Not sure which sealant your project needs?

This tool asks you five quick questions about your project — where the joint is, what it's touching, what it's exposed to — and gives you a straight answer: which sealant to use, which products to buy, and why.

Quick reference: which sealant for which job?

A short version of what the tool above works out interactively — useful if you already know your application and just want the answer.

Bathroom, shower, and basin joints

Use a sanitary-grade anti-fungal silicone, never a general-purpose one. In Indian bathroom humidity, silicone without built-in fungicide typically shows mould within 6–12 months. If the surrounding surface is marble or natural stone, insist on a neutral-cure formulation — acetoxy-cure silicone releases acetic acid while curing, which permanently stains stone.

Glass façades and ACP cladding joints

Neutral-cure, medium-modulus silicone rated for at least ±50% joint movement. ACP panel surfaces can hit 70–80°C in direct sun and expand several millimetres across a single day, which is well beyond what PU sealant is built to handle over a 15–20 year building life.

Structural glazing

Two-component structural silicone only, engineered to ASTM C1184 / ETAG 002, with joint dimensions calculated by a structural engineer. This is a life-safety application — there is no substitute product and no site-estimated joint size.

Window and door frames

Depends on the frame material. Aluminium, uPVC, and glass frames need neutral-cure silicone. Wooden or masonry frames that will be painted need a one-component PU sealant instead, since cured silicone cannot be painted over.

Concrete and masonry expansion joints

One-component PU sealant is usually the right choice — it bonds directly to porous concrete and brick without a primer and can be painted once cured. For joints in constant direct sun, a UV-stabilised PU or a hybrid MS polymer lasts longer than standard PU.

Roof and parapet joints

Neutral-cure silicone or a hybrid MS polymer, not standard PU. Roof-level joints see the harshest UV and temperature swings of any joint in a building, and standard PU sealant in that position commonly fails within 2–3 monsoon cycles.
