How Long Does Exterior Paint Last in Texas? (2026) Best Paint for the Heat

How long does exterior paint last on each siding type?

On James Hardie fiber cement, Sherwin-Williams Duration lasts 10 to 15 years in Central Texas sun, and Sherwin-Williams puts exterior paint in general at 7 to 10 years, depending on climate, surface and paint quality.

James Hardie's factory ColorPlus finish holds its appearance for 12 to 18 years. On any surface, how long paint lasts comes down to prep, the paint itself, color and how much sun the wall takes.

How often should you paint a house exterior in Texas?

Plan on repainting a Texas home every 7 to 10 years, the range Sherwin-Williams gives for exterior paint in general, and every 10 to 15 years for James Hardie fiber cement painted with Sherwin-Williams Duration.

James Hardie's factory ColorPlus finish holds its appearance for 12 to 18 years. South and west walls take the direct afternoon sun and usually need attention 2 to 3 years before north and east walls, so check those first.

What is the best exterior paint for Texas heat?

In our opinion, the best exterior paint for Texas heat is [Sherwin-Williams Duration Exterior Acrylic Latex](https://www.sherwin-williams.com/homeowners/products/duration-exterior-acrylic-latex), and it is the paint we use. Sherwin-Williams backs Duration with a lifetime limited warranty against peeling and blistering, which covers replacement paint, not labor.

We recommend acrylic latex formulations exclusively for Central Texas homes. Oil-based paints crack and peel faster in heat, while 100% acrylic latex expands and contracts with temperature changes and keeps its grip through Central Texas thermal cycling.

Color matters as much as the can. Darker colors absorb more heat and fade faster in direct Texas sun, so a dark body color means repainting sooner.

Why do south and west walls fail first?

South and west walls fail first because they take the direct afternoon sun: on a south or west wall in July, surface temperatures regularly hit 130 to 160°F.

UV breaks paint down in a set order: chalking first (a powdery residue when you rub the wall), then fading, then cracking, then peeling. That progression shows up on sun-exposed walls first, with south and west elevations degrading 2 to 3 years ahead of north and east walls.

Heat also causes blistering when paint goes on too hot. Heat-related failure shows as small blisters concentrated on sun-exposed walls, usually 6 to 18 months after painting, and often on the south and west walls first.

When should you not paint a house exterior in Central Texas?

Do not paint when the wall surface is above 90°F, when the air is below 50°F, when the surface is wet from rain or morning dew, or when rain is due before the paint has set.

In Central Texas you can paint in any season; what matters is the conditions on the day. Above 90°F at the surface, paint dries too fast, the top layer skins over, and the film can blister and peel within 1 to 2 years, so on hot days a wall is best painted while it is in shade.
