Refinishing old wooden (pine) stairs. Sanded out all groves and dents. Used pre-stain. Applied one coat of stain. When it was fully dry didn’t like the color. Purchased same brand stain in darker shade. Did wipe excess off but left it a little heavier trying to achieve the darker tone. I used a dry natural brush to make everything seem even. 24 hours later… the stain is still tacky – Help!
