Asian Paints SmartCare Crack Seal is a ready-to-use crack filling compound reinforced with fibre glass, for sealing cracks on both interior and exterior walls before painting.
Cracks are the single most common reason a paint job fails early. Paint over an unfilled crack and the crack simply reappears through the new film within a season — often wider, because water has been getting in behind it. Filling first is not an optional refinement; it is the difference between a repaint that lasts its warranty and one that doesn't.
What the fibre-glass reinforcement adds is resistance to the crack reopening. Ordinary filler is rigid: as the wall moves with heat and moisture, the filler cracks along the same line. Fibre reinforcement gives the filled joint something to hold it together through that movement. And because it is ready to use, there is no mixing, no ratios, and no pot life to work against — you open it and apply it, which makes it practical for a homeowner and fast for a contractor.
Two pack sizes: 360 g for spot repairs, 900 g for a wall or a full room's worth of cracks.

How to Fill a Crack Properly
Step-by-Step
- Open out the crack slightly with a scraper or blade so the filler has something to key into — filling a hairline surface crack without opening it rarely holds
- Remove all loose material, dust, and flaking paint from inside and around the crack
- Make sure the surface is clean and dry before applying
- Press the compound firmly into the crack so it fills the full depth, not just the surface
- Level it flush with the surrounding wall and allow it to cure fully
- Sand smooth if needed, then prime and paint over the repair
If a crack keeps returning after filling, or runs diagonally across a structural element, stop and have it assessed — a persistent structural crack needs a different remedy, not more filler.

1) Can I just paint over a crack instead of filling it?
No — the crack will reappear through the new paint, usually within a season and often wider, because water gets in behind it. Filling first is what makes the difference between a repaint that lasts and one that doesn't.
2) Does it need mixing?
No. It's ready to use straight from the pack — no mixing, no ratios, and no pot life to work against. That makes it practical for DIY as well as fast for contractors.
3) What does the fibre glass reinforcement do?
It resists the crack reopening. Rigid filler cracks again along the same line as the wall moves with heat and moisture; fibre reinforcement holds the filled joint together through that movement.
4) Can I use it outside as well as inside?
Yes — it's formulated for both interior and exterior surfaces, so one pack covers both jobs.
5) Which pack size should I buy?
360 g suits spot repairs and a handful of cracks. 900 g is better for a full wall or a room with cracking throughout. Since it's ready-mixed, buy the size closest to your actual need rather than over-ordering.
