Sprayers and spray coating equipment is used to apply coating, paints, disinfectants, cleaners, fluids, chemicals, powders and other industrial materials to surfaces. There are many types of sprayers and spray coating equipment. Examples include paint spray guns, high-volume, low-pressure spray guns or HVLP spray guns, spray tanks, spray foam equipments, waterproofing spray equipments, and spray pumps. A paint spray gun blasts tiny particles of atomized paints, liquids, powders, or adhesives onto a target surface with high pressure. Unlike the paint spray gun, an HVLP spray gun employs a turbine motor to deliver large paint droplets with low nozzle pressure. An HVLP spray gun displays greater painting efficiency over a conventional spray gun by reducing the amount of paint wasted due to overspray. A spray tank is used to store paint required for spraying the paint onto a target surface. Spray foam equipment delivers paint froth using multiple-component proportioning equipment. For smaller applications, large-pressurized or pre-packaged cans can be used as spray foam equipment. Waterproofing spray equipment is used to apply a coating that ensures the dryness of surfaces such as the basement or foundation. The coating prevents water from seeping through the cracks on these surfaces. A spray pump is used to pump paint with the help of a high-pressure hose and is compelled to pass through minute tips, which split the paint into different types of spray pattern fans. Other sprayers and spray coating equipment are commonly available.

There are several ways in which sprayers and spray coating equipment function. Spray paint equipment reduces the amount of time required to paint per unit surface and is cost effective. A spray paint gun should ideally deliver 10 ounces of paint in one minute if the paint is blasted through 3/8 in. hose of length equal to 15 feet. While holding the spray gun, its distance from the target surface should be typically 8 to 12 inches. An HVLP spray gun usually provides higher transfer efficiency of up to 75 to 80 percent over conventional spray painting by drastically reducing bounce-back and overspray. The size of the tip of the HVLP spray gun determines the amount of paint delivered. A spray tank should provide larger capacity to reduce the amount of time required between refills. The surface of the spray tank should also be resistant from corrosion and chemical attack to ensure long-lasting durability. Spray foam equipment ideally comprises two proportioning pumps, which heat and proportion materials such as the isocyanate and polyol resin with the help of heated hoses. Spray foam equipment should ensure that these materials are placed separately throughout the process until they mix in the spray gun and are applied to the surface. A spray pump should provide facility for pressure adjustment to regulate the pressure used to blast the paint through the hose. Sprayers and spray coating equipment are designed and manufactured to meet most industry specifications.

Sprayers and spray coating equipment are used in many applications. Examples include performing spray-painting operations for horticulture, agriculture, shipyard employment, construction, and transport industries. As extensive exposure to such equipments cause health problems such as eye and skin disorders, nervous disorders, or respiratory disorders, sprayers and spray coating equipment should adhere to safety standards established by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA).
