Will Williams. Just picked up 3 bags, each 3 cu ft of hard wood mulch. Apparently, it was wet, couldn't tell because it's in opaque plastic but each bag weighed 85 lbs! That would be better than a factor of 4 between dry and wet if dry is 20 lbs. Be prepared!

All of it. Wash or sweep down each sheet to remove loose rust. Then scrub it with a nylon-bristled brush, and finally with a metal brush. Once you've removed every last particle of rust, repaint the sheet with a rust-preventing primer (Rustoleum or something similar).Then paint on at least 2 coats of a roofing paint compatible with the primer.Rust is sort of like cancer: if you leave even one tiny iota, it will grow back. Wherever the paint sticks to a tiny little bit of rust instead of to the roof material itself, the water can get in under that little hole in the paint.ater got trapped between the sheets. This resulted in surface rust and some oxidation. The sheets are20 ft long. The damage covers about 15% to 20% of all the surface combined.
