Best Plinth/Tile gap filler

[andmort]

I've just fitted a new kitchen on top of old terracotta tiled floor kitchen. Of course the tiles are uneven and there are quite large gaps between the bottom of the wooden plinth fitted to kitchen base units and the tiles themselves. Is there a good product to use to fill that gap? Decorators caulk doesn't seem robust enough as its a kitchen floor and therefore may be wet and mopped etc. Thanks.

A self adhesive strip may work dependant on the colour of your floor or plinth. Have a look at the link :

These will take up about 3-4mm but may still not be enough if its handmads teracotta

Thanks for replies. I don't think the foam would be suitable when it comes to mopping up the floor. The seal looks good and I might have gone with that, but of course the plinths are all fitted puttied and caulked in and painted now. Additionally the tile edges and grouting are so uneven I'm not sure if that product would seal it.

I'm thinking of something like decorators caulk, but more robust. Do people sometimes fill that gap with wood putty or something like plaster?

thanks.

The only way I could see to do this properly, would be to scribe the plinth to the floor. To be quite honest, the floor should have been levelled before the kitchen was installed. I don't know what sort of maximum gap your looking at, but as the floor will be mopped occasionally, perhaps some sort of silicone sealant would be best ?
If the gaps are very big, then I would suggest scribing the plinth to the floor then running a bead of silicone sealant along afterwards.

Have slate floor and gaps under plinth but never had reason to fill them.

This is what I used in a similar situation: http://www.uksealants.co.uk/product.asp?idproduct=169 (my plinth is white - clear may be more suitable for you)

The best way to do it is run a length of masking tape along the floor as this will follow the contours of the uneven tiles. You could also run a length on the bottom of the plinth. This will allow you to get plenty of sealant right into the gap without any mess. Smooth over and remove the excess and tape immediately then smooth lightly again with a wet finger.

I know that using tape is regarded as an amateur measure, but in this instance it will leave you with a watertight seal that looks as if the plinth has been scribed to perfection.
