Waterproof coating system and method of application

1. A spraying system comprising a mixed coating, the mixed coating having a resin solution and an accelerator solution, the system further comprising:

a. a spray gun comprising a first and a second nozzle;

b. a first pump fluidly connected between the first nozzle and a resin solution reservoir;

c. a first delivery tube fluidly connected between the first pump and the first nozzle, the first delivery tube comprising resin solution at a first fluid pressure of below 400 psi;

d. a second pump fluidly connected between the second nozzle and an accelerator solution;

e. a second delivery tube fluidly connected between the second pump and the second nozzle, the second delivery tube comprising accelerator solution at a second fluid pressure;

f. an adjustable valve coupled to an integrator valve assembly and operable to control the flow of accelerator solution;

g. a double-acting valve fluidly connected between said first nozzle and said resin solution reservoir and between said second nozzle and said accelerator solution reservoir;

h. an adjustable valve operable to control the flow of the resin solution into the spray Run; and

i. a trigger operatively connected to said double-acting valve and comprising a safety latch movable to a position to lock the said trigger in closed position; wherein said resin solution comprises a solution of neoprene latex and liquid asphalt emulsion and wherein said accelerator solution includes one of:

a. an aqueous solution of zinc sulfate and water; and

b. citric acid.

2. A spraying system according to claim 1 , wherein the first fluid pressure is greater than the second fluid pressure.

3. A spraying system according to claim 1 , wherein the spray gun further includes an integrator valve assembly fluidly connected to the second nozzle and a compressed air source for combining the accelerator solution with compressed air before discharging the accelerator solution out of the second nozzle.

4. A spraying system according to claim 2 , wherein the first and second pumps are powered by the compressed air source.

5. A spraying system according to claim 1 , wherein at least one of the nozzles is angled toward the other nozzle so that the resin solution and accelerator solution are atomized and combined at a predetermined distance from the nozzles upon discharge therefrom.

6. A spraying system according to claim 3 , wherein the first and second nozzles are angled toward each other.

7. A spraying system according to claim 1 , wherein at least one of the nozzles is angled toward the other nozzle so that the resin solution and accelerator solution are combined at a predetermined distance from the nozzles upon discharge therefrom.

8. A spraying system according to claim 1 , wherein the resin solution has a high pH value and the accelerator solution has a low pH value so that the resin solution immediately coagulates when combined with the accelerator solution.

9. A spraying system according to claim 1 wherein the weight ratio of liquid latex to asphalt emulsion is 1:1.

10. A spraying system according to claim 9 wherein the viscosity of the resin solution is in the range of about 30 to 50 centipoises.

11. A spraying system according to claim 1 wherein the resin solution has a high pH value and the accelerator solution has a low pH value so that the resin solution immediately coagulates when combined with the accelerator solution.

12. A spraying system according to claim 2 wherein the weight ratio of liquid latex to asphalt emulsion is 1:1.
