Application

Preparing the Substrate

-         The substrate must be carefully examined to make sure it is a suitable and structurally sound base, especially if the work is to be done on old surfaces with could have discontinuous areas.

-         Choose the treatment according to the existing surface conditions:

  • simple wetting;
  • washing with high pressure water;
  • acid or alkaline washing;
  • sanding;
  • diamond wheel sanding;
  • removal of any plastic covering, etc.

Doing so any possible obstacles to  the perfect anchoring of RASANTE 1200 S will be removed.

-         Any hollow or irregularity measuring more than 5 mm in size must be previously evened out with GROVE RAPIDO.

-         On old concrete, if needed, the anti-dampness cycle shall be carried out before proceeding any further.

-         You must restore old concrete, if necessary, before going any further.

-         Cured surfaces with existing chalking must be impregnated with NORDLATEX VA.
