Today, many of us are faced with this type of finishing work, such as painting. Paint is one of the most durable types of coatings that are very difficult to remove from any surface. However, very often there is a need to remove the paint from the metal in order to repaint it in a different color. Cleaning the surface manually is very difficult and time consuming, and it is not always possible to do it perfectly. Therefore, to clean the surface come to the aid of chemical means for removing paint from metal. In stores, solutions are presented that contain various components, some of them can have a negative effect on the body.
general information
The chemical method of removing paint is one of the most effective available today. It is based on the use of solvents and various solutions based on chemicals. They are sold in many stores, and their cost is relatively low, so most people prefer to use chemistry to remove coatings.
Varieties of solvents
The following types of chemical washes are on sale today:
- A modified metal paint remover designed to effectively remove most types of paint coatings.
- Universal washings - perfectly cope not only with fresh paint, but also with outdated layers. In addition to paint, they well wash away putty and primer mixes.
- Means for removing powder paint from metal - chemicals that excellently dissolve paints made on the basis of polymers.
- Conventional solvents - do a good job of removing a not very old paint layer from metal products.
- Combined chemicals - very fast acting.
- Multifunctional solutions.
The choice of a chemical agent for cleaning metal surfaces from paint depends on what purpose you need it for, so it is recommended that you carefully read the instructions for use before buying.
The principle of action of chemicals
The metal paint remover contains active ingredients that soften the structure of the paint, as a result of which the coating loses its strength and adhesion to iron, making it fairly easy to remove.
Chemicals begin to act very quickly, but the effect achieved remains for a short period of time. Therefore, when removing old paint or a very thick coating layer, it is not always possible to have time to clean the metal surface, which may require multiple washing on the surface to be treated.
If you want to reduce financial costs for the purchase of chemicals and for this purpose you are looking for the best tool for removing powder paint from metal, then you should buy those washes that contain substances that create an impermeable film that slows down the evaporation of the solvent. However, when using such tools, there is a negative side, which consists in the fact that substances that create an impermeable film can remain on a metal surface, which deteriorates its adhesion to paint materials. Therefore, after removing the paint, it is recommended to thoroughly wash the surface with any detergents.
Modern chemical solvents
A modern tool for removing old paint from metal contains special additives that give it a gel-like consistency, giving it the following advantages:
- solvent evaporation does not occur so quickly;
- chemicals are less toxic;
- solvents do not run off the surface, so they can even be applied to the ceiling.
After applying modern solvents to the paintwork, they completely soften it in just 25 minutes, after which the paint is very easily removed from the metal base.
Consumption
What is the consumption of Prestige paint remover? This is a very topical issue that interests many people no less than the performance characteristics of solvents. And this is not surprising, because regardless of the cost of chemical washes, if their consumption is small, then the financial costs will be insignificant. However, the whole difficulty lies in the fact that it is very difficult to accurately calculate the consumption of softeners made on the basis of chemical mixtures. The thing is that the amount of solvent required to completely remove the paintwork depends on many factors.
Optimum is considered such a means for removing paint from metal, which effectively copes with its task with a layer thickness equal to the thickness of the paint. Proceeding from this, it follows that for a complete cleaning of a metal surface, as many cans of rinse will be required as many cans of paint were spent on painting an iron product.
How to work with chemical washes?
To quickly and with minimal effort remove paint from a metal surface, follow these tips and tricks:
- Before applying the solvent, the surface must be thoroughly cleaned.
- It is best to apply a wash with a spray gun. This will allow you to evenly distribute the product over the entire surface.
- After applying the solvent to the iron structure, it should be covered with a film to prevent the access of fresh air.
- After 30 minutes, the film is removed and you can begin to remove the paint. If the paintwork is softened poorly, then the chemical means for removing paint from the metal is applied repeatedly.
In addition, before starting work with washing, it is imperative to familiarize yourself with the operating instructions.
Solvent Safety
Most chemical solvents contain various substances that are dangerous to humans. Evaporating, they can get into the respiratory system, as a result of which you can feel sore or burning in the throat, feel bouts of nausea or lack of air, severe headaches, dizziness, and much more. Therefore, when working with them, you should use a respirator.
In addition, it is forbidden to allow chemical washes to come into contact with the skin and eyes, therefore, clothing that completely covers the body and limbs, rubber gloves and construction glasses should be used during work.
As it turned out, removing paint from metal using chemicals is easy. The most important thing is to choose the right solution and adhere to safety precautions.
