Extra Bond is a water based polymer emulsion. When added to milk paint, it gives greater adhesion to non-porous surfaces or previously finished pieces. Its environmentally safe, non toxic and VOC free. Clean up is easy since its a water based product – just simple soap and water will do.
Basically – it is recommended that if you are going to be using milk paint over a piece that has been previously painted, has an old finish on it (polyurethane, shellac) or will be painting a non porous surface such as glass, metal, laminate – this is the product you use to give the paint better adhesion and keep the paint from peeling off.
HOW TO USE IT
Using the Extra Bond is really simple because there are no extra steps involved!
To use, you mix your milk paint according to the directions (add water and powder together) and then add your Extra Bond and mix. Its important to mix up your milk paint 1st and then add the bond. If you add the bond directly to your powder and then add water, it will be a clumpy mess.
When i know that i will be adding the bond, i do make my milk paint mixture slightly thicker than i would normally. The bond wont thin out your paint too much, but it may just a little. If it still too thick after adding the bond, you are fine to add more water. The consistency should still be the same as if just using milk paint alone would.
