How long should you shake the SP-207 can after the ball rattles?

Shaking the SP-207 can for 10 seconds after the ball inside begins to rattle is essential for ensuring that the contents are properly mixed. This duration allows the components within the can to combine effectively, leading to better performance and adherence when the product is applied. Adequate shaking ensures that the propellant and the materials in the can are thoroughly blended, which is crucial for achieving the intended results during use.

Shorter shaking times may not provide enough mixing, potentially resulting in uneven application or reduced effectiveness. On the other hand, over-shaking, such as for 30 seconds, does not significantly enhance the mixture beyond what is achieved in 10 seconds and could lead to unnecessary wear on the can or depletion of propellant. Thus, 10 seconds strikes the right balance for optimal results.
