Faster Curing Times
The membranes special fleece layers enhance the curing process. It increases tile adhesion by up to 5 times sooner allowing for grouting of the tiles earlier.

Time is Money
The membrane's unique surface also allows for pencil marks and chalk lines to stay permanent during the layout procedure. This is a huge advantage, especially when time is money.

Super Strength - Crack Isolation
Thousands of dimpled concrete pillars isolate the tiles from potential floor base cracks. The membrane's unique hydrating process allows the thinset to maximize the bond within the tile floor assembly.

Indoor or Outdoor Use

Compatible with Heat Mats
The preferred and most common installation of heat mats is directly on the substrate (Under SUPERSEAL Tile Subfloor). However you can also install heat mats on top of SUPERSEAL Tile Subfloor.

Tile Subfloor Roll Sizes

SUPERSEAL Tile Subfloor incorporates special layers of fleece that are heat fused with a high density plastic core. The fleece layers absorb moisture out of thinset unlike plastic surface membranes. This allows you to use the TCNA recommended application of modifed thinset on top of the SUPERSEAL Tile Subfloor. As a result, the thinset cures in a very timely fashion (As seen in the video above).

In addition, when the moisture is drawn out of the thinset and into the fleece, it then hydrates the thinset as needed. This enhances the strength of the thinset during the curing process, just like a concrete slab. The tiles adhesion is excelerated faster and stronger that any competing plastic surface membrane in the market.
