Home renovators and contractors, this IB Tools waterproofing membrane is absolutely essential for any wet area project! The 90 square foot roll gives you plenty of coverage for showers, bathrooms, steam rooms, and other moisture-prone areas. At 20 mil thick and 3 feet 3 inches wide, it provides serious protection against water damage for your tile installations. The high polymer polyethylene polypropylene mat with nonwoven polypropylene fabric on both sides creates an effective barrier that prevents water vapor from spreading to adjacent rooms. It has a low permeability rating that makes it perfect for steam rooms and showers where vapor protection is crucial. Installation involves using uncoupling membrane mortar (thin-set adhesive), and once it cures, you can apply ceramic, porcelain, stone, glass, or pretty much any type of tile directly on top. This membrane works for both new construction and renovations, making it versatile for various projects. It's approved for residential and commercial use, so you know it meets professional standards. Whether you're tackling a DIY bathroom remodel or working on commercial spaces like restaurants or malls, this waterproofing membrane delivers reliable protection that ensures your tile work lasts for years without water-related issues. It's one of those building materials that's worth investing in for long-term peace of mind.
