Frequently Asked Questions About Waterstop Streamline – 90° Corner
Q: Can I install the 90° model over an existing screed?
A: No. It must be installed prior to screeding, as it acts as both a fall guide and a barrier. Install it first, then screed to the integrated tile gauge.
Q: Is the 90° angle pre-joined or do I join two straight pieces?
A: The 90° models are supplied as a single, preformed corner profile with two legs – no mitring required onsite.
Q: What if my shower isn’t perfectly square?
A: You can trim either leg onsite using a hacksaw or drop saw to match your actual dimensions. Ensure a tight wall fit for membrane sealing.
Q: Can this be used with frameless glass?
A: Yes. Frameless screens can be sealed directly to the bullnose lip using silicone, creating a seamless connection with the membrane below.
