UV Curing Test Card

UV Exposure Card for Clean Armor Confidence starts before the finish cures. The Lite n Done UV Exposure Card gives you a fast, reliable way to check whether your UV light is operating in the range recommended for curing Clean Armor. Instead of guessing if your light is strong enough, this reusable card provides a simple visual reference so you can dial in your setup with more confidence. Printed with a specially formulated UV-reactive ink, the card changes color when exposed to UV light. In just 10–20 seconds, you can compare the result to the printed scale and see whether your light is below range, in the target cure zone, or running too hot. Designed for wavelengths from 365nm to 405nm, this card helps woodworkers and finishers verify UV output without the cost or complexity of a spectrometer. It is a practical shop tool for checking light strength, adjusting distance, and reducing the risk of cure-related problems before they affect your finish. Why it matters Clean Armor’s published cure guidance calls for 1000–3000 µW/cm² for a full cure. Falling below that range can increase cure times and the risk of an under-cured finish. Running above it can raise the chance of curing too quickly and wrinkling the finish. This card helps you stay in the window that matters. Product Highlights Fast visual check of UV light intensity Designed for the curing range used with Clean Armor Reusable for repeated testing Works with UV wavelengths from 365nm to 405nm Helps reduce guesswork before finishing How to Use Place the card under your UV light at your normal working distance, expose it for 10–20 seconds, then compare the color change to the scale printed above the test area.
