A stable caulk or sealant composition containing as principal ingredients styrene-ethylene/butylene-styrene copolymer and Diethyl ether is disclosed. The composition is generally employed in a canister pressurized with a propellant to expel a stream of water-impervious sealant to fill cracks, crevices and gaps to water damage. When desired, the sealant is removable from the application area.

1. A water-impervious, non-permanent sealant composition comprising: about 17 to 28.4 percent by weight styrene-ethylene/butylene-styrene copolymer, about 65.1 to 76.5 percent by weight of one or more solvents, and 2 to 12 percent by weight of a higher boiling point solvent; whereas after applicatio
1. A water-impervious, non-permanent sealant composition comprising: about 17 to 28.4 percent by weight styrene-ethylene/butylene-styrene copolymer, about 65.1 to 76.5 percent by weight of one or more solvents, and 2 to 12 percent by weight of a higher boiling point solvent; whereas after application of the water-impervious, non-permanent sealant to a surface and after curing of the sealant, the water-impervious, non-permanent sealant is removable. 2. The water-impervious sealant composition according to claim 1, wherein the one or more solvents are selected from the group consisting of tetrahydrofuran, hexanes, diethyl ether, and D-limonene. 3. The water-impervious sealant composition according to claim 1, wherein the higher boiling point solvent is petroleum ether. 4. The water-impervious sealant composition according to claim 1, wherein the one or more solvent is Diethyl ether. 5. The water-impervious sealant composition according to claim 1, wherein the sealant is provided in a canister, the canister having a valve for selectively releasing the water-impervious sealant from the canister, a propellant is added to the water-impervious sealant within the canister, the propellant is selected from the group consisting of propane, n-butane, isobutane and dimethyl ether. 6. The water-impervious sealant composition according to claim 4, wherein the propellant is approximately 50% hydrocarbon, 50% dimethyl ether. 7. The water-impervious sealant composition according to claim 5, wherein the propellant is selected from the group consisting of propane and isobutane. 8. The water-impervious sealant composition according to claim 1, wherein the composition is provided in a tube. 9. A water-impervious, non-permanent sealant composition comprising at a weight percent about: 22.7% by weight styrene-ethylene/butylene-styrene copolymer;70.8% by weight of a solvent; and6.5% by weight of a higher boiling point solvent;whereas after application of the water-impervious, non-permanent sealant to a surface and after curing of the sealant, the water-impervious, non-permanent sealant is removable. 10. The water-impervious sealant composition according to claim 9, in a canister containing a propellant. 11. The water-impervious sealant composition according to claim 10, wherein the propellant is approximately 50% hydrocarbon, 50% dimethyl ether. 12. The water-impervious sealant composition according to claim 10, wherein the propellant is propane. 13. The water-impervious sealant composition according to claim 10, wherein the propellant is isobutane. 14. The water-impervious sealant composition according to claim 9, wherein the solvent is Diethyl ether. 15. The water-impervious sealant composition according to claim 9, wherein the higher boiling point solvent is Petroleum ether. 16. A method of making a water-impervious, non-permanent sealant comprising: placing 17 to 28.4 percent by weight styrene-ethylene/butylene-styrene copolymer into a canister;adding 65.1 to 76.5 percent by weight of a first solvent into the canister;adding 2 to 12 percent by weight of a higher boiling point solvent to the canister;the above ingredients filling the canister from 70 percent full up to as high as 95 percent full by volume;adding a propellant to the canister, the propellant comprising 5 percent to 30 percent of the volume of the total fill volume of the canister; andsealing the canister with a means to selectively release the sealant;whereas after application of the water-impervious, non-permanent sealant to a surface and after curing of the sealant, the water-impervious, non-permanent sealant is removable. 17. The method according to claim 16, wherein the propellant is approximately 50% hydrocarbon, 50% dimethyl ether. 18. The method according to claim 16, wherein the propellant is selected from the group consisting of propane, dimethyl ether and isobutane. 19. The method according to claim 16, wherein the first solvent is selected from the group consisting of tetrahydrofuran, hexanes, diethyl ether, and D-limonene. 20. The method according to claim 16, wherein the higher boiling point solvent is petroleum ether.
