Application

Preparing the Application Areas:

Thoroughly clean the laying area and ensure that after application the same area can be hermetically sealed to prevent infiltration of dust from the outside.

Any possible deposition of volatile dust on the MAT 20 surface, after the application and during the cross-linking period (until touch dry) will cause surface defects highlighted by low thickness and opacity.

Product Instructions for Use:

MAT 20 is ready for use: Shake the container before opening the package.

Always close and immediately the opened container after each use.

On a New Resin Floor:

  1. remove the dust using an antistatic cloth slightly dampened with water / isopropyl alcohol = 1/1;
  2. pour 20 MAT onto the resin surface;
  3. apply with a 25 cm NP Roller model B67evenly and in accordance with the following indicated coverage rate.

On old floors:

  1. clean with STRIPPER diluted 5 times with clean water (with special emphasis in the case of existing WAX-BASED treatments), rinse and remove all excess water, ensuring that no standing water is left behind in the area to be treated. After treatment, make sure the surface is thoroughly clean. If not, repeat the treatment;
  2. Particular attention should be given while removing wax treatments that should be treated with STRIPPER or STRIPPER PLUS according to the instructions given in the related technical data sheets.
  3. After the substrate has perfectly dried, remove the dust using an antistatic cloth slightly dampened with a mixture of water / isopropyl alcohol = 1/1;
  4. 20 pour MAT onto the resin surface;
  5. apply with a 25 cm NP ROLLER model B67 evenly and in accordance with the underwritten coverage rate.
