Installing a glass tile backsplash can add a touch of elegance and visual interest to any kitchen or bathroom. However, choosing the right grout for glass tile is critical for achieving a beautiful finished look. The grout fills the joints between the individual tiles and becomes a visible part of the design. Using the wrong type of grout with glass tile can result in cracking, staining, and other problems down the road. Here is an in-depth look at the best options for what grout to use for glass tile backsplash installations.
Factors to Consider When Selecting Grout for Glass Tile
When selecting a grout for glass tile, there are a few important factors to take into account:
Flexibility
Glass tile is rigid and inflexible, so the grout used needs to have some flexibility to it. This allows the grout to absorb any shifting or movement that may occur over time without cracking or pulling away from the glass tiles. Flexible grouts are best for glass tile backsplashes.
Stain Resistance
Glass tile itself is stain resistant, but the grout is porous and can be susceptible to staining. Using a grout with maximum stain protection will help keep the whole backsplash looking clean. Opt for highly stain-resistant epoxy or urethane grout.
Color Consistency
Grout acts as part of the design with glass tile, so maintaining consistent grout color over time is important. Some cement-based grouts can fade or discolor. Use a grout known for color consistency.
Ease of Application
Grout with a smooth, creamy consistency is easier to work with for filling narrow glass tile joints. Some epoxy and urethane grouts go on easily. Avoid gritty, stiff grouts.
Best Grout Options for Glass Tile Backsplash
Taking all of the above factors into account, here are the top recommended grout choices:
Epoxy Grout
Epoxy grout is the top choice of many installers for glass tile backsplashes. It offers excellent flexibility, stain resistance, and color consistency. Epoxy grouts resist shrinking or cracking. They are more expensive than other grout types but provide the most durable, low-maintenance option for glass tile. Mapei Flexcolor CQ and Laticrete SpectraLOCK PRO Grout are two popular epoxy options.
Urethane Grout
Urethane grout is another excellent choice for glass tile backsplashes. It shares many of the same benefits as epoxy grout, with maximum stain protection, flexibility, and color consistency. Bostik EzPoxy and Custom Building Products Prism SureColor Grout are two examples of quality urethane grouts for glass tile. Urethane grouts are easier to install than epoxy formulas.
Polymer-Modified Sanded Grout
For a more budget-friendly option, consider a polymer-modified sanded grout. The polymer additive boosts flexibility and adhesion compared to standard cement grout. Polymer-modified sanded grouts provide good stain resistance. Mapei’s Ultracolor Plus FA or Laticrete’s PermaColor Grout are recommended products. Match the joint width with the correct grout sand grade.
Non-Sanded Grout
For glass tile with narrow grout joints 1/8 inch or less, a non-sanded grout is a good choice. Non-sanded grouts have a smooth texture for easy spreading. Use a grout like Mapei Ultracolor Plus or Laticrete PermaColor Grout for best results. Be sure to seal non-sanded grouts properly.
Application Tips for Grout with Glass Tile
Once you select the right grout for your glass tile backsplash, proper application techniques are important:
- Allow the tile thinset to fully cure before grouting, generally 24-48 hours.
- Apply grout with a rubber grout float, pressing firmly into joints. Remove excess grout held on the tile face with a damp sponge.
- Clean any remaining grout haze once dry using a soft cloth or pH neutral cleaner.
- For epoxy or urethane grout, precisely follow the manufacturer’s specific application and cure times.
- Completely seal cement-based grouts after installation according to directions.
- Avoid wiping or disturbing the grout joints during the curing phase.
Choosing the optimal grout for a glass tile backsplash, and applying it correctly, ensures your installation stays beautiful for the long haul. With the right grout choice, your glass tile design will maintain its pristine appearance and lasting durability.
Frequently Asked Questions
Can I use sanded grout with glass tile?
Sanded grout can be used with some glass tiles, but only if the joints are wider than 1/8 inch. The sand particles in sanded grout help fill wider joints, but can scratch glass tile if forced into narrower spaces. Use non-sanded grout for glass tiles with joints less than 1/8 inch.
How soon can I get the grout wet after applying?
It’s best to allow the grout to cure for 24-48 hours before exposing it to water. Check the manufacturer’s recommendations, as some epoxy and urethane grouts may require 3 days or longer before getting wet. Taking a shower too soon can weaken the grout bonds.
Should I seal the grout on a glass tile backsplash?
Sealing is strongly recommended for cement-based grouts, including sanded, non-sanded, and polymer-modified types. Epoxy and urethane grouts typically don’t require sealing. But sealing gives an added layer of protection for any grout on a backsplash. Use a penetrating grout sealer.
What’s the easiest grout to work with for glass mosaic tile?
For intricate glass mosaic sheets, the easiest grout to work with is a smooth, creamy non-sanded formula. Non-sanded grouts spread easily into the tiny joints between mosaic tiles without scratching. An epoxy or urethane grout is also a good option for mosaics.
Can I clean and polish epoxy grout on a glass tile backsplash?
Yes, it is possible to clean and polish epoxy grout haze to restore the finish. Use a low RPM buffing pad and a mild abrasive polish. Work in small sections to re-polish the epoxy. Avoid acidic cleaners which can damage some epoxy grouts over time.
Conclusion
The grout used with glass tile backsplash installations is noticeable and an important design element. Choosing a grout with the right features ensures your backsplash stays beautiful for the long-term. Epoxy and urethane grout provides top-of-the-line performance, while flexible polymer-modified sanded grout works for those on a budget. Always apply the grout correctly following recommendations. With the proper grout selection and application, glass tile backsplashes can deliver lasting elegance and function.
