Consumption
SikaBond® T-8 is applied in two layers. The first layer is for waterproofing, the second layer for bonding.
Waterproofing layer:
- 2.0−2.7 kg/m2 approx. with metal trowel, in a layer about 2 mm thick
Bonding layer:
- 1.5 kg/m2 approx. with a notched trowel (notches min. 4x4 mm / min. trowel C1)
For substrates primed with Sika® Primer MB, the consumption of SikaBond® T-8 may be reduced.
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 or Sika® Primer MB. For the instructions for use, please refer to the corresponding Product Data Sheet for Sika® Primer MB.
- 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.
- For other substrates contact Sika Technical Service for advice and assistance.
- SikaBond® T-8 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 Sika Technical Service.
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.
