If your deck has been painted with deck correct can you reapply deck correct over the old deck correct stain ?

Thank you for the question. We apologize for the delay in response. You will need to prepare previously stained/painted 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. Sincerely, Alex Cabot Customer Support
