Sikaceram 240 Flexible Rapid Set Application Instructions:

Plasterboard:

• Porous substrates like plasterboard must be primed with SikaBond PVA+.
  

Concrete Screeds Renders:

• Allow fresh concrete etc to dry for at least 4 weeks before tiling.
• Prime surfaces with SikaBond PVA+ diluted 3 parts water to 1 part PVA Bond and allow to dry.
  

Timber Floors floorboards:

• Suitable for interior floors only.
• Ensure adequate ventilation beneath floors.
• Cover with boarding plywood or chipboard which must be at least 12mm thick preferably 18mm and be of moisture resistant grade.
• Secure with wood screws, not nails, at 150mm centres.
• Prime with SikaBond SBR+ at 1:3 dilution rate.
• Adhesive must be mixed with SikaBond SBR+ diluted 1:1 with water
  

Softwood tongue and groove boarding:

• Boards must be screwed down to joists at 300mm centres and surfaces sealed with SikaBond SBR+ at 1:3 dilution.
• Adhesive must be mixed with neat SikaBond SBR+ to ensure long term flexibility.
• Note: this will slightly retard the set.
  

Existing tiling:

• Ensure tiles are securely bonded to wall.
• Roughen surface of glazed tiles with sander.
• Non porous substrates such as ceramics, should be primed using a slurry coat made of 1 part SikaCeram 240 Flexible Rapid and 2 part Sika Bond PVA+ or Everbuild 505 plasterers gripcoat.
• Mix adhesive with SikaBond SBR+ diluted 1:1 with water.
• Apply adhesive whilst bonding coat is still tacky.
  

Mixing:

• SikaCeram 240 Rapid Set should be added to clean water in a mixing bucket and mixed with a paddle mixer if available.
• The sides of the bucket can be brought into the mix by using a bucket trowel to prevent any dry lumps in the mixed tile adhesive.
  
• Mix approximately 4 parts by volume powder to 1 part by volume water approximately which is approximately 7 to 1 by weight and mix to a slump free mortar.
• Always add powder to water.
  

Application:

1. Using a large notched trowel spread the adhesive evenly onto the substrate the Size of notches depends on size of tiles being used, the surface being tiled, the profile on back of the tiles, and degree of coverage required.
2. Work in an area no greater than 1 meter square or equivalent to 20 minutes working time.
3. Press the tiles firmly into place using a slight twisting action.
4. Tile positions can be adjusted up to 20 minutes after initial fixing.
5. Leave a grout joint of at least 2mm this can be done using tile spacers unless self spacing tiles are used.
6. Surface adhesive should be cleaned from the faces of the tiles with a moist cloth.
7. Rake out excessive adhesive from within joints before setting takes place.
8. The open time of the exposed adhesive bed is approximately 30 to 45 minutes depending on surface porosity and site conditions.
9. Initial set will occur between 1-2 hours.
10. This product will fully harden in approximately 24 hours.
11. It is important the tiles are left undisturbed for a minimum of 2 hours after fixing at normal room temperatures.
12. Do not use at temperatures below +4 deg C.
