/diy/ - Do It Yourself

I have first generation Trex decking that is flaking and needs to get replaced. I have a decent sized deck in the back and a wraparound deck in the front and a staircase. Haven't measured it exactly, but probably 400-500 square feet total. The structure is in good shape so I just need to pull the old boards and replace them. How hard is Trex to work with? The old boards are just screwed in, no hidden clips or anything. I've done interior trim work, so I know my way around a miter saw.
