Hanza Seal

Alkalinity & Salt Barrier: Exceptional capability to buffer structural cement alkalinity and trap salts, preventing paint discoloration or localized staining.

Suction Control & Cost Efficiency: Thoroughly seals porous rendering, preventing the substrate from absorbing moisture from putties and paints, minimizing total coating costs.

Superb Mechanical Anchoring: Functions as a highly robust bonding bridge that securely anchors heavy wall putties onto dense concrete surfaces.

Eco-Friendly Formulation (Low VOC): Water-based compound free from hazardous organic solvents or pungent fumes, ideal for both indoor and outdoor applications.

Substrate Stress Elasticity: Offers excellent structural elongation properties to counteract hairline cracks caused by concrete drying shrinkage.

Primary priming undercoat applied over newly rendered internal and external structural masonry walls and ceilings.

Pre-treatment and priming of smooth fair-face concrete and internal gypsum board panels prior to putty application.

Protective moisture-barrier undercoat for cementitious surfaces exposed to relative humidity before decorative latex coating application.

Binding and consolidating loose, chalky surfaces during historical structural renovations before re-painting phases.

Substrate Preparation: Ensure the substrate is fully cured (minimum 28 days for new plaster), clean, dry, and free from loose dust, form-release oils, or structural contaminants.

Dilution: Dilute Hanza Seal with clean municipal water at a ratio of 10% to 25% depending on substrate porosity parameters. Stir thoroughly until a homogeneous matrix is achieved.

Application: Apply evenly using standard rollers, nylon brushes, or airless spray machinery to guarantee an uninterrupted protective film.

Curing & Overcoating: Allow the applied primer film to cure for 2 to 4 hours. Once completely dry, application of standard CMB wall putties can proceed immediately.
