Sandblasting stencils are vinyl or rubber stencils that adhere to surfaces and protect them from sandblasting. There are positive and negative stencils, and they can be used to etch designs on wood, concrete, and glass. They are available in home improvement and sandblasting stores and can be used for personalization and decoration. They are single-use or reusable and should be tested before use.
Sandblasting stencils are thick vinyl or rubber stencils used to make designs on wood, concrete and glass while sandblasting. Sandblasting stencils are typically a peel-and-stick design that allows the stencils to adhere to almost any surface and be easily removed when sandblasting is complete. There are two specific types of sandblasting stencils: positive and negative stencils.
A positive stencil is applied to a surface to protect the area from the effects of sandblasting. A negative stencil is used to protect the surrounding area from sandblasting while the design is etched into the surface. Kits containing both types of stencils are often available at home improvement and sandblasting equipment and supply stores.
Sandblasting is a method of removing the finish from a surface by shooting fine sand or other media from a high powered air hose nozzle. Occasionally, sandblasting stencils are used to etch specific designs or lettering into the surface of an object in order to personalize and decorate it. Available from a variety of manufacturers, sandblast stencils can be placed over a surface to be sandblasted by peeling a protective film from the adhesive-coated stencil backing. With the stencil in place, the blasting can be completed and depending on the type of stencil used, the stencil image is left on the surface of the object in either a positive or negative image.
Typical uses for sandblasting stencils are etching addresses on concrete, marble, or stone buildings or fences, as well as placing images or numbers on walkways, driveways, and glass windows. The effects of glass sandblasting often leave a frosted appearance. Using the sandblast stencils, lettering, artistic images or decorations can be placed on glass to highlight a business or home. Some vehicles are equipped with stencils to add a touch of personalization to the front and rear windows and glass of the vehicle by sandblasting. When sandblasting wood surfaces, the softer wood is commonly removed, leaving only the stronger fibers and creating a unique look.
Using sandblasting stencils on ordinary stone can create custom garden art, pet tombstones, and patios. Typical peel-and-stick vinyl sandblasting stencils are single-use products, while heavy rubber versions of the stencils can often be used repeatedly. Before using a sandblaster on any project, it is recommended that users test the air pressure on a similar object to ensure that no damage is done to the surface of the object or to the stencils.
