By equipping property owners and facility managers with the right vocabulary, this section aims to demystify critical concepts and reduce the risks associated with improper application.
Essential Terms Explained
Humidity measures the moisture content in the air, typically expressed as relative humidity (RH). If you hear “80% RH,” it means the air contains 80% of the moisture it can hold at that temperature. For effective coating applications, keeping RH at 50% or lower is key to ensuring proper curing.
Dew point is another term to be aware of; it represents the temperature at which air reaches saturation and moisture begins to condense. If the dew point is too close to the current air temperature, it can cause moisture to form on the roof’s surface, undermining adhesion and shortening the coating’s lifespan. Timing your application around the dew point is crucial.
Next up is moisture content in the substrate. This refers to the water already present in the roofing material. High moisture levels can hinder adhesion, leading to blisters or peeling. Measuring substrate moisture beforehand is non-negotiable for a successful application.
Finally, “cure time” is critical—this is the duration required for the coating to fully dry and bond to the surface. High humidity can drag out cure times, delaying project completions and inflating labor costs. Familiarizing yourself with these terms lays the groundwork for successful roofing outcomes.
Industry Jargon Translated
The roofing industry loves its jargon, and it can be dizzying at times. Take “high solid” coatings—these contain less solvent and more solids, making them ideal for high-humidity environments because they cure more quickly and reduce the risk of trapping moisture underneath.
“Vapor permeability” is another buzzword that describes how much moisture can pass through a roofing material. The vapor permeability rating of a coating affects its suitability for specific humidity conditions. A higher rating means better breathability, allowing any trapped moisture to escape and promoting longevity.
Then there’s “flash point,” the temperature at which a coating starts to emit flammable vapors. This is vital to know even in humid conditions, as elevated moisture can change a coating’s flash point and complicate application safety.
Clearly defining these terms minimizes confusion in conversations with contractors and suppliers. When everyone speaks the same lingo, it ensures that all parties are on the same page, which is crucial for staying on schedule and within budget.
