May i please get some advice from the guru's out there.
PLanning to use pine 90/35 as battens to level the concrete and install Blackbutt T&G (85/19) using 38mm nails.
The slab will have a layer of epoxy based sealer and then plastic sheet as damp proof.
Reason for using pine is i need to pack 30 to 50 mm in some spaces and hardwood battens are more expensive then the timber itself.
How much trouble am i going to get into by using pine?
Thanks
