We layed a new deck about 6 weeks ago and built a pergola over the top that's yet to have a roof put on yet.
We let it weather and recently just put 2 coats of oil on and it's looking great.
We have a bit of a bird problem in that it seems like a target for their umm "business" and I'm constantly out there scrubbing it off.
The problem I have is that we're going overseas for 3 weeks and it will be out in the open the whole time and no doubt upon our return will be a horrible shade of white
Would it harm the deck if we layed down plastic dust sheets over the top of it while we're away? I was mainly worried about maybe the heat and moisture underneath "sweating" the timber?
I just assumed the leaving the birds "business" on there might stain it. It takes a fair bit of elbow grease to scrub it off after just a day drying in the sun.
Any advice for a newbie?
