Stitch and glue boat plans are probably one of the easiest boat blueprint you can use. This works particularly well if you are a novice in the art of building a boat.
If previous varnish, oil or paint is discolored, peeling or chipping it must be removed before applying a new finish. Varnish, Oil and Paint can be removed by sanding with 60-80 grit sandpaper or the use of a Chemical Stripper. Chemical strippers are designed to brake down the previously varnished or oiled coatings. Apply Stripper with a throwaway brush or spray on the surface of the wood. Allow stripper to sit on surface of wood for 5 to 10 minutes before scraping. Test a small area to see if finish is ready for removal. Then scrape off loosened finish by gently working in the direction of wood grain with a scraping tool or synthetic steel wool. Wipe off sludge with a rough cloth and let dry. If small areas of Varnish or Oil are still remaining, lightly sand wood to remove any remaining old finish.
Of course, to protect your boat from weathering conditions, you will want to paint it. You’ll want to use a poison paint below the waterline as a means to prevent marine growth. Above the waterline, you have much more flexibility.
Brush the joint edges with epoxy and put the two pieces of material together. Brush fiberglass tape with epoxy and wrap it around the joint. Once all the joints are dry, it is time to seal the seams of your hull. Then cover the outside seams with duct tape. Cover the inside seams with epoxy resin then fills with epoxy putty. Next, wet fiberglass tape with Resin for Wood and cover all seams. When the seams on the inside already dry, you can now cover them with duct tape. Repeat the sealing process again on the outside seams.
The cross pattern of the layers, makes plywood much stronger than wood and available in larger pieces. Because of the larger sizes, you can make a section of your boat from one piece of plywood, where it would take many pieces of wood to cover the same amount. This will save a lot of time.
Clean the floor completely of any paint and coatings before you begin. Garage floors may be coated in dirt and oils that must be scrubbed clean before you begin. Search for cracks in the floor that you will repair before applying the first coat of wood epoxy. Getting rid of the cracks and defects in the floor will ensure that your coating applies smoothly to it. Repair kits are available that allow you to inject materials into the cracks.
However, epoxies do have their drawbacks. The first of these to mention is that they are hard this therefore means they are brittle. You can mix them with additives that will make them less so, but the problem caused when you do this is that it will also reduce the strength. It’s therefore best to avoid using them on anything that needs to flex altogether, if at all possible.
A couple of things to remember are that you will not be able to drive on the freshly painted surface for a couple of days. Also, try to avoid scraping your snow blower and other power tools on the epoxy coating as much as possible.
