Are you tiling onto plasterboard, gypsum, or cement surfaces? Do you need to improve adhesion, reduce dust, and prevent moisture problems? Primer G is a versatile, low-VOC primer that prepares and seals porous surfaces, ensuring your tiles, flooring, or wallpaper stick securely and last longer.
Why Use Primer G?
Better Adhesion: Creates a strong bond between the substrate and tile adhesive, smoothing compound, or wallpaper paste.
Reduces Porosity: Seals dusty or highly absorbent surfaces to prevent rapid drying and improve workability.
Prevents Chemical Reactions: Stops sulphates in gypsum from reacting with cement, which can cause failure and cracking.
Low Odour & Eco-Friendly: EMICODE EC1 Plus certified with very low VOC emissions—safe for indoor use.
Easy to Apply: Ready to use—just stir and apply with a brush or roller.
Ideal For:
Priming gypsum plaster, plasterboard, and anhydrite screeds before tiling
Sealing cementitious surfaces before applying self-levelling compounds
Preparing walls before wallpapering or painting
Improving adhesion between layers of smoothing compounds
Treating chipboard, cement fibre boards, and foamed concrete
How to Apply:
Prepare the Surface: Clean, dry, and dust-free. Sand smooth/glossy surfaces if needed.
Stir Primer G: Do not shake—stir gently before use.
Dilute if Required:
For cement surfaces: Dilute 1:1 with water.
For gypsum surfaces: Use undiluted.
For wallpaper: Dilute 1:3 with water.
Apply Evenly: Use a brush or roller to apply a thin, uniform coat.
Let Dry: Allow 30–60 minutes before applying adhesive, levelling compound, or tiles.
Coverage & Packaging:
Coverage: 0.08–0.15 kg/m² depending on surface porosity
Available in: 1 kg, 5 kg, 10 kg, and 25 kg containers
Shelf Life: 12 months in original sealed packaging
