Ready Seal Exterior Stain & Sealer for Wood Fences
The most forgiving way to coat a big fence: an oil-based all-in-one stain and sealer you can spray on in one liberal coat with no back-brushing, no lap marks, and no primer, and it penetrates so pickets never crack or peel. Because fence boards are vertical and shed water, recoats stretch to about every 2-3 years. The trade-offs are a two-week color cure, a limited pre-tinted range, and less UV defense than an opaque stain.
| opacity | Semi-transparent |
|---|---|
| base | Oil-based (all-in-one stain and sealer) |
| coats | 1 coat applied liberally |
| coverage | 100-125 sq ft per gallon on smooth wood; less on rough-sawn fence pickets |
| dryTime | 48-72 hours to cure |
| cleanup | Mineral spirits |
| reapply | About every 2-3 years on a vertical fence |
| note | Reaches true color in about 14 days; spray-and-go, no thinning or primer |
DEFY Extreme Semi-Transparent Stain for Fences
A water-based semi-transparent fence stain whose zinc nano-particle pigment delivers the strongest UV and graying protection of the stains here, with low odor and soap-and-water cleanup on cedar, redwood, pine, and pressure-treated pickets. The cost is effort and yield: it needs two wet-on-wet coats, covers only about 100-150 sq ft per gallon, and depends on a proper cleaner-and-brightener prep to adhere and last.
| opacity | Semi-transparent |
|---|---|
| base | Water-based |
| coats | 2 coats wet-on-wet |
| coverage | 100-150 sq ft per gallon (two coats) |
| dryTime | 2-4 hours between coats |
| cleanup | Soap and water |
| technology | Zinc nano-particle UV protection |
| reapply | About every 2-3 years on vertical fences |
| appTemp | 45-95 F |
Our verdict
This is the core fence-stain decision. Ready Seal (oil) is the easier job by far: it sprays on in one liberal coat with no lap marks or back-brushing, penetrates so it never peels, and forgives a beginner on a long fence run — but it cures slowly over about two weeks and needs mineral-spirit cleanup. DEFY Extreme (water-based) asks more of you, with two wet-on-wet coats and careful cleaner-and-brightener prep, but rewards it with the strongest UV and graying protection here plus low odor and soap-and-water cleanup. Choose Ready Seal when you want a fast, foolproof coat on a big fence; choose DEFY Extreme when the sun-baked side of your fence needs maximum long-term color retention and you don't mind the extra coat.
