PRIMER G

Synthetic resin based primer in water dispersion. Applications: Treating gypsum or anhydrite surfaces prior to installing ceramic tiles and stone material with cementitious adhesives or levelling. The surfaces to be treated must be clean and porous. Dilute Primer G with water from 1:1 to 1:3 to protect old floors before levelling, to fix the residual dusting and to provide even absorption of substrates prior to levelling or laying. Apply on perfectly dry gypsum or anhydrite surfaces (residual moisture content less than 0.5%). Technical data: Minimum drying time: 2 hours. Application: brush or by spray. EMICODE: EC1 - extremely low emission level. Storage: 12 months. Protect from frost. Consumption 0.1-0.2 kg/m2 depending on use. Packaging 25-10-5 kg drums and 12x1 kg packs.

Uses & Advantages

Primary Uses

  • Preparing gypsum surfaces for ceramic tile installation
  • Anchoring coat for gypsum-based sprayable plasters
  • Improving adhesion of smoothing compounds on cementitious or gypsum-based surfaces
  • Providing uniform absorption on cementitious or gypsum surfaces

Key Advantages

  • Enhances adhesion of smoothing compounds, paints, and adhesives
  • Prevents chemical reactions between sulphates and cement aluminates
  • Reduces substrate absorption, minimizing glue usage for wallpaper application
  • Prevents over-rapid water absorption, prolonging workability time and reducing shrinkage cracks
