Product Overview

Premium
Performance

WeeFixX – Block Joining Mortar, also referred to as thin Bed AAC block jointing Adhesive, is a high strength adhesive for quick and firm laying of AAC blocks with thin joints. It is a factory mixed mortar made up of cement, graded sand and blended with polymers to impart high strength and water retention properties even when in thickness of 2–3 mm layer.

Designed for use with AAC (Autoclaved Aerated Concrete) blocks, cellular concrete, fly ash bricks, and hollow concrete blocks, this product reduces material consumption, saves construction time, and delivers a cleaner and more precise finish than traditional cement mortar.
