Adherence bridge for paints. Antioxidant in metals. Wood sealer & stains.

Four2Four Premium is an adherence bridge for paint. It ensures adherence of mineral paint to all types of surfaces such as tiles, phenolic panels, polyurethane paint, etc., for indoors and outdoors applications. In addition, it acts as an antioxidant in metal substrates (free of corrosion or oxidation) and as a sealant of wood, MDF boards and stains on interior walls.

It ensures the adherence of paints on all kinds of surfaces.

  • Excellent adherence bridge.
  • Antioxidant on metal surfaces.
  • Sealer on wood, MDF boards and stains.
  • Suitable for all types of surfaces.
  • Tough and long-lasting.
  • Quick drying.
  • Suitable for interiors and exteriors.
  • Especially suitable for smooth and non-porous surfaces such as ceramics, polyurethane or epoxy paints, plasticised panels, etc.
  • Suitable for metal and wooden surfaces

FOR METAL: Bonding adherence and/or metal surfaces: apply 1 or 2 coats depending on absorption or exteriors. Softly sand to improve adhesion.

FOR WOOD: Wood sealant: sand wood following the wood grain, clean thoroughly, remove all resins or resin secretion on the surface and smooth up sharp edges. Apply 1 or 2 layers depending on absorption the substrate, sanding between layers if a smooth finish is required.

FOR MDF: MDF board sealant: apply 2 coats, sanding between layers. – Stain sealant: apply a 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.

Breathability: Four2Four isn’t as breathable as the other natural paints, you generally only use it on non-porous surfaces (Metal/wood etc).
t’s important to know if breathability is required, whilst the bricks themselves aren’t likely to need it the mortar may do if that is a requirement.

Sample / Tester Pots

We offer 2 types of tester pots on most products on all pages (in the drop down box)
1) ‘Colour Tester 100ml – (Standard colour matched pot for all Graphenstone paints)’ £4.99 per tester pot. We use our premium grafclean paint to offer sample pots in all colours we offer. The colour of this tester is exactly the same as the colour in the other paint ranges, which is why we offer it as a standard tester pot (as it’s cheaper as we can use this one paint for all colours). We mix this per order.
​ 2) ‘Colour Tester 100ml – (In this specific paint to test texture or sheen)’ £7.80 per tester pot. For people who want to check the exact paint, we also offer a tester pot in the actual paint (for people who want to check texture / consistency) as the colour is exactly the same as the standard tester pot.

Large orders of big tubs will need to be sent on a pallet, so may be +1-2 working days. ECO PACKAGING: Testers use bio degradable corn starch infill packing pieces (these are only suited to testers and very light weight items though); on larger products we either use recycled/recyclable brown paper or we’re just starting to use pulped cardboard inserts for 2.5l and 5l tins - these are recycled and can either be recycled with household cardboard, composted or several people use them as firefighters!
