        "text": "Proper waterproofing happens behind the tile, not on top of it. Grout and tile surfaces are water-resistant, but they are not 100% waterproof. Professional installation requires installing cement backer board or waterproof foam boards over the framing, followed by taping all seams with fiberglass mesh and liquid-applied or sheet waterproofing membranes. All plumbing penetrations and corners receive specialized sealing collars. This ensures that any moisture penetrating the grout joints hits the barrier and drains harmlessly down into the shower pan or tub basin instead of entering the wall cavity.",
