Can I apply microcement on Sika waterproofing?

For a specific brand of waterproofing, it is sensible to verify compatibility on a small area. When it comes to standard polymer-cement waterproofing with a suitable surface, application is usually possible. Microcement reflects the quality of the substrate. If the substrate is weak, mobile or contaminated, problems typically appear only after completion. It is possible to apply it on single-component and two-component polymer-cement waterproofings; non-absorbent surfaces do not necessarily require priming, or alternatively, apply Primer Plus as a primer.
