Hi!
I have cast a concrete countertop for my outdoor kitchen and am relatively satisfied with the result, but I had some difficulty vibrating the slab properly when we cast it, which has resulted in many small air bubbles (pores) in the slab. Now I'm wondering what the best way to get rid of these is? I've read a bit that you can try sifting concrete powder and mixing it with water ("concreteslurry"), but I find the instructions I've found a bit unclear. Has anyone done this with good results? Or should I just leave it as it is?
