I would suggest you seal the porous surface of the cement eg pva glue/sealer and then use thin layer of washing up liquid.

Smooth the surface so the pop does not sink deeply into the texture. Make a cement grout for the outer layer. Or use nothing but fine sand in your concrete extremley well smoothed.
