Spray sealants protect surfaces from moisture and chemical damage. They come in various sizes and types for different projects, and some have UV protection or color pigments. They are used to protect inks and prints from smudging and water damage. Gloss and matte options are available.
A spray sealant is a liquid or foam barrier applied to surfaces to protect them from the elements. Spray sealants are made by combining plastic polymers that adhere to a surface and to each other to create a solid layer of defence. Custom spray sealant formulations are manufactured for specific surfaces in small-scale, commercial, and large-scale industrial applications. Sealing a surface with sealant prevents much of the moisture and chemical seepage that can cause damage. Painted and unpainted surfaces have microscopic fissures and cracks that can be filled by applying one or more coats of the correct variety of spray sealant.
Sealant sprays come in many sizes and types to meet specific project needs. Sealing smaller areas is commonly done with small, handheld spray cans. Larger areas require a large volume of sealant packaged inside pressurized refillable cylinders. Reading the label of an aerosol sealant carefully before applying it is an important step in ensuring that it is safe for use on the intended surface. Some foaming sealant sprays have two liquid components that react to generate a thick foam when combined in the spray tip at the last moment before application.
The layer of protection provided by a spray sealant usually becomes clear or slightly opaque once it is allowed to dry completely. Clear sealants applied to a vehicle’s paintwork allow the paint color to show through extending the longevity of the original shade. The added cost of using a sealer is an investment in the future condition and appearance of the protected surface. Some varieties of spray sealants have an ultraviolet additive that blocks nearly all of the sun’s harmful rays. Permanent pigments can be added to a liquid sealer to turn it into a colored polish.
Many graphic artists and printers use spray sealers to protect applied inks, varnishes, and pigments from smudging and water damage. Sealant sprays are sometimes applied to high-quality prints to prevent the ink from penetrating the paper and spreading to the surrounding area. Spraying the front and back of a sheet of paper has created a laminated layer that keeps the print sealed. Sealant should be applied from the manufacturer’s suggested distance to avoid oversaturation and streaking. Gloss and matte spray sealer options are available to leave the sealed page glossy or matte depending on your project needs.
