VASA® Primer Multi 500 is a new high-permeability material composed of polymer emulsion and multi-functional additives. With the advantage of good sealing, high permeability, being able to improve the interface strength and so on, it is suitable for interface treatment of XPS board, interface treatment before self-leveling mortar construction, interfacial treatment of concrete and mortar base, etc. It can also be used to enhance the bonding of tile adhesive as a tile adhesive companion.
Environmental friendly, non-toxic and pollution free
High content of effective ingredients, large brushing area
Excellent permeability, sealing and consolidating performance
Significantly improving the strength of substrate interface
Improving the bonding strength of mortar and various substrates.
Applications
Interface treatment of exterior insulation materials, such as XPS board,rock wool board.
Sealing treatment of the substrate before the construction of self-leveling mortar.
Glue processing of the interface of concrete,aerated concrete,plastering layer andbrick masonry wall.
Waterproof construction on the loose lime-sand wall, and interface enhancing treatment before tiling.
Improvement of the bonding strength of tile adhesive as atileadhesivecompanion.

Construction Techniques
As a interface agent: First clean up the loose materials on the surface of the substrate. Then do the interface processing. VASA PMC-500 is ready to use without been diluted. Brush it on the substrate surface using a roller. For non-absorbent substrate such as extruded polystyrene board, one layer is enough. But for high absorbent substrate, 1 to 3 layers are needed according to the actual need. Next step can proceed after drying.
As a mixing tile adhesive companion: First, add PMC-500 multi-functional base treating agent to the mixing bucket. And then slowly add the tile adhesive, in the mean while stirring with a mechanical stirrer until a uniform lump-free tile adhesive is obtained. Stand for 3 to 5 minutes. Stir it again for 15 to 30 seconds. Then it is ready to use. The mixed tile adhesive needs to be used within 2 hours.
Announcements
