E-Flex is a non-slump, rubber modified, off white cement-based tile adhesive with specially formulated PFR technology designed to give superior shear strength. E-Flex accommodates shrinkage movement associated with early age concrete and screeds. It can be used over concrete that is at least 7 days old and screeds and renders after 16 hours. It is flexible enough to withstand crack openings of up to 0.9mm.
