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.
Can you spray paint wood blinds.
I let it dried a bit before closing the blinds and spraypainting again.
In the next picture the left side has 2 coats and the right side only one.
Spray each slat with the shellac spray primer until the slat is coated evenly.
And then spray until the brown is gone.
Use what you have on hand.
The spray paint also made the strings stiff so that does affect the how easily the blinds raises and lowers.
Laying the blinds down on the table make it easier because there s less tension on the strings.
I used two trestles and some leftover wood.
The spray paint can should say how long that will take but it s usually a couple hours.
Attach blinds to window brackets.
