Bought this before monsoon hit Mumbai this year. My terrace had 3 cracks that were leaking into my bedroom for 2 seasons. Applied this in one evening and the next day it rained heavily — not a single drop inside. Highly recommend to anyone with roof leakage issues.

Bohot achha product hai. Hamare bathroom ki tiles ke beech mein se paani aata tha. Is sealant se band kar diya. Easy application aur result bhi accha hai. Puri family khush hai.

Great product. I used it on my overhead water tank joints that were leaking. Applied it around all the edges and it set within a day. No more water dripping on the terrace floor. Fast delivery too.

Kerala monsoon is very heavy and our old house had multiple seepage points. Used this on window frames and external wall cracks. Works very well. Only thing is it needs 2 days to fully dry so plan accordingly before the rains hit.

Ordered 1 pack and sealed all the crack lines on my rooftop. The sealant is thick and easy to spread. My roof was a nightmare during July rains last year. This season — zero leakage. Worth every rupee.

Finally found a DIY solution to my leaking kitchen window. The plumber wanted ₹2500 just to come and check. I used this sealant for ₹899 and it solved the problem in 30 minutes. Smooth consistency, easy to apply with fingers. Excellent product!

Good quality for this price. Applied on roof parapet wall joints. Cured well and held through 2 heavy rain spells. One pack was enough for my small terrace. Highly useful product.

Our apartment balcony had water seeping in along the floor joint. The maintenance person quoted 3 weeks wait time. I just ordered this online, watched a 2 minute video, applied it myself on Saturday. By Monday it was perfect. No mess, no smell, great product.

Used it on my AC outdoor unit piping joints and wall entry point. It sealed everything perfectly. Packaging was good, arrived before estimated date. Will order again next season as a precaution.
Ananya Bhattacharya 📍 Kolkata, WB

Kolkata rain is intense and our old house walls used to literally sweat water during July–August. Applied this along all crack lines and window perimeters before monsoon. Massive difference this year. My walls are completely dry! Highly recommend before the rains hit.
❓ Frequently Asked Questions
Can I apply this sealant directly on a wet/damp roof?
For best results, the surface should be clean and dry before application. If it has rained recently, wait for the surface to dry completely — at least a few hours of sunshine. Applying on a damp surface may reduce bonding strength and curing time.
How long will it last after application?
When applied correctly on a clean, dry surface, the sealant can last multiple monsoon seasons. Its flexible formula prevents cracking due to thermal expansion and contraction. Avoid applying on surfaces with running water or in rain.
Is it safe to use around water tanks and drinking water pipes?
This sealant is primarily designed for external surfaces — roofs, walls, pipe joints, and structural gaps. For drinking water tanks or pipes that carry potable water, we recommend consulting a plumber and using food-grade approved sealants for internal contact areas.
How much area can one 750g pack cover?
Coverage depends on the gap width and depth. For narrow cracks (2–5mm), one 750g pack can cover approximately 8–12 linear metres. For larger gaps or porous surfaces like rough cement, coverage will be less. Order multiple units if you have a large area to seal.
Does it work on metal roofing sheets (tin/GI sheets)?
Yes, this sealant bonds well to metal surfaces including GI (galvanised iron) sheets, tin roofs, and metal pipe joints. Ensure the metal surface is clean of rust and dust before application. Light sanding of rusted areas will improve adhesion.
Can I paint over the sealant after it dries?
Yes, once the sealant has fully cured (24–48 hours), you can apply exterior paint or waterproofing coating over it. This is especially useful for matching wall or terrace colour after repair.
What is the colour of the sealant after drying?
The sealant typically dries to a neutral/grey or white finish depending on the batch. The exact colour may vary slightly due to manufacturing batches, but this does not affect its waterproofing performance in any way.
What is your return/refund policy?
We offer a 5-day return policy from the date of delivery. Items must be unused and in original packaging. Returns are not accepted for opened/used products, or based on colour or packaging variation. For defective products, contact us within 48 hours of delivery with photos for full resolution.
How fast will I receive my order?
We typically dispatch orders within 24–48 hours. Delivery to most Indian metro cities takes 3–5 business days. Prepaid orders receive an additional 10% discount. Track your order using the link sent to your registered email or phone number.
Can I use this for bathroom tile joints and shower areas?
Yes, this sealant works well for bathroom tile joints, shower corners, and washroom wall gaps. These are common leak points in Indian homes that worsen with repeated water exposure. Apply along the joint line, smooth with a wet finger, and allow to cure before using the bathroom.
