In this Test Tuesday, we are testing Polycrylic Spray. I am using Minwax brand water based polycrylic in semi-gloss. I used masking tape to block off a small section on the top of each sample for comparison and applied 2 coats of finish.
The polycrylic applied well to all the samples. Most importantly it did not damage any of the foam, including the No Paper sample. The finish did make the paper easier to remove on the Readi-Board, Adams Premium and Readi-Grid samples.
I was unable to scratch off the finish with my fingernail on the Readi-Erase sample (using a hobby knife blade did remove the finish). On the Readi Water Resistant sample, however, I was able to scratch the finish from the surface.
