Silicon Around Floor Edge?

[EViS]

Do you guys Silicon around the perimeter of a tiled bathroom floor or grout?

I would have thought Silicon is the best option in the same way that Silicon should be applied to all room corners so as to allow for building movement (i.e. grout would crack).

Yes Silicon to allow for movement as you say. Normally a 2mm joint

 

[White Room]

I do like all internal corners

Super fast reply fellas! Thanks.

Also, I always buy mid-price range Silicon (usually Unibond stuff at £4.50) from Screwfix. What do you guys get? The stuff ranges from £2 to £20...

grout cracks can mean leaks,
silicon and its sealed tight and provides room for movement

I like the mapei sealer from screwfix for the coloured grouts but use everbuild forever white for standard applications

 

[united]

I generally use Mapei (mapisil AC) Silicon it's nice to work with and I can get the exact colour match with Mapei grouts

Mapesil AC

Whichever Silicon you choose to use, just make sure it is "high modulus".

Why high modulus?

 

[Daz]

I have just had a quick look for some facts, but drew a blank :mad2:, for now. However, my understanding is that a high modulus Silicon has greater anti-fungal and mildew resistance properties.

 

[Scott]

Ok i wasnt sure about it either so i looked as well! My understanding it the low modulus is more flexible and high is 'stiffer'. So probably ok for low movement ares like corners, wall to floor etc.

Didnt look into the antifungal side of it. Although i have to say i sealed my shower tray with Screwfix no nonsense Silicon 3 half years ago and its just starting to grow on it now, having said that its also growing on the grout too.
