Definitions

• the present invention relates to a sealing strip adapted to be fixed onto a substantially vertical perimeter side wall of a shower tray or bath before final installation against a wall as a means to seal the joint between the shower tray or bath and an adjacent wall.
• the present invention also relates to an up-stand sealing assembly intended to be bonded onto a perimeter side wall of a shower tray or bath before final location against a wall as a means to seal the joint between the shower tray or bath and said adjacent wall.
• an adhesive tape bonds to an up-stand strip on one side and engages a release liner on the opposite face. During installation the adhesive tape release liner is removed and the exposed adhesive tape is then bonded onto the perimeter side wall of a shower tray or bath.
• FR2914548 A1 fig. 1 the release liner part 5A touch engages but is clearly not attached to non-woven band 3B.
• Release liner part 5A requires its connection with release liner part 5 (along dotted line 6) or it would instinctively remain releasably engaged to adhesive tape 2A when unrolled.
• a more direct and independent means of providing a release liner to engage exposed adhesive tape face 2A would simplify the product and eliminate the need for the removal of liner 5A during installation.
• silicone sealants can react aggressively with butyl adhesive membrane (2).
• the non-woven band laminated onto the butyl is only 0.1 mm thick fleece and will not prevent deformation of the butyl layer due to reactive silicones bleeding through the fleece onto the butyl. Also a problem is that butyl adhesive membranes (2) remain soft and pliable and are subject to 'creep' under the load of wall tiles.
• Prior art relating to up-stand sealing assemblies such as GB2467428 A detail a preformed high tack butyl adhesive tape longitudinally bonded to a lower section of an up- stand strip with an adhesive tape release liner covering the opposite adhesive tape side.
• the adhesive tape release liner is removed and the newly exposed adhesive tape upper boundary is aligned parallel with the shower tray/bath ledge and thereafter the whole adhesive face is bonded to the shower tray/bath perimeter side wall so that an upper section of the up-stand strip forms an up-stand above the ledge.
• the roller compression force required to bond the adhesive tape onto the up-stand strip can result in inconsistent adhesive tape outer edges particularly if the adhesive tapes outer edges were not uniform before hand which can be the case with butyl tape supplied in roll format.

• the neoprene cord may vary in cross section profile to accommodate the desired intention. It is also possible to combine alignment materials as shown in Figure 1 1.
• a first benefit of a soft neoprene cord type alignment material 390 is that when situated along the adhesive tape upper boundary 221 as shown, it provides additional compressible shuttering support to the adjacent adhesive tape upper boundary 221 when being pressed onto the up-stand strip inner face 214 during the manufacturing process. This results in a clean straight edge that the installer can clearly see during the installation process.
• a second benefit of a neoprene cord type alignment material 390 is that it serves as a bumper against inadvertent impacts that would otherwise deform the adhesive tape upper boundary 221 during transport and general (poor) handling prior to installation.
