A panel assembly covers a bearing surface. The panel assembly includes a panel and a plurality of panel supports. Each one of the panel supports includes a mounting plate, first and second panel edge engaging portions and a protruding rib engaging portion. The panel includes a first edge region, an opposed second edge region, a covering portion extending between the first and second edge regions, and at least one rearwardly protruding rib extending between the first and second edge regions. The first edge region, the second edge region, and the at least one rearwardly protruding rib of the panel are respectively engageable with the first panel edge engaging portions, the second panel edge engaging portions, and the protruding rib engaging portions of the supports. The panel assembly is translatable with respect to the panel supports when engaged together.

An improved mounting block has a base plate portion and a face plate portion. Base plate portion has an outer surface extending outward from a mounting surface and is selectively attachable to the face plate portion. One of the face plate portion and the base plate portion has a plurality of snap fit teeth formed thereon, and the other has a plurality of snap fit receivers, configured to selectively receive the snap fit teeth. Face plate portion may include flange flex grooves formed in an attachment flange, allowing walls to deflect independently from corners, such that the flange flex grooves allow the attachment flange to flex outward from the outer surface. Base plate portion may include alignment ribs extending outward from the outer surface, such that the flange flex grooves formed in the attachment flange interface with the alignment ribs formed on the base plate portion.

The invention is directed to a joint tape for finishing a joint between boards comprising a nonwoven substrate that does not swell substantially in the presence of water. The invention further provides a method of finishing a joint between boards comprising (i) applying a joint tape of the invention to a joint between boards by embedding the joint tape in a first coat of joint compound, (ii) applying a second coat of joint compound over the tape, wherein step (ii) is carried out before the joint tape and joint compound applied in step (i) have substantially dried, and optionally (iii) applying a third fill or finish coat of joint compound over the tape, wherein step (iii) is carried out before the joint tape and second coat have substantially dried.
