Application and properties:
- CEKOL Q-7 EXPRESS is a cement-based adhesive (C) with improved technical parameters (2), fast setting (F) with reduced slump (T) and extended open time (E), C2FTE
- It can be used to bond ceramic, stoneware and natural stone tiles to concrete, brick, aerated concrete, expanded concrete, LECA blocks, gypsum boards and blocks, plasterboard panels, seasoned cement and cement-lime plasters and single-layer gypsum plasters
- Fast setting time (about 4 hours) enables quick repair works
- CEKOL Q-7 EXPRESS recommended for quick installation of small and medium sized tiles
- Reduced slump enables tile installation from the top of the wall
Application:
Substrate preparation
The substrate should be clean, dense and free of grease; any emulsion or oil paint residues and loose sand grains should be removed with a spatula or rough brush.
Mortar preparation
The mortar should be prepared by pouring 1 kg of powder to 0.19 – 0.21 l of water (3.8 – 4.2 l of water for a 20 kg bag), and then mixed thoroughly with a slow mixer to a uniform consistency. Wait approx. 3 minutes and mix thoroughly again. Prepare enough adhesive mortar to be used within 30 minutes.
Application
Apply the adhesive to the prepared substrate using a notched trowel. For heated surfaces, turn off the heat before installing the tiles. Turn on at least 7 days after tile installation. When bonding highly absorbent tiles and stoneware tiles outdoors, apply CEKOL Q-7 EXPRESS in a continuous coat both on the substrate and on the underside of the tiles, which will greatly increase adhesion. Provide a waterproofing layer in areas prone to water seepage.
