In another embodiment, a system comprises a first crown element, a second crown element, and a spline configured to couple with the first crown element and the second crown element. In another embodiment, a system comprises a crown spline, a baseboard spline, and a wall element configured to be coupled with the crown spline and the baseboard spline. Other embodiments are disclosed herein.

A trim piece for sealing a work surface including a body having a first side, a second side, and a span disposed between the first side and the second side, wherein the first side and the second side are joined at a junction defining an angle between the first side and the second side of between 80 degrees and 100 degrees, a topcap is affixed to the span of the body, wherein the topcap includes a left side having a first wing and a right side having a second wing, an adhesive is bonded to the first side of the body and an aperture is disposed within the body.

The invention provides an elongated lighting element (200) for attachment to a building part (10) selected from the group consisting of a wall (11), a ceiling (12) and a floor (13), wherein the building part (10) comprises a first attachment unit (131) and a first electrical power connector (141), wherein the elongated lighting element has a front side (210) and at the other side of the front side (210) (i) a second attachment unit (231) for forming with the first attachment unit (131) said attachment to said building part (10), (ii) a second electrical power connector (241) for forming an electrical connection with the first electrical power connector (141), and (iii) a plurality of solid state based light sources (250) configured to provide light source light (251) and functionally connected with the second electrical power connector (241).

A system for installing pre-painted moldings. The system includes pre-painted moldings each configured to be fastened to a wall by fasteners. The system also includes a caulk material, filler material, concealer material, and touchup paint each color matched to the paint color applied to the moldings. The caulk material is configured to fill a gap defined between each of the moldings and the wall to which the molding is fastened. The filler material is configured to fill a gap defined between any abutting portions of the moldings. The concealer material is configured to conceal any surface disturbances caused by the installation of the fasteners. The touchup paint is configured to adhere to the paint pre-painted on the moldings. The system may also include a marker configured to apply a coating color matched to the paint applied to the moldings, a scraping tool, and/or a buffing tool.

Wall bases and methods for utilizing the same are provided. A rear surface of the wall base is configured to be secured to an adjacent forward surface of a wall. An extension member extends outward and downward from the base member, and a protrusion extends downward from the extension member. A channel for sealant is defined, at least in part, by the extension member and the protrusion. The protrusion may be separately formed from the extension member and base member.
