Penetrating Protection. Not Just Color.
Colorado's UV index, freeze-thaw cycles, and wind-driven moisture destroy untreated or poorly stained fences faster than almost anywhere in the country. Solid stains peel. Clear sealers wear off in one season. Penetrating semi-transparent stains — applied to properly prepared wood — last 3–5 years and protect the wood from the inside out.
Keystone Painting uses penetrating oil-based and water-based stains from premium manufacturers, applied after proper cleaning, sanding, and wood brightening. We do not brush stain over dirty, weathered wood and call it done.
Every fence project begins with a condition assessment — existing coating type, wood species, weathering, and moisture content all affect product selection and prep requirements.
Preparation: Power washing removes dirt, mildew, and failing stain. Wood brightener restores the wood's natural pH and opens the grain to accept stain. Sanding addresses rough surfaces and gray weathered wood.
Stain Application: We use penetrating semi-transparent or semi-solid stains that absorb into the wood rather than forming a film on top. Film-forming stains peel. Penetrating stains do not.
Product Selection: Stain type, sheen level, and UV protection are selected based on wood species, sun exposure, and existing finish.
why choose us
Most homeowners try to stain their own fence at least once. They buy a semi-transparent from the hardware store, roll it on, and two years later it looks worse than before — because the wood was not clean, the grain was not open, or the product was a film-former instead of a penetrating stain.
We eliminate that outcome. We prep the wood correctly, select the right product for the wood species and condition, and apply it in the right weather window. Staining in direct midday sun or when rain is forecast within 48 hours ruins the result. We schedule around both.
Our work comes with a workmanship guarantee. If the stain fails early due to our application, we come back and address it.
what to expect
Fence staining projects in Northern Colorado typically take 1–2 days, depending on fence length and prep condition.
Prep Phase: Power washing to remove dirt, mildew, and failing stain. Application of wood brightener on weathered or gray wood. Allow to dry completely — typically 24–48 hours before stain application.
Stain Application: First coat of penetrating stain applied by brush, roller, or airless sprayer depending on fence profile. Second coat applied wet-on-wet on new or bare wood, or after dry time on previously stained surfaces.
Cure & Ready to Use: Most penetrating stains are dry to touch within 2–4 hours and fully cured within 24–48 hours. We advise keeping pets and sprinklers off the fence during cure time.
