Epoxy Grout is a kind of grout that one uses for floors and stone installations. Unlike the usual cement-based grout, it is made up of resin and hardeners. Normally it appears as a two-part mix that you combine just before use.
Some types form three-part systems that add resin with a sandy grout filler. The chemical process that starts after blending of the parts cause the hardening, rather than depending on drying like cement grout.
Epoxy Grout: What It Is and When to Use It
The main benefit of Epoxy Grout is its extreme strength. It forms tough, solid joints that do not allow water, stains, chemicals or wear to get through. One does not need to seal it unlike cement grout.
It does not shrink, no crack no dull or spread mold. Its finish resists water damage and stone wearing. Because of that it works for wet places, heavily used floors, business kitchens, pools and similar spots.
Some known brands of Epoxy Grout are Laticrete Spectralock Professional Premium, Mapei Kerapoxy, TEC Accucolor and Bostic CEG Lite. Spectralock Professional Premium is made up of three parts and one commonly rates it as the eaisest to work with. It includes wash packets for the final cleanup.
Mapei offers also Flexcolor CQ, that well fights against stains from factory water, without leaving marks after fast wiping.
One must recall that Epoxy Grout is more difficult to work with than average grout. It hardens very quickly, so apply only that much, as far as you can shape and clean inside some minutes. It is not soft.
Having the right tools is key. A grout float, gloves for grouting, a mixing drill, corner roller, sponges and lint-free scraps all help. Metal and silicone finishing tools can well shape the joints, even so metal ones you test first on a small hidden bit too escape hurting the floors.
Epoxy Grout costs more than the standard. You should plan before giving the price to a client. Even so for bathrooms, kitchens, backsplashes and places where cleaning is a priority, the higher price can prove its value.
Cement grout in a bathroom soon looks dirty because of stains and mold, even if one sealed it.
Even so not all think that Epoxy Grout always must be used. For a typical home shower with good airflow and usual cleaning methods, regular grout with good sealer can work well. Epoxy Grout does not beat cement grout, if the installation itself is weak or badly taken care of.
Some products sold as Epoxy Grout are actually resin-modified cements, socontrol the exact mix before purchase is a wise idea.
