F4 Bonding Liquid is a water based, penetrating, bonding and stabilising liquid / sealer for interior and exterior use on powdery, friable and very porous new and weathered substrates such as lime wash, old paint, new friable or porous plaster and fillers. Once the F4 Bonding Liquid has done its job these areas can be over-coated with a range of F4 Paints’ water based decorative products.

  • The product penetrates deep into the substrate and stabilizes it.
  • Based on a resin emulsion and can therefore be diluted with water, which makes it a very cost effective product.
  • The product has a good alkaline resistance and can be used on objects where aggressive minerals are present.
  • Once sealed can be top coated with a wide range of F4 Paints’ waterbased products.
  • Excellent penetrating and binding properties.
  • Excellent adhesion
