- New to moderately weathered wood fences
- One coat water based coating
- Big box availability with custom tints
- High coverage per gallon
Behr's water-based semi-transparent stain and sealer is the convenient big-box pick: one coat, up to 400 sq ft per gallon, hundreds of custom tints, and easy soap-and-water cleanup for a fast weekend fence. Be realistic about its advertised 8-year life; sun-facing fence sides commonly fade and need attention around year 3-4, it can flake over old or damp wood, and thirsty rough pickets cut its coverage and may need a second coat.
Pros
- Goes on in a single water-based coat and covers up to 400 sq ft per gallon, cheap and fast on long fences
- Sold at every Home Depot with hundreds of custom tints, so matching or buying more is trivial
- Low odor and soap-and-water cleanup make it beginner-friendly for a weekend fence project
Cons
- Real-world durability trails the 8-year claim; sun-exposed fence faces often fade and need work by year 3-4
- As a semi-transparent film it can flake at spots if applied over an old coating or damp wood
- Coverage and color depth suffer badly on rough, thirsty pickets, sometimes forcing a second coat

Frequently Asked Questions
- How long does BEHR semi-transparent stain actually last on a fence?
- Behr rates it up to 8 years, but real-world results on sun-exposed faces typically need attention by year 3-4. Plan maintenance around exposure rather than the label number.
- Will one gallon really cover 400 sq ft?
- On smooth, less porous wood, yes. Coverage and color depth suffer badly on rough-sawn pickets, which sometimes forces a second coat and effectively halves the yield.
- Can you apply it over an old coating?
- It is risky — as a semi-transparent film it can flake in spots over an old coating or damp wood. Strip or clean back to sound, dry wood first for a result that lasts.
