Mapei Primer G further information

Consumption: The consumption of Mapei Primer G depends on the porosity and absorption of the surface.

Normal consumption is between 0.08 and 0.15 kg/m2.

WHERE TO USE

For treating gypsum surfaces prior to installing ceramic tiles.

  • As an anchoring coat for gypsum-based sprayable plasters.
  • To improve the adhesion of smoothing compounds on cementitious or anhydrite and gypsum-based surfaces.
  • To provide uniform absorption in cementitious or gypsum 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.

MAPEI PRIMER G TECHNICAL CHARACTERISTICS

Mapei 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.

The film of Mapei 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 Mapei 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, Mapei 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, Mapei Primer G reduces the formation of air bubbles and helps prevent over-rapid drying making self-levelling easier.

Mapei Primer G is not flammable and can therefore also be used in closed, unventilated environments without any precautions having to be taken.

RECOMMENDATIONS

  • 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.

APPLICATION PROCEDURE Preparation of the substrate

The substrate must be clean, dry and free from oils, grease, residual paint and other loose material.

In each case, the manufacturer’s recommendations for gypsum-plaster must be followed, particularly as far as moisture content and level of surface finishing are concerned. Cracks in concrete surfaces must be repaired with Eporip or Epojet. Anhydrite surfaces must be sandpapered.

Application

a) As a treatment for ceramic tiles installed on gypsum.
Stir Mapei Primer G just before use, spread it uniformly on the surface with a flat brush or roller without diluting it. If the gypsum plaster surface is particularly smooth and glossy, it is recommended to abrade it beforehand. Once it has dried, install the tiles.

b) As an anchoring coat for gypsum plasters.

Dilute Mapei Primer G 1:2 with water and stir well; spread uniformly the mix on the surface with a flat brush or roller or spray pump. Apply the sprayable gypsum plaster as soon as Primer G is dry.

c) As a primer before applying self- levelling compounds and thixotropic smoothing compounds from the MAPEI range on:

  • cementitious substrates: dilute Mapei Primer G 1:1 with water;
  • gypsum-based substrate: use Mapei Primer G neat.

d) As a primer for wallpaper adhesives. Dilute Mapei Primer G 1:3 with water.

e) As a primer between smoothing layers. Dilute Mapei 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.

MAPEI PRIMER G STORAGE

Mapei Primer G, in its original unopened packaging, can be stored for 12 months. Protect from frost.

BTP very helpful in supplying a pallet of floor leveller. I needed it on the Saturday, but didn’t want it sitting on the driveway for several days. I called and they recommended ordering for Thursday to give a day’s grace in case of any delivery issues. In the event the pallet arrived on Thursday as requested. Reliable and good value
