The number one reason we are called to our client’s home for a bathroom remodel project is for water damage because the grout in the shower was not maintained properly. Grout manufacturers recommend that you reseal your grout lines every 9 months, however that is rarely done by your average homeowner. Many are people are too busy or the thought of actually resealing the grout does not come to mind often. Some are just too lazy, but resealing your shower does not take more than 30 minutes to an hour and can save you a lot of headache and money by help preventing water damage.
If you are looking at remodeling your shower or tub surround in your bathroom, when it comes to grouting your new tile you might think about utilizing epoxy grout. Because of its stain resistance, hardness, and durability make epoxy grout the best choice for applications such as showers, kitchen counters, backsplashes, floors, and other heavy-traffic areas versus your regular Powdered Portland cement grouts.
