When resurfacing a bath, always use the paint manufactured for the purpose. The job will take about five days, during which the bath must not be used.
Rub down the surface thoroughly – first with glasspaper and then with wet-and-dry paper. Clean the bath and wipe it dry. Fit tins or plastic beakers under the taps to catch any drips. Then brush on a thin layer of undercoat. When this has dried, brush on the first top coat – as thinly as possible – and leave it for a day. Work from the bottom up. Then apply a second top coat, this time leaving it for two days. Keep the bathroom well ventilated, as the fumes of the paint can be dangerous.
Finally, fill the bath up to the overflow with cold water and leave it for a further forty-eight hours.
