How to Prevent Water Damage to Your Tiles

By Grout Medic Denver Staff | 4-1-2025

April showers call to mind an age-old enemy that has caused untold damage. He goes by H2O, or more commonly, water. We combat this enemy by installing tile in areas we know will deal with wetness. For the most part, it works because tile is a durable and water-resistant choice for kitchens, bathrooms, and other moisture-prone areas. However, without proper maintenance, that sneaky enemy, water, can seep through grout lines, weaken adhesives, and cause damage over time. We at Grout Medic want to give you some essential waterproofing and maintenance tips to keep your tiled surfaces looking their best and prevent costly repairs.

Seal Grout Regularly

Grout is porous and can absorb water if left unprotected. To prevent moisture penetration:

• ✅ Call Grout Medic at least once a year because we use a high-quality grout sealer to create a waterproof barrier.
• ✅ Choose epoxy grout for high-moisture areas, as it is naturally water-resistant.
• ✅ Wipe spills immediately to prevent moisture from seeping into grout lines.

Ensure Proper Tile Installation

Water damage often starts with poorly installed tiles. To avoid issues, call the pros at Grout Medic. But if you want to DIY, remember to:

• ✔ Use waterproof backer boards in bathrooms and showers instead of drywall.
• ✔ Apply a waterproof membrane underneath tiles in wet areas.
• ✔ Make sure tiles are properly spaced and grouted to prevent gaps where water can seep through.

Fix Cracked Tiles and Grout Promptly

Small cracks can allow water to reach the subfloor, leading to mold and damage.

• 🛠 Inspect tiles and grout regularly for any cracks or loose pieces.
• 🛠 Use Grout Medic to replace damaged tiles immediately to prevent moisture buildup.
• 🛠 Use Grout Medic to re-grout areas with missing or crumbling grout to maintain a solid seal.

Maintain Proper Drainage

Standing water can damage tiles and create mold issues. Ensure your space has proper drainage:

• 💧 Use sloped flooring in showers to direct water to the drain.
• 💧 Keep drains clear of hair and debris to prevent backups.
• 💧 Install splash guards or water barriers near sinks and tubs.

Improve Ventilation

Excess humidity can cause mold growth and weaken tile adhesives. Reduce moisture by:

• 🌬 Using exhaust fans in bathrooms and kitchens to remove humidity.
• 🌬 Opening windows or using a dehumidifier in damp areas.
• 🌬 Wiping down wet surfaces after showers or cooking to prevent excess moisture buildup.

Choose Water-Resistant Tile Materials

Not all tiles are created equal when it comes to water resistance. The best choices for wet areas include:

• 🏠 Porcelain tiles – Extremely durable and non-porous.
• 🏠 Ceramic tiles – A cost-effective water-resistant option.
• 🏠 Natural stone tiles – Require sealing but add a luxurious, waterproof finish when maintained properly.
