The spray paint can should say how long that will take but it s usually a couple hours.
Can you spray paint wood blinds.
I used two trestles and some leftover wood.
I let it dried a bit before closing the blinds and spraypainting again.
The spray paint also made the strings stiff so that does affect the how easily the blinds raises and lowers.
It s a little time consuming to get all the slats back in the notches and facing the same way.
The shellac spray primer will bind to bare wood or wood finished with both oil and water based coatings.
Spray each slat with the shellac spray primer until the slat is coated evenly.
In the next picture the left side has 2 coats and the right side only one.
When deciding to spray paint what you have instead of buying new you need to calculate the cost of supplies and your time as to whether that outweighs the expense of new blinds.
You just need to hang the blinds in a way to be able to open and close the blinds.
And then spray until the brown is gone.
