Bonding Primer Paint and Sealer for All Surfaces (Indoor and Outdoors)
Four2Four Premium is an adherence bridge for paint. It ensures bonding of mineral paint to all types of surfaces such as ceramic tiles, phenolic panels, polyurethane paint, plasticised panels and most common surfaces. Suitable for indoors and outdoors applications this is a truly impressive bonding primer paint.
Graphenstone Four2Four is also an antioxidant paint for metal surfaces to keep new metal surfaces rust and corrosion free.
This bonding primer paint can also be applied as a sealant to MDF boards and to block stains coming through wood and interior walls. Note that this whitish primer does not hide stains, but helps block them from coming through the finishing top coat.
Note: This Primer/Sealer is not breathable.

Primer application for all substrates
See the Four2Four Technical Data Sheet for full details, however in brief:
- Ensure the substrate is dry, clean and sound. If the substrate is dusty, or has any grease, dirt or other impurities we recommend to thoroughly clean before applying the Four2Four.
- Mix the primer to an even consistency before applying.
- Sand between coats if a smooth final finish is required.
- If the primer is not covered with the finishing coat within 7 days it is recommended to sand softly to enhance the top coat adhesion.
How to prime bathroom and kitchen tiles for painting
- Apply 1 or 2 coats depending on the absorption of the surface (sanding between layers if a smooth finish is required).
How to prime metal for painting
- On metal surfaces with corrosion or oxidation, clean the surface and apply a passivating agent before applying Four2Four.
- For sound surfaces, sand softly to improve adhesion.
- Apply 1 or 2 coats depending on the absorption of the surface.
How to prime mdf for painting
- Apply 2 coats sanding in between layers.
How to seal wood before painting
- Sand wood (along the grain).
- Clean thoroughly removing all resins or resin secretion on the surface.
- Smooth up sharp edges.
- Apply 1 or 2 coats depending on the absorption of the surface (sanding between layers if a smooth finish is required).
How to seal stains before painting
- Apply 1 coat on the affected surface to detect the stain.
- Apply a second coat for more unmanageable spots.
- Please note that the product does not hide stains, the full opacity is achieved with the finishing paint.
