I stained my deck a year ago using a 5 gallon bucket of TWP stain. I already stripped and brightened my deck because the stain got all black and mildewy over the winter even though I live in arid southern California. I still have half of the 5 gallon bucket of TWP left that I have stored in my garage. Is the leftover stain still ok to use? I am still not sure I should anyways due to the early failure of the previous coat, but I am considering my options.
Thanks,
Wade
This depends on how well the top was closed. Does it mix up nicely with no clumps? Make sure it is not "thicker" then it was when last used.
