refractory cement

[Reynaldo Garza]

I just applied a can of rutland brand refractory cement over the other layer on my forge. I followed directions to apply let it dry and add heat gradually in which I did. I noticed it started bubbling where I applied the cement. I guess where I live it is humid so, it didn't dry between the walls. Will this ugliness have any effect on heat coming from burners?. Or should I scrape the bubbles and start over and let it dry overnight to allow dryness to affect between the walls?. This is all new to me, comments and advise please. Rey

On my forge I used Satanite as a coating,so I don't know about the rutland but you should have let it air dry for 12 hours or so before starting heating,then fire up the forge for a couple of minits let it cool fire it up again a little hotter, and about the third heating take it on up to forging temp.
Hope this helps
