A flexible inside corner trim piece is formed with concave depressions at hinge portions where wings attach to the body. The trim piece can be formed such that wings and a top cap lay flat in plane perpendicular to body or wings and top cap curve at an angle. Hinge portions can be narrow or wide and symmetrical or asymmetrical. The trim piece can be dyed, paintable, or present another decorative surface. The trim piece can include embedded lighting.

A system comprising a first baseboard element, a second baseboard element, and a spline configured to couple with the first baseboard element and the second baseboard element. Another system comprising a first crown element, a second crown element, and a spline configured to couple with the first crown element and the second crown element. Other embodiments are disclosed herein.

The invention relates to a method for arranging a flash coving profile in the transition between a floor and a wall, wherein the method comprises: providing an end element, the end element comprising a transition part having an outer surface, an upper edge and a first side, the first side to be placed against the first end of the metal sheet, and a wall fixator part, wherein the wall fixator part comprises a holding space to hold the upper edge of the transition part and the first edge of the metal sheet at its first end, fixing the wall fixator part to the wall, placing the upper edge of the transition part in the holding space of the wall fixator part and fixing the transition part to the floor and/or the wall, and placing the first edge of the flash coving profile at its first end in the holding space such that the first side of the transition part is placed against the first end of the metal sheet, and the outer surface of the transition part lies substantially flush with the flooring of the flash coving profile.

In one embodiment, a system comprises a first baseboard element, a second baseboard element, and a spline configured to couple with the first baseboard element and the second baseboard element. 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.

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.

Coping and skirting systems for structural bases are described herein. The coping and skirting systems include at least one coping tile and a support structure configured to be mounted on a front surface of the structural base and to support the at least one coping tile on the structural base. The support structure is also configured to be mounted on the structural base at a selectable position that provides for a top surface of the coping tile to be level with a top surface of a field tile on the structural base.

A flooring installation features flooring laid atop a subfloor in a position leaving a gap between at least one perimeter edge of said flooring and a respectively adjacent wall structure; and an edge moulding having a base stem and a cap, said base stem reaching downwardly into the gap between the flooring and the adjacent wall structure, said cap having an inner lip jutting inwardly over the flooring from said base stem. Double sided tape is disposed between, and adhered to both, the base stem and the wall structure to adhesively secure said edge moulding to the wall structure.

A flexible inside corner trim piece is formed with concave depressions at hinge portions where wings attach to the body. The trim piece can be formed such that wings and a top cap lay flat in plane perpendicular to body or wings and top cap curve at an angle. Hinge portions can be narrow or wide and symmetrical or asymmetrical. The trim piece can be dyed, paintable, or present another decorative surface. The trim piece can include embedded lighting.

Adhesive compositions are described that are suitable for securing building materials, such as TPO membrane roofing to a structural element, such as a roof deck. The adhesive compositions are very high-solids, wet-set adhesives that provide a peel strength that meets or exceeds industry standards, while requiring application to only one of two surfaces to be joined. The adhesive compositions comprise a liquid modifier with hydroxyl functionality, a chlorinated polyolefin and a silylated polymer. Methods of use are also disclosed.
