Understanding Sandblasting And Painting Processes

By Grace Rivas


Sandblasting and painting are two processes that go hand in hand in the decoration of surfaces. Sandblasting is the forceful propulsion of small particles towards surfaces for cleaning or etching purposes while painting is the application of paint on a surface. From the definitions, one should be able to understand that sandblasting is done before application of paint. It acts as a surface preparation initiative for the paint to bond properly with the surface it is applied on.

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 exercise of abrasive blasting is carried out using an appliance called an abrasive blaster. The machine comprises of various components that work together to realize a common purpose. The various elements include abrasive nozzles, hoses, air compressors, and power units. The hosepipes have tiny openings to aid in increasing and upholding the pressure and force with which abrasives come out of 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 preparation, all components that do not need to be painted should be removed from the site. Once the coat has been applied to the required level, the object should be taken through a curing process which is equivalent to drying in ordinary paint. Curing should take about fifteen minutes under oven temperatures. Flameless heat sources do the curing in an elegant way.

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.

  1. It's crazy how high powered these sandblasters are! We've been thinking of getting some sandblasting done to our house. Maybe we could repaint finally after too.

  2. I'm interested to learn that sandblasting and painting are usually used hand in hand. I've heard of some people using sandblasting to remove paint and other things. Hopefully, we can find something like this in our area. We really need to get a barn sandblasted so that we can repaint it. http://www.blastpro.com.au/services
