ABSTRACT:
A large tool for scraping flakes, debris, and droppings from drywall board panels installed in construction work, prior to painting. The blade may be about 1.5 m (5 ft.) long. The central handle is held in both hands. The blade is substantially flexible, and bowed or curved so that its end portions contact the wall first. When the blade is pressed against the wall, the resilient bowed blade straightens out so that the entire length of the blade is in close contact with the wall. The handle is provided with a T or cross-handle portion for pushing the blade along the wall surface by one hand and additionally an arched handle portion for the operator's other hand, to straighten out the curve of the bow. Because of its large size and close engagement with the wall, the scraper saves about half of the prior labor time.
