Gap Between Stucco Wall And Concrete

The differences between stucco wall concrete wall stucco is breathable.

Gap between stucco wall and concrete.

In the course of repairs some of the caulk weatherstripping between the trim and the house came off. This first coat is known as the scratch coat this coat helps the final coat bond properly to the wall. This will hopefully be the fix that keeps that wall of the sunroom nice and dry. Allow the scratch coat to harden slightly.

The gap between the wall and the trim is fairly large at least 1 2 inch. Stucco is made of these ingredients as well plus lime. Differences b etween concrete and stucco. Concrete is made of cement water and sand.

Apply the first coat of stucco to the concrete surface. 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. 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.

In any case this is not a drainage style system. To remedy this issue i installed backer rod in the gap that i then covered with concrete crack sealant. Stucco is cement fine sand and lime mixed with water into a paste that s spread over a surface. The scratch coat should be between 1 4 and 1 2 inch thick.

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.
