Mapei Mapelastic Smart Waterproofing Membrane

20kg Powder and 10kg Liquid

Mapelastic Smart is used for waterproofing hydraulic projects such as channels, faces of dams, swimming pools,
basins, storage tanks, etc. and balconies and terraces. Particularly suitable for waterproofing irregular surfaces.
Mapelastic Smart is also used to protect concrete structures, renders with hairline cracks and cementitious
surfaces in general which, being subject to vibrations, may suffer from cracking.

Application Examples

• Waterproofing hydraulic channels, concrete water tanks, faces of dams and basins, including those containing potable water.
• Waterproofing bathrooms, showers, balconies, terraces, swimming pools etc. before laying ceramic tiles.
• Waterproofing plasterboard, render or cementitious surfaces, lightweight cement blocks and marine-grade plywood.
• Flexible protection layer of new concrete structures or repaired structures subject to minor deformation under load.
• Protection of cementitious renders or concrete with cracks due to shrinkage, minor movement caused by thermal gradients or dynamic stresses due to the passage of vehicles, against infiltration of water and aggressive elements from the atmosphere.
• Protection of concrete pillars and beams and road and railway viaducts repaired with products from the
  Mapegrout or Planitop ranges against the penetration of carbon dioxide.
• Protection of concrete surfaces which may come into contact with sea water, de-icing salts, such as sodium or calcium chloride, and sulphates.

Advantages

• High performance: a 2 mm thick film has a crack-bridging capacity of >2 mm.
• Excellent mechanical characteristics, especially when reinforced with Mapetex Sel or Mapenet 150
  reinforcement.

• Compatible with ceramic, mosaic and natural stone coverings using MAPEI’s line of tile adhesives.
• Approved for contact with potable water.
• Meets the requirements of AS/NZS 4020:2018, Report ID D47762.
• Meets AS/NZS 4858:2004 Class II Wet Area Membrane tested by CSIRO.
• Meets the requirements of AS 4654.1:2012, exposed, non-trafficable waterproofing membrane tested by CSIRO.
• Low VOC content of 0 g/L.
• Product certified EC1 Plus by the GEV Institute (Gemeinschaft Emissions-kontrollierte).

Technical Characteristics

Mapelastic Smart is a two-component mortar based on cementitious binders, fine-grained selected
aggregates, special admixtures and synthetic polymers in water dispersion, blended according to a formula
developed in MAPEI’s own research laboratories.
When the two components are mixed, a blend with a plastic consistency is obtained. It may be applied by brush,
by roller or by spraying with a worm screw rendering machine on both horizontal and vertical surfaces at a
thickness of approximately 2 mm. Due to the content and high quality of the synthetic resins, the hardened
layer of Mapelastic Smart remains constantly flexible under all environmental conditions.
Mapelastic Smart is waterproof and resistant to the penetration of aggressive substances which are present in
the atmosphere, such as carbon dioxide, sulphur dioxide and sulphuric anhydride, and soluble salts such as
chlorides and sulphates, which are present in seawater or in the ground.
Mapelastic Smart has excellent bonding properties on all cementitious, ceramic and marble surfaces as long as
they are sound, sufficiently clean and properly prepared.
These properties, together with its resistance to the deteriorating effect of UV rays, a characteristic of this product,
ensure that structures protected and waterproofed with Mapelastic Smart have a long service life, even if they
are located in areas with particularly rigid climatic conditions, in coastal areas with a saline-rich atmosphere or
in industrial areas where the air is particularly polluted.

Recommendations

• Do not apply Mapelastic Smart at temperatures lower than +8°C.
• Do not add cement, aggregates or water to Mapelastic Smart.
• Protect from rain and water spillages for the first 24 hours after application.
• Do not leave Mapelastic Smart exposed in swimming pools.
• Do not apply on cementitious substrates not sufficiently cured.
• During hot weather, it is advisable to keep the product out of direct sunlight before use (power and liquid).

Application

REFER TO TECHNICAL DATA SHEET PDF (See Specifications – Below)

Precautions

• No special precautions need to be taken when the temperature is around +20°C.
• During hot weather, it is advisable to keep the product out of direct sunlight before use (powder and liquid).
• After application, and in particularly dry, hot or windy weather, we recommend that the surface is protected
  from rapid evaporation with sheets.

Cleaning

Due to the high bonding strength of Mapelastic Smart, even on metals, we recommend that work tools are washed with water before the mortar sets. Once it has set, cleaning may only be carried out by mechanical means.

Consumption

Application by trowel or roller:
Approx. 1.6 kg/m² per mm of thickness.

Spray gun application:
Approx. 2.2 kg/m² per mm of thickness.

N.B.: the consumption figures indicated are for a seamless film on a flat surface and are higher if applied on uneven substrates.

Packaging

component A: 20 kg bags;
component B: 10 kg drums.

(Yield 18.75 Litres / 30 kg kit)

Storage

Mapelastic Smart component A may be stored for up to 12 months when contained in its original sealed packaging in a dry place.
Mapelastic Smart component B may be stored for up to 24 months.
Store Mapelastic Smart in a dry place and at a temperature of at least +5°C.
