Yellowed, rough, damaged, your bathtub is not as beautiful as it was in its youth, even if it still remains solid and of good quality? Before considering replacing it, be aware that in the event of minor damage it is quite possible to strip it and repaint it to restore it to its former appearance. However, since the renovation of a bathtub is still a rather technical operation, you must be well prepared for it, even entrust this task to a professional, if you are not a seasoned handyman.
Before the works
In any case, before embarking on bathtub renovation work, it is necessary to check the feasibility of your project: check the condition of your installation, make sure that rust has not weakened its structure and that the enamel is not too damaged. If there are minimal chips, as well as small scratches, a cold enamel application may be a good solution. For greater degradation, several coats of epoxy resin should be applied. If the bathtub is really damaged, we can consider installing an acrylic insert … if a change of spa bathtub is not ultimately more adequate.
For tenants, it is first necessary to obtain a written agreement from the lessor. Otherwise, even in co-ownership, no authorization is required for this type of work. On the other hand, you must always plan to remove the rubble from the site in accordance with the selective sorting rules of your municipality.
Have equipment to carry out its work
Once you have assessed the level of degradation of your bathtub to determine your concrete needs and choose the appropriate products, you need to secure your workspace. Make sure the room is well ventilated, as the products you are going to use can give off harmful gases. Empty the bathroom and put the tarps on the walls, the floor and the remaining objects (sink, mirrors, etc.) to protect them from paint splashes. Use protective goggles, rubber gloves and work clothing.
Prepare the renovation of your bathtub
Every renovation begins with the critical support preparation step. Often neglected, it is nevertheless necessary to obtain a uniform and lasting result. You have to start by removing the gaskets (if you decide to repaint a bathtub, you might as well change the gaskets at the same time!). Then you have to degrease and descale your bathtub, or even sand it with sandpaper, because the paint will not stick to a surface that is too smooth. Then you can fill in the enamel chips with two-component epoxy paste, which will need to be sanded again to make up any unevenness.
If your tub is very dirty and scaled up, you can use acid to strip it. Be careful though, because products of this kind can be extremely aggressive! It is better to reserve them for complicated cases to be entrusted to professionals. Acid-based paint strippers, for example, are often used by enamellers to clean drop-in bathtubs that have already been re-meshed, but the coating is starting to come off. For old cast iron or enameled steel bathtubs, the sandblasting technique can also be very effective: it allows the metal to be exposed and then redo a brand new and impeccable enamel.
Renovate your bathtub
Today it is possible to find a wide variety of products for the renovation of sanitary facilities on the market. Some enamel renovators are available as a kit, containing a two-component colored resin and sometimes even ancillary products such as a pair of gloves, a roller, an abrasive …
Most modern renovators do not require an underlay, but its installation is still recommended because it facilitates the adhesion of the enamel and ensures a good remeshing of the tub. Apply the primer with a lacquer roller and let dry for at least 12 hours.
For the installation of decorative resin paint, strictly follow the manufacturer’s instructions. In order to obtain an aesthetic result, several coats will be necessary. Apply your paint with a roller or brush, taking care to cross the passes, or use a low-pressure spray gun. The latter guarantees top results, but requires a certain know-how and good protection of the work area.
After a drying time (from 24 to 72 hours depending on the product), you can redo the silicone seals and take your first bath in a brand new bathtub!
