Features & Benefits

• Mixed with water, Mapegrout Fast-Set becomes an easily trowellable mortar with excellent thixotropic properties enabling it to be applied up to 2-2.5 cm thick on vertical surfaces without slump
• Mapegrout Fast-Set sets in 30 minutes and can be subjected to loads a few hours after application
• Once hardened, Mapegrout Fast-Set has the following properties:
• High compressive and flexural strength
• Excellent impermeability to water and adhesion to old concrete
• Good resistance to wear
• Mapegrout Fast-Set meets the requirements defined by 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 claimed by EN 1504-3 (“Structural and non structural repair”) for structural mortars of class R3

Recommendations & Limitations

• Do not add more water to the mix after setting has begun in the attempt to make it trowellable again
• Do not add cement, lime, gypsum or admixtures to Mapegrout Fast-Set
• Do not use Mapegrout Fast-Set for restoration work to be done with plaster sprayers (use Mapegrout Thixotropic)
• Do not use Mapegrout Fast-Set for precision anchors (use Mapefill or Mapefill R)
• Do not apply Mapegrout Fast-Set to dry or dirty surfaces
• Do not leave bags of Mapegrout Fast-Set exposed to direct sun before use
• Do not apply Mapegrout Fast-Set if temperature is lower than 5°C
• Do not use Mapegrout Fast-Set if the bag has been damaged or previously opened
• After hardening, Mapegrout Fast-Set could change colour, therefore its use is not recommended when it is left as a façade finish
• No special precautions need be taken when temperature is approx. 20°C
• In warm weather do not expose material to direct sun and use cold water for preparing the mix
• In low temperatures, the water should be approx. +20°C and the material should be stored in heated areas because initial setting and curing is delayed at low temperatures
