Do you have a glass or metal project that you’d like to paint? Maybe you have a shiny, smooth surface that you’re worried about tackling. Come see this tutorial to learn our tips and tricks for getting better adhesion on smooth surfaces!
In this tutorial company co-founder, Rosanne will paint and distress some mason jars to show how to prepare smooth surfaces like glass and metal to improve adhesion. If you'd rather watch a video, we also have a video tutorial available towards the bottom of the page!
The reason it can be difficult for paint to adhere to smooth surfaces is because they are very non-porous and there is no texture for the paint to grip onto. Follow these quick tips to make sure your paint will last for years to come!
Use a gentle, natural soap and warm water to clean your surface and remove any contaminants or oil that might prevent the paint from adhering. After you’ve washed your entire surface, it’s a good idea to use a new cloth to wipe everything down with plain water to remove any last residue.
Wait until your surface is completely dry, then use a coarse sanding block to lightly sand the entire surface of your piece. This will give your piece a bit more to grip on to and will lead to better adhesion. Make sure you use a clean cloth to wipe away any dust this creates before you move on to the next step.
We recommend choosing our All-in-One Decor Paint for tricky surfaces like glass and metal as it has even better adhesive qualities than our chalk-based paint. Remember that two thin coats of paint are always better than one! If you paint thick coats, they will take much longer to cure and they won’t adhere as well to your surface, so start with one thin coat all over your surface.
For most colors you’ll find that just one coat is sufficient, but if you’d like to add a second coat you can do so after letting the first coat dry for about 1-2 hours.
If you like the shabby chic, distressed look, you can use 120 grit sandpaper to distress the raised areas on your piece. Make sure you let the paint dry for a few days before starting this process! Gently rub any corners or accent areas that would naturally get more wear and tear with your sanding block until you’re happy with the look. Use a clean, dry cloth to wipe away any dust this creates.
For maximum durability, we recommend sealing your finish with our Tough Coat. You can learn more about how to apply Tough Coat by clicking here.
