Back Rolling: The process of using a roller frame and cover to finish roll a
Blush: An oily film left on an epoxy floor after curing. Often caused
by high humidity or temperature deviation substrate and ambient air temperature.
Broadcasting: The process of distributing aggregate (i.e. quartz rock, paint flakes etc.)
Broadcast to Rejection: Aggregate broadcast into a wet matrix until surface does not show wetness of resinous material
Cant: A small radius installed at the transition between walls to floor, wall to wall, ceiling to wall to eliminate 90 transition
Centipoise: The unit of measure for viscosity of liquids.
Compressive Strength: The amount of resistance of a material to fracture under compression.
Cove Base: A radius installed at the transition between wall and floors to create a monolithic (one piece) floor to wall
Cutting In: Trimming around columns, posts, and stairs or around the walls.
Elongation: The process of lengthening due to “stretching”.
EPC: Epoxy Polymer Concrete, a combination of epoxy resin and aggregates.
Film Thickness: The measure thickness of a fluid applied coating. DFT = Dried Film Thickness/WFT=Wet Film Thickness
Fish Eyes: Separation blisters usually caused by a surface contaminant.
HAP’s: Hazardous Air Pollutants.
Keying In: Removing a portion of the concrete substrate to create a durable termination point of fluid applied.
Laitance: Milky white substance on the top of concrete.
LEED: Leadership Energy Environmental Design.
MSDS: Material Safety Data Sheet.
MVTR: Moisture Vapor Transmission Rate.
Neat Coat: One layer of coating applied without any aggregate.
Orange Peel: A texture achieved by using a thicker coating, or a larger nap roller cover.
Out-gassing: The process of concrete releasing air, usually soon after surface prep occurs.
PPE: Personal Protective Equipment (i.e. safely glasses, ear plugs, gloves, etc.)
Pot Life: The amount of time a mixed material will stay fluid.
Preconditioning Material: Allowing materials to reach room (ambient) temperature.
Re-coat Time: The time in between cots where one coat can be applied to the previous coat.
Shear Cup Test: A test performed to determine a coatings ability to adhere to a substrate.
Shot-blasting:Mechanically profiling a substrate using steel shot, propelled against the surface at a high velocity to create a proper surface profile
Surface Profile: The texture of the substrate achieved to insure proper bonding.
Substrate: The surface to which a coating is applied (i.e. concrete, wood, gypsum, etc.)
Tact-Free: The time when a coating cures where imprints cannot be left behind.
Tensile Strength: The maximum stress that a material can withstand without breaking or tearing.
Viscosity: The material property that measures a fluid’s resistance to flowing.
VOC’s: Volatile Organic Compounds.
Working Time: The amount of time that exists before a specific coating starts to “tack up”, becoming more dry and harder to spread
