Hi folks, Thanks for reading, Im just after some more advice before I pour my SLC in prep for my LVT polyflor Camaro 5g click. I’ve spent ages screwing down my ply, sanding over so nice and smooth, about to ardex feather all gaps prior to laying SLC. I won’t feather the screw holes as I’ll allow the SLC to cover those. I’ve decided to SLC as there is still slight height variations still so just want it as perfect as I can get it (amateur!) I just wondered if anyone has any advice or product recommendations to prevent the SLC leaking and pouring all around the edge and into other rooms surrounding the pour. It’s 34 sqm and will be alongside various rooms etc. I can’t seem to find much luck in finding any product other than masking tape which I’m worried won’t stick enough. Thanks in advance for any helpful tips/advice
