How to Reseal Wooden Boats
- 1). Pull the boat out of the water and allow it to completely dry. Scrape off any moss with a standard paint scraper, and clean the inside of the boat completely. Scrape the outer hull to remove dirt, debris and chipping paint. Pressure- wash the inside and outside and allow the boat to completely dry.
- 2). Caulk any cracks or obvious signs where the wood has split using specialized boating caulk, which can be found at most marine stores or online. Allow the caulk to become tack-free, usually in one to three days, before continuing.
- 3). Pour Clear Penetrating Epoxy Sealer (CPES) into a roller tray, or if using a brush, pour it into a bucket.
- 4). Apply CPES with a roller by working upwards along the outside hull while holding the roller in a horizontal attitude. Do not let the roller go dry, so that a heavy coating of CPES will saturate the wood. Brush it on in the same fashion by starting at the bottom of the boat and working upwards. Again, saturate the wood as much as possible for maximum CPES penetration.
- 5). Reseal the inside of the hull by beginning at the bottom of the boat and working upwards in exactly the same way as the CPES was applied to the outside.
- 6). Paint and fill in large holes after the CPES has cured. Curing time is variable due to fluctuations in temperature. If the temperature remains in the mid-80s for several days, curing of the CPES resins will occur withing 48 hours. At 50 degrees, curing will take as long as eight days.
