So you have made the decision to build a boat; it does not really matter of what type, whether it is a kayak or a canoe or another type entirely. You just need to make sure it as light and as durable as you can build, whether it is from a kit, or you are building it from scratch. Making sure you adhere to one very important rule during the build process can make all the difference in the boat building process.
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.
Marine-Tex FlexSet is an additional option which is a great alternative to the G/Flex adhesives. It is really great for boat applications because it helps bond unlike items like copper (needed for stitching) together with PVC. FlexSet may be used either on top or under the waterline and may be also used for the drying of wet surfaces. It attached to many different kinds of surfaces, securing a flexible yet strong bond.
The next step in applying an Epoxy Resin concrete floor coating is to clean the floor with a chemical stripper. This step helps to remove grease, oil and dirt that are stuck on the concrete. A rotary scrubbing machine is used to help remove the oil and grease. Then a heavy-duty shop vacuum is used to suck up the mixture of dirt, grease, oil and stripper. It is important to get all the dirt removed from the cracks in the floor.
There are a lot of epoxy floor paints that can be bought from hardware stores but most of these just have some instructions on how to mix it. That is why before purchasing it, make sure that you know how to do it or much better one should ask for assistance. Another idea is to have it mixed so that you can just apply it on the floor.
Stitch and glue method involves gluing plywood panels together with the help of fiberglass and wood epoxy resin. Stitching helps to hold the panels in place, when the glue is applied and allowed to cure. There are numerous variations in stitch and glue boat building methods, but the basic remain the same.
Next, set the beam and cut it to the size you need. This will give you the rough sawn look. However, if you want a planned look, I will share another idea that has been shared with me: a planner head and motor can be mounted to the front of the sawmill head on a horizontal mill. The four post heads are strong enough to carry the planer head steadily. The planer head can be mounted on a pivot so that it can be lowered at will or locked up out of the way. After sawing the face on the beam, you lower the planer head to the surface of the beam and start the return of the saw head. This will produce a beam with a beautiful surface. Do this on all four sides and you have a top dollarbeam.
Read the instructions, clean out the holes properly with the recommended brush, insert the proper amount of epoxy, and rotate the all thread slowly into the hole as the epoxy starts to ooze out of it. Do not touch or move the bolt for the next 24 hours.
