Topical sealers are designed to provide surface protection, chemical and stain resistance by bonding and forming a film and protective barrier on the surface of the material. These type of sealers are not penetrating and will sit over and on the top of natural and engineered stone surfaces when applied.
It is important to note that topical sealers have a difficult time bonding to smooth surfaces, hence they should not be used on highly polished surfaces. In Australia, topical sealers are generally used for outdoor paving projects and are a very popular option for sealing matt to rough textured porous stone surfaces.
There are many advantages to using topical sealers. Firstly, the coating is very hardy, and can hold up very well against most wear and tear. Besides that, application for topical sealers are generally quite easy and can be attempted by most homeowners. In addition to that, many types of topical sealers can add gloss or lustre to the surface of your projects.
