Any plumbing periodically fails or deteriorates, therefore, even on the bath, ugly cracks are formed and rust arises, and the enamel ceases to be smooth and brilliant. In this case, you can purchase a new one or restore the old enamel.
All cracks and spots of rust must be thoroughly cleaned with sandpaper. Thanks to this, you will get a flat and smooth surface. If the rust is not removed, then for it you can use oxalic acid, which needs to be mixed with water and using cotton wool treat the necessary places. However, so that the acid does not damage the enamel, it cannot be left more than half an hour. By the way, now the price of vertical blinds has fallen much, so many began to buy them.
Next, you need to thoroughly dry the enamel of the bath, for which a fan or hairdryer can be used. There are several ways to restore it. Typically, the bath is treated with a primer from the spray can, after the drying of which can be applied to the surface of the enamel, which must be applied to 3 layers. After drying, you can apply a solution that gives the bath to shine.
Small chips can easily be treated with special BF-2 glue, which must be applied in several layers. If the chips are too large, then you need to mix the nitroemal, which will be similar to the bathroom, with glue and apply the solution to chips several times, about a day in a day.
