SIKALASTIC 450I — Liquid Polyurethane Waterproof Coating | Sika India (20 kg)

SIKALASTIC 450I is a liquid-applied polyurethane waterproof coating from Sika India Pvt. Ltd. — engineered to deliver seamless, flexible waterproofing protection across roofs, terraces, and exposed structural surfaces that face constant weather stress.

Unlike rigid coatings that crack over time, SIKALASTIC 450I forms a continuous elastomeric membrane directly on the surface — flexing with structural movement, bridging hairline cracks, and staying intact through thermal expansion, heavy rainfall, and monsoon cycles. It's exactly what roof waterproofing and terrace waterproofing applications demand from a long-term waterproofing solution.

As a liquid waterproofing system, it applies cleanly and consistently — no joints, no overlaps, no weak points. The seamless finish it creates is what makes it a preferred choice for waterproof roof coating on residential terraces, commercial rooftops, and industrial structures across India.

Backed by Sika — a globally trusted name in waterproofing chemicals — SIKALASTIC 450I is the dependable roof waterproofing chemical for waterproofing contractors and applicators who want performance that lasts, not just protection that looks good on day one.
