General information about abrasive paste

Abrasive paste is used for car care, as well as for the care and surface treatment of metals and paints. Because it abrasive paste In different grain sizes, the removal of the surface is individual and can range from a slightly polishing effect to the roughening of the substrate before a new paint job. The application of grinding pastes has established itself primarily in the car body painting and tuning as well as in the paint care. Sanding pastes have a sandy grain, which is integrated in a nourishing and greasy liquid and with a spongeis applied. If the varnish is not to be removed but polished, a fine finish is recommended abrasive paste with minimal grain. This frees the paint surface from dirt and thus ensures a shine, which gets its finish in combination with a polishing cloth. abrasive paste It can be like fine flour, like classic sand or with the abrasive effect of rolled split. Depending on the application, it is therefore necessary to concentrate on the grain and thus achieve the desired effect.

Function of abrasive paste

An abrasive paste is used for surface abrasion and surface work. It removes everything from the coarse dirt to the paint, everything that lies within its functional range and by means of the grain and the corresponding Toolshould be removed. In the case of stone chips in the paint, unevenness due to shallow or deep scratches and a new desired finish, abrasive paste can be used as an alternative to classic paint removal by heat. While the processing of small areas is carried out manually and advised with abrasive paste and a sponge, you wear the entire car paint with an electric grinder and the paste. Even with high-gloss polishing, an electric grinding machinewith a very fine sponge and floury grinding paste are used. In order for the machined surface to look uniform and to be ground identically at each point, the grinding takes place in circular movements and constant speed. Sanding paste forms the layer between the sanding spongeand the surface to be processed. It spreads well and allows an even and constant sanding of rust, old paint, burned-in dirt and other materials on surfaces. Also in the woodworking grinding pastes are not insignificant, where they are mainly used here in fine grain for the treatment of solid wood furniture and polished according to the same principle as polishing the paint.

Advantages and disadvantages

In combination with the right application and optimum grain size, grinding paste achieves a uniform sanding of surfaces in terms of the result. The application is simple and can be done on larger surfaces with an electric grinder, in small areas but also with a special sanding sponge. Due to the different grain sizes, abrasive paste can be used for different abrasion strengths of surfaces. Very fine grains polish optimally and make even old car paint shine like new again. A coarse grain is used especially when the paint is roughened and prepared for a new paint job or a piece of furniture after sanding is to be painted or varnished. Abrasive paste comes without any disadvantages, provided that one chooses the right grain and decides on the purchase of a high quality and suitable for the respective application product. If the abrasive paste is applied manually and not used in combination with an electric grinder, you have to pay much attention to the even pressure and the constant movements. Otherwise, the result could be wavy and have different surface finishes and pose a problem before reworking.

Helpful tips for buying

When it comes to the paint or sensitive furniture with abrasive paste, the surface finishing product should be chosen with care and attention. Abrasive pastes manufactured in the EU are subject to strict control and wait with the grain size indicated on the packaging. Anyone who buys abrasive paste cheaply not only buys proverbially twice but also produces visible damage on the surfaces. Reviews from other buyers and helpful tips from garages help with the purchase and ensure that you decide for a high-quality grinding paste in the required grain size.
