possible to apply powder coating on cement/concrete material?

[shammypenny2]

I want to know if it is possible to apply powder coating on cement/concrete material. I have tried powder coating on some of the cement products, but because of the porosity of cement, heated gas are released to the surface creating "bubbles" on the coating during the heating process.
Is there any ways to solve that problem?
Or is there other coating method that can be used on cement products beside hand paint?
thank you.

Well, you can try to block those pores doing some kind of sui generis "sealing"??

Just wild-guessing
