Read about the product – it can be a great way to refresh your floor.
As a side note: REFRESHER or any other topical coating should never be applied to laminate. It will not add value, in fact it will make your laminate harder to maintain and look worse.
This is a friendly tip for anyone who thought that refresher on laminate was a good idea.
