Just remember that you need to use a relatively soft wax that will penetrate the base.
If however you want to experiment, heat up a block of hard wax and a block of soft wax. Mix'em up and you have what we call a conditioner wax. When it is applied on a base the soft penetrates deep while the hard stays closer to the surface. Apply it with an iron and put the board in the sauna.
Another thing is that when the board is out from the sauna DONT WIPE THE WAX OFF, ( I 've seen people do that). Let it cool and then scrape and brush.
