I usually use Bonakemi varnish who are Swedish and Europes biggest floor polish manufacturer. They also make Carl's Oil, a natural oil finish for hardwood floors that deepens the colour. I also use Junckers varnish (europes biggest wood floor manufacturer). Other possiblities are oils and hardwax oil made by Osmo very natural product, completely harmless to children and animals when dry (they all are of course but Osmo point it out on the tin...). Below, three examples of typical stains and varnish.
		Dark Oak Stain	Standard Yellow Pine
		Medium Stain	Suppliers
