Mapei Elastorapid 2 part high-performance tile adhesive
Mapei Elastoreapid is atwo components, highly deformable, high performance non-slip cement-based adhesive with extended open time for ceramic tiles and natural stone.
Highly deformable, high performance cementitious adhesive, fast-setting and hydrating, with extended open time and no vertical slip for ceramic tiles and stone materials.
Classification
Elastorapid is an improved (2), fast-setting (F) cementitious (C) adhesive, slip-resistant (T) and with exteneded open time (E), of class C2FTE.
Where to Use
Bonding to internal and external walls and floors of all types and sizes of ceramic tiles (single fired, double fired, porcelain, clinker, terracotta etc), natural stone (marble, granite etc) and artificial materials which are slightly sensitive to humidity (class B MAPEI dimensional stability standard) which require the use of a fast-drying adhesive.
Example Applications
- Layng ceramic and stone floor coverings which are subject to intense traffic.
- Quick repair operations where the floor needs to be put into service immediately (public buildings, motorway service areas, supermarkets, airports, pedestrian areas), even during hot weather. Compared with other fast-setting adhesives, the longer pot-life of Elastorapid makes it more easy to apply even during hot weather.
- Laying tiles on deformable substrates: marine plywood, wooden agglomerates (if sufficiently stable to water), old wooden floors etc.
- Quick laying or repair of tiled finishes in places such as swimming places, refigeration cells, industrial plants (breweries, wine cellars, dairies etc).
- Laying even large-sized ceramic and stone tiles on facades, balconies, terraces, and sun-roofs and patios which are subject to direct sunlight and thermal.
- Laying tiles in areas subject to high mechanical stresses and vibration (railway underpasses, underground railway platforms, etc).
- Laying tiles on concrete substrates and pre-cast walls.
- Laying large-sized tiles on heated screeds or on top of existing floor coverings in ceramic, terazzo, marble etc.
- Laying tiles on surfaces waterproofed with Mapelastic or Mapegum WPS.
- Laying stone material which is sensitive to stains (white carrara, etc).
Technical Characteristics

Elastorapid is a two-component adhesive available in grey or white consisting of a special binder and selected silica sand (comp. A) and a synthetic latex rubber (comp. B).
When the two components are mixed together, a mortar with the following characteristics is obtained:
- low viscosity
- highly thixotropic: Elastorapid may be applied on vertical surfaces without sagging, and even large-sized, heavy tiles do not slip. Tiles may be laid starting from the top of the surface without spacers
- the pot life of the mix is particularly long compared with other fast-setting adhesives, making the laying operation easier even during the summer at high temperatures.
- good capacity for accomodating deformation of the substrate and tiles (chipboard, marine plywood, concrete, etc).
- perfect bodning to all materials normally used in building;
- thicknesses of up to 10mm without shrinkage and without reduction in thickness, until a considerably high mechanical strengh is reached
Elastorapid has high bonding strength after only 2-3 hours, and therefore, floor and wall covering may be put into service very quickly.
Grouting and Sealing
The joint sbetween the tiles may be grouted after 3 hours with a suitable MAPEI cementitious or epoxy grout, which is available in a variety of colours. Expansions joints must be sealed with a suitable MAPEI sealant.
