Belfast R&D Lab — Autoclaved Aerated Concrete (AAC) blocks have revolutionized building construction due to their light weight and high thermal insulation. However, AAC blocks display a dangerous physical characteristic: high capillary suction. When tilers apply wet cement mortar or plaster directly to raw AAC blocks, the block rapidly sucks all water out of the mix.
Flash-Drying Prevention & Penetration Mechanics
The Danger of Flash-Drying: Dry-mix cement mortar requires water for structural hydration. If the AAC block dehydrates the mortar within minutes, the cement cannot crystallize properly. The mortar turns into a powdery, brittle layer, destroying the bond and causing plaster cracking and tiling collapse.
The EuroFix Deep Primer solution: Developed under the supervision of Dr. Sarah Jenkins, EuroFix Deep Primer features ultra-small **acrylic copolymer nanoparticles (size 0.05 microns)**. These nanostructured polymers penetrate deep into the microscopic pores of the AAC block, forming a flexible, semi-permeable film. This acrylic barrier controls capillary water suction, reducing blocks water absorption by 85% while allowing the mortar to hydrate slowly, securing maximum tensile bond strength.
Applying deep-penetrating primers prior to plastering or tiling on lightweight blocks ensures structural longevity and prevents micro-cracks in modern high-performance walls.
