Gap between floor tiles and wall tiles Fillers, sealants and adhesives for all types of DIY work. Help, advice and information on all aspects of this subject

[bezzas7]

Hi all,

There is a gap of say 5mm to 8mm give or take high between where the floor tiles meet the wall tiles in the bathroom.
The gap goes 3.5cm to 4cm back to the breeze block.

i'm guessing its the thickness of the dot and dab then plaster board, then tile adhesive then tile.

Problem is if i put some grout coloured silicon sealant down along the gap its just going to push into the gap.

So should i -

1 - Fill the gap with filler flush to the front with either pollyfiller or the large gap pollyfiller?

2 - Fill with tile grouting flush to the front?

3 - expanding foam?

4 - Fill with loads of silicone sealant?

5- Pack with paper\wood etc then seal?

And then use the grout coloured silicone sealant to finish off the job.

Not sure whats best?

Your help is very much appreciated.

Thanks

Andy

bezzas7,
Buy a pack of grout the same colour as the existing and fill the gap with this.

But won't the grout crack with general expanding\shrinkage? the floor tiles are laid on a chip board floor so there could be some movement there.

would filler be a good idea then finish with a bead of silicone?

bezzas7,
Suggest you try with just grout and if it cracks you can resort to silicone.
