Woodtone’s RusticSeries ColorGuard coating transforms James Hardie, Allura, and LP SmartSide substrates into convincing wood-look siding through a proprietary two-tone finish system. The factory-applied coating delivers a 30-year warranty on lap siding while eliminating the annual staining and sealing that real cedar demands.
Manufactured by Akzo Nobel in a controlled factory environment, the coating uses a two-coat acrylic latex system with oven curing that field-applied finishes can’t match. That controlled application creates consistent film thickness and enhanced grain definition — the details that make fiber cement actually look like stained cedar from the curb.
Technical Specifications and Coverage
The coating works with three substrate systems: James Hardie fiber cement, Allura fiber cement, and LP SmartSide engineered wood. Available profiles include lap siding in widths from 5.25” to 12”, plus shakes and board-and-batten panels.
| Specification | Value |
|---|---|
| Lap Siding Widths | 5.25”, 6.25”, 7.25”, 8.25”, 9.25”, 12” |
| Standard Length | 12 feet |
| Substrate Thickness | 5/16” (fiber cement) |
| Weight Range | 9.36 lbs (5.25”) to 25.2 lbs (12”) per piece |
| Panel Weights | 77 lbs (8’) to 97 lbs (10’) |
| Color Options | 18 two-tone combinations |
The warranty structure reflects real-world exposure differences: 30 years for lap siding, 20 years for panels and shakes, 15 years for ColorSelect trim. Montana’s freeze-thaw cycles matter here — the warranty specifically requires ice and snow buildup prevention measures.
Installation Requirements and Handling
Every field cut needs sealing with matching touch-up paint — skip this step and the warranty’s void. Storage matters too: pallets stay off the ground with plastic wrap protection, and crews use slip sheeting between boards during handling.
The touch-up paint can’t freeze — once it does, it’s garbage. Mix it thoroughly before application. For certain premium finishes, colored stainless steel pan-head fasteners maintain the aesthetic without rust streaks developing over time.
Contractors praise the pre-finished nature for speeding installation, though some note the strict handling requirements to maintain the surface finish. Here’s the reality: installation equals final acceptance of the product. Inspect thoroughly at delivery because post-installation claims face mixed reception from the manufacturer.
Montana Application Considerations
The oven-cured acrylic latex system handles temperature swings better than field-applied coatings. For Montana installations, that ice and snow buildup prevention requirement means proper roof overhangs and gutter systems — not optional upgrades.
The cedar wood-grain texture comes standard, with smooth textures available by special order. Against natural cedar siding, RusticSeries costs less upfront and eliminates annual maintenance while maintaining consistent color. Compared to solid-color fiber cement, the two-tone application creates visual depth that flat colors can’t achieve.
Follow the substrate manufacturer’s installation guidelines — James Hardie’s requirements differ from LP SmartSide’s, and mixing methods voids everything. The warranty demands proper installation per substrate specs, and improper job site storage kills coverage before the siding even goes on the wall.
Frequently Asked Questions
Q: What makes the ColorGuard coating different from regular painted fiber cement?
The factory application by Akzo Nobel uses a proprietary two-coat acrylic latex system with controlled oven curing. This process creates consistent coating thickness and enhanced grain definition that field painting can’t replicate. The two-tone finish technology produces a realistic cedar appearance that single-color applications miss.
Q: How much do the lap siding pieces weigh?
Weight depends on width: 5.25” pieces weigh 9.36 pounds each, while 12” pieces weigh 25.2 pounds. Panels run heavier at 77 pounds for 8-foot lengths and 97 pounds for 10-foot lengths.
Q: What voids the warranty?
Improper storage or job site handling voids coverage immediately. Not following substrate manufacturer installation guidelines kills the warranty. Failing to prevent ice and snow buildup also voids coverage. Remember that installation counts as final product acceptance.
Q: Can I use any fiber cement substrate with this coating?
No. The coating only works with James Hardie fiber cement, Allura fiber cement, and LP SmartSide engineered wood products. Each substrate has specific installation requirements that must be followed.
Q: What maintenance does the coating require?
The coating eliminates annual staining and sealing that real wood demands. Maintenance involves only soap and water cleaning as needed. Field cuts require immediate sealing with matching touch-up paint to maintain warranty coverage.
