How do I repair a chipped or cracked tile?
Short Answer
Small chips and hairline cracks can often be patched. Major chips and full cracks need tile replacement - which is why ordering 10% wastage spares is so important.
For SMALL CHIPS (under 5 mm):
1. Clean the chipped area with a damp cloth.
2. Fill with a colour-matched tile filler / epoxy putty (Quikfix, Pidilite tile repair).
3. Smooth flush with a flat blade.
4. Touch up with tile paint if colour mismatch is visible.
For HAIRLINE CRACKS:
1. Clean and dry the crack.
2. Fill with epoxy crack filler.
3. Wipe excess immediately.
For MAJOR CHIPS, BROKEN TILES OR LARGE CRACKS:
Step 1 - Remove the broken tile carefully without damaging neighbours.
Step 2 - Chip out the old adhesive from the substrate.
Step 3 - Apply new tile adhesive.
Step 4 - Lay the replacement tile (your wastage spare), set level with surrounding tiles.
Step 5 - Let adhesive cure 24 hours.
Step 6 - Grout the joints with matching grout colour.
Step 7 - Wipe clean.
Without a wastage spare, you'll need to find the same tile from the same batch - often discontinued or shade-mismatched.

Detailed Explanation
Chipped and cracked tiles are inevitable over a 20-year tile lifetime - dropped utensils, moved furniture, foundation settling, occasional impact damage. The good news is most damage is repairable, and proper installation (with grout joints and wastage tiles in storage) makes repair straightforward.
For SMALL CHIPS (under 5 mm) - the patch method:
1. Clean the chipped area thoroughly with a damp cloth, then dry it.
2. Apply a colour-matched tile filler or epoxy putty. Products: Pidilite Quikfix Tile Putty, Roff tile repair epoxy, ARDEX X repair epoxy.
3. Press the filler into the chip with a flat blade or putty knife.
4. Smooth flush with the surrounding tile surface.
5. Wipe off excess immediately before it sets.
6. Let cure 24 hours.
7. If colour mismatch is visible, lightly touch up with a tile-specific paint pen or a dab of acrylic paint matched to the tile.
For HAIRLINE CRACKS - the seal method:
1. Clean and dry the crack carefully.
2. Apply a thin bead of epoxy crack filler or super-thin epoxy adhesive into the crack.
3. Wipe excess off the surface immediately.
4. Let cure 24 hours.
5. Hairline cracks in a non-wet area are mostly cosmetic. In a wet area (bathroom floor), the crack must be sealed to prevent water seepage into the substrate.
For MAJOR CHIPS, BROKEN TILES, or LARGE CRACKS - the full replacement method:
Step 1 - Remove the broken tile carefully. Cover surrounding tiles with painter's tape and cardboard to protect them. Use a chisel and hammer (or a tile cutter blade) to break the damaged tile into pieces from the centre outward. Take care not to damage neighbouring tiles or chip them at the edges.
Step 2 - Chip out the old adhesive from the substrate. Get back to a clean, flat surface that matches the level of the surrounding tiles. Vacuum out dust.
Step 3 - Apply new tile adhesive (same Type 3 polymer-modified adhesive as the original installation). Use a notched trowel for even spread. Back-butter the replacement tile if it's large-format.
Step 4 - Lay the replacement tile (your wastage spare). Set it level with the surrounding tiles using a spirit level. Use tile spacers in the joints to match the existing grout width.
Step 5 - Let adhesive cure 24 hours undisturbed.
Step 6 - Remove spacers. Grout the joints around the new tile with grout matched to the existing colour (cement grout in dry areas, epoxy grout in wet). Apply with a grout float, wipe excess off the tile face immediately.
Step 7 - After 30 minutes, wipe the tile face with a damp sponge to remove grout haze. Light buff with a dry cloth after 2-4 hours.
Step 8 - Full use after 72 hours.
Why ordering 10% wastage matters here:
When a tile chips or cracks 2-3 years after installation, you'll need to replace it with an IDENTICAL tile - same SKU, same shade, same batch ideally. Tile batches are produced in runs and shade can vary slightly between batches. Designs are also regularly discontinued.
If you have wastage spares stored in their original boxes (clearly labelled with the SKU and batch number), repair is a simple swap. If you don't, you face:
1. Hunting for the same tile across multiple suppliers.
2. Settling for a shade-different replacement that doesn't match.
3. Worst case - re-tiling a whole area or room to maintain visual consistency.
Store your wastage spares in their original boxes in a dry place. Note the SKU code and the room they came from. A small investment of cupboard space saves you from a major re-tiling job later.
When to call a professional vs DIY:
1. DIY: small chip patching, single broken tile replacement in a non-wet area.
2. Call a professional: multiple broken tiles, broken tile in a wet area (requires waterproofing check), cracked tiles in heavily-trafficked areas, structural cracking that suggests substrate movement, broken slab tiles (heavy and hard to handle), broken parking floor tiles (need precise level for vehicles).
