Anyone tried this yet? It's MDF, but not as we know it. There's some chem= ical jiggery pokery done at the cellular level, such that the binder resin = now also waterproofs the individual fibres. The result is weatherproof MDF= .
It looks like MDF. Same hardness, density and abrasion to tools.
It's weatherproof like a plastic. Decades of outdoor use expected.
Downside, not surprisingly, is the cost. Something like =A3180 for a 12mm s= heet.
