Grout Repairs
There are a few options for grout repairs. A simple assessment will quickly determine the most practical approach; whether a simple re-grout will do the trick, targeting only the problem areas or an entire re-grout is necessary. Both processes may be wonderfully enhanced by the application of epoxy grout stains.
Re-Grout
If substantial areas of structurally sound grout exist, the faulty grout can be removed via hand-held tools and machines. Once the area has been thoroughly vacuumed to remove any remaining debris, the problem joints will then be re-grouted. Although this is the quickest and easiest of grout repairs, it’s very difficult to match the existing grout colors, even if the original grout is still available. As is the case with any organic materials, an aging process naturally occurs; changing its appearance. The best remedy is a blend of several grout colors to match the primary grout as much as possible. This seemingly simple step can be tricky and definitely takes an experienced, artistic eye. Color perfection should not be expected with this re-grout technique.
Epoxy Grout Stain
If a flawless finish is desired, choose a complete regrout or an epoxy grout stain for a consistent, even surface.
If grout is discolored, chipped, or missing in small spots but mostly sound, a simple re-grout can fix it. With epoxy staining, perfect color matching isn’t necessary, since staining the entire area creates a uniform, even look.
For a modern update without re-grouting, epoxy stain is ideal. With a wide range of colors, outdated tile can be quickly transformed into a vibrant, attractive surface.
Each grout joint is hand-painted with your chosen color, left to dry for about an hour, then gently washed. After 24 hours, the epoxy stain cures to a sleek, durable finish—no sealant needed.
Grout Replacement
Before (left): This tiled bathroom was installed satisfactorily, but the grout was substandard. The installer used non-sanded grout and then tried to resolve the issue with urethane or epoxy grout, which was smeared everywhere. (Non-sanded grout should only be used with 1/8" joints or smaller, as it does not hold enough to fill larger joints adequately and is notoriously weak.) The bathroom looked horrible and created a restoration nightmare. The homeowner was told by several professionals that the entire job should be torn out and re-installed with new tile. Of course, this would have cost her a lot of time, money, hassle, and grief. When she called NBR, everything turned in a positive direction.
After (right): NBR bid the job for 70% below the cost of demolition and re-installation. The grout was removed, which was no light task due to the density of the urethane/epoxy material, and then the entire bathroom was re-grouted with Laticrete True Color. The homeowner is ecstatic with the clean/crisp results! Good as new and talking of taking a trip to Italy!
