subject: Silo Painting [print this page] Silos are very important structuresSilos are very important structures. Silos protect grain from insects and the elements. They may offer protection to the grain, but the structure itself also needs protecting. Protection in this case means silo painting. Silos are exposed to climate changes and temperature shifts, and the damp air and rain can cause them to rust. Indeed, it is crucial to do silo painting right.
The most significant factor to consider in silo painting is the paint. Before doing any kind of silo painting, one must choose the right kind of paint. For instance, one should stay away from epoxy paints; they do not work well for exteriors because they chalk and fade due to outdoor exposure. The paint chosen for silo painting must be tough enough to withstand the most severe of atmosphere conditions. Experts recommend a two-coat finish system to do the job. A good paint choice would be marine paints: they are known to withstand splash zone exposure. These paints are available from commercial ship and pleasure boat supply stores, which can also provide consumers with primers and topcoats in an assortment of colors. It is also possible to mix and match, or customize a finish system. Those who want to do so should choose a two-component epoxy polyamide zinc chromate primer and a two-component polyurethane enamel topcoat. These kinds of primer and topcoat are sold in shops which supply architectural paints.
Before silo painting, there are some things that has to be done. If there is rust, they should be removed first. The old paint should also be eliminated. There are various methods to remove these layers, and these include mechanical abrasion through sanding, blasting or wire brushing. A substrate must be painted immediately after the removal process; this is to avoid rusting and another case of paint failure.
