An applicator as claimed in claim 1, wherein the hood partially encloses the roller. 6. An applicator as claimed in claim 1, wherein the head includes at least one passage defined in the hood. 7. An applicator as claimed in claim 6, wherein where there is more than one passage the passages are arranged in a row running parallel with the axis of the distribution means surface. 8. An applicator as claimed in claim 7, wherein the row of passages extends substantially the width of the surface. 9. An applicator as claimed in claim 7, wherein the row is shorter in length than the width of the surface, and each end of the row is not less than 25 mm from the corresponding end of the surface. 10. An applicator as claimed in claim 9, wherein the gap is at a minimum at or adjacent to the or each passage. 11. An applicator as claimed in claim 10, wherein the hood includes a concave internal hood surface. 12. An applicator as claimed in claim 11, wherein the hood has a different radius to the roller surface. 13. An applicator as claimed in claim 12, wherein the hood is of larger radius than the surface. 14. An applicator as claimed in claim 13, wherein the roller surface and the hood surface are not concentric. 15. An applicator as claimed in claim 14, wherein the roller surface and hood surface diverge away from each other about the passages. 16. An applicator as claimed in claim 15, wherein the head includes a recess defined in the hood, and the or each passage leads to the recess. 17. An applicator as claimed in claim 16, wherein the recess forms a plenum chamber. 18. An applicator as claimed in claim 17, wherein the recess extends substantially the width of the distribution means surface. 19. An applicator as claimed in claim 18, wherein each end of the recess is not less than 18 mm from the corresponding end of the distribution means surface. 20. An applicator as claimed in claim 19, wherein edges are defined where the recess meets the internal hood surface, and the gap is at a minimum at the edges. 21. An applicator as claimed in claim 20, wherein the distribution means surface contacts the edges. 22. An applicator as claimed in claim 21, wherein elongate projections are provided along the edges parallel to the roll axis of the roller, and the projections are rounded in form. 23. An applicator as claimed in claim 1, wherein the mounting means for the roller are adjustable, so that a minimum gap is adjustable. 24. An applicator as claimed in claim 1, wherein the mounting means allows the roller to be removed from the head. 25. An applicator as claimed in claim 1, wherein a paint trap is provided adjacent to the roller. 26. An applicator as claimed in claim 1, wherein there is a stop member to limit the bias means for control of the flow of paint. 27. An applicator as claimed in claim 1, wherein the bias means is associated with an extension handle to allow displaced or elevated operation of the applicator. 28. An applicator as claimed in claim 1, wherein the distribution means surface includes textures or patterns to facilitate paint distribution on the surface to be painted. 29. An applicator as claimed in claim 1, and comprising a paint container, and wherein the body includes holding means for the paint container. 30. An applicator as claimed in claim 29, wherein the paint container is formed of translucent material, to provide a visual indication of the amount of paint in the container. 31. An applicator as claimed in claim 29, wherein the paint container is removable. 32. An applicator as claimed in claim 29, wherein the paint container is elongate with an oval or rectangular cross-section with the major axis substantially aligned with a slot of the applicator. 33. An applicator as claimed in claim 1, wherein the body includes refilling means. 34. An applicator as claimed in claim 33, wherein the refilling means comprises a threaded end cap. 35. An applicator as claimed in claim 1, wherein the paint biasing means includes a plunger, which is movable to act on the paint in the body or the paint container such that as the plunger advances, the bias on the paint forces flow to the paint distribution means. 36. An applicator as claimed in claim 35, wherein the plunger includes rod means, which extends away substantially along the longitudinal axis of the body from a plunger head acting upon the paint. 37. An applicator as claimed in claim 36, wherein the body includes gripping means having a handle in the form of a tube having a passage therethrough. 38. An applicator as claimed in claim 37, wherein the rod means extends into and along the handle. 39. An applicator as claimed in claim 38, wherein the rod means extends beyond the handle and includes a gripping portion at its distal end by which the plunger is moved. 40. An applicator as claimed in claim 39, wherein the gripping portion includes a lateral extension, extending laterally beyond the handle. 41.
