Hi, i have read many of your posts and have learnt a lot, thanks for that, i want to run my installation by you to make sure all is good. Its a lounge/ dinning room 25m square, i will be laying 18mm thick, 125mm wide, random length solid oak tong and groove boards over the original floor boards. The flooring will be laid in the opposite direction to the floorboards. The width of the room in approx 3m. Flooring is fairly level (+- 2mm maybe) and dry. I'm going to float the floor gluing all edges of the tongs and grooves, with a 10-12mm expansion gap around the perimeter of the room. Skirting will then be refitted to cover the gap. I have always used fiber board underlay when i have installed laminate in the past, would this be suitable for solid flooring also? Do you recommend strapping the floor every so often to pull the boards together? Much appreciated
