RealTrim Plus™ offers contractors the only 6-sided flood-coated trim that actually backs its performance claims with substance. The 15-year substrate warranty against rot paired with up to 25-year topcoat coverage when using the ColorGuard system puts real confidence behind the product. Made from hand-selected, kiln-dried Western SPF, this isn’t just another primed board — it’s engineered to survive Montana’s freeze-thaw punishment.
6-Sided Flood Coating and Material Technology
The flood-coating on all 6 sides changes the moisture game completely. Most trim products coat what you see and leave the back exposed. Water finds those unprotected surfaces. RealTrim Plus uses a Hybrid Alkyd Emulsion (HAE) primer with ultra-low VOC, developed through partnership with Sherwin Williams. The coating technology matters — Borax additives provide mold resistance where other products rely on hope.
The substrate starts with hand-selected, tight-grained Western SPF that’s kiln-dried. Not all SPF grades the same. Hand selection weeds out the twisted grain and defects that cause warping. Kiln-drying brings moisture content down to stable levels before coating — critical for dimensional stability in Montana’s low-humidity climate.
The two-step sealant technology (ISOTEK) developed with Sherwin Williams delivers industry-leading resistance to mold and mildew growth. That’s not marketing fluff when you’re dealing with spring snowmelt keeping trim wet for weeks at the ground line.
Specifications and Installation Requirements
Available in 1”, 5/4”, and 2” nominal thicknesses — actual dimensions run 0.6875” (11/16”), 1.125” (1-1/8”), and 1.4375” (1-7/16”). The range covers everything from 1x2 through 1x12, plus 2x2 through 2x12. Lengths run 8 to 20 feet, with 2-inch nominal available up to 24 feet. Those longer lengths reduce joints on Montana’s sprawling ranch homes.
| Specification | Value | Source |

| Width Range | 1x2 through 2x12 | Manufacturer |
| Standard Lengths | 8 ft to 20 ft | Manufacturer |
| Extended Length (2”) | Up to 24 ft | Manufacturer |
| Face Options | Combed, Smooth, Resawn (reversible) | Manufacturer |
Installation demands respect for the warranty terms. Use hot-dip galvanized nails — 6d or 8d with 3/16 inch heads and minimum 1-1/4 inch penetration. No staples or T-nails. The galvanizing requirement isn’t negotiable — standard nails will corrode and streak.
Seal all field-cut ends and machined surfaces with high-quality exterior primer before installation. Every cut exposes raw wood. Skip this step and you’ve created a moisture entry point that voids the warranty.
Paint within 60 days using two coats of approved exterior acrylic latex in satin, semi-gloss, or full-gloss. Minimum 2.5 mils dry film thickness. That 60-day window matters — UV degradation starts immediately on primer.
Maintain 1/2 inch air space from masonry, concrete, or roof surfaces using metal flashing or drip edges. Direct contact with masonry wicks moisture into the wood. That half-inch gap plus proper flashing keeps water moving away from the trim.
Warranty Coverage and Real-World Performance
The 15-year limited substrate warranty against rot stands out in the trim market. Most wood products hedge their bets with shorter coverage. Add the ColorGuard factory topcoat system and warranty extends to 25 years. Ground truth documentation confirms a 25-year warranty, backing the flood-coating technology with real coverage.
Warranty voids if used as batten strips or handrails. Those applications see different stress patterns than vertical trim or horizontal fascia. The product’s engineered for specific uses — respect those limits.
RealTrim Plus applications include exterior fascia boards, vertical and horizontal trim, bellyband trim, window and door casing, garage door liner (2-inch nominal), column and post wraps, rake and frieze boards, and porch or deck balusters. The 2-inch material works particularly well for garage door surrounds where beefier dimensions look proportional.
Professional contractors generally view RealTrim Plus positively, highlighting its strengths in durability and performance. The combination of proper substrate selection, comprehensive coating, and warranty backing creates a product that delivers on its promises — when installed correctly.
For Montana contractors dealing with 100+ freeze-thaw cycles annually, the kiln-dried stability and 6-sided protection address the primary failure points of standard trim. The Western SPF substrate handles temperature swings better than many alternatives. Available lengths up to 20 feet mean fewer joints to seal and maintain.
Not perfect for every application. The premium positioning means higher upfront cost than basic primed trim. Typical considerations include cost and the need for proper installation to maximize benefits. But for builders who understand that trim failure leads to expensive callbacks, RealTrim Plus delivers measurable advantages in moisture resistance and dimensional stability.
Frequently Asked Questions
Q: What’s the actual thickness of Woodtone RealTrim Plus boards compared to nominal sizes?
Woodtone RealTrim Plus 1” nominal boards measure 11/16” (0.6875”) actual, 5/4” boards measure 1-1/8” (1.125”) actual, and 2” boards measure 1-7/16” (1.4375”) actual. These dimensions are consistent across all width options from 1x2 through 2x12.
Q: What type of nails should I use for installing RealTrim Plus?
RealTrim Plus requires hot-dip galvanized nails (6d or 8d) with 3/16 inch heads and minimum 1-1/4 inch penetration into framing — staples and T-nails are specifically prohibited. Using non-galvanized fasteners will cause corrosion streaking and potentially void the warranty.
Q: How long do I have to paint RealTrim Plus after installation?
You must apply two coats of approved exterior acrylic latex paint (satin, semi-gloss, or full-gloss) within 60 days of installing RealTrim Plus, achieving a minimum 2.5 mils dry film thickness. The 60-day window is critical as UV degradation of the primer begins immediately after installation.
Q: What warranty coverage does Woodtone offer on RealTrim Plus?
Woodtone RealTrim Plus comes with a 15-year limited substrate warranty against rot, which extends to 25 years when using the factory-applied ColorGuard topcoat system. The warranty voids if the product is misused for applications like batten strips or handrails.
Q: What’s special about the coating on RealTrim Plus compared to standard primed trim?
RealTrim Plus features flood-coating on all 6 sides using a Hybrid Alkyd Emulsion (HAE) primer with Borax additives for mold resistance, developed through Woodtone’s partnership with Sherwin Williams. This complete coverage protects all surfaces including the back side, unlike standard trim that typically only coats visible faces.
Q: What lengths are available for RealTrim Plus boards?
RealTrim Plus boards come in lengths from 8 to 20 feet for most sizes, with 2-inch nominal thickness available up to 24 feet. These longer lengths reduce the number of joints needed on larger projects.
