Can you put this on this stain over it? Does it come clear if you dont tint it?

Thank you for the question. We apologize for the delay in response. You will need to prepare previously stained or weathered surfaces with Cabot Problem-Solver Wood Cleaner, Wood Brightener or Wood Strippers. On severely weathered surfaces, sanding may be required to completely remove all loose wood fibers. This product must be tinted in order to be successful. Sincerely, Alex Cabot Customer Support
