Interior vs Exterior Paint – What's the Difference?

Walking the paint aisle, the cans look almost identical. The chemistry inside is not.

Different Binders

Exterior paints use flexible binders so they can expand and contract through Calgary's huge temperature swings. Interior binders are rigid and would crack outside.

Different Additives

Exterior products contain UV inhibitors, mildewcides and fade-resistant pigments. Interior paints prioritise low odour, washability and easy touch-up.

Why It Matters

Using interior paint outside fails fast. Using exterior paint inside off-gasses more, smells longer and is overkill on cost. The right paint for the right surface is part of every quote we send.
