Sika Cool Coat Primer — acrylic primer for elastomeric waterproof roof coatings (4 kg)

Sika Cool Coat Primer is a premium, water-based acrylic bonding primer from Sika India Pvt. Ltd. — specifically engineered to prepare and strengthen concrete, masonry, and plastered roof surfaces before the application of elastomeric waterproof roof coatings and reflective cool coat systems. As a foundational waterproofing chemical in the Sika Cool Coat range, it penetrates deeply into porous substrates — consolidating loose particles, sealing micro-pores, and dramatically improving the adhesion of subsequent roof waterproofing topcoats for long-lasting performance.

Formulated with a chemically inert acrylic polymer base, Sika Cool Coat Primer creates a uniform, stable bonding layer across roof slabs, terraces, and parapet walls — ensuring that the overlying waterproof coating bonds seamlessly without delamination, blistering, or premature failure. Its alkali-resistant formulation provides a reliable barrier over newly plastered and highly alkaline concrete surfaces — preventing topcoat degradation and delivering a consistent waterproofing solution for roof applications across India's most demanding construction environments.

By significantly improving surface adhesion and reducing substrate porosity, it maximises the effectiveness of every roof waterproofing system applied over it — making it an essential waterproofing chemical for waterproofing contractors, civil applicators, and construction professionals who demand reliable, long-term roof leakage solution performance. A trusted primer from Sika India relied upon across India for superior terrace waterproofing and roof waterproofing system preparation on both new construction and renovation projects.
