Grout Color Sealing
Grout Color Sealing creates an impenetrable barrier to soil and liquids and at the same time making the grout completely uniform in color. Having a barrier makes clean up faster and easier since the porosity of the grout has been covered with a sealed color coating.
In reality, not all grout cleans up to the appearance of when it was new. Sometimes there are stains that simply do not come out 100% or it may only return back to 95% of its original color.
In addition, if you are tired of your grout color and just want a different look, grout coloring is a solution.
Grout coloring does have its cons. Grout color is a coating and like any coating, it will eventually scratch and wear out and the original grout color will be exposed. Color sealants remain 1-2 years before having to be reapplied. And once you apply the new color, you can not completely strip it off. You will have to keep coloring it approximately every 2 years.
