Product description
Comtech Bond PVA is a specialized construction chemical formulated to improve the mechanical properties of cement-based mixtures. As a polyvinyl acetate (PVA) emulsion, it acts as a powerful bonding agent and plasticizer, ensuring superior adhesion between new plaster layers and existing substrates such as concrete, brick, or masonry.
This additive significantly enhances the workability of mortar, allowing for smoother application and reduced cracking. By improving the cohesion of the mix, it results in a denser, more durable finish that resists water penetration and mechanical stress. It is an essential component for professional plasterers and contractors seeking to deliver high-quality, long-lasting surface finishes.
- Enhances adhesion between new plaster and old surfaces
- Improves workability and consistency of mortar
- Reduces shrinkage and cracking in finished coats
- Increases resistance to water and weathering
- Compatible with standard cement and sand mixes
