Test Tuesday: Lacquer Thinner

In this edition of Test Tuesday, we will be testing lacquer thinner. I am using Sunnyside brand lacquer thinner, applied to each of the samples using a small paint brush.

Readi-Board samples

Adams Premium samples

The lacquer thinner penetrated the paper facers and damaged the foam beneath. This was true for all of the samples except the Readi-Erase. The dry erase facer was resilient enough to allow the solvent to evaporate before reaching the foam. However, I still do not recommend using lacquer thinner on any foam board products.

No Paper, Readi-Erase, Readi Water Resistant and Readi-Grid samples

We have a video that demonstrates the destructive nature of lacquer thinner on the foam.
