TL;DR
Wood furring, in the pressure-washing trade, is the fuzzy raised grain left on deck boards and other softwoods when excessive pressure or too narrow a nozzle tears the softer earlywood fibers loose from the surface. The washed wood dries with a gray, whiskered nap that telegraphs through stains and sealers and splinters underfoot.
What it means
Wood furring, in the pressure-washing trade, is the fuzzy raised grain left on deck boards and other softwoods when excessive pressure or too narrow a nozzle tears the softer earlywood fibers loose from the surface. The washed wood dries with a gray, whiskered nap that telegraphs through stains and sealers and splinters underfoot. Light cases buff off with a pad or pole sander once the wood dries; prevention is technique, fan tips of 25 to 40 degrees, pressure near 1000 psi or below on softwoods, and letting detergents do the work the wand should not.
