Installation of Large Format Porcelain Tiles for Interior Floors and Walls
Description

Ultralite S2 adhesive is specifically formulated tile adhesive for installing large format porcelain tiles with and without mesh-backing for interior applications on internal floors and walls. It is a one-component, high-performance, highly- deformable lightweight cementitious adhesive with an extended open time, which allows for the perfect bonding of the large format porcelain tiles to the substrate.

Ultralite S2 can also be used for the installation of large format porcelain tiles with or without mesh-backing in wet areas such as bathrooms when used in conjunction with Mapei liquid applied waterproofing membranes, such as Mapelastic Aqua-Defence and Mapelastic Smart. When grouting with either Ultracolor Plus or Kerapoxy Easy Design Grout the final installation will provide a durable and aesthetically superior end result for many years.
