Product Details

PRODUCT DESCRIPTION

MAXSEAL® SUPER is a high-performance cement-based waterproof coating formulated with special cements, carefully graded aggregates, and advanced organic and inorganic additives.

Its unique crystallisation and osmotic technology penetrates concrete capillaries, sealing pores and micro-cracks to create a monolithic waterproof barrier. Once applied, the product crystallises within the structure, blocking water ingress while allowing vapour diffusion.

Ideal for use on both fresh or cured concrete, pre-cast elements, cement renders, bricks, and masonry. Suitable for positive and negative water pressure, it ensures long-term protection against moisture, salt attack, and corrosion.

⚙️ Key Features

  • Crystalline Waterproof Coating
  • Osmotic Concrete Sealing
  • Internal Crack Repair
  • Vapour Diffusion Safe
  • Non-Toxic Formula
  • Salt-Resistant Shield
  • Paintable Finish Surface
  • Durable, Long-Lasting Protection

🧰 Application Fields

  • Waterproofing basements, foundations, retaining walls, and below-grade concrete.
  • Sealing water tanks, tunnels, shafts, and treatment plants.

  • Protecting dams, reservoirs, and concrete blocks from moisture ingress.

  • Suitable for drinking water structures and confined waterproofing spaces.

  • Effective for positive and negative hydrostatic pressure areas.

🧾 Advantages


  • Non-toxic — safe for potable water and indoor spaces.

  • Crystallises within concrete, sealing pores and micro-cracks (up to 0.4 mm).
  • 100 % waterproof — ideal for immersion or high-pressure applications.
  • Excellent saltwater and chemical resistance for marine and underground works.
  • Easy application by brush, broom, or spray on damp surfaces.
  • Allows vapour diffusion — prevents trapped moisture.
  • Long-lasting, paintable finish — no maintenance required.

⚒️ Coverage & Application

  • Mix with 6–7 L water per 25 kg bag.
  • Apply 2 coats (cross direction), total consumption ≈ 2–2.5 kg/m².
  • Can be dusted or brushed on fresh or cured concrete.
