Expert Answer

To clean a concrete mixer, if there's only a slight residue of cement, you can add more water and use a brush to clean it. However, if there's dried-up, hardened concrete inside, break it up first, then clean it with water and a steel brush.

Question

How long do I need to wait to add layers of concrete when sculpting?

Community Answer

What's worked best for me is to add layers while the first layer is still curing or semi-moist.

Question

How do you keep the concrete from going through the wire form?

Community Answer

You have to make sure you don't add too much water. Concrete is "sticky," so as long as you don't add too much, it stays in a modeling clay type consistency.

Question

Can I paint a concrete statue if it is semi-dry or still wet?

Community Answer

You can paint at any stage after the concrete forms. Concrete is porous so if you paint while it is drying you may have to give it a second coat.

Question

After years of being exposed to the Florida weather, my cast of 3 Horses has fine cracks in it. How do I seal it to either fill the cracks or to stop them from getting bigger?

Community Answer

Look for an exterior sparkle to fill in the cracks. After you've done the fill, paint the sculpture. Then seal it using art resin.
