Protective coatings
A protective coating is a thin film that stands between a surface and whatever wants to wear it down: water, chemicals, abrasion, salt or sunlight.
What they are
Protective coatings are liquids that cure into a continuous film. Epoxies, polyurethanes, polyureas and acrylics are the common families. Each one trades off hardness, flexibility, cure speed and how it handles sunlight.
Why surface prep matters most
A coating is only as good as its bond. Most early failures trace back to a surface that was damp, dusty, oily or too smooth. Grinding or blasting, then testing moisture, is usually the biggest part of the job.
Where it is used
- Concrete decks, ramps and walkways
- Steel structures, tanks and pipe
- Secondary containment areas
- Roofs and parapets
Things to check
- Moisture coming up through concrete
- Sunlight on coatings that chalk or yellow outdoors
- Recoat windows between layers
- Ventilation and protective gear during application
