DITRA-PS is the peel-and-stick version of Schluter's DITRA uncoupling membrane — same four core functions (uncoupling, waterproofing, vapor management, load distribution), but the underside comes with a pressure-sensitive adhesive instead of requiring thin-set mortar. Peel, press, roll, tile. The 269 SF roll is the large-format option for bigger rooms, open-concept floors, or multi-room projects where cutting from one continuous roll is faster than aligning multiple smaller pieces.

At 3'2-3/4" wide by 83'4" long, this roll covers a 269 sq ft area — roughly a large living room, two bathrooms, or a good-sized kitchen. One roll, one application, minimal seams.

Why the large roll?

Fewer seams = faster install and fewer potential weak points. On a 250+ sq ft job, the large roll saves time aligning sheets and eliminates most butt joints. The math is simple: one continuous membrane beats twenty individual sheets every time.

Substrate compatibility

• Concrete — clean, cured, and flat
• Plywood (min 5/8" exterior-grade or Advantech)
• OSB — use PRIMER-PS first for reliable adhesion
• Existing vinyl, ceramic tile, terrazzo — direct application
• Gypsum concrete — apply PRIMER-PS first

Installation notes

• Substrate must be clean, dry, and flat — no dust, paint, adhesive residue
• Apply fleece/adhesive side down, roll firmly with DITRA-ROLLER or screed trowel
• Butt sheets tightly — never overlap
• For OSB, gypsum concrete, or vinyl substrates, prime with PRIMER-PS first
• Store between 41–86°F (5–30°C) — PSA is temperature-sensitive
• Keep out of prolonged UV exposure
