Porcelain Refinish Repair questions, answered by experts

You can put hot pans on porcelain countertops. Porcelain is highly resistant to heat—it’s manufactured at around 2,500 degrees Fahrenheit, so it can withstand a ton of heat without cracking or damaging. Even though the high heat is a plus, you should still be cautious when putting hot surfaces on porcelain countertops.

You can put new grout over old grout, but it’s not always the best choice. For example, if your existing grout is cracking due to an underlying issue, regrouting shower tiles on top of old grout is just covering up a bigger issue.

If you’re sure there’s no issue other than cosmetic problems, you can put new grout over old grout. Just use the same type of grout to maximize adherence, and be sure to match the color for the best look.

You can take a sample of your existing grout to your local hardware store and ask them to match the color. For the most accurate results, choose a sample that hasn’t been discolored from wear and tear. You can also try to clean the floor tile grout to get it closer to its original color.

Minor repairs, like grout touch-ups, can be done DIY, but professional service is recommended for significant repairs or replacements to maintain tile integrity and aesthetics.

Although it may be challenging to assess damage behind your tiles visually, be on the lookout for these telltale signs that could hint at water damage. Inspect for an accumulation of excessive water near your tub and shower, notice any unpleasant mildew odors, or observe cracks in the grout. If you notice any of these warning signs, it's advisable to contact a local plumbing repair company to evaluate and address the issue promptly.
