Marine Epoxy

Marine epoxy is needed in the boat building industry. Epoxy is what ensures a boat a gain in reliability, strength and beauty. Marine epoxy has two components: resin and hardener. When mixing the two components one must pay attention to the recommended ratio. Trying to change the ratio in the hope of speeding up the curing process may lead to either a final product that is too flexible either the curing not taking place at all. Bad mixing practices are the source of most problems. A thorough cure involves a certain amount of time of mixing and a certain style: it may be that an aggressive mixing style is needed, swiping the sides and bottom.

Before applying marine epoxy the surface should be cleaned. Any contaminants, like oil, grease, pooled water, must be removed. Light sanding is also useful. The cleaning of the surface should be done with a clean cloth that is moistened with plain water or Isopropyl alcohol, but never with acetone or recycled solvents. The necessary tools when applying marine epoxy depend on the purpose. For coating, plastic squeegee, disposable brushes and a short nap 1/8" nylon bristle roller are needed. For bonding, one will need a glue brush or a squeegee that has notches cut into the edge.

Marine epoxy needs protection from sunlight. Outdoor pieces may be protected by a high quality varnish. Urethane with UVA protective additives and paint are other options.

When working with marine epoxy it is very important to use protection, since improper use of epoxy can lead to serious injuries and health problems. Safety glasses, respirators and gloves should be worn in order to stay safe. All direct skin contact with resin, hardeners and mixed epoxy should be avoided. Do not try to remove epoxy from the skin by using solvents but by using soap and water. Wash well before eating/smoking to avoid ingestion.
