Spray each slat with the shellac spray primer until the slat is coated evenly.
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.
In the next picture the left side has 2 coats and the right side only one.
The spray paint can should say how long that will take but it s usually a couple hours.
And then spray until the brown is gone.
Use what you have on hand.
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.
Attach blinds to window brackets.
The spray paint also made the strings stiff so that does affect the how easily the blinds raises and lowers.
