Rowmark LaserGloss Exterior is a high-quality, two-ply acrylic engraving sheet with a high-gloss finish, specifically developed for laser engraving in outdoor applications. This material combines a premium glossy appearance with enhanced UV and weather resistance, ensuring long-lasting colour, gloss and readability when exposed to sunlight, rain and temperature fluctuations.

The specially formulated cap layer resists discolouration and degradation caused by UV radiation. The contrasting core ensures sharp, clear engraving with fine details. LaserGloss Exterior is designed for CO₂ laser engraving and delivers consistent results, even in long-term outdoor use.
