Repairing a chip in a bath requires different materials and techniques depending on whether the bath is acrylic or enamel. Here is exactly how a professional repair is carried out on each.

Acrylic Bath Chip Repair — Step by Step

Step 1 — The chip is cleaned and any loose material removed. Edges are prepared to give a clean bond surface.
Step 2 — Colour matching. The specific white or colour of the acrylic is matched from the technician’s library. Acrylic baths age slightly to cream or off-white over time — this is matched, not the original factory white.
Step 3 — Acrylic repair compound is applied in layers into the void, allowing each layer to cure before the next.
Step 4 — The repair is sanded flush when fully cured, working through progressively finer grades.
Step 5 — The repair is polished to match the gloss level of the surrounding surface.

Enamel Bath Chip Repair — Step by Step

Step 1 — If the chip has exposed metal and rust has begun, the rust is treated first with a rust converter and stabiliser.
Step 2 — The chip is cleaned and edges prepared.
Step 3 — Specialist enamel repair compound is matched to the aged enamel colour.
Step 4 — The compound is applied in layers.
Step 5 — Sanded and polished to match the surrounding enamel finish.

The key difference from acrylic: enamel does not flex, so the repair material does not need to be flexible. Enamel repair compounds are harder and more durable than acrylic compounds.
