I am umming and ahhing about putting tongue and grooved oak flooring in my dining room "real oak, not being a great laminate fan and all" However, I am pondering on the fixing method and would appreciate some direction, the problem is that the finsihed floor is screed. I cannot see a way that I will be able to stop the floor from moving despite having the intention of glueing each tongue and groove together. In my minds eye "because the room is 30 square metres" I can see the floor being bouncy in places, once in place. Frankly I want it to go down and stay down, any suggestions would be marvellous, thank you.
