Incredible product. We used this PVA before applying our final render, and the adhesion is top-notch. It completely sealed the porous substrate and stopped the render from drying out too fast. Highly recommended for commercial jobs.

This PVA additive is a game changer for our plastering projects. It significantly improved the workability of the mortar and we haven't seen a single shrinkage crack. Will definitely be ordering more.
