Bricks, Masonry, Asphalt and Concrete - Can't get any help in the siding section (Stucco over concrete block)

One of my children has a long ranch style home built of concrete block that's been painted. What are her options with stucco? Cost is a big issue. Would the structure have to be sandblasted? What is the least costly method of stuccoing?

Several time painted 50 year old concrete block house, finish in very good shape. Desire to cover with stucco, Is that possible if so what are best methods. Likely cost per sq, foot (NC)?

Thatnk in advance, Greensboro_man

You can cover concrete block with stucco.

For a traditional stucco application, you would first attach (nail) wire mesh to the house. After that, apply the 2 or 3 coat system to the mesh/house. The mesh eliminates any large cracks and provides a positive attachment.

Talk to a local contractor for prices. He can give you a price that reflects the local labor rates and your house (height, corners, windows, etc.).

Most likely the paint is not adhering properly, now, thus the option of stucco. It would be best to blast the old paint off, get back down to a good substrate and start over with the stucco. I would even apply something like Damtite or UGL to the surface to help prevent permeation of water to the finish.

There are also stucco panels available.

MODERATOR'S NOTE: Thread in Siding Merged with this one.

Traditional stucco will not be the cheapest way to cover the house (I may be wrong). A local contractor would be your first step to look at options.

If you were further north, synthetic stucco over rigid insulation could be a option since you do not have wood frame construction (often not permitted over wood). You probably don't need extra insulation.

Some thoughts on stucco panels depending on their composition -

Many stucco panels may look like stucco, but they are not compatible your heavy, rigid structure that moderates temperature and moisture.

Most panels are OK for lightweight, flexible structures like wood frame.

Unless they are cement-based with no wood, they will not have a long life unless you spend a fortune to protect the back side and interior.

The only realistic option is as Concretemasonry said: lath it.
