Evaluation of compressive strength of cementbased skim coat utilizing limestone from Northern Mindanao, Philippines as filler material

Overview & Synopsis

Skim coating is vital in the construction sector, particularly when constructing walls and ceilings in residential and commercial structures. It is applied on rough walls following cementation as the initial layer [1]. Skim coating is primarily employed to achieve a smooth finish and serve as a foundation for paint application. A primary benefit of skim coating is its ability to decrease the paint required to attain the desired surface substantially [2]. Skim coating safeguards concrete foundations by protecting torrential rainstorms and other natural calamities, such as earthquakes, which can significantly damage structures. This protective layer, which safeguards both walls and ceilings, has been favored for its ability to extend the interval between repainting for homeowners. The typical lifespan of a skim-coated wall and ceiling varies from 20 to 30 years, contingent upon adequate maintenance over this duration. In the Philippines,
