There are many different ways of applying epoxy paint and spraying epoxy paint is one of them. If you have a large enough surface or the surface is too uneven for more conventional methods of application, this guide will assist you along the way.
1. Be sure to have either enough surface area or the correct surface area to spray before you break out the spray equipment. The area should be at least large enough to spray a minimum of 3 gallons of Pond Shield if the surface is smooth. If the surface is too rough such as a very craggy type of surface, then it would also be beneficial to spray rather than brush or roll.
2. Because most spray equipment consists of a pump, hose and gun, some material will be lost during the application process. This material ends up being left behind within these areas of the spray machine at which time it is cleaned out before the machine is put away. It is important to be able to justify this loss of material before you begin. Some machines have enough hose and mechanical parts to cause a loss of up to a half to a full quart of material.
3. Spraying epoxy pain is best accomplished by two people. One person can constantly spray material onto the surface while the other can mix new batches of material having them ready as the person spraying runs out. This team work will keep the risks of epoxy hardening up in the machine to a minimum.
4. Use proper protective gear. When you spray epoxy paint, the coating is atomized into small particles that float in the air. These particles remain in an uncured stated for as long as the coating is not set up. During this time it is possible inhale these particles unless a proper spray mask is worn to prevent it. You should always protect your eyes and lungs when spraying.
5. Epoxy can get onto other surrounding items as well. Use plastic sheeting or tarps to cover any areas exposed to accidental overspray.
6. Be ready to clean the spray machine in the event something goes wrong. Epoxy will cure and if it is still inside the machine will do so there. This can ruin a machine very quickly.
7. Always pre clean the spray machine, especially if the machine has been rented. It is impossible to tell what was used in the machine prior to your use (if rented) and anything left in the machine can easily contaminate the epoxy.
Spraying epoxy paint is no different than spraying any other material except that the curing process of the coating is chemical rather then mechanical in nature from heat, ultraviolet, evaporative or pressure. Because of this, the mixture needs to be tended to more closely which is why a team is always more successful than a single person spraying epoxy paint.
