Need to deeply seal and weatherproof porous surfaces, prepare dense substrates for waterproofing, encapsulate friable materials, or simply achieve an attractive 'wet-look' finish? Duram Azcoseal is a solvent-based clear acrylic primer and sealer designed for these exact tasks. It provides deep penetration and cures to a tough, resilient satin finish, ensuring robust sealing and a strong foundation for subsequent coatings or as a standalone protective layer.
Duram Azcoseal was developed as a versatile, solvent-based clear acrylic primer and sealer. Its low viscosity and cross-linking technology are engineered for deep penetration into highly porous substrates. This formulation effectively seals these surfaces, establishing a strong, adhesion-promoting foundation for subsequent coatings and membranes. It also offers an attractive 'wet-look' finish, ensuring durability and preventing water ingress and material degradation from the ground up.
With a general coverage rate of 4m² per litre per coat, Azcoseal offers an economical application. It is touch dry within 1 to 2 hours and fully dry within 2 to 6 hours, allowing for rapid turnaround and an extended top-coating window. The product remains effective in a service temperature range of 10°C to 50°C, proving its resilience across typical Australian climate shifts, and can be applied in temperatures ranging from 5°C to 30°C.
Duram Azcoseal is a single-component, easy-to-apply formula, suitable for application by brush, roller, or spray. For optimal results, surfaces must be sound, dry, clean, and free from dust or loose material. Remove efflorescence and ensure the surface is dry before application. For concrete, fill any voids with Duram WB/Primeseal modified mortar and treat cracks with Duram sealant. Cleanup of tools and spills is managed with Duram Solvent before the material cures.
Duram Azcoseal consistently functions as the critical first step in many Duram waterproofing and coating systems. Applied after thorough surface preparation, it penetrates porous substrates like concrete, cement render, or fibre cement sheeting. Its role is to consolidate the surface, bed down dust, and provide a uniform, adhesion-promoting layer before the application of subsequent Duram Multithane, Duram 195, Durabit, or Azcothane membranes. This foundational step is essential for ensuring the long-term bond and performance of the entire system.
Unlike many water-based primers or surface-level sealers, Duram Azcoseal is a solvent-based acrylic formulated for deep penetration into highly porous substrates. This chemical composition allows for superior binding and sealing, offering both robust weatherproofing and a strong foundational primer for subsequent coatings, alongside an attractive 'wet-look' finish. This deeper penetration provides enhanced adhesion and long-term durability compared to surface-only applications typically found with water-based options.
Yes, Azcoseal provides an attractive 'wet-look' sealer over pavers, brick, sandstone, and masonry surfaces. Always conduct a test patch first, as solvents can dissolve entrapped salts in some pavers or terracotta tiles, which may cause discolouration.
No, Azcoseal is not a vapour barrier. Do not use it in areas with high moisture, over wet or seeping surfaces, or where there is a risk of entrapped moisture that could cause bubbling. For these situations, Duram Primeseal MC is recommended.
Azcoseal is touch dry in 1-2 hours and fully cured within 24 hours at 25°C and 50% RH. For best results when priming, apply your subsequent Duram membrane or coating as soon as Azcoseal has fully cured and all solvents have evaporated.
Avoid using Azcoseal on particle board, chip board, metal, non-porous surfaces, shiny or very smooth concrete, glazed tiles, marble, or terrazzo. For particle or chip board, Duram Primeseal MC is the correct choice.
| Application | Key benefit | Primary trades |
|---|---|---|
| Weatherproofing porous surfaces | Forms a waterproof barrier against water ingress, wind-driven rain, and salt spray, protecting brick and masonry. | Bricklayers, restorers, general builders |
| Penetrative primer for Duram membranes | Enhances adhesion and waterproofing properties of subsequent Duram waterproofing membranes (e.g., Multithane, Duram 195, Durabit, Azcothane ranges), particularly on high-density substrates like tilt-up slabs. | Waterproofers, concrete contractors |
| Encapsulating friable asbestos sheeting | Binds loose fibres, sealing the surface for safer management. | Asbestos remediation specialists |
| "Wet-look" clear sealer for decorative surfaces | Dries clear with an attractive satin finish, enhancing the appearance of pavers, brick, sandstone, and masonry. Minimises dirt pick-up. | Landscapers, renovators, domestic users |
| Concrete and dust sealer | Penetrates deep to fill pores, bed down dust, and minimise surface fragmentation, creating a tougher, resilient finish. | Concrete placers, floor preparers |
| Reactivating existing acrylic coatings | Prepares old acrylic coatings for recoating, improving inter-coat adhesion without full removal. | Painters, maintenance contractors |
Ensure substrate is clean, dry, sound, and free of contaminants. Remove efflorescence, mold, and loose material using pressure washing or mechanical means.
Apply evenly at 4 m²/L per coat. Work well into substrate to ensure penetration.
Use low-pressure spray equipment for large areas. Back-roll for even film and penetration.
Clean tools and adjacent surfaces with Duram Solvent before product cures. Wash hands with warm soapy water and a stiff-bristle brush.
Danger: Flammable liquid and vapour. May be fatal if swallowed and enters airways. Causes skin irritation. Causes serious eye irritation. Harmful if inhaled. May cause respiratory irritation, drowsiness or dizziness. May damage fertility. May damage the unborn child. Toxic to aquatic life with long lasting effects. Poisons Schedule S5.
Wear safety glasses with side shields or chemical goggles. Wear chemical-protective gloves (e.g., PVC). Wear safety footwear. Use overalls and a PVC apron. A PVC protective suit may be required for severe exposure. Ensure ready access to an eyewash unit and safety shower.
Use only in well-ventilated areas. Prevent vapour concentration in hollows and sumps. Use local exhaust ventilation or a process enclosure. Ensure ventilation equipment is explosion-resistant and spark-free.
Store in original containers in an approved flammable liquid storage area, away from incompatible materials, in a cool, dry, well-ventilated place. Keep cool and locked up. Protect containers against physical damage. Dispose of contents/container to an authorised hazardous waste collection point in accordance with local regulations.
Proper surface preparation is essential for adhesion and performance. Ensure all substrates are sound, stable, dry, and clean before application.
Includes: Concrete, Cement, Cement Render, Block & Brickwork, FC and CFC Sheeting, Blue Board, AAC (Hebel), Composite Sheeting, Plywood, Cement Pavers, Sandstone, Masonry Surfaces.
Surface prep: Ensure surfaces are free of dust, loose or friable material, efflorescence, and any contaminants. Remove efflorescence and wash the area, allowing it to dry thoroughly. Fill voids with Duram WB/Primeseal modified mortar. Grind out cracks to a 'V' shape and fill with Duram sealant.
Primer: Not required. Azcoseal is a self-priming formula for these porous substrates.
Surface prep: Surfaces must be clean, dry, and free from any contaminants. Remove loose or flaking material.
Primer: Not required. Azcoseal can reactivate existing acrylics prior to recoating.
Surface prep: Clean thoroughly. Remove mould with a chlorine solution and water blaster, then vacuum loose material. Allow to dry completely.
Primer: Not required. However, test areas are highly recommended as solvents may dissolve entrapped salts, potentially discolouring the coating or tile.
