Subliner Dry Waterproofing Sheet Membrane

Installation on floors or other suitable, non-waterproof underlayments or substrates.

The wedi products within the group of Subliner Dry Systems offer specific benefits in installations and applications complementing our traditional wedi

Building Panel

and Shower Systems. Subliner Systems are Sheet Membrane products, each designed to provide sound and thin profile underlayments for tile. Each of the system

components provide water- and vapor proofing as needed over common cement or fiber cement backer boards or mortar beds or other comparable and suitable

traditional structures for tiled applications in wet rooms. The wedi

Subliner Dry Sheet Waterproofing Membrane and its Subliner Accessories and components are sealed

and connected with 2” (50.8 mm) wide membrane overlaps. In between, wedi

Sealant 620, a specialty sealant, is used to water- and even vapor proof these connections.

Lay out wedi

Subliner Dry and cut

to size using a knife or scissors.

Apply thinset mortar to the

prepared subfloor using a 1/8 x 1/8”

(3.2 x 3.2 mm) or 1/4 x 1/4” (6.4 x 6.4

mm) notch trowel.

Insert wedi

Subliner Dry with the

printed side facing upward and

press on with a rubber roller or

wooden float. Remove air pockets

and other foreign particles from

below the sheets.

The sheets must overlap 2” (50.8

mm) at joints/transitions. Leave

these overlapping areas free of any

thinset and use tape to keep them

folded upward and/or clean. Once

the thinset has cured, apply wedi

Sealant 620 as a full bed onto the

lower mat’s seam connection area

and press the top overlap flap into

the wedi

Sealant 620.

Spread all the wedi

Sealant 620

flat using a putty knife. Cross joints

should be avoided.

In complete wet rooms, wedi

recommends to flash Subliner Dry

up the wall by 2” (50.8 mm) where it

is still invisible behind the

baseboard tile or wood

applications.

Start setting tile.
