How do I prepare the wood surface?
Scrape away loose paint/stain with a scraper. Sand if necessary. Remove any decayed or damaged wood. Remove any grease, oil, dirt or other debris from area to be repaired. If necessary drill additional 3/8” or 1/2” holes a couple of inches from area to be repaired to apply additional Rhino-Pre Treat product. Ensure area is dry and clean before actual repair (at least 24 hours).
