I purchased my house three years ago with a stained from deck. We are getting ready to sell the housing so I found a can of stain left behind from the previous owner for the deck. I mixed the can really well before I started.
I power washed the deck and let it dry for a coupe days. I stained it yesterday and 2/3 came out fine. They other 1/3 has shiny spots/strips, some of which turned gold, purple and rainbow colors?
Can anyone tell me what happened and how I can fix it?
Your stain has been compromised
It's tough to say how to fix it, because there's no real way of knowing exactly why/how
But if you post up the exact product used, where and how it was stored, and any other info you can think of about it, perhaps we could make some educated guesses and/or suggestions on a fix
