The porous floor of concrete flooring permits water and soluble contaminants to penetrate right into a construction, which may result in untimely degradation. The degradation of concrete flooring can manifest in efflorescence, laitance and bodily defects similar to cracking and spalling. Concrete ground coatings can shield it from degradation by offering abrasion, stain, chemical and freeze/thaw safety.

Typical coatings that may be efficiently specified and used for concrete flooring embody acrylics, epoxies, polyurethanes, polyaspartic polyurea and specialised elastomeric coatings. It must be famous that alkyd based mostly coatings ought to by no means be specified for utility to concrete, for the reason that alkyd resin could chemically react with alkaline concrete compounds and moisture, resulting in saponification. This response transforms the resin right into a tender materials that no loner capabilities as a coating and supplies little safety to the concrete substrate. stained concrete floor installers in Houston

Acrylic coatings/sealers are usually a number of mils thick and are utilized 2 or three mills per coat. They’re both water based mostly or solvent based mostly compounds. Normally solvent based mostly acrylic sealers are utilized in exterior purposes whereas water based mostly acrylic sealers are utilized in inside purposes. A wide range of epoxy coatings can be utilized for coating concrete. typical epoxies are multi part supplies with a polyamide or amine curing agent. Polyamide epoxies are identified for possessing higher flexibility and water resistance, whereas amine-cured epoxies sometimes supply higher chemical resistance. Epoxy methods are often utilized in a single to a few coats at an utility thickness of a number of mils per coat. Thicker-film epoxy coatings, similar to these based mostly on epoxy phenol novalac resins are additionally used on concrete. Novolac epoxies are extra typically used for the aim of offering chemical resistance. Epoxy coatings must be topcoated with a end coat of a unique resin chemistry, since they chalk / amber in daylight. Sometimes they’re coated with polyurethanes.
