Hand Float – A smaller handheld version of the bull float, ranging in length from 12 to 18 inches. Especially useful for floating along the perimeter of forms or to work in tight spots.
Hard-Troweled Finish – Surface finish obtained by using a trowel with a steel blade for final finishing of concrete. Often used where a smooth, hard, flat surface is desired.
High-Build Coating – A protective or decorative coating that produces a thick film (usually greater than 10 mils) in a single coat.
High-Pressure Water Blasting – A process for cleaning or roughening concrete surfaces using a stream of water delivered at high pressure.
High-Volume Low-Pressure (HVLP) Sprayer – A spraying device that applies high-solids paints and coatings at low pressure and low velocity, to reduce overspray.
Hopper Gun – A gravity-fed system for spray application of coatings or toppings. The material is placed in a hopper attached to a spray gun, which is powered by an air compressor. Often used to apply spray-down systems.
Hover Trowel – A patented lightweight power trowel developed specifically for precision finishing of epoxy, polymer modified, and cementitious overlay systems.
Hydration – The chemical reaction between cement and water that causes concrete or other cement-based materials to harden.
