Using a #4 sand will work well as it has a good
cutting profile for removing paint. Walnut shell can
also be used however it will be much more time consuming. A mixture of sand and walnut shell can be
made and for best results you might want to test each product separate and then try different mixtures. There may be other blasting mediums available in your area at a sandblasting supplier. We have had good results with sand and with a sand and shell mixture. The hardness of the wood also has an effect on the outcome.

Hi,
We're renovating an old log house, the logs have been painted and the owner wants them sandblasted. I believe there's another medium (cocoa hulls??) that is better to use on soft surfaces like wood, anyone have ideas on this? Also, we need to use a low VOC finish, as the log house will be interior exposed on all sides to the new additions. We'll need to re-chink everything, but something like Permachink may be overkill, since there's no exterior exposure... all ideas welcomed! Thanks.
