Acrylic sealers are a good choice for those who want to seal such materials as concrete, masonry, and brick, protecting them from acids, oils, grease, salt, food stains, UV rays, and more. Contrary to what you may read elsewhere, acrylic sealers will not penetrate the surface of the material rather, they will form a substantive protective film over the concrete. It may help to think of an acrylic sealer as a raincoat, not allowing water through to the clothing, skin, or hair underneath. The sealers similarly beautify decorative concrete, enhancing the colors while curing and sealing the material for a number of years with its breathable film.
Water-based acrylic sealers are often a better choice than solvent-based sealers. Water-based simply means that the acrylic solids (the parts actually protecting the concrete) are suspended in water, rather than a chemical solvent, such as acetone or xylene. When applied to the concrete, the water spreads and eventually coagulates over the material, fixing the protective acrylic particles in place to repel the various weathering phenomena (e.g. rain, snow, sun, etc.).
While water-based sealers may not last as long as solvent-based, they are a significantly lower-risk alternative compared to the chemical sealers. Water-based acrylic sealers can be applied outdoors or indoors, as there are no harmful fumes to threaten ones health. Solvent-based sealers can only be safely applied in well-ventilated areas; any other type of environment risks severely adverse effects to ones long-term health.
Similarly, water-based sealers are not flammable, nor will they change the color of the material. Again, they can be applied indoors (for example, in basements) without worry of going up in flame their convenience often justifies their shorter life of application. In contrast, not only are solvent-based sealers hazardous to ones health, but they can always ignite, even from a mere spark, if applied in a poorly ventilated area.
If you have a project requiring a water-based acrylic sealer Cryli-Tek 5500 is a 100% acrylic formula that, when applied, results in a breathable film enhancing the concrete material to which it is applied. Simply clean the surface and easily roll or spray the sealer over the material for a durable finish that will keep the surface looking new for years to come.
