DR VTNG PRESERVATME DOWN into the libers oI a piece of wood takes more push than a brush can produce. People make buckets, boats and'barrels out of wood because it resists penetration by liqui&. Penetration means the difference between real treated lumberpressure-treated lumber-and. lumber that has only been painted with or dipped in preservative. Decay and termites work tlrough thin {il'"s of poison in a short rirne.

TI//-TS WHY WoLnanized Lumber* is griven the kind of treahent vital to dependably long service lifevacuum-pressure impregnation in heavy steel cylinders. When the Wolman Sdts* preservative is driven deep into the wood, "fiber-fixation" holds it there, preventing leaching and loss oI protection.

WOLIIANIZED LUInIBER has an enviable perlormance record. Anonq typical cases reported in the booklet, "Service Becords for Wolmanized Lumber", are laundry, bakery, paper and textile rnill insfalhtions, bridges, railroad and mine structures.
