I bought a house (condo unit) about 2 months ago whose deck has been neglected for too long (many years). I powerwashed the deck, I tried to avoid spike on the wood due to water pressure but sometimes it was difficult to avoid; anyway I minimized such spikes and was aware of it and had my orbital sander ready once done with pressurewashing part ot it.
After having powerwashing it many cracks and grooves that were previously covered with the mold, mildew and dirt were then clear. After doing some research I went with woold filler (elmer's wood filler). But I am not sure if any small groove in the should be filled with wood filler, and if that is the case I would have to fill almost the entire deck with wood filler. I am attaching some pics to better show the problem:
I realized that I may have used excess of wood filler in some parts, but there were lots of small cracks and grooves. Also since the wood filler has a different color than that of the wood wood stain still work, or would I need to paint it.
Thanks for any help.
