Common Painting Mistakes
Why Flat Paint Should Never Be Used in Bathrooms
The #1 mistake we see in Houston bathrooms - and how to fix it before mold takes over.
Bottom Line
Never use flat paint in bathrooms. It absorbs moisture, grows mold, stains permanently, and peels within 1-2 years in Houston's humidity. Use semi-gloss on all bathroom surfaces.
The Problem with Flat Paint in Bathrooms
Flat (matte) paint has no sheen, which means it has a porous surface that absorbs moisture rather than repelling it. In a bathroom where humidity spikes to 80-100% during showers, flat paint becomes a sponge.
What Happens Over Time
- Month 1-3: Paint absorbs moisture from steam and splashes
- Month 3-6: Water spots appear that won't wipe off
- Month 6-12: Mold spores take root in the paint's porous surface
- Year 1-2: Paint starts peeling, especially near the shower and ceiling
Why This Is Worse in Houston
Houston averages 75% outdoor humidity year-round. Your bathroom starts at a disadvantage before you even turn on the shower. Flat paint that might survive 3-5 years in Arizona will fail within 12-18 months here.
We repaint at least 2-3 bathrooms per month where the previous painter (often a DIYer or handyman) used flat or eggshell paint. The repair always costs more than doing it right the first time.
The Right Paint for Houston Bathrooms
| Surface | Recommended Finish | Why |
|---|---|---|
| Walls | Semi-Gloss | Repels moisture, easy to wipe clean |
| Ceiling | Semi-Gloss | Steam rises - ceiling needs same protection |
| Trim/Baseboards | Semi-Gloss | Handles water splashes from floor |
| Cabinets | Semi-Gloss or Satin | Withstands daily moisture exposure |
Our Recommendation: Sherwin-Williams Duration or SuperPaint
For bathroom walls in Houston, we use Sherwin-Williams Duration or SuperPaint in semi-gloss. Both have excellent mold and mildew resistance built into the formula, not just added as an afterthought.
Combined with proper surface prep and a moisture-blocking primer, these paints will last 8-10 years in a bathroom - vs. 1-2 years for flat paint.
What If Your Bathroom Already Has Flat Paint?
If you already see water stains, peeling, or mold spots, the paint needs to be removed and the surface treated before repainting. Simply painting over the problem traps moisture and mold underneath.
Our interior painting process includes mold treatment, proper priming, and the right finish to prevent this cycle from repeating.
