Ardex GK Hard Wearing Tile Grout is a cement-based grout for floor and wall tiling, available in Grey or Anthracite, in 11kg bags. Ardex GK is ideally suited to high traffic areas such as shopping malls. For internal and external use.
The BS EN 13888 classification for ArdexGK is CG2A, an “improved cementitious grout with additional characteristic of high abrasion resistance”. Ardex GK has rapid setting and hardening properties and is particularly suitable for grouting ceramic tile joints that have to be exposed to foot traffic within a few hours.
Ardex GK is suitable for use with ceramic and natural stone tiles, extruded tiles, brick pavers and floor tiles with ribbed or studded surfaces. Ardex GK can be used for joint widths from 3mm to 20mm and is suitable for internal and external applications.
Ardex GK can be used with E101 Grout Improver Admix to produce a mortar with elastic and water repellent properties as well as improving adhesion (see E101 Technical Datasheet for more information).
For heated subfloors and porcelain tiles, the grout should include ARDEX E 101. Alternatively, FL Rapid Setting Flexible Tile Grout for Wide Joints should be considered. Where chemical spillages or corrosive liquids are likely to be in contact with the tile joints, use either WA Epoxide Adhesive and Grout or EG8 PLUS Epoxide Adhesive and Grout.
This will depend upon the tile size, joint width and depth and the Grout Coverage Figure, which for Ardex GK is 1.8. Use the following to estimate the approximate grout requirements for square or rectangular tiles:-
Stage (all measurements in mm).
1. ADD length and breadth of tile together.
2. MULTIPLY result by joint width.
3. MULTIPLY result by joint depth.
4. MULTIPLY result by Grout Coverage Figure (i.e. for Ardex GK, this is 1.8).
5. DIVIDE result by length of tile.
6. DIVIDE result by breadth of tile.
The result is the material requirement in kg per square metre.
