The Liquid Rubber Concrete Foundation and Basement Sealant is a versatile option for various sealing needs, including foundations, basements, and more. Its high flexibility and durability are standout features, as the sealant membrane can stretch significantly without cracking, making it reliable for long-term use.

The water-based formula is environmentally friendly, containing no VOCs or harmful odors, making it safe for indoor and outdoor use without special breathing apparatus. However, one drawback is that the product remains tacky, which means it's not suitable for surfaces that will be walked on. This limitation could be a concern for those needing a sealer for floors or other walking surfaces.

It is also important to note that the product only accepts full kit returns, which may be inconvenient if not all of the product is used. This sealer is ideal for users needing a flexible, durable, and environmentally friendly option for non-walking surfaces.
