New Zealand! You live in paradise! Porch paint is specially made paint for wooden porches or decks. Its not a stain but an actual hard wearing & weather resistant paint that allows the wood texture to show through. Its safe for indoor or outdoor use. It is self priming & self sealing. I have used porch paint for wood paneling & kitchen cabinets & when remodeling a staircase formerly covered with carpet. It comes oil based or water based acrylic. I prefer oil based for a glossy easy to clean finish for a wooden table top. You may check your local home improvement/hardware store or paint store. I use Glidden Porch Paint. Takes me only 2 coats for white & the oil based goes on easily with a roller. Dries quickly too. Good luck!

Wax is good on a dining table as easy to apply a bit more in the event of cup rings etc.

Hi Jennifer K, thanks for your comments. The photos you have posted are really lovely but not really suited to our environment and house, which I know is impossible to tell from one photo. We have built a modern farmhouse on 10 acres. That room looks out to beautiful green countryside and the river below. The dining room is a bit of a feature and is completely different to the rest of our relaxed lodgey style house but I don't want it to be too modern, if that makes sense. The photos have given me a few ideas so thank you so much for your help!

Round! Just as elegant as a square table, but with so much more flow in a small room.
