Got this planed piece of oak to make a mantlepiece 140cm x 16cm x 16cm...its very heavy i guess as is not dried out...not sure of how it was processed as i bought it online...would appreciate any advice on how to best go about treating it, and then securing on wall...the chimney breast its going on has been constructed with hollow blocks and then a layer of cement (house is in Italy)...the breast is then going to be tiled all over...not sure if better to add mantlepiece and then tile around it or put on after tiling. Also whats best way to secure it to wall?
