Resinous System Selection
There are overlaps in recommended system applications; however, select types of chemistries are generally used for specific environments. Whether the system selection is dependent on exposure to harmful liquids or excessive abrasion due to wear, the ultimate abuse the surface will experience must be understood to ensure a successful installation.
The selection process begins after a thorough new assessment is done and a full evaluation checklist is created of the potential abusive agents (extreme chemical exposure, light-to-heavy duty wear, wheeled traffic from rubber and / or steel wheel, floors exposed to extreme temperatures or thermal cycling that can cause thermal shock. There may be several types of polymeric industrial flooring systems available to match the job.
In general, system thickness, installation time, chemical resistance, cost, thermal shock resistance, and life expectancy increase as one moves from coatings, to slurries, to broadcast systems, to trowel applied floors. Each of these installation methods use a variety of chemistries. The properties that the chemistry controls are chemical resistance, adhesion, mechanical properties such as tensile and compressive strength, weather-ability, shrinkage, and speed of cure.
Sealers - are generally classified and any concrete coating product that is less than 3 mils in thickness and designed to inhibit absorption of liquids into the concrete. Hardeners are classified as a product that penetrates into the concrete to create a more watertight surface and/or to strengthen the concrete. Acrylic sealers are the most common type of sealer. They are very economical and easy to install. These are often used as a curing compound. (See curing compounds) more info on sealers
