Hanza Seal
Hanza Seal
Hanza Seal is a premium quality, water-based acrylic sealer and primer engineered from high-grade pure acrylic resins and bonding copolymers.
Technical Property | Value / Description | Engineering Benefit |
Chemical Base | Premium Pure Acrylic Emulsion | Outstanding cohesion and absolute resistance to substrate alkalinity |
Appearance | Milky white liquid (Dries to a transparent film) | Allows precise application tracking and full surface coverage check |
Specific Gravity | $1.05 \pm 0.05$ kg/liter | Optimized viscosity for deep concrete pore penetration |
Drying Time | 1 - 2 Hours (Depending on ambient temperature) | Accelerated site workflow allowing putty application on the same day |
Porosity & Coverage | High substrate coverage & Low water permeability | Maximizes substrate protection while reducing topcoat absorption |

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.
