I recently stained my deck with Olympic Semi-Transparent stain, and applied too much in several areas. These areas are not drying, staying shiny and a bit sticky. Any suggestions on how to remedy this situation?
You should be able to apply some mineral spirits to the glossy areas to soften the gummy residue, then use a scraper and rag to remove excess before it dries. The mineral spirits will not harm the wood or stain, and should re-activate the solids so you can even out the finish. Even if you do nothing, eventually the shiny areas will harden on their own and weather to a uniform color and finish.
