Cover Guard floor protection recently came ashore from the marine industry, where it has long been used to protect vessel decks and other surfaces during repair and retrofit work. It’s flame retardant and impermeable to water, and its diamond-plate-pattern surface is slip-resistant. It comes in 3-foot– and 6-foot–wide rolls, in thicknesses ranging from 10 mil to 40 mil. Cost is $85 for a 100-square-foot roll, 10 mil thick. Rolls are reusable. Bainbridge International, 800.442.5684, coverguard.com
