  1. Elastomeric paint is uniquely designed to cover and bridge small cracks due to its flexible and stretchable nature. However, when it comes to wide cracks, typically defined as more than 1/16 of an inch, elastomeric paint may not provide adequate coverage on its own. Wide cracks can indicate underlying structural issues that need to be addressed before applying any type of paint, including elastomeric.

    In order to effectively cover wide cracks with elastomeric paint, it is recommended to first repair and seal the cracks using a suitable crack filler or patching compound. This step is crucial to prevent water infiltration and further structural damage. Once the cracks have been properly repaired, the surface can then be coated with elastomeric paint to provide a durable and waterproof finish.

    It is important to note that elastomeric paint is not a substitute for proper surface preparation and crack repair. It is a versatile and effective coating for enhancing the weather resistance and durability of exterior surfaces, but it should be used in conjunction with appropriate repair strategies for wide cracks.

    In conclusion, while elastomeric paint can help cover and seal small cracks, it is not a standalone solution for wide cracks. Proper crack repair and surface preparation are essential steps to ensure the effectiveness of elastomeric paint in covering wide cracks and providing long-lasting protection for exterior surfaces.
