How to Avoid Problems When Painting Paper Mills
When painting paper mills, you are likely to experience a few challenges, especially if you fail to put preventive measures in place. It is essential to know the basics surrounding painting of exterior surfaces for paper mills are related machinery. Avoiding different forms of issues when painting these industrial components vary depending on the problem. However, it is always ideal for preventing the problem and correcting it lest it reappears. Some of the common issues when painting these surfaces include the following;
Temperature blisters – They can show up relatively fats from within a few hours to a few days after paint application. These blisters usually appear in the topcoat of paint and are quite often where oil-based paints are used. It usually arises as a result of fluctuating temperature affecting the painted surface. Professional advice recommends refraining from using a thick coat and relatively dark colors when painting paper mills.
Staining – The cause of staining is moisture. Rusting metal is the typical source for staining. Secondly, chemical reaction and between moisture and the surface may also lead to color buildup on the paper mill surfaces. If there is any rusty part on the surface, it is advisable to hand sand and coat with rust inhibitor and finish coat. The ideal approach of preventing this element is by properly scrub, prime, and apply the suitable type of paint on the paper mill surface.
Cross-grain cracking – It is as a result of too many layers of paint or a single coating, which is seemingly too thick. Several layers of paint on the surface of industrial paper mills may result in uneven and interconnected patterns of cracks. Ordinarily, thick paint is unable to expand and contract within the surface of these industrial components. If the issue is not corrected, moisture may permeate the paint layers hence causing deeper cracking on the surface and deterioration.
Inter-coat peeling – This is another common problem you are likely to encounter when painting paper mills. It usually occurs as a peeling underneath whenever a fresh paint coat separates from the original coat underneath. The primary cause of inter-coat peeling is inadequate surface preparation or applying coat on a dirty surface. It can also arise as a result of incompatible paints hence causing them to peel away. The best technique to prevent this problem is to ensure you are using compatible paints. You also need to clean the surface to remove the dirt before applying the fresh coat.
Moisture blisters – Any form of moisture tends to affect painted surfaces. Vapor and moisture building up in an enclosed space tend to cause problems with exterior paint. Moisture penetrates paint hence forming blisters, which makes the paint peel. Moisture blisters tend to go through all paint down to the material surface of the paper mill. To prevent this from arising, it is recommended to ensure the paper mill is well-constructed using better techniques. The best approach to dealing with most of these challenges surrounding painting paper mills is by considering using an expert painter. And an expert at this point is Industrial Painting USA.
