As a general rule, the required properties of a floor coating cannot be met by a single coat. Typically three or four coats that have been balanced with each other are necessary for a long term performance of the floor coating system. The various coats in a multi-coat system can be designated as follows:
1. PRIMER - its functions are:
- to act as the basis of the multi-coat system
- to provide adhesion between substrate and coating
- to protect the substrate against environmental influences (e.g. corrosion)
- to protect subsequent coats from the substrate (e.g. the alkalinity of concrete): barrier layer
2. BODY COAT - could be one or more coats depending upon the thickness specified and functionality - its functions are:
- to improve the barrier effect of the primer
- to create optimum surface for the topcoat - covering, levelling of substrate roughness, grindability
- to absorb mechanical load
- to build the required thickness
- to optical properties - color, gloss, design, etc.
3. TOPCOAT - its functions are:
- weatherability (e.g. UV radiation, humidity, etc.)
- chemical resistance (e.g. battery acid, chemical spills, etc.)
- resistance to solvents
- impart abrasion resistance to the body coat
- act as wear layer
The individual coats in a multi-coat floor coating system need to be balanced to each other. Multi-coat systems can have an over all thickness of up to 1/4" or sometimes even more.
Duraamen has floor coatings that can be as thin as 5 mils and they can be as thick as 1/4". For floor conditions requiring more than 1/4" thickness, we recommend building the thickness with self-leveling concrete.
