Over time, any bath, including cast iron, loses its aesthetic appearance. On its surface, traces of rust and streaks are formed, and to the touch it becomes rough. From this situation, there are 2 ways out: to buy a new bath or to restore the old one. Due to the fact that buying a new product will cost a round sum, not everyone can afford it. Therefore, today the actual question is how to restore the old cast-iron bath.
After prolonged use, any tub loses its attractive appearance and needs to be restored.
One of the most effective ways of restoration of a cast iron product is its treatment with liquid acrylic. Therefore, further on, we will consider how to restore the bath with liquid acrylic.
Tools and materials
To restore the cast-iron bath with liquid acrylic you will need such tools and materials:
To restore the bath you will need liquid acrylic.
- a hammer;
- grinding wheels;
- rubber spatula;
- latex gloves;
- painting tape;
- rust converter;
- abrasive powder;
- liquid acrylic and hardener;
- lint free rags.
Restoration of the cast-iron bath is carried out with the help of liquid acrylic - stakryla. Stakril is a two-component acrylic mixture, which is acrylic in liquid form and a special hardener. When these components are joined together, the polymerization process begins, so that after a while the glass turns into a durable and reliable acrylic coating with a thickness of about 5 mm.
Among the main advantages of the stakryl are:
- Fluidity. Allows the substance to self-coat the surface of the product evenly.
- Viscosity. Specially chosen experimentally, the viscosity value allows creating an acrylic coating with a thickness of up to 4 mm on the sides of the bath and up to 6 mm on its bottom.
- Deferred polymerization. Due to this property it is possible to carry out restorative work without haste.
You can use grinding wheels to clean the surface of the old coating bath.
The procedure for the restoration of cast-iron baths begins with preparatory work. The first step is to remove the siphon. This will protect the sewer from clogging with debris. If a new siphon is installed on the bath, it is necessary to unscrew the 2 bolts on the drain and overflow grate for its removal. If an old cast-iron siphon is installed, the process of removing it becomes much more complicated. First, with the help of a grinder, cuts are made on the grilles and overflow grids, after which the overflow grill is knocked down with a hammer. Then it is necessary to break off the overflow pipe from the main part of the siphon, after which, with the help of a hammer and a screwdriver, the previously cut incision grid is peeled off.
After the siphon is removed, you can proceed to cleaning the surface of the bath. This stage is very important, since the quality of applying liquid acrylic will largely depend on the correctness of its performance. To remove the old coating, the surface of the bath must be treated with sandpaper or a grinding wheel, having previously filled the bath with abrasive powder. Areas where corrosion is present should be treated with a rust converter. After that, the exfoliated enamel and dust are washed off with water.
At the next stage, the surface of the cast iron product is degreased, after which the bath is again washed with warm water and wiped dry with a lint free rag. Before applying the stakryla, make sure that there is no debris or villi on the surface of the bath.
Application of acrylic
Acrylic paint should be applied to the side of the bathroom and wait for it to drain down.
Directly before applying liquid acrylic, the formulation is mixed according to the instructions on the packaging. After that, part of the prepared mixture is poured into a separate container (for example, a cut plastic bottle). First a small amount of stakryla is poured onto the bath wall, and with the help of a rubber spatula the mixture is pulled to the joints.
Then acrylic is poured on the side with a small jet so that it slowly drains to the middle of the wall. In this way, the jet moves along the entire perimeter of the cast iron bath to the starting point.
When applying liquid acrylic, rush is useless.
If in the course of the work, streaks are formed, then there is no need to worry, because during the polymerization process they will disappear.
At the last stage, the acrylic mixture is poured into the middle of the cast iron product. Surplus mixtures will drain through the drain hole, so under it you need to put some capacity.
After the glass has hardened (1-5 days), you can install a siphon and use the bathroom for its intended purpose. It should be noted that to repair a cast-iron bath of 1.5 m² it will take 3.4 kg of liquid acrylic and about 2 hours of free time without taking into account the time spent on preparatory work.
