parge

/pɑː(ɹ)d͡ʒ/

Etymology

Probably from parget (verb) (perhaps influenced by sparge (verb)), from Old French porjeter, progeter, pourgeter (“to cast; to plaster a wall”) (compare Old French parjeter (“to cast (especially light) widely”); Middle French pourgetter (Lille and Tournai), Norman porjeter (“to plaster”); French pordjèter (“to add mortar between stones”) (Liège and Namur)), from Old French por- (“through”) + jeter (“to throw”), from Latin porrō (“further; onwards”) + Vulgar Latin, Late Latin iectāre, from Latin iactāre (“to cast, hurl, throw; to scatter, toss”) (compare Latin parjactare, purjettare, pargettare, progettare). The noun form of parge was derived from the verb.

noun

  1. A coat of cement mortar on the face of rough masonry, the earth side of foundation and basement walls.“I watch as the mason at the Gilbert house picks up a glob of parge coat on his trowel. He smooths it on, moving from the bottom of the wall to the top. Next, he drapes a white fiberglass mesh from the top of the wall to the bottom and pushes it into the parge coat with his trowel.”

verb

  1. To apply a parge on to a surface.“If your smoke chamber [of a fireplace] is very oddly shaped or virtually impossible to parge, you can solve this problem using expanded metal lath.
