RealTrim Plus™ solves the moisture trap problem that kills fascia boards in Montana. This Western SPF trim combines 6-sided flood coating with mold-resistant additives, offering contractors a pre-primed solution that eliminates sub-fascia requirements while providing 15-year substrate warranty protection against rot.
The product targets residential contractors who understand that what goes behind the paint matters as much as what shows. Factory-applied Hybrid Alkyd Emulsion (HAE) primer on all six sides beats field-applied primers hands down — especially when spring snowmelt keeps everything wet for weeks.
6-Sided Protection and Material Specs
The flood-coating process covers every surface with ultra-low VOC primer, including end grain where moisture typically penetrates first. Borax additives in the coating system provide enhanced mold resistance — critical when Montana’s 94% January humidity (Libby) meets spring thaw cycles.
Hand-selected, tight-grained, kiln-dried Western SPF substrate forms the core. Kiln-drying matters here. Montana’s low humidity and temperature swings punish wet lumber with checking, warping, and dimensional instability.

Three face texture options — Combed Face, Smooth Face, Resawn Face — provide reversible installation flexibility. Less waste when one damaged face doesn’t ruin the whole board.
Installation Requirements and Warranty Compliance
Getting the warranty means following the rules. Hot-dip galvanized nails only — 6d or 8d with 3/16 inch heads and minimum 1-1/4 inch penetration into framing. No staples or T-nails. Period. Those fasteners void everything.
Two coats of approved exterior acrylic latex paint required within 60 days of installation. Not a suggestion — it’s warranty-voiding if ignored. Minimum 2.5 mils dry film thickness protects the substrate investment.
Maintain 1/2 inch air space from masonry, concrete, or roof surfaces. Montana’s freeze-thaw cycles turn trapped moisture into rot factories. That half-inch gap saves callbacks.
Seal all field-cut ends and machined surfaces with high-quality exterior primer before installation. The factory coating can’t protect what contractors cut on-site.
Cost and Time Advantages
Eliminating separate sub-fascia changes the math on every job. One product instead of two. One installation pass instead of layering components. No specialty tools required — standard saws, standard fasteners, standard techniques.
Lengths up to 24 feet for 2-inch nominal reduce joints on Montana’s sprawling ranch homes. Fewer joints mean fewer failure points and cleaner sight lines.
The 25-year topcoat warranty with ColorGuard system extends protection when contractors use the complete factory-finished option. 15-year substrate warranty against rot backs the core material regardless of finish choice.
The Bottom Line
RealTrim Plus™ earns consideration for Montana contractors who’ve replaced too many rotted fascia boards. The 6-sided flood coating addresses moisture from every angle. The mold-resistant additives handle what coating alone can’t stop. The warranty numbers — 15 years on substrate, up to 25 on finish — reflect genuine confidence in the protection system.
Compared to field-primed cedar, it offers more consistent grade selection and complete pre-priming. Against fiber cement, it cuts with standard tools and creates no silica dust. Versus composite trim, it provides real wood workability.
Not perfect for every application. Uses void warranty when installed as batten strips or handrails. Proposition 65 warning for wood dust and chemicals applies like all wood products.
But for exterior fascia, rake boards, and trim where moisture resistance matters more than bottom-line material cost? RealTrim Plus™ delivers measurable advantages over lumber yard SPF that’ll rot in five years when the caulk fails.
Frequently Asked Questions
What makes the 6-sided coating different from regular primed trim?
Flood-coating applies primer to all six surfaces including end grain, compared to face-only or partial priming typical of field-applied treatments. The factory-controlled HAE primer application ensures consistent coverage that field brushing can’t match.
Can I use any type of fastener for installation?
No. Only hot-dip galvanized nails with 3/16 inch heads qualify. Staples and T-nails are explicitly prohibited. Using non-approved fasteners voids all warranty coverage.
How soon after installation do I need to paint?
Within 60 days. Two coats of approved exterior acrylic latex paint in satin, semi-gloss, or full-gloss finish are required. The paint must achieve minimum 2.5 mils dry film thickness for warranty compliance.
What happens if I need to cut or rout the boards on site?
All field-cut ends and machined surfaces must be sealed with high-quality exterior primer before installation. The factory coating only protects original surfaces — any cuts expose raw wood that needs immediate protection.
Does the warranty cover all exterior applications?
No. Misuse as batten strips or handrails specifically voids the warranty. The product is designed for exterior fascia boards, trim, window and door casing, garage door liner, column wraps, and similar applications.
