Gap Between Stucco Wall And Concrete

In the course of repairs some of the caulk weatherstripping between the trim and the house came off.

Gap between stucco wall and concrete.

Apply the first coat of stucco to the concrete surface. 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. To remedy this issue i installed backer rod in the gap that i then covered with concrete crack sealant. The scratch coat should be between 1 4 and 1 2 inch thick.

I have a stucco sided house that i am repairing repainting. A stucco wall is decorative but stucco itself has no strength and cannot support any weight. The gap in question was previously filled with either fiberboard or concrete crack sealant but enough of it has deteriorated to conceivably allow moisture in. This will hopefully be the fix that keeps that wall of the sunroom nice and dry.

In any case this is not a drainage style system. This first coat is known as the scratch coat this coat helps the final coat bond properly to the wall. The differences between stucco wall concrete wall stucco is breathable. Stucco is cement fine sand and lime mixed with water into a paste that s spread over a surface.

Concrete is made of cement water and sand. Use the flat finishing trowel to spread the stucco evenly across the surface. This prevents water from moving up and into the gaps between the sill and the cement wall it sits upon. Allow the scratch coat to harden slightly.

Stucco is made of these ingredients as well plus lime.
