Why MABBOND+

Turn ordinary cement mortar into a high-performance finish.

Add MABBOND+ to your normal plaster mix: no extra equipment, no special training.

  • Superior adhesion

    Polymer modification dramatically improves the bond between plaster and substrate: less delamination, fewer callbacks, stronger walls.

  • Water resistance

    Treated plaster becomes hydrophobic: water beads up and rolls off instead of soaking in, protecting the wall from moisture damage.

  • Flexibility and strength

    Improved mechanical strength and flexibility means better resistance to cracking, impact and surface wear over time.

Proven on real surfaces

Don't take our word for it. Test it.

Real sample panels, real tests: the same demonstrations we run for contractors and resellers.

  • Water beading on a MABBOND+ treated plaster test panel

    Hydrophobic test

    Water beads. Walls stay dry.

    Water dropped on a MABBOND+ plaster surface forms tight beads instead of soaking in: visible proof of the water resistance built into every mix.

  • Scratch resistance test panel on MABBOND+ enhanced plaster

    Scratch and adhesion test

    Tougher surface, stronger bond.

    Repeated scratching across the panel leaves only superficial marks: no flaking, no crumbling, no delamination. The plaster holds.
