Fire Resistant Protection for Structural Bamboo
I have a question for my research, what would be the best preservation technique to use on structural bamboo? It needs to be fire resistive too. Will a boric acid-borax solution suffice? Or would an additional clear external intumescent coating help? What do you guys think? Thanks in advance. I appreciate the information you guys put here Guadua Bamboo.

Yes boron is fire retardant but for even more protection you could use the following formula: boric acid / copper sulphate / zinc chloride / sodium dichromate : ratio 3:1:5:6 Recommended concentration is 25% for indoor and outdoor use.
