Sika Latex Super — SBR Polymer Bonding Agent & Waterproofing Admixture (20 kg)

The two failures that show up most often on a site aren't dramatic structural problems — they're the everyday ones. New plaster that doesn't bond properly to the substrate and starts peeling within months. Screeds that develop hairline cracks because the cementitious layer couldn't accommodate movement. Concrete repairs that lift away from the parent surface because the interface was never strong enough to begin with. These are the situations where a polymer modification of the cement mix isn't optional — it's what separates work that lasts from work that has to be redone. Sika Latex Super from Sika India Pvt. Ltd. is the SBR-based polymer that contractors reach for in exactly those situations.

Sika Latex Super is a styrene-butadiene rubber (SBR) polymer emulsion that gets added to cement-based mixes during gauging. It does two things that ordinary cement and water alone cannot do. First, it dramatically improves bond strength at the interface between the new cementitious layer and whatever it's being applied to — old concrete, masonry, existing plaster, steel reinforcement. Second, it modifies the cured matrix to be more flexible and far less permeable to water, which is why the same product serves both as a bonding slurry coat and as a waterproofing admixture in cementitious waterproofing systems.

The applications it's trusted for span the everyday and the specialised. Bonding slurries for plaster on smooth concrete surfaces where mechanical key is poor. Polymer-modified mortars for concrete repair work where the patch has to behave as one with the parent concrete. SBR-modified screeds where some flexibility and crack resistance is needed. Cementitious waterproofing systems for terraces, bathrooms, water tanks and basements where the polymer reduces permeability of the coating. Contractors and applicators use it because the chemistry works reliably across all of these without needing different products for each — and because Sika has built the kind of track record on Indian sites that means specifications written around Sika Latex Super tend to actually get followed.

A construction chemical from Sika India Pvt. Ltd. that solves bonding and waterproofing at the same chemistry level — Sika Latex Super is the SBR polymer specification for plaster bonding, repair mortars, screeds and cementitious waterproofing where the cement mix needs to do more than cement alone can deliver.
