Simply put, a point load is a non-uniform load – think the wheels of a cart, or a nail tip sticking out of the bottom of a pallet. All floors have a compressive strength (load per area in pounds per square inch) that the floor can withstand before failing.
A broom finish is a well-known technique for making concrete slip resistant. It’s created by running a broom over the surface of freshly troweled concrete to create a textured finish. As an Applicator Developer, I’m consistently asked if a broom finish is a sufficient slab profile for a resinous flooring system. The answer is always no.
