Description  

Waterstop Streamline 135° Corner (2/3 Leg) is a specialized waterproofing barrier designed for neo-angle or diamond-shaped shower layouts in residential and commercial wet area construction.

Constructed from architectural-grade 6463–T5 aluminium, this profile features a factory-sealed 135° junction and an integrated 3mm tile gauge to ensure precise screed falls and a continuous, leak-proof barrier without the need for manual on-site mitring or welding.

This system helps direct membrane application behind the bullnose lip for frameless glass integration and maintains full compliance with AS 3740:2021 standards to prevent sub-tile water migration.

Common Questions  

Frequently Asked Questions About Waterstop Streamline – 135° Corner

Q: What kind of shower layouts use the 135° model?

A: It’s commonly used in neo-angle or diamond-shaped showers where two or more walls meet at a 135° angle with a return screen.

Q: Can this be ordered in custom leg lengths?

A: Yes. Custom leg lengths are available upon request. Just specify your measurements when ordering.

Q: Is the angle flexible?

A: No. The 135° angle is fixed at the factory to ensure perfect waterproofing alignment. Do not attempt to bend or adjust.

Q: Can it be installed on an uneven screed?

A: No. It must be installed before screeding. The profile serves as a height and slope guide during screed application.

How To Apply  

Applying Waterstop Streamline – 135° Corner: Protocols & Best Practices

General Application Steps:
  1. Dry Fit: Position profile to confirm all legs and angle align with your intended layout. Mark pencil lines on substrate.
  2. Surface Prep: Remove dust and debris. Apply continuous urethane sealant within marked guide area.
  3. Place Profile: Lower into position gently. Use level to confirm that each leg sits flat. Wedge if necessary.
  4. Seal Corners: Apply sealant at wall joins and internal gussets. Smooth with spatula to ensure watertight join.
  5. Waterproof: Apply 2 coats of membrane up behind the bullnose lip. Avoid coating the front edge of the lip.
  6. Screed and Tile: Screed flush with tile gauge. Tile flush to both sides of each leg. Remove tape last.
Limitations and Safety Info  

Limitations & Safety

Product limitations and safety information

Limitations:

  • Not adjustable – 135° angle is factory fixed and must not be bent.
  • Only suitable for internal wet areas – not UV or outdoor rated.
  • Must be installed before screeding or tiling begins.

Safety & Handling:

  • PPE: Wear gloves when handling edges. Use eye protection during cutting or sealant application.

Suitable Substrates  

Waterstop Streamline – 135° Corner Adhesion & Preparation Guide

    Substrate preparation guidelines
  • Subfloor Prep: Mark both outer and inner lines of all legs. Clean surface thoroughly. Ensure corner junction is stable.
  • Timber Floors: Apply full membrane layer first. Then fix profile and re-membrane shower area inside Streamline.
  • Concrete Floors: No primer needed. Apply urethane sealant directly to clean slab between guide lines.
  • Angled Configuration: Ensure angle is set before installation. Do not force open or compress the 135° joint.
