  • Waterproofing and coating of drinking water tanks.
  • Waterproofing of swimming pools.
  • Waterproofing of tunnels, galleries, basements and elevator pits subject to high water pressure.
  • Waterproofing and protection of concrete in water treatment plants, settling tanks, etc.
  • Coating for waterproofing of dams and retaining walls.
  • Waterproof coating for façades and wall faces, concrete blocks and prefabricated panels.
  • Restoration and waterproofing of channels.
  • Waterproofing and decorative finish for silos and cooling towers in thermal power plants


  • Excellent waterproofing properties.
  • Withstands both positive and negative hydrostatic pressures which allows Maxseal to be used for internal & external waterproofing .
  • Allows application on wet substrates.
  • The coating allows the substrate to breath it does 
not form a water vapour barrier.
  • Final layer of MAXSEAL® can be used as a decorative finish, saving further painting.
  • Easy to use, no maintenance required.
  • Resistant to aggressive environments such as seaside and zones with atmospheric pollution.
  • It resists weathering and freeze/thaw cycles longer lasting than paints and other coatings.
  • Very good adhesion as it forms part of substrate. It fills and seals all pores and becomes part of the 
  • Suitable for use in contact with drinking water.
  • Once MAXSEAL® is cured, it can be rendered or painted.
  • Environmentally friendly.

Application Instructions

Surface preparation

Drizoro Maxseal can only be applied to a medium to high porosity surface as this product requires porosity for a total bond.

Repair and fill all suspect areas, the entire surface to be coated should be thoroughly saturated with clean water. Allow excess water to drain before applying Maxseal®. Do not leave free-standing or pooled water on the surface.

The surface to be coated must be solid and clean, free of all traces of paint, efflorescence, loose particles, grease, form- stripping oils, dust, gypsum plaster, etc.

It is the responsibility of the applicator to determine whether a structure contains any form of efflorescence prior to application.

Any traces of efflorescence in negative waterproofing must be removed.

Please refer to efflorescence specification.


Add three parts of Drizoro Maxseal to one part of clean water in a clean container.

Mixing is best done by mechanical means only, such as a slow speed mixing drill (400-600 rpm).

Small quantities may be mixed manually with a trowel.

When mixing manually care must be taken to ensure product is mixed thoroughly.

Mix until a thick creamy paste free of lumps is achieved (mixing time about 1 to 2 minutes).

Allow the mixture to rest for 5 minutes and then remix briefly prior to application.

A 25 kg bag requires approx. 7 to 8 ltrs of water approx , optimum, temperature range from 15 °C to 28°C.


In order to fill and cover all pores and voids, Drizoro Maxseal should be applied using a fibre brush or a nylon fibre broom, such as Maxbrush or Maxbroom respectively.

Apply the product on the surface in a thick layer, making in a homogeneous and continuous coating. Do not spread the product as if it were paint.

Once Maxseal® has been spread, it must not be brushed again. A second layer must be applied in the perpendicular direction of the first one, with a waiting-time of 12-16 hours between layers.

Second layer may be texture rolled or trowel finished to achieve decorative finishes.

Maxseal can be applied using spray equipment.

In order to ensure complete and uniform coverage and proper sealing of all voids etc, the sprayed area should be brushed or broomed.

If Drizoro Maxseal is going to be rendered over, on vertical surfaces, it is advisable to apply the second layer horizontally.

For pipelines, the second layer should be applied in the direction of the water flow.

Application conditions

The optimum temperature range for application is from 15 oC to 20 oC. Do not apply Maxseal if rain is expected within 4-6 hours after the application.

In winter, do not apply Drizoro Maxseal below 5 oC or if such temperatures are expected within 24 hours after application. Do not apply the coating on frozen or frosted surfaces.

For applications during hot temperatures and windy conditions, i.e. summer time, the surface must be wet with plenty of water. Once Maxseal has been applied , if product appears to be drying out too quickly spray the surface slightly with a fine mist of water.


Allow Maxseal to cure for at least 7 days at 20 C and 50% of relative humidity prior to immersion in water.

Lower temperatures and higher relative humidity increase the curing time.


Before product hardens, all tools and equipment must be cleaned immediately with water. Cured material can only be cleaned by mechanical means.


  • Do not apply in excess of 2 layers.
  • Do not apply to bitumen or polyurethanes.
  • Do not place plastic or core flute protection boards against treated surfaces prior to back filling.
  • Drainage cell and aggregate can be placed..

During curing, water vapour may condense on the Surface in poorly ventilated areas.
Allow surface to cure for 3 days prior to back filling and 7 days prior to filling structure with water.
