Flowcrete Flowflex is a single-component, non-sag, elastic joint sealant based on hybrid polymers. Once fully cured, it remains permanently elastic while offering excellent mechanical strength.
It is ideal for sealing joints and gaps that require durability and flexibility. The sealant is available in two colour options: black and concrete grey, making it suitable for different applications. Flowflex provides reliable performance for both construction and repair projects.
