Did you know one of the best ways to remove varnish, painting and graffiti on a wall or surface is by using a stripper? Next, we will explain What is a paint stripper?, the types that exist, as well as their uses and recommendations to take into account.
This part is very important since Pickling is the use of a chemical that acts directly on materials and can be toxic in some cases, depending on their use or the surface applied. For example, some chemical paint strippers are very powerful and They can give off gases, so it is necessary to know when and how to use them. and avoid accidentally breathing them in.
Most paint strippers sold on the market come with recommendations for use by the manufacturers. Even so, we will detail their uses, recommendations and all the issues to take into account in order to know how to use this chemical product.
What is a paint stripper and what is it used for?
Stripping is the Removal of a layer of rust, paint or varnish by a physical-chemical process using a stripping product.
El A typical example of the use of paint strippers is to remove old paint from a wall or surface.The chemical action of strippers acts directly on the surface and the layer that covers it.
They work by breaking down the bond between the paint and the surface into small particles. Once the paint has been broken down, it can be easily treated and cleaned.
One type of stripper is solvents. The chemical action of these products allows them to act directly on the surface and the layer that covers it. Thus, through a chemical process The solvent interacts with the particles to be removed (from oxide or paint) and removes them thanks to its disintegrating power.
A stripper is a type of chemical that can be used to remove almost any coating from a surface, For example:
- Paintings.
- Products for coatings and finishes.
- graffiti.
- Oxide.
- Varnishes.
Paint strippers can also be used to clean wood and other porous surfaces. Depending on the type of paint stripper, its strength and composition, it can be applied in one way or another.
How to use a paint stripper and how many types are there?
Choosing the right paint stripper can be a difficult task if you don't know which type to choose.
The three types of pickling processes are divided as follows:
- Chemical process: Chemical strippers are usually acids or penetrating agents such as solvents with additives that dissolve in water to inhibit the chemical bonding of surfaces. They are used industrially and privately and for all types of surfaces: wood, paint, metals, etc.
- Mechanical or manual stripping: This type of stripper uses the mechanical action of sandpaper, granulated material or steel shot to bombard the surface to be stripped. If done mechanically, compressed air guns or steel brushes can be used. If done manually, granulated sandpaper is normally used.
- Electrochemical stripper and other types: This type of stripper combines a chemical and electrical process to break the bond of the substances to be stripped.
Most of the products and strippers sold on the market are chemical. These are divided as follows:
- Caustics: These strippers are solutions of water with potassium hydroxide and lye.
- Solvents: These products remove paint by dissolving or softening the bond between the film and the substrate.The most common are the methylene chloride and some esters.
- Biochemists: These strippers are different from the previous two and are divided into acids and oils.
The choice of one stripper or another depends on the type of surface and its industrial or private use. For example, biochemical and caustic strippers are the most recommended at the company level and for large surfaces.
Solvents are generally the most suitable for domestic use, although there can always be exceptions. The good thing about this variety of strippers is that they can be used to strip both interior and exterior surfaces, as long as they are not excessively oily or greasy.
How does a paint stripper work? When and how to apply it
Whether you want to remove old paint from interior or exterior surfaces, it is important to consider a few factors, including the following:
- The type of paint that the surface to be removed has.
- Budget.
- How the stripper works.
- And the extent of the damage to the paint and/or surface.
Paint and varnish layers are some of the most difficult substances to remove from a surface. Whether it is a basic paint or a very strong varnish, Most of these products become embedded in surfaces and are resistant to the action of a normal cleaner.
For this reason, strippers are used. The power of these products is their Penetrating and dissolving capacity capable of acting from the deepest part of the surface and remove the adhesion of the paints.
The operation of a stripper is simple. It is a chemical product in the form of a liquid or gel that penetrates a surface by capillarity and dissolves the substances adhered in the form of a layer on the surface or wall.
Some strippers may work better for certain types of paint and with certain types of surfaces, while others are not as effective. It is important to choose a product that offers the best possible results for your specific needs.
With that in mind, here are some of the most common types of paint strippers:
- Strippers for porous surfaces:
Cleaning paint or varnish from a porous surface requires a solvent with a high penetrating capacity. Another option is one with a high energy capacity and application, either vertically or horizontally.
Methylene chloride is the most common compound in this class of solvents. An example is our product Scop V Nf paint stripper with great cleaning power on all types of porous surfaces.
Simply use a brush or roller and spread the product in paste form over the surface to be treated. You have to let it act for the necessary time and then remove the paint or varnish.
- Strippers for all types of surfaces
Non-porous surfaces are easier to strip than porous ones. All-purpose strippers usually act by capillarity with a combination of penetrating and disintegrating compounds.
Both agents remove the bond from surfaces (paint and/or walls) and allow cleaning. If you are looking for a stripper for non-porous surfaces, our Paint stripper solvent for removing graffiti on smooth surfaces Is the best solution.
It is capable of removing graffiti and paint from any smooth surface such as glass, Formica, metals and walls. It works by spraying, brushing, dipping or spraying with a spray bottle.
Simply pour it over the surface and wait for an hour or a long time, depending on the amount of paint and the surface.
Whether it is a porous paint stripper or notIt is advisable to read the manufacturer's recommendations and wear a mask or face protection if working on closed surfaces.
Finally, it is advisable to choose a product that is suitable for each job and to use reliable commercial items from recognized brands.
With the explanation of how a paint stripper works and how to use it, as well as its recommendations and types, you now know everything you need to know to remove paint residue from any surface.
Removing paint or varnish residue will be easier and more effective. You will save a lot of time cleaning the walls.!
