Its non-sag, high-bond formula ensures a flawless finish on interior and exterior walls, ceilings, and foundations. Whether you’re repairing a living room hairline crack or performing a concrete foundation wall crack repair, Cracksil delivers lasting strength, waterproofing, and smooth results. Made in India, built for Indian weather, Cracksil keeps your walls strong, dry, and beautiful.
The Problem - Cracks in Walls, Plaster & Concrete
Cracks appear in every type of wall, cement plaster, concrete slabs, or brickwork. Over time, movement, moisture, and temperature changes widen them, leading to peeling paint, dampness, and structural wear. In India’s monsoon-prone and heat-fluctuating climate, this is inevitable.
Most putties or quick fixes fail because they don't deeply bond and don't withstand the forces of weather changes. Homeowners and contractors alike require a specific waterproof wall crack filler that seals and reinforces the crack and the structural substrate. Cracksil solves this problem with a flexible, durable formula designed specifically for home wall crack repair and plaster crack sealing.
What Is Cracksil? - The Smart Wall Crack Filler for Indian Homes
Cracksil is a polymer-modified, cement-based filler that penetrates deep into cracks and bonds firmly with concrete and plaster surfaces. Its hydrophobic technology forms a moisture barrier, acting as both a wall crack sealer and surface protector. Suitable for cracks up to 6 mm wide, Cracksil can be used on cement block walls, plaster joints, or foundation walls.
Unlike conventional fillers, it resists sagging and shrinkage, even on vertical or overhead surfaces. The result: a seamless, paint-ready surface that lasts.

मैंने हाल ही में अपने टैरेस के लिए 20MCC के वॉटरप्रूफिंग समाधान का इस्तेमाल किया था, और मैं अविश्वसनीय रूप से प्रभावित हुआ हूँ! टीम न केवल पेशेवर और कुशल थी, बल्कि उन्होंने जो उत्पाद इस्तेमाल किए वे वाटरप्रूफिंग में बहुत प्रभावी साबित हुए हैं, जिससे मेरे टैरेस में पहले आने वाली सीलन में नाटकीय रूप से कमी आई है। सभी वॉटरप्रूफिंग आवश्यकताओं के लिए मैं 20MCC की अत्यधिक अनुशंसा करता हूँ!
