Basic Surface Preparation Techniques For Painting Steel Mills

Steel mills are among the common surfaces rarely painted due to nature of the operations taking place around and within the setting. Most of the surfaces herein are exposed to different conditions, which at times, happen to be unfavorable. However, the hardiness of materials used for making steel mills enables them to endure such circumstances. Painting is, however, one of the ideal ways of enhancing the longevity, performance, and appearance of these surfaces. Some of the basic techniques you used in surface preparation of steel mills include the following;

Captive shot blasting – It refers to the surface preparation method, which blasts the surface using small steel balls at relatively high velocity. It is ideal for removing any form of contamination as well as providing a textured surface. This is in preparation for applications of sealers or coatings overlays. It is an ideal technique to remove previously laid coatings since it produces comparatively little airborne dust or contamination.

Scarification – It is regarded as one of the most aggressive, faster, and expensive surface preparation method for steel mills. It is highly recommended to eliminate debris and deposits on this surface in preparation for painting. It uses scarifies to remove the top layer of debris hence exposing a fresh and clean surface. When using this technique, it is necessary to apply dust prevention, especially in steel mills, where there is a presence of machinery.

Diamond grinding – It is among the most economical surface preparation method for painting steel mills. It involves rotation of one of multiple abrading disk or stone fitted with the diamond cutting grain. It can produce a profile, which ranges up to 60 grit sandpaper finish to a highly polished steel mill surface. This method is vital in correcting irregularities such as faults and roughness before the actual paint is applied. It leaves a smooth profile, which is suitable for thin mill coating as well as sealer applications.

Power tool cleaning – It is an ideal method for removing deteriorated coatings, loose mill scale, and loose rust from steel mills. It cleans the surface to the same requirements and maybe a suitable alternative to scraping and wire brushing. However, it is always recommended to remove the dust and debris from the surface using chemical cleaning before using power tool cleaning.

Hand tool cleaning – It is usually in the form of ultra-pressure water blasting. This surface preparation method can remove different types of deposits and debris, such as loose concrete and mortar, among others. It is an ideal method because it dust-free, thus necessary in steel mills. However, you also need to ensure the surrounding has a better drainage system for the disposal of a large volume of water.

These are the primary methods you can use to prepare surface awaiting painting steel mills. As you can see, all are intensive hence requires a professional approach.
