My deck is 2nd story and 90 feet long with varying widths. I replaced the CCA with Cedar 2 years ago. I solid stained it after waiting 6 months for the wood to dry and cure. The stain peeld wherever there is grain in the wood. The knots held the stain. It only happened on the horizontal surfaces. I sanded the boards by hand and reapplied stain and it peeled where the grain in the wood is again. After sanding could I prepare the cedar with a Solid Cedar stain to prevent peeling. My stain is flesh colored to match the trim on the house and the ballisters look good just the deck is plain cedar awaiting a color that will adhere and match. This is an ongoing problem and short of having a deck fire I am at a loss. I sanded because the chemicals that "treat" wood are too harsh and would cause damage to the lower windows walla and flower beds and lawn below. The sanding was suggested as to remove the milling film that did not come off in power washing.HELP!
