Understanding Sandblasting And Painting Processes

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 used for cleaning surfaces of various forms of dirt such as dust, mud, mold, and old paint among others. It can be used to clean both big and small objects and surfaces. Examples of things it can be used on include cars, floors, walls, ceiling boards, roofs, windows, animals, trees, and household equipment. It requires some experience and skills to be able to save on abrasive, water, and time.

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 equipment can be fueled by different sources of fuel such as electrical power, gasoline, diesel, and petrol. The power unit consumes the fuel to provide the required power to run other components of the machine. The air compressor sucks atmospheric air and pressurizes it to a high level. Pressurization is meant to give the air the energy to propel the abrasive for cleaning the object being sandblasted.

The nozzles are usually operated by the individuals operating the machines. The individuals direct the nozzles to face the areas that are being etched or cleaned. This implies that the amount of time, abrasive, or water is used on the task relies on the efficacy of the operators. Experienced operators tend to produce superior results in a shorter time frame. That is the cause it is advisable to hire a corporation that has experience in sandblasting.

After the surface is well prepared, the actual painting job can start. Powder coating is a current method of applying paint on an item and if applied properly, it produces nice results. It has many advantages over the conventional paint. First, need for a solvent medium to keep the paint in a solution form is not necessary. The powder remains in a dry form and may be applied up to a thick layer without sagging or running.

As part of the preparation, all elements that do not require to be painted must be removed from the spot. Once the paint has been applied to the needed level, the object must be put through a curing exercise which is same as drying in ordinary painting. Curing should take around fifteen minutes under oven warmth. Flameless heat sources achieve the curing in a perfect way.

Sandblasting and painting are services provided by several companies. Most service companies in this field have most recent equipment necessary for the job. For people who do not have the equipment or the expertise to do the job, service firms are a good option.
