Introduction: Why Thinning Paints Is Essential in Warhammer
If you're new to Warhammer painting, learning how to thin your paints is one of the most important skills you can develop. It’s a simple step, but it makes a huge difference in how your miniatures look.
Unthinned paint can obscure fine details, leave brush marks, and create a rough finish. Properly thinned paint, on the other hand, flows smoothly and produces clean, professional-looking results.
