Bloomington homes face a battle every year: summer humidity, winter freeze-thaw cycles, intense sun, and sudden storms. Exterior paint is your home's armor. But not all paint is created equal — and how it's applied matters just as much. This guide explains how quality paints and professional techniques resist fading, moisture, and cracking, ultimately protecting your home's structure.
Moisture seeps into wood, causing rot and blistering. Paint must breathe while blocking liquid water.
vapor permeabilityFreeze-thaw cycles expand and contract materials. Inflexible paint cracks and peels.
elasticity neededIce dams, snow melt against foundations, and freeze stress. Paint must adhere despite moisture behind it.
adhesion criticalIndiana sun fades colors and degrades binders. Quality pigments and UV blockers resist fading.
fade resistanceOur location in southern Indiana means hot, humid summers and cold, snowy winters. That's a punishing combo for exterior paint. Local pros like exterier house painting specialists understand these conditions intimately. As one Bloomington company notes: "We use premium paints designed for durability, color retention, and long-term performance... finishes that hold up beautifully against daily use, weather exposure, and time."
| component | role | weather defense | what to look for |
|---|---|---|---|
| 🧴 binders | hold pigment together, form film | flexibility (acrylic) resists cracking | 100% acrylic for exteriors |
| 🎨 pigments | provide color, hide surface | quality pigments resist UV fading | iron oxides, titanium dioxide |
| 💧 additives | mildewcides, thickeners, etc. | prevent mold, improve application | microbicidal, water repellent |
| 🧪 solvents/water | carry paint to surface | water-based (latex) dries, allows breathability | low VOC, water cleanup |
Water can enter through cracks, behind siding, or from ground splash. Once trapped, it causes peeling, rot, and mold. Quality exterior paints are breathable — they let water vapor escape while blocking liquid. This is why 100% acrylic latex is preferred: it remains flexible, adheres well, and resists moisture. Proper surface prep (cleaning, patching, priming) is just as critical — without it, even the best paint will fail.
Indiana sun may not be Arizona, but it still degrades paint. UV breaks down binders, causing chalking and fading. Premium paints use light-stable pigments (like iron oxides) and UV absorbers. Light colors reflect more UV and last longer, while deep hues may need extra coats or specialty formulations. A professional painter can recommend colors that balance aesthetics and durability.
Even the best paint fails if applied poorly. Professionals follow strict guidelines:
