Dealing with Sherwin Williams solid color stain
My deck was stained about 2 years ago with Sherwin Wms solid color stain. Not totally sure what was on the deck prior to this (I think it was a semi-transparent or transparent stain). Of course, the new stain is now peeling and it appears (after reading through various other posts) that most strippers won't work on a solid color stain. So - I'm interested in learning:
1). Is there a product that will effectively remove the current solid-color stain?
2). I've already sanded off any loose stain. Is it OK to restain the deck with the same solid color stain?
3). If I restain with the same product, are there any issues if I choose to go with a darker color? The current stain is a light gray. I would go with a darker color.
