Abstract
The present invention relates to a waterproofing spraying apparatus for delivering a waterproofing coating to the exterior surface of a basement wall which requires moisture proofing. The spraying apparatus includes a remote controlled airless fluid pressurizing unit, a pair of hoses and a spray gun. The spray gun including a moveable arm which is moveable between an extended position and a deflected position. Attached to the end of the moveable arm is a pair of nozzles for delivering the waterproofing coating from the spray gun. The waterproofing coating comprising two fluids which are mixed external to the spray gun after leaving their respective nozzle.
Claims14
A spraying apparatus for delivering a fluid coating composition onto a surface to form a waterproofing coating, comprising:
- a first pressurizing pump for pressurizing a first component of the coating composition for delivery to the surface;
- a second pressurizing pump for pressurizing a second component of the coating composition for delivery to the surface;
- a hand held spray gun in fluid communication with said first and second pumps for spraying at least one component of the coating composition;
- a first liquid passageway coupled to said spray gun for the passage of said first component from said first pump to said spray gun;
- a second liquid passageway coupled to said spray gun for the passage of said second component from said second pump to said spray gun, said first and second liquid passageways not in fluid communication;
- and
- an actuator located on said spray gun and moveable to a first state and a second state, said first state for allowing the passage of fluid through only one of said passageways, and said second state for allowing the passage of fluid through both of said passageways.
A method for aligning the nozzles of a waterproofing spraying apparatus with portions of a surface to be covered with a waterproofing coating, comprising:
- providing a handheld spraying apparatus with a pivotable arm, the pivotable arm having the nozzles coupled thereto;
- positioning the pivotable arm proximate the surface to be covered with the waterproofing coating;
- and
- contacting the surface with the pivotable arm so as to move the arm from an extended position to a deflected position.
A spray apparatus for delivering components of a waterproofing coating including a coagulant and an emulsion to a surface, comprising:
- a handheld body for grasping and manipulation by a human;
- a mechanical arm coupled to said body, said arm having a fixed portion and a pivotable portion coupled thereto, said pivotable portion pivotable with respect to said fixed portion between an extended position and a deflected position;
- a pair of coagulant discharge nozzles coupled to said pivotable arm for the discharge of coagulant from the spray apparatus;
- an emulsion discharge nozzle coupled to said pivotable arm for the discharge of emulsion therefrom, said emulsion discharge nozzle located centrally between said pair of coagulant discharge nozzles;
- and
- a pair of conduits extending along at least a portion of said arm, said pair of conduits preventing the mixing of the components within the spray apparatus prior to discharge from said nozzles.
The apparatus of claim 19, wherein said pivotable portion being normally resisted from pivoting by friction forces, and wherein said fixed portion being longer than said pivotable portion.
A spray apparatus for delivering components of a waterproofing coating including a coagulant and an emulsion to a surface, comprising:
- a handheld body for grasping and manipulation by a human, said body having a trigger coupled thereto for allowing the release of components from the spray apparatus;
- a mechanical arm coupled to said body, said arm having a fixed portion and a pivotable portion coupled thereto, said pivotable portion pivotable with respect to said fixed portion between an extended position and a deflected position;
- a pair of nozzles coupled to said pivotable arm for the discharge of components from the spray apparatus, one of said pair of nozzles is for the delivery of coagulant and the other of said pair of nozzles is for the delivery of emulsion;
- actuation means for independently controlling the release of each of the components when said trigger is activated to release fluid;
- and
- a pair of conduits extending along at least a portion of said body and said arm, said pair of conduits preventing the mixing of the components within the spray apparatus prior to discharge from said nozzles.
