Understanding The Process Of Sandblasting And Painting

By Grace Rivas


Sandblasting and painting are two activities that go jointly in decorating surfaces. Sandblasting refers to the propulsion of fine specks of material at high velocities towards surfaces for purposes of etching or cleaning whereas painting is the application of coats on an area. From the definitions, it clear that sandblasting is carried out before painting. Blasting prepares the surface for paint to bond perfectly with it after application.

Blasting is applied in removing various types of dirt like mold, old paint, dust, and mud among many others. It might be utilized to wash both small and large surfaces and objects. The examples of surfaces that can be cleaned using this process include cars, floors, walls, roofs, windows, trees, household equipment, animals, and ceiling boards. It requires skills and some experience to save on time, water, and abrasive.

The activity of abrasive blasting is performed using a machine referred to as an abrasive blaster. This machine is made up of various elements that work together to attain a common aim. The various components include power units, abrasive nozzles, hoses, and air compressors. The hoses have tiny openings to assist in increasing and sustaining the pressure with which abrasives emerge from the equipment.

The blaster appliances may be fueled with different fuel sources like diesel, petrol, electrical power, and gasoline. The power units consume the fuels to give the energy necessary to run other parts of the appliance. The air compressors suck the atmospheric air and compress it to high levels. Pressurization is designed to give air power to push abrasives for cleaning the items being sandblasted.

The nozzle is usually handled by the individual operating the machine. The individual directs the nozzle to face the place that is being cleaned or etched. This implies that how much water, time, or abrasive is spent on the task depends on the effectiveness of the operator. Experienced individuals tend to produce better results within a shorter period. That is the reason it is best to hire a company with experience in sandblasting.

After the surface is prepared, the actual painting work can begin. Powder coating is a modern method of applying coat on an object and if applied well, it produces elegant results. It has several advantages over the traditional paint. First, there is no need for a solvent medium for the paint to remain in a solution form. The powder stays as a dry powder and can be applied in thick layers without running or sagging.

As part of preparation, every item that does not need to be coated must be taken away from the spot. After the paint is applied to the necessary level, the article must be undertaken through curing process which is similar to drying in traditional painting. Curing can take around 15 minutes under oven temperatures. Flameless sources of heat perform the curing perfectly.

Sandblasting and painting are two services rendered together by several corporations. Most service businesses in this line of work have most current machines necessary for the work. For individuals who lack the right expertise and the equipment to perform the task, service companies are a nice option.
