i guess the answer is nobody knows...but i will say i dont think its a good idea...good luck

Angel,

I'm not sure about the mushrooming effect unless it is a very dark damp room. ( just kidding)

The problem I see with this technique is getting the urethane to stick to the masonite. It is such a slick smooth surface.

I would use a flooring adhesive instead of liquid nails in any case. I have not seen this successfully done.

Just dropped in to give a quick update in case anyone else is interested in this method of flooring. I couldn't find much info on this or anyone who had done it, so now that I have first hand experience I thought I would say it was fast,easy & for an inexpensive floor it looks absolutely fabulous. It glued down nicely and the varathane didn't caused any problems. The only advice I would give is don't use a roller but apply the varathane with a paint pad. It does look like polished concrete and I have had nothing but compliments on it. I don't know how durable it is going to be, only time will tell but for now I am enjoying it and have no regrets. My next project is going to be concrete counter tops, as soon as I find some info on that.

I wish you'd publish an update on your floor after five years. Pictures too maybe?

I'm thinking of using masonite in my kitchen and can't find any info on the Web.

Or contact me directly at spellinspector@gmail.com or info@my-green-home-project.com
