APPLICATION INSTRUCTIONS
For the application of SikaBond®-T53 all standard construction guidelines apply.
For further information, please refer to the Method Statement "Full Surface Bonding".
SUBSTRATE PREPARATION
- The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Paint, cement laitance and other poorly adhering contaminants must be removed.
- Concrete and/or cement screeds must be ground and thoroughly cleaned with an industrial vacuum.
- Anhydrite screeds, including flowable anhydrite screeds must be ground and thoroughly cleaned with an industrial vacuum shortly before bonding with the adhesive starts.
- Broadcast mastic asphalt must be primed with Sika® Primer MR Fast, Sika® Primer MB, or Sika® MB EZ Rapid. For the instructions for use, please refer to the corresponding Product Data Sheet.
- Glazed ceramic and old existing ceramic tiles must be degreased and cleaned with Sika® Aktivator-205, or the tile surfaces must be ground and then thoroughly cleaned with an industrial vacuum.
- Wood and/or gypsum boards (e.g. chipboard, plywood) must be glued and/or screwed to the substructure in order to be fixed to the substrate. For floating dry-floors, contact our Technical Service Department.
- For other substrates contact our Technical Service Department for advice and assistance.
- SikaBond®-T53 can be used without priming on cement based floors, anhydrite floors, chipboards, concrete and ceramic tiles.
- For broadcasted mastic asphalt, cement based floors with excessive moisture content and use over old adhesive residues or on weak substrates use Sika® Primer MB. For detailed instructions contact our Technical Service Department.
CLEANING OF TOOLS
Clean all tools and application equipment immediately after use with Sika® Remover-208 and/or Sika® TopClean T. Once cured, residual material can only be removed mechanically.
