I'm laying a new solid oak floor in the lounge over the existing 20mm Victorian pine floorboards. The new oak is thinner than normal at 14mm. I'm planning to put hardboard down first then 6mm fibreboard from Wickes then nail the oak at an angle through the tongue. I'll probably try to hire one of those special floor nailers but I don't know yet whether it will work because the oak is thinner than standard.
The question is how many nails to use? What's the normal spacing - every
6 inches, every foot, every 2 feet or what?Kit Jackson
