I've been building a small cabin in the mountains for the past year or so in my spare time and finally have a sub floor laid out and screwed down. I have no time frame as to when I get a roof over the floor and with winter approaching, I'd like to get something to protect my OSB from the elements.
I am in southern california and we're supposed to have a wet winter. Not necessarily snow, but a lot of rain. I know the OSB comes presealed, but I'd like to add another layer of protection.
I was thinking something like deck sealer or this patio paint from HD: http://www.homedepot.com/p/BEHR-Premium-1-Gal-PFC-35-Rich-Brown-Low-Lustre-Porch-and-Patio-Floor-Paint-630001/203939583
I spent $100 dollars on a thick, large tarp that lasted a couple months, but the wind destroyed it. It gets pretty windy up there. Below is a picture of the subfloor I have finished. It is about 320sqft.
I understand, I can't completely waterproof this stuff, but I want to try and at least get it through this winter season.
