Four Construction Methods of Fireproof Coating

Fireproof coatings are applied evenly on the surface of the construction object using tools and equipment during construction, but the methods vary depending on the type and properties of the coating. Blindly applying the coating will result in unsatisfactory effects. For different construction objects and fireproof materials of different properties, we use different construction methods to obtain the best coating quality. Below are the four coating methods provided by Zhan-Tuo Fire Protection.

The first construction method is scraping:

Frequently used metal or non-metal manual scraping tools such as fiberglass scrapers, horn scrapers, plastic scrapers, hard rubber pieces, etc., to remove various thick paste-like fireproof coatings or excess parts of gaps on the object surface.

The second construction method is roll coating:

Roll coating is generally applicable to wall construction. The roller is coated with paint, and then rolled back and forth on the wall surface to attach the paint to the wall. The roller we are talking about is a small hollow cylinder with a surface coated with synthetic fiber long fluff. There are two gaskets at both ends and a hole in the middle for a curved handle to pass through. Now with the improvement of technology, there are roller coating devices that use air compressors to transport the paint.

The third construction method is brush coating:

Brush coating is not only suitable for wall construction, but also for the surfaces of any other shaped objects. Most fireproof coatings can be applied using this method. Brush coating can easily apply the coating into the fine pores and gaps on the object surface, thereby enhancing the adhesion to the surface. However, the production efficiency is low and the labor intensity is high. Sometimes brush marks are left on the surface of the coating, affecting the decorative effect of the coating.

The fourth construction method is spray coating:

The paint is atomized by a spray gun and sprayed onto the surface of the object. The quality of the sprayed coating is uniform, and the production efficiency is extremely high. However, during the construction process, some of the paint is wasted, and the large amount of evaporated solvent in the mist is not conducive to the operator's health. The key equipment for air spray is the spray gun. According to the paint supply method, the spray gun is usually divided into three types: gravity, suction, and pressure, and according to the spraying capacity, it is divided into small and large models. For high viscosity coatings, a large-caliber nozzle should be selected, while for low viscosity coatings, a small-caliber nozzle can be used.
