Hello,
I completed a build of a Wood Fired Oven using Refractory cement, perlite and SS needles for the Dome and Fire Bricks, Refractory cement, perlite and cement patio tiles for the hearth. The oven is built on a Treated Lumber base with heavy duty castor's in case I wanted to relocate the oven. The actual oven itself is way too heavy to move and will likely stay on the base for the rest of it's existence.
I've used it many of times and it works great with one flaw. The base/hearth is compromised of 2" thick cement patio pavers, 2" of Refractory cement/perlite 10/1 volume mixture and 1 3/4" fire brick. Total is approx 5 3/4" thick base. The flaw is after a few hours of burning I noticed the treated lumber started heating up. I'm concerned over possible combustion, chemicals seeping from the wood etc. So far the wood got to about 155F but I fear as the wood dries more that number will rise.
Reason for the post: my thought process - since moving the oven off the base is not possible I wanted to figure a way to cover or insulate the wood.
I was thinking of using a fire retardant spray, covered by durock for the exposed wood underneath the ovens base.
I'm not certain if covering it and sealing it would cause more issues. (Addition heat on the wood etc.)
My goal is for safety and to ensure the integrity of the base.
Hopefully my thoughts are clear. I would really appreciate some input and direction.
Thank you in advance,
Eric
