Gap between bathroom sink & wall...

[Davey Cammack]

Im having difficulty coming up with a viable option to fill in the gap between the bathroom sink & the wall. The cap is about 2 in deep & 1 inch wide. The wall has wooden panels painted but the water from the sink spills over into the gap & is starting to make the wooden surround for the sink on that side rot. I have tried window putty & it is supposed to dry & be water repellent within 29 days but its been 3 months now & it's still very wet. So i have removed it & cleaned it all away.

So my question is, what can i use to fill in the cap that will allow me to shape it at the front of the sink as it bends away from the wall so i can blend it in to the wall & sink & be water repellent & allow me to paint over it + bond with the ceramic side of the sink.

I considered polycell filler but i don't want to find out after its dried it didn't bond & still leaks water.

Any help would be appreciated.

Thanks

If you go to one of the smaller companies that makes up uPVC windows you should be able to get some off-cuts that will do the job nicely.

Based on what you have posted, sounds as if you need a 2x1" strip to fill up the gap - you can use silicone to fix it with.

Then either fix a thin strip horizontally to finish off with (i.e. a capping over the top, preferably sloping towards the sink so that any water drains the right way), or once the silicone used to fix the 2X1" block is set, just finish off the top with white silicone.

If you have a camera phone, take a pic of it with you, and they should be able to pick out some ideal off-cuts for the job.

Polyfilla, wood, etc, will just absorb water over time, and end up going mouldy.
