How to use metal polishing compound professionally
Use of metal polishing compound
Metal polishing compound is an essential product in the finishing and maintenance processes of metal surfaces. It is used both in industrial environments and in artisanal applications, thanks to its ability to remove impurities, smooth surface defects, and provide a uniform, long-lasting shine. In addition to improving the visual appearance of the piece, this type of compound also protects against corrosion, wear, and oxidation, thereby extending the service life of the treated metal.
There are different types of compounds, specifically formulated for each need: from aggressive pre-polishing to mirror finishing. Understanding their characteristics and knowing how to apply them correctly is essential to achieving a professional result without compromising the integrity of the surface.
In this article, we explain in detail how to use metal polishing compound, the different types available and when to use each one, as well as presenting the complete range of professional compounds offered by Abrasteel, a benchmark in the industrial abrasives sector.

What is metal polishing compound and what is it used for?
Metal polishing compound is an abrasive compound that can be supplied in solid or liquid form, used to improve the surface finish of different types of metals. Its formulation may include metal oxides, fine abrasives, waxes, or greases, depending on whether a more aggressive action (pre-polishing) or a high-gloss result (final polishing or buffing) is required.
These compounds work by removing microns of material from the surface, which allows to:
- Remove oxides, stains, and small imperfections.
- Reduce roughness and improve tactile smoothness.
- Achieve decorative effects or a mirror finish.
- Prepare surfaces for additional treatments (varnishes, anodizing, coatings).
- Extend the service life of abrasive tools on non-ferrous metals (e.g., aluminum, brass, copper).
The use of polishing compound is common in sectors such as the metallurgical industry, automotive, jewelry, metal furniture manufacturing, restoration of antique pieces, or interior design, among others.
The correct choice of compound, its format, and the application method are key to achieving a uniform, safe, and efficient finish, especially in industrial projects where consistency and performance are required.
Types of polishing compounds available at Abrasteel
At Abrasteel, we offer a specialized range of metal polishing compounds, formulated to effectively meet the different stages of the polishing process and the requirements of each type of material. This selection includes options in both solid and liquid formats, suitable for industrial applications as well as more artisanal tasks.
Solid compounds
Blue compound
Recommended for medium polishing tasks with a glossy effect. It provides a smooth, uniform finish on metals.
White compound
Ideal for dry polishing. It delivers a long-lasting, high-quality shine on metal surfaces.
Pink compound
Specifically designed for pre-polishing, providing cutting action and an initial level of shine.
Green compound
Perfect for greasy polishing, providing a deep and durable finish on a wide variety of metals. Perfect for greasy polishing, providing a deep and durable finish on a wide variety of metals.
Pumice paste
Suitable for high-quality greasy polishing, effectively preparing surfaces before polishing.
Greasing compound
Widely used in processes with abrasive discs or belts on non-ferrous metals. Improves performance and reduces premature wear.
Liquid compounds
Liquid polishing compound
Suitable for the final polishing stage. Allows mirror finishes to be achieved, especially on stainless steels or ornamental parts.
Liquid compound for polishing and buffing
Performs a dual function. First, it prepares the surface with a fine cut and then leaves it ready for the final high-gloss finish.
How to choose the right metal polishing compound
Selecting the right polishing compound is key to achieving the desired finish in every project. Depending on the type of metal, the stage of the process, and the expected result, Abrasteel offers specific solutions tailored to each need.
Type of metal
Not all metals respond the same way to the polishing process. Some considerations:
- Aluminium and soft metals: They require less aggressive compounds such as green compound or greasing compound, which help preserve the integrity of the material.
- Stainless steel and hard metals: They perform best with blue, white, or pink compounds, depending on the level of cutting or polishing required.
Initial surface condition
Before applying any compound, it is necessary to assess whether the surface presents:
- Burrs, oxides, or imperfections: It is advisable to start with a pre-polishing compound, such as pink compound or pumice paste.
- Already treated or matte surface: A liquid polishing compound can be used directly to achieve a mirror finish.
Desired finish
- For a glossy finish: Use white compound or liquid polishing compound as the final stage of the process.
- For a satin or intermediate finish: Medium-cut compounds such as blue compound provide a balance between shine and texture.
Most suitable format
- Solid compounds: Recommended for continuous processes in workshops or industrial environments, used with polishing wheels or brushes.
- Liquid compounds: Easy to apply and fast-acting, ideal for detailed or restoration work.
Techniques for applying metal polishing compounds
Proper application of metal polishing compounds makes the difference between a professional finish and a poor one. At Abrasteel, we recommend following a series of key steps to achieve maximum performance in every process, regardless of the type of compound used (solid or liquid).
How to properly apply polishing compounds?
Select the appropriate accessory
Use discs, brushes, or felt wheels compatible with the chosen compound. Sisal cloth or felt wheels are ideal for applying solid compounds, while liquid compounds can be used with soft pads or foam applicators.
Apply the compound progressively
If it is a solid compound, bring it close to the rotating wheel to load it by friction. If it is liquid, apply a small amount directly onto the accessory or the part.
Avoid excess: an adequate load is sufficient to achieve effective results without clogging the material.
Maintain constant, controlled pressure
Let the tool do the work. Do not apply excessive force: too much pressure can cause overheating or marks on the surface.
Work on large areas using uniform movements
Make uniform passes and avoid staying too long on the same spot. This ensures a smooth, mark-free finish.
Assess the result before switching compounds
In multi-stage processes (pre-polishing, polishing, and buffing), thoroughly clean the surface between steps and change the wheel or accessory to avoid mixing different compounds.
