Outside corners are the other place waterproofing goes wrong. Try to wrap a flat membrane around the convex corner of a curb end, a bench front, or a niche return and it bunches, folds over itself, and leaves exactly the kind of pinhole gap water finds. FloFX NoFlo Outside Corners fix it — they're pre-formed to wrap the convex junction cleanly, for a consistent, watertight outside corner every time.
They bond like the rest of the NoFlo system — fleece-backed and thinset-applied with full mortar transfer — so the corner integrates into the continuous membrane. Use them anywhere the waterproofing has to turn an outside corner: curb ends, bench and knee-wall fronts, half-wall returns, and the outside corners of niches.
Pair them with NoFlo banding and the NoFlo membrane, tied into a FloFX bond-flange drain, for a complete waterproofed shower. The 2-pack handles a standard shower; the 10-pack is the contractor quantity.
Pro tip: Set the outside corner first, then lap your banding and membrane over its flanges — corner under, field over — so water always sheds onto a lapped edge, never into one. Work the thinset for full transfer with no voids under the wrap.
