The DITRA-PS sheet is a single 3'2-3/4" × 2'5" piece of Schluter's peel-and-stick uncoupling membrane — same technology as the rolls, just sized for fill work. Use it to patch gaps at the edges of a room, fill in around obstacles, or cover small areas like a laundry room or entryway that don't justify a full roll.

At 7.75 sq ft, it's roughly the size of a bathtub footprint. Most installers grab a few sheets alongside their main roll to avoid cutting and wasting roll material on small sections.

When to use sheets vs. rolls

• Sheets: Fill pieces, small rooms, closets, edges, around toilets and vanities
• Rolls: Main floor coverage — fewer seams, faster for large areas
• Pro move: Order your rolls for the main area, then add 2–4 sheets for corners and fill

Same technology, same rules

DITRA-PS sheets have the same pressure-sensitive adhesive, same polyethylene structure, same four functions as the rolls. Installation is identical: peel the liner, press onto a clean substrate, roll flat, tile directly over it with mortar.
