: : I agree with the OP - whan I tile to kitchen worktops I always use hardboard : as described to protect and provide a pocket for the silicone which gives a : much better seal. : : With baths the situation is slightly different as potentially there may be : movement with the varying weight of the bath in use. : : I still think that a corner fillet of silicone has far less adhesion than a : well filled groove of highly elastic (not sure what the elastic modulus is : of the"UNIBOND High Performance bathroom & : shower" ) sanitary silicone. : : Adrian : ........................... Thanks for that Adrian. I must say at this stage that the bath in question is firmly secured to a concrete floor and has been filled to see if there is any movement. I couldn't detect any distortion even after a few hours. I don't know what the modulus of this particular silicone is as it doesn't say on the tube, all I can tell you is that it is "Power Shower" silicone & "Superior Mould Resistant" with a 35 year guarantee. I agree with you on the small gap theory having a better adhesion and I am still pondering about fitting a UPVC quadrant as apposed too just having a silicone one. I might telephone UNIBOND, their techie guys are pretty good when I've asked about other various products. Any more thoughts good or bad, please post back. Regards. Mike.
