Quick Tyvek question - leaving tomorrow

[Grimace]

I just picked up a sheet of Tyvek to use as a ground sheet at a construction site. I noticed that the two sides of the fabric are different. One is printed on and it is a bit glossy. The other side has threads visible.

My question. What side is face up when using as a ground cloth?

I'm heading to Montana tomorrow and realized I don't have a clue. Thanks in advance for the quick response.

I could be wrong, but I don't think it matters what side you use. I've never had any issues after years of use. I'd also recommend you wash it to soften it up some.

The slick side goes down. Less duff sticks to the slick side. In theory, the slick side is the side without the printing. After a couple of washings both sides look about the same.
