Detailed answer

Microcement follows the substrate; larger imperfections need to be levelled beforehand. In practice, it is important to assess the specific substrate, load, and expected appearance. Microcement is a thin system layer, so the quality of preparation and correct procedure are more important than a simple yes/no answer.

Common mistakes

  • application on dusty or loose substrates
  • skipping the inspection for hollow spots and cracks
  • insufficient degreasing and priming
