Naturally, from weather exposure timber decks and polished concrete floors lose their protective layer. So to keep your outdoor areas looking fresh we recommend a re-coat every couple of years. This first deck had deteriorated in the sun. Its previous owner had stained the deck with the incorrect stain and was not applied properly. Firstly we washed the deck with Intergrain Power Prep to remove the previous coats of stain. Then sanded the deck back to smooth timber, followed by Intergrain Reviva Wash. Waited until dry, then two coats of stain.
