I want to make some cutting boards but due to the shape, timber is not
suitable as crossgrain protusions are likely to get knocked off. And
its not really possible to overcome this in one piece construction.




My prototype in MDF looks real good but its not waterproof.


So there are 2 questions,


Can I impregnate MDF with something to make it dishwasher proof?


Is there an alternative material?


I considered Corian but its a closed market product in Australia. If
you can get it it costs an arm and a leg.
