{"product_id":"schluter-kerdi-kereck-inside-corner-90","title":"Schluter® KERDI-KERECK Inside Corner 90°","description":"\u003cp\u003eKERDI-KERECK inside corners are pre-formed, factory-shaped waterproofing pieces that create a watertight seal at every 90° inside corner in your shower or wet area. They're made from the same KERDI membrane material as the sheet goods, but pre-shaped so you don't have to hand-fold KERDI-BAND — which is where most DIY waterproofing mistakes happen.\u003c\/p\u003e\n\n\u003cp\u003eEach piece has two flat flanges that overlap the adjacent KERDI membrane by at least 2\" on each side. Set it in thin-set mortar, embed the flanges, and the corner is permanently sealed.\u003c\/p\u003e\n\n\u003ch4\u003eWhere inside corners occur in a shower\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eWhere two walls meet (vertical corners)\u003c\/li\u003e\n\u003cli\u003eWhere walls meet the floor (horizontal corners)\u003c\/li\u003e\n\u003cli\u003eWhere walls meet the ceiling (steam showers)\u003c\/li\u003e\n\u003cli\u003eWhere the curb meets the wall\u003c\/li\u003e\n\u003cli\u003eWhere benches meet walls\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eWhy pre-formed corners matter\u003c\/h4\u003e\n\u003cp\u003eHand-folding KERDI-BAND into a 90° corner creates wrinkles and air pockets. Air pockets = unbonded areas = potential water pathways. Pre-formed corners eliminate that risk. The factory shape is smooth, wrinkle-free, and makes full contact with the thin-set bed. For the small cost per corner, there's no reason to hand-fold.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eApply thin-set mortar to both surfaces of the corner\u003c\/li\u003e\n\u003cli\u003ePress the KERDI-KERECK into the mortar with flanges fully embedded\u003c\/li\u003e\n\u003cli\u003eSmooth out air pockets — full contact is critical for waterproofing\u003c\/li\u003e\n\u003cli\u003eOverlap adjacent KERDI membrane strips by minimum 2\" over the flanges\u003c\/li\u003e\n\u003cli\u003eSeal any remaining transitions with KERDI-BAND\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eSpecs\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: KERDI waterproofing membrane\u003c\/li\u003e\n\u003cli\u003eAngle: 90° inside corner\u003c\/li\u003e\n\u003cli\u003eFlange overlap: Minimum 2\" on each side\u003c\/li\u003e\n\u003cli\u003eBond: Thin-set mortar (Schluter SET, ALL-SET, FAST-SET)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eHow many do you need?\u003c\/h4\u003e\n\u003cp\u003eCount every inside corner in the shower: typical 3-wall shower has 2 vertical wall-to-wall corners + 3 wall-to-floor corners + 2 curb-to-wall corners = 7 inside corners minimum.
