Sealing skirting board to click vinyl flooring

[WWilts]

How to seal skirting board to click vinyl flooring (expands and contracts with underfloor heating)?

Sealant? 
Expanding tape?
Other?

Do you have a large enough gap for the expanding foam taple like https://qualitape.co.uk/expanding-foam-tape/?

 

I've used decorators caulk before and it has cracked over time with movement. Silicone sealants would last better but are more messy than I like and can't be painted over.

I tried the white 20mm wide draught excluder foam but it turned yellow very quickly, does the job but between white skirts and oak floor I can’t unsee it.

There are plenty of Hybrid silicone/adhesives these days which are also paintable but will stretch with the expansion/contraction.

 

id go for one of these if I were doing that task
