The Milestones Project Do you think newly manufactured boards are ready to be stained without any prep work? This is what happens when the “Mill glaze” is not sanded off prior to staining…heavy peeling after only 1 year! After completely sanding all the boards and applying 2 coats of high quality stain! Finally, a beautiful finished product! Before: An old and weathered looking fence…. After: A new and beautiful Fence, which enhances the whole backyard look!
