finishing a fireplace mantel

Posted by poorowner (My Page) on

I have a mantel surround and shelf in oak that I need to finish, I plan to use a stain and then floor grade polyurethane (Minwax duralseal) Then I remember seeing "check local fire codes" before fininshing and installing the product.
I wanted to know if the poly will work and to code? The wood shouldn't be getting that hot.

My fireplace is wood burning and it has a brass surrounds with rows of tiny square holes horizontally. Is it OK to position the horizontal wood piece directly above the square holes? Picture coming soon.

I also wanted to know if I should glue the ornament on before staining and sealing, or finish them individually I imagine glue will not work well after poly has been applied to the bonding surface

Thanks in advance

You really should check with local codes on this.The combustable materials have to be a set distance away from the heat source.For sure better safe that sorry.Besides you want to able to sleep at night and not worry about a fire. Hope this helps. John

I picked out the product formby's tung oil finish however they told me they do not recommend for the application, the maximum temperature is only 120F, while I am not attemping to roast my wood at all, I want to know the tempeature limits of polyurethane? Some are meant for outdoor and marine applications so the tempature limit should be higher.
