How to paint a cast iron bath: common tools and technologies
After a certain time, any plumbing equipment, even expensive and durable as a cast-iron bath, can become unusable. But a complete replacement is not the only way to eliminate unpleasant defects.
A compromise solution is cosmetic restoration of the surface of the product. Modern painting of the cast-iron bath is a very effective event, which can be even held independently.
Reasons for preference restoration
During regular use of the bathroom, its upper enamel layer becomes significantly thinner, as a result of which chips, scratches, blackness, and rusty stains appear.
The adoption of water procedures in such a bath is not very pleasant and aesthetic.
An old bath can ruin even the most expensive interior. Moreover, dirt and harmful microorganisms accumulate in microcracks and enamel damage, which is unsafe for health. Of course, this encourages the owners to think about changing the old bath to a new one.
But in this case a financial question arises, since modern baths, even the most inexpensive and not very high-quality ones, are expensive. In addition, when replacing a bath, it will be necessary to dismantle the old plumbing, which is almost always associated with a violation of the finishing elements. Therefore, not all homeowners for various reasons have the ability and desire to change the old bath to a new one.
These reasons include:
- lack of financial opportunity to buy an expensive bath
- unwillingness to spend time and money on transportation, dismantling, installing a bath and repairing tiles;
- the irrationality of changing the cast iron bath of the “Soviet” quality, since today such products are very expensive;
- saving, why throw out a cast-iron reliable bath that holds water for a long time.
However, artisanal owners often attend doubts about the positive results of the restoration. Often scares possible unpleasant odor, noise, dust, dismantling bath.
In this case, the best way out would be painting the bath. Indeed, the change of enamel is a fairly uncomplicated measure, but it requires accuracy and clarity in the execution of instructions. If you have the time and desire to save the family budget, then you need to prepare all the necessary tools and materials and start painting. Your bathtub will become fresh and perfect, as if from a store.
For the average consumer, the question immediately arises - is this undertaking justified from a financial point of view? Restoration of the bath in any case will cost much cheaper than buying a new one, regardless of the chosen method of work. You can not only save, but also increase the operational life of your bath several times.
Restoring the original appearance of outdated plumbing does not take much time and effort, and the results will surely please you. The cost of necessary materials in comparison with the price of a new high-quality bath is relatively low.
The main motivation for the preference for the restoration of cast-iron baths is the clear benefit of this event, the speed and ease of execution, the ability to give the product any desired shade. Today, several simple methods have been developed for returning a worn plumbing of the previous, flourishing type and continuing successful operation, and with a minimum of financial costs.
For this there are such methods:
- Drawing on a working surface of an old bath of the new enameled covering.
- Pouring the bowl of the bathroom with liquid acrylic.
- Installation on a damaged bath of a special finished acrylic liner.
The common opinion that only an experienced specialist can perform such work is mistaken. Carrying out these restoration works is quite accessible to everyone.Before you decide on independent actions or to entrust the matter to a professional, evaluate your capabilities. Painting the bath on its own will cost only the purchase of materials without payment of work.
Necessary stages of restoration
The need for restoration measures is determined if there are such defects on the bath surface as roughness, cracks, rust, loss of the original color. A complete renovation of the bath reservoir consists of five steps.
List of main works
Any painting of the cast-iron bath consists of such procedures as:
- Degreasing.Before restoration in any way, first of all it is necessary to thoroughly degrease the bath. To do this, remove lime and fatty deposits with the help of potent alkaline solutions and mechanical processing.
- Removal of old enamel.The process is carried out using sandpaper or grinding technology.
- Cleaning from dust and enamel residue.Obluschennaya enamel vacuum and rinse with water.
- Drying the surface of the bath.For high-quality drying of a bowl of a bath use the usual or construction hair dryer.
- Coloring process.It is performed according to the selected method.
The whole process of painting the bowl of the bath is to paint from the sides to the bottom of the entire surface. For greater efficiency, the application of the material is carried out in two stages. The bottom of the bowl is processed at the very end of the process. After restoration, it is necessary to dry the entire new bath surface. Depending on the material used, it is better to use the bathroom in 2-6 days so that the new coating is completely dry.
During work and during drying, it is necessary to prevent water, dust and any contaminants from entering the surface of the bath. To do this, the faucets and the shower are carefully insulated, and the door is tightly closed. Work is carried out in special clothes and gloves.
Types of degreasing and rules for their implementation
For obtaining a durable and reliable new coating, high-quality degreasing of the bath bowl before painting is of great importance. Degreasing can be done in two ways.In the first case, baking soda, a metal dish scraper and abrasive abrasive paper are used.
Baking soda is applied to the scraper and the entire bowl of the bath is processed in a circular motion, removing the fatty deposit. The most carefully handled the place of chips and cracks. Also washed borders on the sides of the tile tile. Masking tape is stuck on it before painting.
The same procedure is repeated using emery paper. If the pollution is not strong, the degreasing is carried out only with soda without using abrasive. This method is considered the most economical and is used in the restoration of all types of baths.
The whole degreasing process takes about 30 minutes. Grinding wheels and grinders are not recommended, as undesirable black marks can form on the surface. At the end of the bowl of the bath thoroughly cleaned from soda.This technology is most suitable for the restoration of baths with previously applied acrylic coating.
The second method of degreasing is more used in the treatment of enameled cast-iron baths. Here are used: a brush with a nap, sandpaper, a means for degreasing, automotive putty. After thorough strippingsandpaper, the entire area of the bowl of the bath for 5 minutes is applied with a brush degreasing agent.
The largest defects must be sealed with quick-drying putty. Carefully degreased drain and overflow. From the surface it is necessary to remove all applied materials to the factory base.
To check the quality of the degreasing on the surface of the bath water is poured. If water drops quickly flow off, not lingering or accumulating, then the procedure is carried out correctly.
It is very important that the right choice of technology works, the most suitable state of your bath, otherwise the restoration will not give the desired result.
Enamel bath restoration
Baths, the installation of which was carried out in the old time, differ enviable quality. But, as time has shown, their weak point is the enamel coating. Over time, during long-term operation, the enamel layer is depleted, red rust spots, a network of small cracks appear on the surface of the bath, whiteness and perfect coating are lost.
In this case, the economical owners will be able to correct the situation by restoring the bath with the help of uniform application of special enamel. Even the oldest bath will take on its original appearance after the organization of a high-quality new coating.
Features of the enameling
Say at once that this method of restoration is like not every bath. Paint enamel is the best solution if its surface:
- darkened, yellowed or dark spots are visible;
- became rough and covered with a network of small cracks;
- face lime deposits, mold;
- partially or completely missing enamel shine.
Such defects will easily disappear under the new enamel layer. But if the presence of more significant damage to the surface layer, such as volumetric chips, deep cracks or enamel falls off in pieces, then you need to use other restoration technologies, since this will not give the desired effect.
A positive result of the update also largely depends on the correct choice of the method of applying enamel and on the purchase of a quality product for work.
Saving on paint may lead to the need for re-restoration. Professionals recommend selecting products of well-known, proven manufacturers, despite the somewhat higher cost, because it fully meets all quality standards. Only a quality product will help you to restore the surface enamel layer of the bath to a snow-white state.
Excellent characteristics has enamel onepoxyor two-component polyurethane enamel. Painting itself must be done in two or even three layers to obtain a guaranteed result of restoration.
For the application of each new enamel layer a portion of the coloring composition is prepared anew. The components of the prepared enamel, after thorough mixing, begin to harden gradually and after 2-3 hours the mixture will be unsuitable for work. Therefore, the enamel is preparedin portionsin the right amount.
Before applying a new layer, the previous one is thoroughly dried and degreased according to the manufacturer's instructions. For better adhesion and fluidity of the composition, the enamel is kept in a container with heated water before mixing with the hardener.
Ways of painting the enamel bath
The most important and crucial step in the restoration of the bath is the application of enamel on the prepared surface. Without using the services of hired specialists, you can paint the bath at home with your own hands using two methods - painting with a flutter brush or spray gun with a compressor.
To perform restoration work using this method, you need the following:
- high-quality enamel;
- quick-drying primer for putty for larger cracks;
- acetone-type degreasing agent;
- roughsandpaperor other abrasive;
- napkins or rags of natural composition;
- construction tape, plastic film;
- rubber gloves and workwear.
Before work, the prepared coloring agent is better divided into two parts - for the starting and finishing coatings. The base layer of enamel is applied with a thin brush with a wide brush. Work begins with the edges of the tank bath to the bottom. It is necessary to cover the entire surface of the old layer with new enamel, smearing the paint with a brush carefully and evenly.
If the pile of the brush on the enamel is removed with a knife or tweezers, in no case touching the paint with your hands. Without waiting for the base coat to dry and preventingdustingalready applied enamel after 20 minutes doing finishing work.
The second part of the enamel is applied with the same brush with the direction of movement from the middle to the top. After painting, it is necessary to give time about 15-20 minutes for the spontaneous smoothing of enamel. Then, with a brush, the enamel smudges that have not been smoothed out from the middle to the edges are carefully removed.
This must be done while the enamel is still mobile and has not lost its fluidity. Now leave the bath alone until the enamel layer is fully expanded and dried.Plumbing can not be used for another 3-6 days, depending on the manufacturer's recommendations.
The application of enamel spray gun has a number of its advantages. We easily get a smooth and even surface with low material consumption and without any special effort. But for this purpose it is necessary to work as a professional tool.
Spray cans will not give the desired result. Practice has shown that it is more rational to solve the issue comprehensively. Namely - to do the starting coating with a brush, and finishing with a spray gun. So you are guaranteed the perfect new bath cover.
Restoring an old bath with acrylics
Ten years ago, the restoration of the old bath was possible only by painting with enamel. Today, another alternative method has emerged for restoring the damaged surface layer of a bath bowl using modern material - liquid acrylic. With such material, it is possible to easily transform your outdated plumbing yourself in just a few hours and increase its operational life by another ten years.
The advantages of acrylic in painting
Acrylic is a unique material. Due to its properties, the old worn-out sanitary ware is turning into a new one before our eyes, as if from a store. The material has excellent mechanical, chemical and decorative qualities. Excellent quality for the device surface baths have it goodanti-slipproperties.
To carry out the reconstruction with acrylic, it is not necessary to disassemble the facing tile and the bath tank, which greatly simplifies and speeds up the process. Most often for the work of this category is used liquid or bulk type of acrylic called Stakril, etc.
The advantages of these funds include:
- good fluidity for easy and uniform application of the layer;
- perfect smoothness of the resulting surface, without flaws, bubbles and roughness;
- low thermal conductivity, maintains the temperature of the water for a long time, there is no foreign smell;
- ease of operation and care, sometimes it is enough to wash with soapy water;
- high strength and wear resistance of the acrylic layer;
- Whiteness and excellent gloss persist for a very long time.
The composition of the material consists of two components - directly acrylic and a special hardener, which when combined form a very dense, reliable film with a thickness of 3 to 7 cm.
Before applying a new acrylic surface layer to the bath, similar preparatory procedures are carried out as in the case of enamel painting. The old surface is well treated with sandpaper, wash off the dirt, degreased with a solvent or soda, if necessary, treated with car putty and proceed directly to the treatment.
Conducting technology "bulk bath"
This restoration technology is suitable for acrylic and enamel cast-iron baths.For work on their own, it is necessary to prepare an appropriate acrylic composition, a plastic container of up to 1 liter capacity, a small metal spatula and a flashlight for easy quality control.
The whole technology of the filling bath consists of the following items:
- The mixture is prepared according to the instructions of the two components. Part of the solution is poured into the prepared plastic container for direct casting of acrylic.
- A small neat stream of liquid acrylic from a glass is poured around the perimeter of the upper contour of the bath. Spatula composition starts under the edge of the tiles.
- Pour the coating should drain to half the walls of the bath.
- During the work it is not necessary to use brushes and rollers.
- The lower part of the walls of the bath and its bottom is poured when passing through the second circle of the helix, maintaining a layer of 5 mm.
- Excessive mixture flows through the drain into the exposed pan.
If they are formed during work, they do not need to be corrected; after drying, they will finish everything themselves. During the restoration of acrylic one cunning is observed - the working surface must be warm. For this pre-bath is filled with hot water for 5-10 minutes.
After draining the surface thoroughlydriedcotton cloth and finally dried with a hairdryer. Prior to painting and during the process, the ingress of moisture to the surface is unacceptable, since acrylic adheres to a wet surface poorly. Acrylic hitch is carried out mainly due to the roughness of the base and the integrity of the design of the material itself.
If the acrylic coating is leaking, the water will quickly destroy it from the inside. To prevent such consequences, you can use an additional layer of acrylic. The thickened surface gets good operational durability. It is advisable to carry out the entire process of pouring gently, but quickly, as the acrylic seizes and loses fluidity.
The technology of pouring acrylic ideally should take about 2-3 hours no more. After complete polymerization of the finished layer after 1-6 days a drain is connected and the bathroom can be used.As can be seen from the above, such repair of the old bath is not difficult and affordable for almost everyone, even those far from construction.
Alternative to painting the bath
This is how people call the restoration of the surface of an old bath by installing an acrylic liner. The essence of the method consists in the installation of the finished liner of acrylic, fully corresponding to the configuration of your bath. In terms of performance, this method is the easiest. No need to prepare the surface to degrease, grind, dry.
But there are some nuances:
- fitting the liner along the perimeter;
- the surface of the bowl is treated with sandpaper, since it is necessary to increase the roughness of the base;
- special adhesive polyurethane is applied from the sides and down the bath;
- the sides and body of the liner are tightly crimped to prevent the formation of voids between the surfaces.
You can use the plumbing and connect the siphon after 5-6 hours. Pay special attention to matching bath profiles and liner, otherwise repair is not possible.This method of restoration, though the most simple, but at the same time the most expensive of these. To guarantee a good result, weigh your options and choose the most affordable way to restore your old bath.
