I am currently building an extension oot the back of the house(6.4M wide and 5M projection. I have managed to source a maple dancefloor from the 1930's which is T&G 2 1/4" wide by 2 foot long by 3/4" thick. I have enough to cover the extension but at the same time i am replacing the flooring in my family room and kitchen(the extension links the three rooms together in a U shape with the bathroom in the centre of the U. I am going to lay the extension floor following the length of the extension and then complete the family room and kitchen with the flooring running at 90 degrees to the extension(hope this makes sense). Does anyone see there being a problem with laying the floor in this way? I have a couple of samples of the flooring and sanded them down and gave them a couple of coats of varnish just to see and the result is stunning. My worry is that i will have problems sourcing the same size and grain pattern of flooring to complete the kitchen and family room, anyone know of a company that supplies reclaimed floors and has a decent reputation(i read that more recent maple floors do not have the same grain pattern as the trees are felled much younger than in the 30's). I know this seems a bit obsessive but i have been blown away by how this flooring looks! Last question, when i did my living room floor(4" boards) a number of years ago i sealed them with Junkers floor lacquer, it has stood the test of time very well but i am wondering if there is a better product on the market now?
