Two-component, flexible cementitious mortar for protecting large concrete structures subject to high stress
CO2 FULLY OFFSET PRODUCTS
Mapelastic Guard Zero is part of the CO2 Fully Offset in the Entire Life Cycle line of products. CO2 emissions measured throughout the life cycle of products from the Zero line in 2024 using Life Cycle Assessment (LCA) methodology, have been offset through the acquisition of certified carbon credits in support of forestry protection projects. A commitment to the planet, to people and to biodiversity. For more details on how emissions are calculated and on climate mitigation projects financed through certified carbon credits, visit the webpage zero.mapei.com.
WHERE TO USE
Protecting concrete structures against aggressive atmospheric agents.
TECHNICAL CHARACTERISTICS
Mapelastic Guard Zero is a two-component, flexible, light grey mortar made from cementitious binders, fine-grained selected aggregates, special additives and synthetic polymers in water dispersion according to a formula developed in the MAPEI Research & Development Laboratories.
When the two components are mixed together, a free-flowing mix is obtained which may be applied at thicknesses up to 2 mm, including on vertical surfaces. Thanks to its high content of quality synthetic resins, the hardened layer of Mapelastic Guard Zero maintains its flexibility under all environmental conditions, and is totally impermeable to water at pressures up to 1.5 atmospheres and the penetration of de-icing salts, sulphates, chlorides and carbon dioxide.
Mapelastic Guard Zero also has excellent adhesion on all concrete surfaces, provided that they are sound and sufficiently clean. These properties, together with its excellent resistance to U.V. rays, ensures that structures protected with Mapelastic Guard Zero are durable, even when located in areas with particularly cold climatic conditions, in coastal areas with a saline-rich atmosphere or in industrial areas where the air is highly polluted.
Mapelastic Guard Zero complies with the principles defined in EN 1504-9 ("Products and systems for the protection and repair of concrete structures - Definitions, requirements, quality control and evaluation of conformity - General principles for the use of products and systems”) and the minimum requirements of EN 1504-2 coating (C) according to principles PI, MC and IR (“Surface protection systems for concrete”).
