The spray application system includes (i) an airless spray device that is configured to receive the fluid material and to spray the fluid material onto the surface, and (ii) a receptacle that is attached to the airless spray device and is configured to supply one or more components to the fluid material. The method further includes supplying the fluid material to the airless spray device, supplying one or more components to the fluid material via the receptacle, and spraying the fluid material and the one or more components onto the surface using the airless spray device of the spray application system. The one or more components are capable of triggering curing of the fluid material. This invention further relates to a spray application system. ## Claims ### Claim 1 A method comprising: obtaining a spray application system that is configured to apply a fluid material to a surface, the spray application system comprising: (a) an airless spray device that is configured to receive the fluid material and to spray the fluid material onto the surface, the airless spray device having (i) a handle with a connector that is configured to connect to a pressurized spray fluid source that comprises the fluid material, and (ii) a spray outlet that is configured to spray the fluid material out of the airless spray device, wherein the fluid material comprises an adhesive, and (b) a receptacle that is attached to the airless spray device and is configured to supply one or more components to the fluid material, the receptacle being attached to the airless spray device via a coupling member that is positioned between the spray outlet and the handle of the airless spray device, wherein the one or more components is configured to cure the fluid material, and wherein the one or more components comprises (i) water, (ii) an additive, (iii) a catalyst, (iv) a solvent, or (v) a combination of (i), (ii), (iii), and/or (iv); supplying the fluid material to the airless spray device; supplying the one or more components to the fluid material via the receptacle and the coupling member, while the fluid material is within the airless spray device; spraying the fluid material and the one or more components onto the surface using the airless spray device of the spray application system; and curing the fluid material with the one or more components on the surface, wherein the supplying of the one or more components to the fluid material occurs prior to the spraying of the fluid material and the one or more components onto the surface, and wherein the surface is a roofing surface, a wall surface, a ceiling surface, a floor surface, a below grade surface, a building surface, a container surface, a vehicle surface, or a combination thereof. ### Claim 2 (depends on 1) The method according to claim 1, wherein the supplying of the one or more components to the fluid material is conducted at least one of (i) constantly as the fluid material is being supplied to the airless spray device, or (ii) intermittently as the fluid material is being supplied to the airless spray device. ### Claim 3 (depends on 1) The method according to claim 1, wherein the supplying of the one or more components to the fluid material via the receptacle is conducted through gravity or vacuum feed from the receptacle to the airless spray device. ### Claim 4 (depends on 1) The method according to claim 1, wherein the one or more components decrease the time for the curing of the fluid material. ### Claim 5 (depends on 1) The method according to claim 1, wherein the one or more components are supplied to the fluid material at a ratio of 0.1 to 10 parts component(s) to 90 to 99.9 parts fluid material. ### Claim 6 (depends on 1) The method according to claim 1, wherein the one or more components are supplied to the fluid material at an amount of less than 0.5 percent by weight of the fluid material. ### Claim 7 (depends on 1) The method according to claim 1, wherein the spraying of the fluid material and the one or more components onto the surface is conducted in at least one of (i) an environment having a relative humidity level of from 10% to 50%, or (ii) a closed system with no access to moisture. ### Claim 8 (depends on 1) The method according to claim 1, wherein the handle of the airless spray device is attached to a tubing that is configured to supply the fluid material to the airless spray device. ### Claim 9 (depends on 1) The method according to claim 1, wherein the spray application system is hand-held and portable. ### Claim 10 (depends on 1) The method according to claim 1, wherein the receptacle is attached to the airless spray device via the coupling member at a region having a negative pressure produced by at least one of (i) a reduced diameter or (ii) a high speed liquid flow, which will generate a vacuum and suck the one or more components into the fluid material to thereby mix the one or more components with the fluid material when supplying the one or more components to the fluid material via the receptacle. ### Claim 11 (depends on 1) The method according to claim 1, wherein the one or more components comprises water. ### Claim 12 (depends on 1) The method according to claim 1, wherein the one or more components comprises an additive. ### Claim 13 (depends on 1) The method according to claim 1, wherein the one or more components comprises a catalyst. ### Claim 14 (depends on 1) The method according to claim 1, wherein the one or more components comprises a solvent. ### Claim 15 (depends on 1) The method according to claim 1, wherein the adhesive comprises a moisture-cured adhesive. ### Claim 16 (depends on 1) The method according to claim 1, wherein the one or more components are supplied to the fluid material at a ratio of 10 parts component(s) to 90 parts fluid material. ### Claim 17 (depends on 1) The method according to claim 1, wherein the one or more components are supplied to the fluid material at an amount of 0.01 percent to 10 percent by weight of the fluid material.
