Application

Application steps

SUBSTRATE PREPARATION

All surfaces must be clean, dry, sound and free from dust, loose particles and friable materials. Paint, laitance and other poorly adhering particles must be removed by grinding. Standard construction rules or the timber manufacturer’s instructions regarding moisture content of concrete, cement screeds or wooden substrates must be observed.

Concrete/cement screed substrate: No preparation is necessary on a dry, dense, wearable substrate. For other substrate conditions, the floor must be grinded and thoroughly cleaned with an industrial vacuum cleaner. (Important: Pre-Trials absolutely necessary)

Other substrates: In case of flowable screeds and other unknown substrates we recommend that you consult your local Sika Technical Representative.

Priming

The moisture content should be measured in accordance with the Floor Coverings Standard, AS1884-1985. A method of testing concrete moisture is given in the appendix of this standard. When the moisture content of the concrete is found to be below 5.5%, the substrate is generally considered suitable for SikaBond®-T55 (J) to be applied without a primer. When the moisture content of the concrete is found to be greater than 5.5%, Sika® Primer MB must be used as a primer before applying SikaBond®-T55 (J). When the moisture content of recently placed concrete is greater than 10%, EpoCem (Sikafloor®-81 EpoCem® or Sikagard®-720 EpoCem®) should be used as a temporary moisture barrier. Sika Primer MB should then be used as a primer coat before applying SikaBond®-T55 (J). When priming with Sika® Primer MB, a continuous visible film of cured epoxy must be observed on the surface. The application rate will depend on the porosity of the substrate. Older slabs indicating high moisture readings should be investigated to identify why the moisture content is high before proceeding.
