Product Description:

Superseal preformed waterproofing membrane outside corners are an essential component for creating a fully sealed and watertight tile installation in showers and wet environments. Crafted as a single seamless piece, these corners are specifically designed to protect vulnerable transition areas where walls meet floors, preventing water penetration that can damage both tile surfaces and underlying substrates. Their precision-engineered 90 degree design ensures a perfect fit, eliminating gaps and simplifying the waterproofing process. 

Constructed from high-quality modified polyethylene with a durable 5 mil thickness, these corners provide exceptional flexibility while maintaining strength and resilience. The integrated non-woven polypropylene surface enhances adhesion, allowing the corners to bond securely with thinset mortar and waterproofing membranes. This creates a continuous protective barrier that effectively resists moisture, vapor transmission, and everyday wear in high-humidity environments. 

These outside corners are highly versatile and suitable for a wide range of applications, including bathrooms, shower enclosures, bathtub surrounds, kitchens, basements, and other moisture-prone areas. They are ideal for use in residential homes, apartments, condominiums, and commercial spaces such as offices, restaurants, galleries, and retail environments. Their compatibility with various tile types ensures flexibility in design while maintaining reliable waterproofing performance. 

Installation is straightforward and efficient, making these corners an excellent choice for both professional contractors and DIY enthusiasts. Simply apply thinset mortar to secure the corner in place before integrating it with your waterproofing membrane system. Their lightweight construction and user-friendly design help reduce installation time while delivering consistent and dependable results across every project.

Superseal waterproofing membrane outside corners play a crucial role in building a complete waterproof system that protects against leaks, moisture damage, and structural deterioration. By reinforcing critical joints and transitions, they ensure long-lasting durability and peace of mind. Whether you are completing a new construction project or renovating an existing space, these corners provide a reliable, high-performance solution for achieving professional-grade waterproofing results.
