To safely work on your house, use scaffolding that you can build yourself. Nail a three-foot and a five-foot length of 2 x 4 at right angles. Then, make two three-foot triangles of 3/4-inch plywood, attaching them to the 2 x 4’s with eight-penny nails. A double 2 x 6 will support your scaffold from the ground.
lywood is used in the scaffold- ing and access world every day. Wood plank is used to cover gaps and holes in a platform where piping and other obstructions protrude through the scaffold and chop the deck into a mince- meat sandwich.
