Gap between stucco wall and concrete.

One big difference between the se two home exteriors is that when dry stucco is breathable it has tiny pores that allow water to evaporate from behind it so that moisture doesn t build up and cause rot. Concrete is made of cement water and sand. This prevents water from moving up and into the gaps between the sill and the cement wall it sits upon. A stucco wall is decorative but stucco itself has no strength and cannot support any weight.

This first coat is known as the scratch coat this coat helps the final coat bond properly to the wall. Use the flat finishing trowel to spread the stucco evenly across the surface.

I have a stucco sided house that i am repairing repainting. In the course of repairs some of the caulk weatherstripping between the trim and the house came off. To remedy this issue i installed backer rod in the gap that i then covered with concrete crack sealant. In any case this is not a drainage style system.

The scratch coat should be between 1 4 and 1 2 inch thick. Stucco is cement fine sand and lime mixed with water into a paste that s spread over a surface. Differences b etween concrete and stucco. Allow the scratch coat to harden slightly.

But you should not in any event seal off the gap behind the stucco as moisture will go through the surface and trapping it will only lead to more decay further up into the wall cavity.
