Training
-
The substrate must be dry and clean and must be free of excess material, surface contamination, dust, grease and other contaminants;
-
To improve adhesion (tread layer), the substrate must be cleaned by sandblasting or sanding followed by vacuum cleaning.
Application
Apply acrylic primer with a spray gun;
-
Apply a deep penetrating primer with a watering can;
-
Apply a concentrated primer with a soft brush;
- Avoid puddles on the base.
Cleaning
Tools and equipment must be cleaned and washed with water.
Health and Safety
