Trimaco2602 Double Guard Super Tuff 2-Layer Drop Cloth, 4-feet x 10-feet

How thick is this dropcloth?

Can this cloth be cut as it is too big for the area I need it for?

are these plastic backed? I used a hair dye product that stains the rug if a drop hits it. wondering if these will take the dye and not soak thru

Can you put them in a washing machine!
