Solid stain applied and cured- added sealant on top, now have white blotches?

You can never apply a sealer over a deck stain so you will have to remove it by stripping and or sanding. You will probably have to restain after as well.

That stinks! So, what's the purpose of a sealant then if not to seal a stain? The directions on the sealant said it could be applied on top of a stain?

Sealers seal unstained wood, never stained wood. Also, deck stains have water repellent properties as well so no need.

Ok, thank you!
