Car Parts & Accessories: Grinding paste Video Guide

Grinding paste is used for car care as well as for the care and surface treatment of metals and lacquers. Since abrasive paste is available in different grit sizes, the removal of the surface is individual and can range from a slight polishing effect to roughening the substrate before a new coating is applied. The use of abrasive pastes has established itself above all in car paint shops and tuning as well as in paint care. Grinding pastes have a sandy grain, which is integrated in a caring and greasy liquid and applied with a sponge. If the varnish is not to be removed but polished, a fine abrasive paste with minimal grain size is recommended. This removes dirt from the surface of the varnish and thus provides a shine which, in combination with a polishing cloth, receives its finish. Grinding paste can be like fine flour, like classic sand or with the grinding effect of roller split. Depending on the application, it is therefore necessary to concentrate on the grain size in order to achieve the desired effect.

A grinding paste is used for surface removal and surface finishing. It removes everything from the coarse dirt to the paint, which lies within its functional range and should be removed by means of the grain size and the appropriate tool. In the case of stone chips in the paint, unevenness caused by flat or deep scratches and a new desired paint finish, abrasive paste can serve as an alternative to classic paint removal by heat. While the processing of small areas is carried out manually and advised with sanding paste and a sponge, the entire car paint is removed with an electric sanding device and the paste. An electric grinding machine with a very fine sponge and floury grinding paste can also be used for high-gloss polishing. To ensure that the machined surface looks uniform and is ground identically at every point, grinding is carried out in circular movements and at a constant speed. Grinding paste forms the layer between the grinding sponge and the surface to be machined. It spreads well and enables even and constant sanding of rust, old paintwork, burnt-in dirt residues and other materials on surfaces. Sanding pastes are also important in woodworking, where they are mainly used in fine grain form for the preparation of solid wood furniture and are used according to the same principle as for polishing varnish.

By using abrasive paste in combination with the correct application and optimum grain size in relation to the result, an even sanding of surfaces is achieved. The application is simple and can be done with an electric grinder for larger surfaces, or with a special grinding sponge for smaller surfaces. Due to the different grit sizes, grinding paste can be used for different abrasion strengths of surfaces. Very fine grains polish optimally and make even old car paint shine like new. A coarse grain is mainly used if the varnish is to be roughened and prepared for a new varnish or if a piece of furniture is to be varnished or glazed after sanding. Grinding paste has no disadvantages if the right grain size is chosen and a high-quality product suitable for the respective application is chosen at the time of purchase. If the abrasive paste is applied manually and is not used in combination with an electric grinder, a lot of attention must be paid to uniform pressure and constant movements. Otherwise, the result could be wavy and with different surface characteristics and present a problem before the new processing.

When sanding paste is applied to paint or sensitive furniture, the surface treatment product should be chosen with care and attention. Grinding pastes produced in the EU are subject to strict control and have the grain size indicated on the packaging. Those who buy grinding paste cheaply not only proverbially buy twice, but also cause visible damage to the surfaces. Evaluations by other buyers and helpful tips from workshops support the purchase and ensure that you choose a high-quality abrasive paste with the necessary grain size. Under no circumstances should grinding paste be chosen as a savings offer and selected on the basis of price. Stiftung Warentest is also a contact if you want to choose the winner of the comparison and do not want to compromise when buying grinding paste. Numerous manufacturers and brands have produced a variety of high-quality abrasive pastes in various grit sizes.
