Camaro vinyl flooring

[Bod ...]

Anyone with experience of luxury vinyl flooring?

I've had Camaro vinyl flooring planks put down in my lounge..

All looks good but there are some gaps between the tiles

I can get my finger nails in between. A mate of mine did this and I think he will try and fob me off.

Is there anything that can be done to make this a peaceful end?

I thought about Colorfill that you use for kitchen worktops.
