What Is Pigment Volume Concentration in Paints?

Pigment Volume Concentration (PVC) is a technical measure of the ratio of pigment to binder (the resin component that holds pigment together and to the surface) in a paint's formulation — it's not something most consumers check directly, but it's the underlying factor behind several practical paint characteristics people do care about.

1. What PVC actually measures

PVC is expressed as a percentage representing how much of a paint's solid content, by volume, is pigment versus binder — a higher PVC means more pigment relative to binder, and a lower PVC means more binder relative to pigment.

2. How PVC relates to sheen

Generally, paints with a higher PVC tend to have a flatter, lower-gloss appearance, since more pigment relative to binder creates a rougher microscopic surface that scatters light rather than reflecting it directly — lower-PVC paints, with relatively more binder, tend to cure to a smoother, glossier surface that reflects light more directly.

3. How PVC relates to durability and washability

A lower PVC (more binder relative to pigment) generally produces a more durable, washable paint film, since the binder is what provides flexibility and resistance to wear — this is part of why higher-sheen paints (typically lower PVC) tend to be more washable and durable than flatter, higher-PVC paints.

4. The critical PVC concept

There's a specific PVC threshold (called the critical PVC) above which a paint film becomes more porous and less durable, since there's no longer enough binder to fully encapsulate all the pigment particles — paints formulated below this critical threshold generally perform better in terms of durability and resistance to moisture and staining.

5. Why this matters practically, even without checking the exact number

Understanding that sheen, durability, and hiding power are all connected through a paint's underlying pigment-to-binder ratio helps explain why, for instance, a flat paint (generally higher PVC) hides surface imperfections well but isn't as washable as a satin or semi-gloss paint (generally lower PVC) — this is a useful mental model even without needing to look up the exact percentage for a specific product.

6. PVC isn't something most people need to actively research when buying paint

For most home painting decisions, choosing based on the practical characteristics that matter (sheen, washability, hiding power, as covered throughout this site) gives the same practical result as understanding the underlying PVC chemistry — PVC is genuinely useful background knowledge for understanding why paints behave differently, more than it is a number to actively shop by.
