A paint roller assembly is provided comprising a handle, first and second arms supported by the handle, a substantially cylindrical first paint roller rotatably supported by the first arm and a substantially cylindrical second roller rotatably supported by the second arm, whereby the two rollers are spaced from each other such that the first roller can rotate without contacting the second roller. Using this and similar paint roller assemblies, the painter can implement the method embodiment of the invention, by dipping only the first roller in a supply of paint and then contacting the wall with the first roller to apply paint to a region of the wall. The first roller is then removed from the wall and the painter rotates the assembly to position the second roller at the wall whereupon only the second roller is rolled over at least a portion of the region previously painted with the first roller. Thereafter, the painter withdraws the paint assembly from the wall, rotates the assembly and dips only the first roller in the supply of paint, whereupon the foregoing method steps are repeated for successively different regions of the wall.
