I got on the forum this morning to see if any one has used any good fire and mold retardant products and I was shocked to read about the post on 8/3 by R.C. and the loss of that beautiful home you built. Very sorry to hear that. You've got a good attitude though.
I am building a post and beam barn that I am converting into our home. After framing with all of the timbers and looking at the amount of exposed wood the subject of fire protection is in my face every day. I have also have had some mold growth on some of the lumber.
I have been researching spray on non toxic fire retardant/ mold prevention products and I was wondering if anyone in the forum can reccomend any products especially ones that will still allow us to stain or finish the wood.

Thanks RL

yes, consider the sprinkler.
bleach kills mold, sunlight helps also.

I used Timbor on the inside of my wall cavities and sills when I gutted my 100yr old house. It claims to deter insects and mold. I paid $75 for a 5 gal bucket of powder (to be mixed with water and sprayed on) 4 years ago. The house never had insulation in the walls and I didn't replace the original cedar siding. If any moisture got into in the past, it would have dried pretty quickly. I figured the Timbor would help if a little bit of moisture got into the wall after it was full of insulation. It can't be used on exposed wood work though.
