Tile Subfloor Residential Concrete Floor



SUPERSEAL Tile Subfloor is a uniquely designed dimpled crack isolation membrane that separates the floor base from the tile floor finish, preventing moisture and crack transfer.
FACT: Thinset and plastic surfaces do not bond well, if at all. With SUPERSEAL Tile Subfloors ultra aggressive fleece layers, you can ensure that the thinset is permanently and tightly bonded to every square millimetre.

On Concrete – unmodified thinset mortar (ANSI 118.1) or modified thinset (ANSI 118.4 or ANSI 118.11)

What are common mistakes when installing tile flooring?

When installing ceramic tile flooring, there are a few different common mistakes that people make. Some of them are:

  • Poor alignment of the ceramic tile
  • Installing ceramic tile flooring around appliances and toilets instead of under them
  • Not wiping off the excess ceramic tile grout before it hardens
  • Not installing ceramic tile flooring on a level or smooth floor
  • Not allowing concrete to fully cure before installing the ceramic tile
How do you prepare for installing tile or natural stone flooring?

Prepare you floor by removing any previous flooring materials and also move all appliances out of the room. Once that is complete, ensure the floor is level. If it’s not level, apply a leveling compound. In addition, check and mark the heights of your doorways when installing ceramic tile flooring to ensure that the doors will open freely. Once you are past this stage you are ready to start installing your ceramic tile.
