Silicone sealant
Just fitted a new bath and there is a gap between the bath and the two end
walls of approx 1.5cm. Will Silicone fill this size gap, and to what depth? Or should I use some other type of filler with a silicone 'top coat'? When the walls have been tiled, I'll be adding an L shaped seal anyway, but I thought the extra sealant/filler would add to rigidity/stability. Thanks. |

I would not bother sealing it until the tiles are in place - that will stop water getting behind them. It will also reduce the 1.5cm to something a bit more managable. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Firstly apologies for a total lack of information but
I was watching a programme the other day and they looked at a man who had given up his job and invested his savings to market a moveable bath sealer, it was a white moving plastic fitting that moves up and down. I think that it was on the money programme but I am not sure - I will search but hopefully someone else will have seen it. It certainly seemed to offer an alternative to silicon sealant. |

For a gap that width I'd recommend using a bath seal strip which will sit on the wall and you put your tiles over it. Have a look at this page: http://www.tradetiler.com/acatalog/Plastic_Trims.html |

Wouldn't slight movement in the bath cause stress on the tiles? I guess I was hoping that filling the gap with silicone would add stability. The bath doesn't move that much, in fact after screwing the legs to the floor, and a couple of wall brackets, I only know it does move a little because I've _tried_ to move it. |

Draw a line on the wall with a pencil exactly where the top edge is, then fill the bath with water and draw another line - you'll be amazed how far it moves. A bath full of water weighs a huge amount ! The bath itself flexes, the floor will go down a bit, and the leg structure will compress - it all adds up. Best case is a cast iron bath on a concrete floor. Worst case is an acrylic bath on a chipboard floor ! Andrew Mawson |

Graeme,
I had a similar situation and used a bath seal as suggested by BigWallop - i.e. seal with tiles over it. In my case it was an acrylic bath on traditional floorboards. The only precaution I took was to fill the bath with water before fitting the seal and putting on the tiles - when the tile cement had dried, I emptied the bath. That was 5 years ago and I've had no problems at all. The bath does settle down with the weight of the water, but the seal is designed to compensate a certain amount. In my case, I've seen no evidence of stress on the bath or tiles. I'd use it again. Murdo "Graeme" wrote in message ... "BigWallop" wrote in message ... "Graeme" wrote in message ...

Thanks. shape a bit of wood to fit, coat it liberally in superglue, and tap it into position,. NOW use silicone sealant... |

Have a chat with Dow Corning Technical for a product with high movement capability
(possibly 791 ?) I think it can tolerate 50% or more and there may be better ones. If the bath moves more than 2 or 3 mm though that would be excessive and attention would need to be paid to e.g. the floor and mounts. Nick |

Hi, Also the silicon seal needs to be some multiple of this and to have the right depth and a bond breaker behind it if necessary. cheers, Pete. |

I had assumed that the bath would move a.little depending on the amount of water and people (;-) that are in it. I did your experiment of drawing a line with the bath empty, and then full. The lines are in exactly the same place! Not 0.5mm difference. This is an acrylic bath on chipboard (although the bath's feet are directly over the joists). |

Graeme, I'm glad to hear it but a bit suprised ! Maybe the joist span is very small ? or is it a very small bath ? - anyway it's good news for the longevity of your seal !

So am I to assume that 5/8" is way too much? Why? I'm sorry about all that. If there is a 15mm gap from the bath to the wall you will need to put something in there. The silicon is a liquid until it sets it will flow down the wall. It will fill smallish gaps as it is quite viscous and sets fairly quickly. A strip of 1/2" wooden (or plastic or some other sort of) beading will do. Stick it on with silicon if you like.* Then run a stream of silicon along the now diminished gap. Make sure the outlet is large enough for the strip you want to lay, by cutting the nozzle at a suitible diameter and cut it with a slight angle. Each time you run a bead, wipe the nozzle clean until you get the hang of it. When using the gun, remember it will keep coming out after you have stopped squeezing -so have some newspaper or a rag handy. Do a dry run or two to get the hang of the angle you want and rest part of the nozzle on one edge as you go. If you think you might louse it up, run a strip of tape either side of where you want the stuff to end up and rip it off after it will leave an excellent edge if you do it quickly and remove it straight away. Going too slowly is the surest way to foul up. Good luck and have fun. *You'd better not. Use No Nails -or a couple of tacks with the silicon. one more thing, buy the best mastic gun you can find. The cheapest ones are really naff and most of them are too small for the longer cartridges. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |
