Concrete Statue Molds [Where to Buy How To Make] – KRK ...
Best Concrete Mix For Molds. You want to use a ratio of 3 to 1, 3 part sand 1 part cement, ( the sand I use has pea gravel in it) and you mix this in the wheelbarrow till you can''t see the color of the sand. It should all look grey, like the cement. Then add water till you get a soupy consistency. That is how I do it. It''s been working for me.
