Waterproof Crack Filler — Seals Wall & Terrace Cracks (Pack of 2)

Every monsoon, the same crack in the terrace opens a little wider and the same corner of the bedroom ceiling turns brown. Painting over it hides the stain for a month. It doesn't stop the water.

This filler goes into the crack, expands to fill it, and cures into a waterproof plug that moves with the wall instead of popping out.

What it does

• Fills and seals in one step — no separate primer or topcoat needed
• Waterproof cure — designed for cracks that see standing water, not just damp
• Stays flexible — walls expand in heat and contract at night; rigid filler cracks, this doesn't
• Paintable — takes emulsion or distemper once dry
• Two packs included — enough for a full terrace inspection round

Where people use it

• Terrace and roof hairline cracks before the rains
• External wall cracks where water tracks inside
• Around pipe entry points and AC drain holes
• Window sills and chajja edges
• Bathroom floor and skirting joints

How to apply

1. Widen the crack slightly with a screwdriver so filler can key into it
2. Brush out all loose dust and let the surface dry completely
3. Press filler firmly into the crack — overfill slightly
4. Level with a putty knife and leave 24 hours before painting

Common questions

Will this fix a crack that's already leaking? Stop the water first and let the area dry. Filler applied to a wet crack will not bond.

How wide a crack can it handle? Hairline up to roughly 5 mm. Anything wider needs a mortar repair first.

Is it safe on an exposed terrace? Yes — UV and heat stable once cured.
