How this coating category should be evaluated.
Functional coatings are specified to solve a defined problem such as water penetration, weather exposure, heat, fire behavior, sound, chemical contact or a special decorative requirement. The performance target must be matched with the substrate and complete system.
Application challenge
Waterproofing and specialty applications commonly include joints, cracks, penetrations, variable film thickness and changing weather. These conditions require careful detailing and realistic performance criteria.
System approach
A project brief should define the substrate, exposure, movement, water pressure or weather conditions, required standard and application method. Reinforcement, primer, multiple coats or compatible protection layers may be required.
