Filling the Expansion gap in Laminate flooring - Silicone?

[cm786]

Hi everyone ,

I recently visited my uncles house who has had laminate flooring fiitted by a professional company. The install was very good as expected, with beading used to cover the expansion gap etc. The thing I found suprising was that around hard to cut things like pipes and the door frame where you can not use beading, they had just filled the gap in with some brown looking silicon(?). It looked good, but I was wondering that surely this means the floor can no longer expand/shrink with the gap filled in? Is this stuff flexible?

I'd like to do the same at my house to tidy up a few bits where beading just doesn't go.

Thanks for any advice,
Anees

You are supposed to cut the door frames etc and slide the floor underneath it when you can't use beading.
Silicon is flexible, but not a nice finish.
