Painted the board with exterior paint, masked both sides, and used a design purchased from Etsy for an SD engrave. Tried spraying an exterior paint before unmasking … but, the masking was bubbling up.
Ended up using some acrylic paint for the letters … and it took four coats. Removed the masking and touched up the teal from where the bubbling up caused paint to bleed under. Then had to touch up the white again … and then the teal a bit again. Whew!
Wasn’t sure if cleaning with alcohol first would cause the masking to bubble up or disintegrate … but, do know that I wouldn’t want to make another with this same method. Very happy with the final product … just a little more work than planned.
