The Short, Careful Answer

Do not paint Gentek Fairhaven Sound siding unless Gentek provides written approval and product-specific preparation and coating instructions for your exact siding. Gentek’s published Fairhaven Sound materials present the product as a finished, low-maintenance polypropylene cladding, but the currently published product page and warranty do not provide homeowners with a field-painting procedure.

That distinction matters. General advice about painting PVC vinyl siding, wood shakes, or fiber-cement siding should not automatically be transferred to polypropylene shakes and scallops. The Polymeric Exterior Products Association, formerly the Vinyl Siding Institute, also advises following the manufacturer’s specifications for polypropylene products.

Why Fairhaven Sound Is Different from Painted Wood

Gentek identifies Fairhaven Sound Single Select as heavy-duty polypropylene siding. Its color, cedar-inspired surface and molded profile are manufactured as part of the finished exterior product. Gentek also promotes a Color Clear Through® system intended to coordinate siding, soffit, fascia, trim and rainware colors across an exterior.

• The material is polypropylene. It should not be assumed to accept the same primers or paints as wood, aluminum, fiber cement or PVC vinyl.
• The cedar character is molded into the surface. Excessively heavy coatings could make fine grain and shadow details look less distinct.
• The original color belongs to a coordinated system. A field-selected paint may not match the sheen or undertone of the factory-finished trim, soffit and accessories.
• The panels are designed to move. Polymeric cladding expands and contracts as temperatures change. Coating behavior at panel joints, locks and concealed edges therefore requires product-specific guidance.

Painting Can Change More Than the Color

A color can look attractive on a paint chip and still produce an uneven result on installed shake siding. Fairhaven Sound relies on deep texture, individual-shake variation and shadow lines to create its cedar-like appearance. A field coating introduces several aesthetic variables.

Texture and sheen

Paint can collect differently on raised grain, recessed grooves and panel edges. Spraying, brushing and rolling may each produce a different sheen. Under low morning or evening light, these differences can become more noticeable than they appeared during application.

Joints and concealed areas

Installed panels overlap. As the cladding responds to temperature changes, a previously concealed portion may become visible. If only the exposed face was coated, small lines of the original factory color could appear at joints.

Trim coordination

Recoloring the shakes alone can disrupt an otherwise deliberate relationship among corner posts, window trim, soffit, fascia, gutters, roofing, masonry and garage doors. The result may technically be a “new color” without looking like a unified exterior design.

Start with the Reason You Want to Paint

What If the Siding Appears to Be Fading?

Do not use paint to cover suspected abnormal fading before documenting the condition. Gentek’s Fairhaven Sound warranty defines manufacturing defects and separately describes limited fade protection, including a measurable color-change threshold during the stated coverage period. Coverage, eligibility, exclusions and remedies depend on the complete warranty—not a summary of it.

1. Locate the original invoice, installation date, product name and color.
2. Photograph each elevation in consistent daylight.
3. Compare exposed siding with a protected or less-exposed location, without dismantling the wall.
4. Record whether the condition is uniform, elevation-specific or limited to certain panels.
5. Contact the supplier, installer or Gentek warranty department before cleaning aggressively, coating or replacing material.

The warranty states that Gentek or the issuing company determines whether qualifying excessive fading has occurred. It also reserves the option to repair, replace, refinish or provide another stated remedy. Homeowners should therefore allow the claim process to proceed before independently applying a coating.

Could Paint Affect the Warranty?

The safest answer is that warranty consequences must be confirmed in writing for the proposed coating and condition. The published Fairhaven Sound warranty contains exclusions, limitations and claim procedures, but it should not be paraphrased as a blanket “painting voids the entire warranty” statement unless Gentek makes that determination.

A more defensible question is: would the coating obscure the reported defect, contribute to damage, prevent inspection, or make the original finish impossible to evaluate? Ask Gentek to respond to that question before work begins, and retain the written response with the home’s exterior records.

PEPA Guidance Supports a Manufacturer-First Approach

The Polymeric Exterior Products Association describes vinyl and other polymeric siding as low-maintenance cladding that does not require routine painting. PEPA also distinguishes polypropylene siding from PVC vinyl siding and directs users to follow the siding manufacturer’s specifications.

This is an important boundary: an article or paint label saying a coating is compatible with “vinyl” is not, by itself, confirmation that it is appropriate for a specific polypropylene shake panel. Product identity and written manufacturer instructions should control the decision.

Design Alternatives to Painting the Shakes

If the real goal is a fresher exterior, the best solution may not involve coating the siding at all. From an aesthetic standpoint, consider whether one of these more controlled changes would deliver the desired result:

• Professionally clean the siding so its original color and shadow lines can be evaluated accurately.
• Change the front door or shutter color to introduce contrast without altering the siding system.
• Update compatible trim or accessories after confirming product and installation requirements.
• Use shakes or scallops selectively in a gable rather than changing an entire elevation.
• Replace damaged sections with properly identified material, recognizing that aged and new material may not initially appear identical.
• Compare physical Gentek color samples against the roof, masonry and existing siding under morning, midday and late-afternoon light.

Questions to Ask Before Approving Any Coating

• Has the product been positively identified as Fairhaven Sound polypropylene siding?
• Has Gentek approved painting this exact product in writing?
• Which cleaner, preparation method, primer and topcoat has Gentek approved?
• Are there restrictions on color, solar reflectance, sheen or application temperature?
• How will overlaps, locks, joints and concealed panel areas be handled?
• Could the proposed work affect an existing or potential warranty claim?
• How will the new color coordinate with soffit, fascia, trim, roofing and masonry?
• Who will be responsible if the coating peels, changes sheen or reveals the original color at moving joints?

The Bottom Line

Fairhaven Sound shakes and scallops are designed to provide cedar-inspired texture and factory-selected color without the recurring painting associated with natural wood. Painting them should not be treated as ordinary exterior maintenance.

First identify whether the concern is dirt, damage, fading or simply a desire for a different palette. Then consult Gentek’s current instructions and warranty. Unless Gentek approves the exact coating system in writing, cleaning, inspection, selective replacement or a broader exterior-design adjustment is the more prudent path.
