How to spray paint glass and plastic without the spraypaint cracking

I have been spray painting for a long long time.  I think that there isn’t any thing in this world that cant be saved by spray paint!  Except wall to wall carpet and we will not discuss that experiment ever again. he he

Back in the day I loved the crackled look and I knew excatly how to create the look with my cans of spray paint.  However that look is not in at the moment and I want a clean fresh glossy look when I spray paint.

Glass is tricky because it doesn’t absorb the paint, the paint must sit on top of the glass and is easily scratched off.  So after your project is finished I suggest you coat your creations with a few coats of spray polyurethane. These vases above I did a few years ago and I wanted to use them at a wedding for flowers but the cost was way too high  so instead we thrifted glass vases and sprayed them all white.  Well some were modpodged but that’s another post.

Ok lets get started.
1.  This is the number one rule light even coats. and when I say light I mean light!!!  Do not coat your glass with a heavy thick coat of paint this will bring on the crackling, when you spray the next layer.

2. To coat a glass vase completely I used about 4 light coats of Rust-oleum spray-paint.  Starting spraying to the side of the  project and then sweeping over the project and off the other side.  It might take several swipes to cover the vase with the first coat.

3. I only wait a few min for the paint to dry before starting with my second coat.  I continue this process until I get the coverage I need.  usually four coats of paint.

4.  if your paint isn’t drying in 3-5 min or so then you have sprayed it on too thick and you will run the risk of cracking.  If its too cold or too hot cracking can occur as well.

5. If your project does start to crackle wait for it to dry and lightly sand the offending area with very find sandpaper or steel wool and respray that area.
