Grab a bigger trowel because it's the one in your hand and you push too much mortar behind the sheet — it squeezes out at the seams, builds up unevenly, and telegraphs through the tile. Go too fine and the fleece never fully keys in. The KERDI-TROWEL removes the debate. Its 1\/8\" x 1\/8\" (3 mm) square notch is the size Schluter specifies for KERDI.\u003c\/p\u003e\n\u003cp\u003eComb the wall or floor with it and you get a thin, even bed — exactly enough thin-set for the KERDI fleece to bond completely, with ridges that collapse into a uniform layer instead of a mortar surplus fighting you at every overlap. The stainless steel blade resists corrosion and wipes clean, and the cushioned ergonomic handle keeps your grip comfortable through a full shower enclosure, which is exactly the kind of job where a bad handle makes itself known by hour three.\u003c\/p\u003e\n\u003cp\u003eWorth stating plainly, because it's the most common mix-up on the truck: this is the \u003cem\u003eKERDI\u003c\/em\u003e trowel.

Pull a corner back on your first sheet to confirm full mortar transfer across the fleece — and keep the notches clean, since dried thin-set quietly changes your coverage.\u003c\/p\u003e","brand":"Schluter","offers":[{"title":"Default Title","offer_id":48410370605301,"sku":"TRL-KER","price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0316\/2731\/3284\/files\/NEW_KERDITROWEL.webp?v=1784055218","url":"https:\/\/www.tileprosource.com\/products\/kerdi-trowel-1-8-x-1-8-square-notch","provider":"Tile ProSource","version":"1.0","type":"link"}
