Synthetic resin-based water-dispersion primer with very low volatile organic compound (VOC) • s an anchoring coat for gypsum-based sprayable A plasters. • Before installing ceramic tiles with cementitious adhesives on: – gypsum plasters and sprayed gypsum; – pre-cast gypsum panels; – fibrous-gypsum panels; – anhydrite screeds. • o improve the adhesion of smoothing compounds T on cementitious or anhydrite and gypsum-based surfaces. • Treating gypsum walls, chipboard, cement fibre boards, foamed concrete, renders etc. prior to papering or painting. • o provide uniform absorption in cementitious T or gypsum surfaces. TECHNICAL CHARACTERISTICS 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. WHERE TO USE • or treating gypsum surfaces prior to installing F ceramic tiles. 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. • gypsum plasters prior to smoothing with On cementitious products. • anhydrite surfaces prior to applying On cement-based products. 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. • cementitious renders prior to smoothing On with gypsum-based products. 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. • gypsum walls as a fixative for wallpaper On adhesives. When used before applying sprayable plasters, Primer G prevents over-rapid absorption of water

TECHNICAL DATA (typical values) PRODUCT IDENTITY Consistency: Colour: light blue Density (g/cm³): EC1 Plus - very low emission Use as a primer for gypsum plasters APPLICATION DATA (at +23°C - 50% R.H.) Application temperature range: Drying time before the application of the levelling compounds or adhesive: - concrete: - gypsum: 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. Checking...

c) s a primer before applying selfA levelling compounds and thixotropic smoothing compounds from the MAPEI range on: • ementitious substrates: dilute c Primer G 1:1 with water; • ypsum-based substrate: use Primer G g neat. d) s a primer for wallpaper adhesives. A Dilute Primer G 1:3 with water. e) s a primer between smoothing layers. A Dilute Primer G 1:1 with water. Cleaning Tools and containers should be washed at once with clean water. Any remaining residues once dry have to be removed mechanically or with Pulicol 2000. CONSUMPTION The consumption of Primer G depends on the porosity and...
