Bath renovation – how to restore an old cast-iron or acrylic bath?

Is your bath covered in scratches? It no longer looks its best and you want to change that? A bathroom renovation can be expensive, so if you’re looking for a more cost-effective alternative, opt for refurbishing the bath. This process will let you restore the look and functionality of older models, whether cast iron or acrylic. How exactly should you do it? Find out below!

Why refurbish an old bath?

If your bathroom has stopped impressing you with its looks, you can refresh it at low cost, for example by focusing on the bath’s surface. Repairing it is not only a way to save money, but also to minimise waste. An old bath that’s losing its charm due to scratches or discolouration can be brought back to life with ease. The cost of refurbishing a bath is considerably lower than buying a new one, and the result will be just as satisfying.

What should the bath refurbishment process look like?

How do you refurbish a bath? Before you start, be sure to carefully check its condition. Look for visible damage such as chips, scratches or defects that may require repair. For cast-iron baths, it’s also worth assessing whether there are any signs of rust that could affect the durability of the new coating. Acrylic baths are often more prone to damage, so their surface should be inspected regularly.

Also pay attention to any dirt or residues that could affect the quality of the refurbishment. Be sure to remove them by choosing effective methods for cleaning bathroom fittings: see here. Proper preparation and checking the bath’s condition before starting work will ensure better durability and satisfying results.

Removing damage from the bath surface

Removing damage from the bath surface is the most important step in the repair process. For cast-iron baths, damage can be corrected by sanding and using specialised repair materials. It’s worth starting with sandpaper to smooth out scratches and chips, and then applying appropriate hardeners.

For acrylic baths, the process is similar, but you should exercise caution so as not to damage the acrylic itself. Any chips and other defects can be filled with specialist products intended for repairing this type of sanitaryware. Remember that eliminating cracks and scratches before painting the bath will not only improve the aesthetics, but also prolong the life of the new coating.

Choosing the right materials for painting

If you want an attractive result, you need to choose the right materials. Pay attention to the type of paint or enamel that will be used for the refurbishment. For cast-iron baths, it’s recommended to use enamel with high resistance to water and chemicals. For acrylic baths, spray paints can be the best solution, as they allow the coating to be applied evenly.

Before applying the paint, use a primer to improve adhesion and increase the durability of the new layer. And be sure to account for the drying time of each coat and any required curing to achieve the best result without risking damage to the painted surface.

How to paint a bath step by step?

Break the process of painting the bath into several steps. Once the surface is prepared and any damage has been repaired, apply a primer. When that dries, it’s time to start painting the bath. Spray enamel will be the easiest to use, but you can also opt for a brush and a special bath paint. Apply thin coats and allow each one to dry thoroughly before applying the next. And when you’re finished, neatly seal the joints between the bath and the walls with silicone sealant to ensure it’s watertight.

How to care for a refurbished bath?

If you want to enjoy great-looking sanitaryware for longer, look after it properly. Avoid using harsh cleaning agents that could damage the new coating. Instead, reach for gentle detergents and soft cloths that will remove dirt effectively without scratching the surface. Keep it regular. Also keep an eye on the condition of the silicone sealant around the bath, as damage to it can lead to leaks and further problems.

Summary

Refurbishing a bath is an excellent way to refresh an old model, whether cast iron or acrylic, while saving money and reducing waste. A well-executed refurbishment will extend the life of the sanitaryware and also increase the value of the entire bathroom. Good luck!
