Bonding Agent allows Milk Paint to adhere to metal, glass and painted, varnished or lacquered surfaces. It is a water-based concentrated acrylic emulsion that can be mixed with milk paint or used as a primer. This product contains no VOC’s and is almost odorless.
It is the exact same formula as Fusion’s Ultra Grip, so the two products are interchangeable for the different paints and their respective purposes. So if we are ever out of stock of one, you can always substitute it for the other.
How to Use Miss Mustard Seed’s Bonding Agent
- sand the surface to remove any flaking or chipping paint if there is any, or sand to key the surface on any glossy/shiny pieces.
- mix your chosen colour of Miss Mustard Seed’s Milk Paint as normal at a ratio of 1:1.
- add a generous squeeze of Bonding Agent to your mixed paint and stir. The bottle instructions say to use a ratio of 1 part bonding to 1 part mixed paint, however, I find this is excessive and tends to thin out the paint and change the consistency and the colour too much.
- you will only need to add Bonding Agent in to the first coat of paint. Any subsequent coats don’t require any as the first coat has already done its job of adhering to the smooth surface.
Alternatively, you may choose to add a very thin coat of Bonding Agent to the surface of your piece BEFORE painting normally with Miss Mustard Seed’s mixed Milk Paint. This is similar to the way you would use it for any other water based paints, to create a better grip for paint to adhere to.
