Abstract

The invention relates to an up-stand joint seal 10 to make a waterproof joint between a shower tray or bath and adjacent wall (60 figure 9). The seal comprises a flexible strip 11 having an upper boundary 12, a lower boundary 13, an inner face 14 and an outer face 15. The inner face has an upper region 19 and a lower region 17. The outer face has an upper region 18 and a lower region 16. A removable tape liner 20 extends longitudinally over an adhesive bed 22 on the strip inside face. A further liner 31 covers another adhesive bed 32 on the outer face 15 which provides a means for fixing the seal to a wall. Both liners extend upwards and downwards past the adhesive beds and once the seal is applied to the wall and liner 20 is removed, wall covering adhesive (40 figure 9) will also be removed to create a space (55 figure 9) between the upper edge of the adhesive bed 22 and the lower edge (42 figure 9) of the outer wall covering adhesive 40. The created space thereby prevents capillary action by water.

Description

UP-STAND JOINT SEAL

The present invention relates to an up-stand joint seal adapted to provide an enhanced waterproof connection between two substrates such as the joint between a wall and adjacent shower tray or bath ledge or work surface.

Prior art relating to up-stand joint seals adapted to seal the joint between a shower tray feature up-stand strip membranes with a high tack pressure sensitive butyl adhesive tape longitudinally applied to a lower portion of one side. During installation the adhesive strip is exposed and bonded to the shower tray perimeter side wall before installation of the tray against the intended shower wall.

A first problem with these product types as disclosed in EP1967107B1 is that failure of the sealant applied between the tile and ledge results in water ingress and soakage up the tile adhesive through capillary action and osmosis causing property damage.

A second problem contributing greatly to the first problem is that joint movement causes sealant applied between the tile and ledge to fail causing water ingress and soakage up the tile adhesive through capillary action and osmosis causing property damage.

A third problem particular to up-stand seals reliant on hot melt self-adhesives such as butyl and other elastomeric materials as the primary means of strip construction and connection to shower trays or baths is that such adhesives can react aggressively to silicone sealants. Separation gaps, voids and gap fillers are required to prevent such reactive contact as apparent in EP1967107B1 Figures 4 (tile gap) and 8(cavity/void). These gaps and voids promote the passage of water and pooling which feeds the capillary action.

It is the object of this invention to limit or eliminate the aforementioned problems

associated with prior art up-stand seals.

According to the present invention there is provided an up-stand joint seal adapted to be installed as a component of a shower tray or bath perimeter joint sealing system, in the installed orientation comprising of: a flexible longitudinal strip having a strip upper boundary and a strip lower boundary between which strip boundaries there extends a strip inner face facing the ledge and a strip outer face facing the wall which strip outer face has a strip outer face upper region and a strip outer face lower region and which strip inner face has a strip inner face upper region and a strip inner face lower region: a tape extending longitudinally on the strip inside face comprising of tape adhesive liner and a tape adhesive bed and which tape adhesive liner has an upper boundary and a lower boundary between which tape adhesive liner boundaries there extends a liner inner face facing the ledge and a liner outer face facing the wall: characterized in that the tape or part thereof provides a means of fixing the position of the wall adhesive lower most boundary to limit or prevent the effects of capillary action.

In addition, the tape or part thereof further provides a means of bonding a backer material to the strip to limit or prevent the effects of capillary action and enhance the capacity of the up-stand joint seal to accommodate joint movement.

In addition, tape or part thereof further provides a means of releasable engagement between tape or part thereof and a provisional fixing tape adhesive bed extending longitudinally on the opposing strip outer face.

Said means of fixing the position of the wall adhesive lower most boundary is through the removal of the tape after application of the wall adhesive over the tape adhesive liner inner face resulting in the simultaneous removal of wall adhesive lying on and below the tape adhesive liner upper boundary thus raising the position of the original wall adhesive lower boundary to a new wall adhesive lower boundary to limit or prevent the effects of capillary action.

Alternatively, said means of fixing the position of the wall adhesive lower most boundary is through the tape adhesive liner outer face being releasable off the tape adhesive bed after application of the wall adhesive over the tape adhesive liner inner face resulting in the simultaneous removal of wall adhesive lying on and below the tape adhesive liner upper boundary thus raising the position of the original wall adhesive lower boundary to a new wall adhesive lower boundary to limit or prevent the effects of capillary action.

Ideally, said means of bonding a backer material to the strip is through the removal of tape adhesive liner to expose tape adhesive bed with which to bond backer foam or such like material onto the strip inner face to limit or prevent the effects of capillary action and enhance the capacity of the seal to accommodate joint movement.

Preferably, said means of releasable engagement between tape or part thereof and a provisional fixing tape adhesive bed extending longitudinally on the opposing strip outer face, is through tape adhesive liner outer face and inner face being siliconized and releasable off the tape adhesive bed and the provisional fixing tape adhesive bed respectively when the up-stand joint seal is wound and supplied in roll format.

Ideally, after installation of the up-stand joint seal onto the wall, and after final location of the shower tray against the strip inner face, the tape adhesive liner lower boundary extends substantially adjacent to the level of the ledge and below the wall adhesive lower boundary after initial application of the wall adhesive.

Advantageously, removal of tape adhesive liner exposes the tape adhesive bed as a means to bond backer foam onto the strip inner face and create an anti-capillary cavity or an anti-capillary sealant reservoir to limit or prevent the effects of capillary action.

An up-stand joint seal may act in combination with provisional fixing tape adhesive bed that extends longitudinally on the strip outer face to provide a preliminarily means of part engagement of the strip with the wall in preparation for the subsequent application of a permanent adhesive bed to facilitate a permanent engagement of the opposing strip outer face with the wall.

Alternatively, a provisional fixing tape adhesive bed liner extends over the provisional fixing adhesive bed.

Ideally, tape liner and provisional fixing tape adhesive bed liner are of polyethylene or polypropylene material and each siliconized on one or both sides.

Ideally, strip is a flexible polymeric material such as 100-300 micron polyethylene or polypropylene or a heavier polymer material.

Interestingly, a means of tenacious engagement between the strip and adhering materials is achieved through surface etching and/or the application of a silicone film over part or whole strip surface.

Alternatively, a means of tenacious engagement between the strip and adhering materials is achieved through one or more longitudinal regions of the strip being laminated with a rough fleece material.

Preferably, the up-stand seal acts in combination with a close celled backer material or the like that may be compressible and round or linier in section.

Preferably, the up-stand seal acts in combination with a sealant adhesive of the type that may be extruded uncured from a tube, applied as desired and thereafter cure as flexible sealant adhesive.

Preferably, the up-stand seal acts in combination with overlapping waterproof wall matting or a liquid applied waterproof membrane.

Preferably, the up-stand seal acts in combination with a wall adhesive (40).

One installation method is characterized in the removal of tape after application of the wall adhesive and the creation of an anti-capillary cavity.

An alternative installation method is characterized in the removal of adhesive tape liner after application of the wall adhesive and the creation of an anti-capillary cavity or an anti-capillary sealant reservoir.

Yet another installation method is characterized in the removal of the adhesive tape liner before the application of the wall adhesive.

The invention will hereinafter be more particularly described with reference to the accompanying drawings, which show by way of example only, some embodiments of the seal according to the invention. In all figure descriptions the term inner face' should be understood to define a material surface facing the shower tray or bath after installation and the term outer face' should be understood to define a surface material facing the wall after installation.

Figure 14 represents a section view Figure 13 after installation.

Referring to the drawings in detail: Figures 1 and 2 of the drawings disclose an up-stand joint seal 10 comprises of a flexible longitudinal strip 11 and tape 20. In Figure 1 the invention is provided in roll format for transport and Figure 2 is a section drawing in its installed orientation.

The flexible longitudinal strip 11 has an upper boundary 12 and a lower boundary 13 between which boundaries there extends an inner face 14 facing ledge 92 and an outer face 15 facing wall 60. The strip outer face 15 has an upper region 18 and a lower region 16. The strip inner face 14 has an upper region 19 and a lower region 17.

The tape 20 extends longitudinally on the strip inside face 14 and comprises of tape adhesive liner 21 and tape adhesive bed 22. The tape adhesive liner 21 has an upper boundary 23 and a lower boundary 24 between which tape adhesive liner boundaries there extends an inner face 25 facing the ledge 92 and an outer face 26 facing the wall 60.

The component parts detailed in Figures 1 and 2 are identically presented in Figures 3 and 4. In addition, Figures 3 and 4 disclose provisional fixing tape 30. Provisional fixing tape 30 extends longitudinally on the strip outside face 15 and comprises of provisional fixing tape adhesive bed liner 31 and provisional fixing tape adhesive bed 32.

Tape adhesive liner 21 and provisional fixing tape adhesive bed liner 31 may be of polyethylene or polypropylene material siliconized on one or both sides. Typically, the strip 11 is a 200-300 micron soft polyethylene or polypropylene type material but could be a heavier polymer material. Adhesive beds 22 and 32 are typically hot melt adhesives.

Component parts detailed in Figures 3 and 4 are presented in Figures 5 and 6 with the omission of provisional fixing tape adhesive bed liner 31. Figure 5 also differs in orientation from Figures 1 and 3 in that the strip outer face 15 now faces the roll center (core). In Figures 5 and 6 provisional fixing tape adhesive bed 32 is aligned to engage tape adhesive liner inside face 25 during the roll winding process. Tape adhesive liner 21 is thus employed a release liner common to tape adhesive bed 22 on its outside face 26 and provisional fixing tape adhesive bed 32 on its inside face 25. This roll format provides three key benefits.

Firstly, installers can mount strip 11 directly onto wall 60 without having to progressively remove provisional fixing tape adhesive bed liner 31. Secondly, the use of double siliconized face tape adhesive liner 21 in this manner decreases roll thickness typically amounting to 60 microns/revolution. Thirdly, the engagement of provisional fixing tape adhesive bed 32 directly onto the opposing tape adhesive liner inside face 25 increases roll stability dramatically.

It should be understood though not presented in the drawings, that the strip inner and outer faces 14 and 15 respectively may be enhanced to form tenacious adhesive bonds with sealant adhesives and mechanical bonds with wall adhesives.

In respect of the use of sealant adhesives, such an adhesive bonding enhancement may be achieved through whole or part siliconization of plasma/corona etched surfaces of the strip 11. In respect of wall adhesives, such a mechanical bonding enhancement may be achieved through the provision of a rough non-woven fleece layer glued to strip 11.

Further material features disclosed in cross section Figures 7-14 are a wall 60, a wall covering 70 having an inner face 73 and outer face 72 and a wall covering bottom edge 71, a shower tray 90 having a ledge 92 and shower tray perimeter side wall 91. Close celled backer foam 80 and 81 is waterproof, flexible and compressible. Wall adhesive 40 may be class 2 cement based and the adhesive sealant 50, 51, 52, 53 may be silicone based. Adhesive bed 33 bonding backer foam 80 to shower tray 98 may be a hot melt transfer adhesive.

Installation methods and further invention features will now be detailed with references to Figures 7-14. All measurements are given by way of example only and may vary.

Firstly, general procedures common to these various installation methods being disclosed begin with marking the proposed location of the strip upper boundary 12 on walls 60 against which strip 11 is being bonded. This wall mark in the case of a 100mm wide strip 11 being installed, may be 70mm above the ledge when the shower tray is installed leaving the tape liner lower boundary 24 substantially adjacent the shower tray ledge 92.

Masking tape may be applied to the wall on and over this wall mark. The provisional fixing tape adhesive bed liner 31 (if pre-applied) is progressively removed to expose provisional fixing tape adhesive bed 32, the strip upper boundary 12 is aligned against the masking tape and the strip 11 is bonded to the wall 60 ensuring fill contact in wall corner joints.

Thereafter, the strip outside face upper legion 18 is pulled back and permanently bonded to wall 60 by means of sealant adhesive 50 or a wall adhesive 40.

A bed of 7mm-l2mm wide hot melt transfer adhesive 33 is applied to a cleaned shower tray perimeter side wall 91 approximately 7-9mm below the level of ledge 92 and a 4-6mm round close celled backer foam 80 is bonded to the shower tray perimeter side wall 91.

The shower tray 90 is then located in its final resting position against the strip inner face lower region 17 compressing the backer foam 80. Adhesive sealant 51 is applied into the joint between the shower tray 90 and adjacent strip inner face lower region 17 and rubbed up rising outwardly from ledge 92 (to prevent pooling) to form a watertight seal.

Figure 7 details the completion of these common installation procedures described above.

There are various ways of completing the installation and these will now be explained by way of reference to Figures 7-14.

In Figure 8 the wall adhesive 40 is applied over strip 11 and tape liner 21. The wall adhesive terminates at its lower boundary 41.

As shown in Figures 9-12, removal of tape liner 21 in Figure 8 simultaneously exposes tape adhesive bed 22 to which is bonded backer foam 81 to engage the strip 11. As shown in Figures 9, 10, 13 and 14 wherein wall adhesive was applied over the tape adhesive liner 21, removal of tape liner 21 as shown in Figure 8 simultaneously removes the attached wall adhesive 40 raising the position of the original wall adhesive lower boundary 41 in Figure 8 to new adhesive lower boundary 42 in Figures 9, 10, 13 and 14.

To complete the installation detailed through Figures 7-9, the wall covering 70 is bonded to the wall adhesive 40 creating anti-capillary cavity 55 in the process. The joint between the ledge 92 and wall covering bottom edge 71 is sealed with sealant 52. The anti-capillary cavity 55 limits or prevents capillary action while the backer foam 81 enhances joint flexibility.

To complete the installation detailed through Figures 7, 8 and 10, adhesive sealant 53 is applied into the anti-capillary sealant reservoir 56 (as the wall covering 70 is bonded to the wall adhesive 40) to form a watertight anti-capillary sealant bridge 53 between the strip inner face 14 and wall covering outer face 72. The joint between the ledge 92 and wall covering bottom edge 71 is sealed with sealant 52. The anti-capillary sealant bridge 53 prevents capillary action while the backer foam 81 enhances joint flexibility.

The installation method detailed through Figures 7, 11 and 12 differs from that detailed in Figures 9 and 10 in that backer foam 81 is bonded to the strip inner face 14 before the application of the wall adhesive 40. As shown in Figure 11, this creates an anti-capillary sealant reservoir 56 formed between the backer foam upper surface 82 and strip inner face 14 (also shown in Figure 10).

A fillet of adhesive sealant 54 is applied into anti-capillary sealant reservoir 56. Wall adhesive 40 is applied over the strip inner face 14 and over the fillet of adhesive sealant 56 which shutters the wall adhesive 40 forming its lower boundary 43. The wall covering is bonded to the wall adhesive 40 during which process the lower most outer face 72 edge of the wall covering may receive a small bead of sealant to engage the fillet of adhesive sealant 56 when being pressed onto the wall adhesive 40.

It should be understood that the omission of the fillet of adhesive sealant 54 is possible in this installation method whereby the backer foam upper surface 82 would alternatively act to engage and shutter the wall adhesive 40 forming its lower boundary 43.

To complete the installation detailed through Figures 7, 11 and 12, the joint between the ledge 92 and wall covering bottom edge 71 is sealed with sealant 52. The anti-capillary sealant bridge 54 prevents capillary action while the backer foam 81 enhances joint flexibility.

Figures 7, 13 and 14 detail the outcome of an installation that is similar to Figure 9 outcome, but wherein tape 20 is entirely removed and the backer foam 81 is inserted into the joint between the ledge 92 and wall covering bottom edge 71 after the wall covering is bonded to the wall adhesive 40. The removal of tape 20 is easily achieved through adjacent strip inner face 14 being a siliconized surface.

During installation, a joint spacing material such as a tile spacer or foam 75 is used to support the wall covering 70 while the adhesive 40 cures. To complete the installation detailed through Figures 7, 13 and 14, the joint between the ledge 92 and wall covering bottom edge 71 is sealed with sealant 52 and as in Figure 9, the anti-capillary cavity 55 limits or prevents capillary action while the backer foam 81 enhances joint flexibility.

The installation methods detailed above are each provided a means of fixing the position of the wall adhesive lower most boundaries 42 and 43 to limit or prevent the effects of capillary action. Figures 9-12 is also provided a means of fixing waterproof backer foam 81 to the strip inner face 14 and that also serves to limit the effects of capillary action and enhance the capacity of the up-stand joint seal to accommodate joint movement. Figure 5 provides a means of means of releasable engagement between tape 20 or part thereof and provisional fixing tape adhesive bed 32.

Up-stand joint seal 10 can be installed as a stand alone up-stand joint seal, but it is intended to be installed as core component of complete waterproofing systems developed for installation over shower trays and baths. Such tanking systems will also include a waterprooflng solution for wall surfaces and wall corner joints such as fleeced polyethylene or polypropylene matting and liquid applied waterproofing membranes.
