres per 25 kg cement bag); coverage of bonding slurry depends on substrate texture — refer to TDS.
Strength	Polymer modification markedly improves bond, flexural and tensile strength of the mortar; exact gain depends on mix design — refer to TDS.
Performance	Reduces water permeability and shrinkage cracking while improving abrasion and chemical resistance of cementitious systems.
Application Conditions	Apply to a sound, clean, pre-saturated (surface-dry) substrate; protect fresh work from rapid drying — refer to TDS for ambient limits.
Packaging	Supplied as a liquid in containers (e.g. 4.5 L, 10 L and 20 L); confirm current pack sizes with Space Arc Engineering.

Applications

Bonding slurry for concrete repairs on bridges, water tanks and industrial floors
Polymer-modified repair and patch mortars for spalled or damaged concrete
Waterproof renders and screeds for basements, terraces and wet areas
Bonding new screeds and toppings to existing concrete substrates
Durable plaster and mortar in residential and commercial construction

Frequently Asked Questions

What is MasterEmaco SBR 3 used for?

It is an SBR latex used as a bonding agent and gauging liquid in cement, mortar and plaster. It improves adhesion of new-to-old concrete, boosts waterproofing and durability, and reduces shrinkage cracking in repairs, renders and screeds.

How is MasterEmaco SBR 3 dosed and mixed?

A common rate is about 200 ml per kg of cement (roughly 5 litres per 25 kg bag). For a bonding slurry, SBR and water are blended and cement is added to a creamy consistency. Always follow the project-specific mix in the technical data sheet.

Does MasterEmaco SBR 3 make mortar waterproof?

Used as a gauging admixture it significantly reduces permeability and improves water resistance of mortars and renders, making it suitable for wet areas and tanking systems when applied as specified.

Is it the same as the old BASF SBR product?

Yes. MasterEmaco SBR 3 is the Master Builders Solutions name for the SBR latex bonding and waterproofing liquid formerly marketed under BASF Construction Chemicals.
