Mapei Primer G

    MAP10049
    MAP10049

    Synthetic resin-based water-dispersion primer with very low volatile organic compound (VOC) for treating gypsum surfaces prior to installing ceramic tiles, as an anchoring coat for gypsum-based sprayable plasters, and to improve the adhesion of smoothing compounds on cementitious or anhydrite and gypsum-based surfaces. Some application examples:

    • Preparing cement-based surfaces prior to smoothing with self-levelling or thixotropic smoothing compounds
    • Between layers of smoothing compounds once the first coat is perfectly dry
    • On gypsum plasters prior to smoothing with cementitious products
    • On anhydrite surfaces prior to applying cement-based products
    • On cementitious renders prior to smoothing with gypsum-based products
    • On gypsum walls as a fixative for wallpaper adhesives
    • Before installing ceramic tiles with cementitious adhesives on:
      • Gypsum plasters and sprayed gypsum, Pre-cast gypsum panels
      • Fibrous-gypsum panels, Anhydrite screeds
    • Treating gypsum walls, chipboard, cement fibre boards, foamed concrete, renders etc. prior to papering or painting
    • For professional use only.

    Description

    Primer G is a synthetic resin-based primer which, once applied to any surface, dries to form a flexible, compact, shiny coating which consolidates the surface, where needed. Primer G also improves the adhesion of smoothing compounds, paint, adhesive for wall paper, adhesive for tiles and mortar for renders.

    Features & Benefits


    • The film of Primer G on the surface of gypsum or cement, prevents any chemical reaction between sulphates and the cement alluminates of gypsum which, in the presence of moisture, leads to the formation of the salt “ettringite’’ which is the cause of the separation of the two elements
    • The use of Primer G when papering allows to reduce the substrate’s absorption and, as a result, the amount of glue used, thus making the wallpaper removal much easier
    • When used before applying sprayable plasters, Primer G prevents over-rapid absorption of water by the substrate, prolongs workability time and helps prevent shrinkage cracks
    • When used before the application of self-levelling compounds, Primer G reduces the formation of air bubbles and helps prevent over-rapid drying making self-levelling easier
    • Primer G is not flammable and can therefore also be used in closed, unventilated environments without any precautions having to be taken



    Recommendations & Limitations


    • Primer G does not waterproof gypsum substrates even though it considerably reduces their porosity and absorption
    • Do not apply onto magnesium substrates
    • Primer G is not recommended for external applications or where rising damp is present
    • Do not apply Primer G in such a quantity that it forms a surface film; dilute with water as appropriate for the absorption of the substrate
