I'm in the process of restaining rooftop deck. I first washed it with a deck cleaner product. I'm now in the process of sanding. I was hoping to ask a few questions:
I noticed a few areas where dryrot had set in. I'm hoping these are small enough that they can be repaired with a wood filler or bondo product. They're on the top edge of the 2x4s. The largest measures approximately 14x1 and is maybe a half inch deep (the affected area slopes). Is that possible? Is there any product recommendations?
After sanding the deck, I still noticed some very small areas where algae existed. Is it safe to paint over those or should I wash the deck a second time? Does washing the deck require me to resand? Each time that takes a few days and being in a rainy climate, my window to complete the staining isn't very long.
If there are very small cracks running the length of the wood, should those be filled before applying new stain?
