Abstract

The present invention is a synthetic insulation and finish system that is used on both residential and commercial structures, including the exterior and interior walls. More specifically, the present invention is in the field of synthetic stucco and the like. In addition, the present invention includes novel hardboard siding waterproofing, hardboard/wood siding retrofitting, architectural moldings and ceiling tiles that are coated with an elastomeric coating, preferably an aromatic and/or aliphatic polyurea.

Claims

1. A method for retrofitting an exterior surface of a house or building comprising:

attaching a foam board to an exterior surface of a house or building such that an inner surface of the foam board is adjacent to the exterior surface of the house or building, wherein the inner surface of the foam board has a surface profile that is a mirror image of the exterior surface of the house or the building; and

applying a first coating on an outer surface of the foam board, wherein the first coating comprises a polyurea formed by reacting (A) one or more polyether diamines and polyether triamines with (B) one or more isocyanates.

2. The method of claim 1, wherein the step of applying the first coating is prior to the step of attaching the foam board to the house or building.

3. The method of claim 1, wherein the foam board comprises polystyrene foam, polyurethane foam, or polyethylene foam.

4. The method of claim 1, wherein the foam board comprises expanded foam, extruded foam, or a combination thereof.

5. The method of claim 1, wherein the foam board is attached to the house or building by one or more adhesives, nails, screws, or a combination thereof.

6. The method of claim 1, wherein the foam board is attached to the house or building by one or more adhesives, wherein at least one adhesive comprises polyurea.

7. The method of claim 1, wherein the exterior surface of the house or building comprises oriented strand board, plywood, brick, concrete, masonry, wood, cement board, metal, tile, glazed brick, glazed unit masonry, exposed aggregate finish, fire retardant board, or hardboard.

8. The method of claim 7, wherein the exterior surface of the house or building comprises hardboard.

9. The method of claim 1, wherein the first coating is sprayed onto the outer surface of the foam board.

10. The method of claim 1, wherein the first coating comprises an aliphatic polyurea and at least one of a filler and a pigment.

11. The method of claim 1, further comprising:

applying a second coating onto an outer surface of the first coating;

wherein the first coating comprises an aromatic polyurea, and the second coating comprises at least one of a filler and a pigment.

12. The method of claim 10, wherein the filler comprises at least one of sand, glass, fibers, calcium carbonate, coal, granite, silica, clay, talc, mica, ceramics, flame retardants, multicolored quartz, and sea shells.

13. The method of claim 11, wherein the filler comprises at least one of sand, glass, fibers, calcium carbonate, coal, granite, silica, clay, talc, mica, ceramics, flame retardants, multicolored quartz, and sea shells.

14. The method of claim 1, wherein the polyurea is formed by reacting (A) one or more polyether diamines and polyether triamines with (B) diphenylmethane diisocyanate.

15. the method of claim 1, wherein the first coating has a coating thickness of from about 60 mil to about 75 mil.

16. A retrofitted building made by the method of claim 1.

17. The method of claim 1, wherein the exterior surface is a wall of the house or building.

18. The method of claim 1, wherein the polyurea is formed by reacting one or more polyether diamines and polyether triamines, one or more diethyltoluenediamines, and N,N′

-di-sec-butyl-4,4′

-methylene dianiline with one or more isocyanates.

19. The method of claim 1, wherein the one or more polyether diamines and polyether triamines comprise at least one of

wherein x is equal to 33.1, and

wherein (x+y+z) is equal to 81.

20. A method for retrofitting an exterior surface of a house or building comprising:

attaching a foam board to an exterior surface of a house or building such that an inner surface of the foam board is adjacent to the exterior surface of the house or building, wherein the inner surface of the foam board has a surface profile that is a mirror image of the exterior surface of the house or the building;

applying a first coating on an outer surface of the foam board; and

applying a second coating onto an outer surface of the first coating;

wherein the first coating comprises an aromatic polyurea, and the second coating comprises at least one of a filler and a pigment.

21. The method of claim 20, wherein the filler comprises at least one of sand, glass, fibers, calcium carbonate, coal, granite, silica, clay, talc, mica, ceramics, flame retardants, multicolored quartz, and sea shells.

22. A retrofitted building made by the method of claim 20.

23. The method of claim 20, wherein the exterior surface is a wall of the house or building.

24. The method of claim 23, wherein the wall of the house or building comprises hardboard.

25. The method of claim 20, wherein the aromatic polyurea is formed by reacting (a) one or more polyether diamines, (b) one or more polyether triamines, (c) one or more diethyltoluenediamines, (d) N,N′

-di-sec-butyl-4,4′

-methylene dianiline, and (e) one or more isocyanates.

26. The method of claim 25, wherein the one or more polyether diamines comprise at least one of

wherein x is equal to 33.1; and the one or more polyether triamines comprise at least one of

wherein (x+y+z) is equal to 81.

27. A method for retrofitting a wall of a house or building comprising:

attaching a foam board to the house or building, wherein an inner surface of the foam board is facing the wall of the house or building; and

applying a first coating on an outer surface of the foam board, wherein the first coating comprises a polyurea.

28. A retrofitted building made by the method of claim 27.

29. The method of claim 27, wherein the polyurea comprises an aliphatic polyurea and at least one of a filler and a pigment.

30. The method of claim 27, wherein the method further comprises:

applying a second coating on an outer surface of the first coating;

wherein the first coating comprises an aromatic polyurea, and the second coating comprises at least one of a filler and a pigment.

31. The method of claim 29, wherein the aliphatic polyurea is formed by reacting (a) one or more polyether diamines, (b) one or more polyether triamines, and (c) one or more isocyanates.

32. The method of claim 31, wherein the one or more polyether diamines comprise at least one of

wherein x is equal to 33.1;
