Why Waterproofing Matters

Water and ice can wreak havoc on your stone veneer, leading to issues such as:

  • Structural Damage: Water can penetrate the substrate and cause deterioration over time.
  • Aesthetics: Moisture can lead to discoloration, mold, and mildew, compromising the beauty of your stone.
  • Reduced Lifespan: Without proper waterproofing, your stone veneer may not last as long as it should.

Key Steps to Waterproofing Your Stone Veneer

  1. Prepare the Surface: Ensure the surface is clean, dry, and free of any contaminants.
  2. Apply the Waterproofing Membrane: Follow the manufacturer’s instructions for the specific product you’re using. In the case of Laticrete’s Air & Water Barrier MVIS, you’ll typically apply it with a roller or brush.
  3. Cure Time: Allow the membrane to cure completely before proceeding to the next step.
  4. Install the Stone Veneer: Once the membrane is cured, you can begin installing your stone veneer.
