MEGALASTIC

Bostik Megalastic is a multi-purpose liquid additive designed to upgrade the performance of cement-based tile adhesives, grouts, screeds, and other similar systems. It improves adhesion, flexibility, and water resistance in whatever it's mixed into, and it does this without costing anything in return, sustaining the same open time, pot life, and workability as the unmodified product.
It's suited to any job where a cement-based system needs to work harder, from immersed installations like pools to general outdoor exposure. It upgrades the whole Bostik rigid adhesive and grout range without making the mix sticky, even when used neat.

Why choose Megalastic?
Megalastic is built to upgrade rigid adhesives and grouts, all while maintaining the product's existing workability, so there's no trade-off for the performance gain. It also delivers a smooth trowel feel and long working times, and once cured, it's suitable for full immersion, making it the difference-maker for wet area and pool applications.

Where to use it
Megalastic is mixed into Bostik cement-based tile adhesives, grouts, screeds, mortars, and renders as a full or partial water replacement, depending on the system. See TDS for full details. 

TIP: Grouting a pool surround or another fully immersed job? Pair Megalastic with Designer Grout, mixing it at 50% strength to upgrade the grout's water resistance and flexibility, while standard indoor and outdoor tiling can rely on Designer Grout alone.
