But despite the many positive feedbacks of mastic sealants, there are still some drawbacks to this material. For instance; though it stays quite flexible, it should not be applied to joints that will be frequently moved. The mastic coating will normally stay put through some amount of pressure, but it is not meant for intense joint movement. Thick applications are also preferred for mastic sealants, such as in areas with large cracks and gaps, rather than in thinner areas.

One more important thing to remember, mastic sealants usually lasts for around five years, so it should be checked from time to time to ensure that it is most effective.
