{"product_id":"schluter-all-set-modified-mortar","title":"Schluter® ALL-SET Modified Mortar","description":"\u003cp\u003eNot all thin-set works with Schluter membranes — use the wrong mortar and you can compromise adhesion, void the warranty on your KERDI or DITRA installation, or both. ALL-SET is Schluter's modified thin-set, engineered specifically for their system and tested to meet warranty requirements.\u003c\/p\u003e\n\n\u003cp\u003eALL-SET is the safe, universal choice. Use it when you're bonding DITRA or DITRA-HEAT to a wood subfloor (plywood or OSB), bonding KERDI to walls, or setting tile over any Schluter membrane. If you're not 100% sure what substrate you're working with, ALL-SET is the mortar to reach for.\u003c\/p\u003e\n\n\u003ch4\u003eWhen to use ALL-SET vs. Schluter SET\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDITRA over plywood or OSB → ALL-SET\u003c\/strong\u003e (modified required for wood)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDITRA over concrete or gypsum → SET\u003c\/strong\u003e (unmodified preferred)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKERDI on walls → ALL-SET\u003c\/strong\u003e (modified preferred for better adhesion)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTile over any Schluter membrane → either works\u003c\/strong\u003e (ALL-SET is safe; SET is traditionally specified)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eNot sure? → ALL-SET\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eKey specs\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eType: Modified thin-set (ANSI A118.4T, A118.11, A118.15)\u003c\/li\u003e\n\u003cli\u003eColors: Grey and white\u003c\/li\u003e\n\u003cli\u003eOpen time: ~30 minutes at 70°F\u003c\/li\u003e\n\u003cli\u003eWalk-on time: 12 hours at 70°F\u003c\/li\u003e\n\u003cli\u003eGrout after: 12 hours\u003c\/li\u003e\n\u003cli\u003eCoverage: ~40–50 sq ft per bag when setting tile over membrane\u003c\/li\u003e\n\u003cli\u003eShelf life: 2 years (unopened, protected from freezing)\u003c\/li\u003e\n\u003cli\u003eLifetime warranty when used correctly with applicable Schluter products\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eWhy the mortar matters\u003c\/h4\u003e\n\u003cp\u003eUnmodified mortars are chemically compatible with DITRA's polyethylene. Modified mortars — like ALL-SET — add polymer binders that improve adhesion on wood and porous substrates. Use the wrong type in the wrong application and you may get a slip plane between the membrane and substrate, or reduced bond strength on a wood floor where movement matters most.\u003c\/p\u003e\n\n\u003ch4\u003ePro tips\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMix to a fluid, creamy consistency for bonding membranes — slightly stiffer for setting tile on top.\u003c\/li\u003e\n\u003cli\u003eFor DITRA, use a 1\/4\" × 1\/4\" square-notched trowel or the Schluter DITRA-TROWEL.
