Process and device for quick dry and or rapid set aqueous external coatings

A process for applying a rapid set aqueous coating comprising a liquid resin and a liquid accelerator, the process comprising:

• starting an airless spray mechanism;
• mixing the liquid resin;
• installing an accelerator tip on an accelerator nozzle of a spray gun, the spray gun comprising a resin nozzle, a resin supply line connected to the resin nozzle, the accelerator nozzle, and an accelerator supply line connected to the accelerator nozzle, wherein an angle between the resin nozzle and the accelerator nozzle is adjustable, the liquid resin is liquid and a resin, the liquid accelerator is liquid and an accelerator, the resin supply line is configured to supply the liquid resin to the resin nozzle, the accelerator supply line is configured to supply the liquid accelerator to the accelerator nozzle, and the cospray gun is an airless cospray gun that does not use air to pressurize the liquid resin through the resin supply line and does not use air to pressurize the liquid accelerator through the accelerator supply line;
• adjusting a pressure of the liquid accelerator to between 40 to 100 psi;
• installing a coating tip on the resin nozzle;
• adjusting a pressure of the liquid resin between 500 and 1000 psi;
• and
• aligning nozzle tips of the resin nozzle and the accelerator nozzle such that an accelerator spray intersects a resin spray at an angle between 90-165 degrees to intermingle and mix the liquid resin and the liquid accelerator external to the cospray gun, wherein, after intermingling and mixing of the liquid resin and the liquid accelerator, the liquid accelerator accelerates curing of the liquid resin.
