Applying the mix
To achieve good adhesion, firstly apply a thin coat of QUICSEAL 615 firmly onto the substrate using the straight edge of the trowel followed immediately with the appropriate amount of adhesive to achieve the required thickness. The correct notched trowel size to use will depend on the type and size of the tiles.
For large sized tiles and tiles with lugs and grooves, apply a coat of QUICSEAL 615 to the back of the tiles.
It is not necessary to soak tiles before laying with QUICSEAL 615. However, it is a good practice to dip tiles in water to remove dust on the back of the tiles before laying. Lay the tiles onto the adhesive and ensure that a firm pressure is applied to achieve good contact with the adhesive.
Unfavourable climatic conditions such as strong sunlight, wind and high temperature, etc. and very porous substrates may reduce the open time of the adhesive. Hence, careful checks have to be made to ensure that skinning does not occur on the surface of the adhesive before laying the tiles. If skinning has occurred, rework the adhesive before laying the tiles.
The tiles must be adjusted within 20 minutes after laying. The laid tiles must not be washed or exposed to rain or strong sun for at least 2 hours.
Grouting Tile Joints
Wall and floor tile joints can be grouted 2 hours after laying the tiles.
The approximate quantity of QUICSEAL 615 for bonding:
- small size tiles and mosaics is 2.5 ~ 3 kg/m2;
- normal size tiles is 3 ~ 4 kg/m2;
- large size tiles 5 ~ 6 kg/m2;
- very large tiles and stones 8 ~ 10 kg/m2.
- The coverage is also affected by the condition of the substrate and tile size.
QUICSEAL 615 is supplied in 25 kg sets.
