How to Dry Out Water under Tiles: Quick & Effective Tips


Signs Of Water Damage Under Tiles

Water damage under tiles can lead to a range of issues if not addressed promptly. It’s important to be able to identify the signs of water damage so that you can take appropriate action to prevent further damage to your flooring and subfloor. Here are some common signs to look out for:

Discoloration Or Staining

One of the most noticeable signs of water damage under tiles is the presence of discoloration or staining on the surface of the tiles. This could manifest as dark spots or patches that indicate the presence of moisture underneath the tiles.

Loose Tiles

Another indicator of water damage is the presence of loose tiles. When water seeps beneath the tiles, it can weaken the adhesive, causing the tiles to become loose or detached from the subfloor. If you notice tiles that are no longer firmly in place, it could be a sign of underlying water damage.

Tenting Tiles

Tenting, also known as “tenting” or “popping,” occurs when the tiles start to lift or bulge upwards at the corners or edges. This is often caused by the expansion of the subfloor due to water absorption, leading to the tiles being pushed upwards. If you observe tenting tiles, it’s a clear indication of water damage beneath the surface.

Immediate Actions To Take

To dry out water under tiles, start by removing any furniture and using a wet/dry vacuum to eliminate excess water. Place fans and dehumidifiers in the room to circulate air and absorb moisture. Additionally, a heat gun can be used to dry out any remaining moisture in the grout lines.

Immediate Actions to Take:

If you have water under your tiles, it’s important to take immediate action to prevent further damage. Here are some steps you can take right away:

  2. Set the heat gun to a low or medium setting to avoid damaging the tiles.
  3. Hold the heat gun about 6 to 8 inches away from the tile surface.
  4. Moving the heat gun in a slow and steady motion, direct the hot air towards the affected area.
  5. Continue this process until the moisture is completely evaporated.

Remember to exercise caution when using a heat gun and always follow the manufacturer’s instructions for safe operation.

Air Conditioning As A Dehumidifier

If you don’t have access to a dehumidifier, you can utilize your air conditioning system to act as a makeshift dehumidifier. Here’s how to do it:

  1. Ensure that the air conditioning system is functioning properly.
  2. Set the thermostat to a low temperature to maximize dehumidification.
  3. Close all doors and windows in the room to prevent additional moisture from entering.
  4. Allow the air conditioning system to run continuously until the moisture under the tiles is dried out.

Using air conditioning as a dehumidifier can be an effective way to remove excess moisture from the air, aiding in the drying process.

The Role Of Moisture Meters

Moisture meters are invaluable tools when it comes to assessing the moisture content under tiles. These devices measure the level of moisture present in the materials, helping you determine the extent of the water damage and the progress of the drying process. Here are some key points to remember:

  • Use a pin-type moisture meter to measure the moisture content in the subfloor and the tile adhesive.
  • Insert the pins into the materials and read the moisture level on the meter’s display.
  • Regularly monitor the moisture levels to track the progress of drying and ensure complete moisture removal.

By utilizing moisture meters, you can accurately assess the moisture levels and make informed decisions regarding the drying techniques to be employed.

Inspecting And Repairing The Subfloor

When water gets under your tiles, it can lead to damage not only on the surface but also on the subfloor. Inspecting and repairing the subfloor is an essential step in drying out water under tiles. By thoroughly examining the subfloor, you can identify any potential issues and take the necessary steps to repair them.
