Tilemaster Setaflex Semi-Rapid is:
A flexible adhesive and it is ideal for fixing to substrates with limited movement and/or vibration such as plywood overlay and underfloor heating systems as well as for fixing to solid substrates such as concrete and sand/cement screed.
Tilemaster Setaflex Semi-Rapid is ideal for use in areas subject to prolonged or permanent wet conditions such as wet rooms and swimming pools. Tilemaster Setaflex Semi-Rapid can be used internally and externally and it is unaffected by frost after setting.
COVERAGE: 20kg will cover approximately 5 – 6 m² at 3mm bed application

WORKING WITH TILEMASTER SETAFLEX SEMI-RAPID
Before starting, all substrates must be clean, dry, sound and strong enough to support the weight of the tiles, tile adhesive and grout. Remove all dust, dirt, oil, grease and other contaminants that may affect adhesion.
MIXING & APPLICATION:
Always mix powder to water and mix to a smooth, lump free consistency. As a guide for powder to water ratio, 20kg of powder requires approximately 4.4 – 4.6 litres of water. Never add water after initial mixing, as this will impair the strength of the adhesive. Product that has started to set must be discarded.
Key the adhesive into the substrate and trowel out to the required adhesive bed thickness using a notched trowel. Within the open time of the adhesive, bed in the tiles ensuring that there is full, solid bed coverage under the tiles. Regular checks should be carried out to ensure that there are no hollow pockets or voids beneath the tile.
Back buttering tiles will help achieve solid bed fixing and will significantly increase the bond strength.
Clean surplus adhesive from the tiles and joints as soon as possible, as set adhesive will prove very difficult to remove later. Clean tools immediately after use with clean water.
Do not start grouting until the adhesive has set. This time can vary depending on temperature and site conditions. Impervious surfaces may extend the set time. In ideal conditions grouting can begin after 6 hours. If you are tiling an area with limited movement/vibration then you must use a flexible grout such as Tilemaster Grout 3000.
