Heng’s Rubber Roof Coating vs Dicor: RV Roof Coating Comparison

Heng’s Rubber Roof Coating and Dicor are popular choices for RV owners seeking durable, weatherproof protection for rubber roofing. This article compares these coatings across performance, application, longevity, and value to help readers choose the right product for their EPDM or rubber roof system.

Overview Of Heng’s Rubber Roof Coating

Heng’s Rubber Roof Coating is a breathable, elastomeric coating designed for rubber roofs on RVs. It aims to extend roof life by sealing minor cracks, resisting UV damage, and providing a flexible barrier that moves with roof expansion and contraction. The coating is known for ease of application, compatibility with most EPDM membranes, and a focus on simple maintenance for long-term protection.

Overview Of Dicor Roof Coatings

Dicor produces several roof coating products, including elastomeric sealants and coatings designed specifically for RV EPDM and rubber membranes. Dicor coatings are widely used in the RV industry, reputed for strong waterproofing, UV resistance, and compatibility with existing Dicor sealants and lap seals. Availability in multiple formulations allows users to select products tailored to flat or curved roof areas and varying climates.

Key Differences At A Glance

• Formulation Focus: Heng’s emphasizes flexible, breathable coatings for EPDM, while Dicor offers a broader lineup including dedicated sealants and roof coatings for different roof shapes and climates.
• Compatibility: Both work with EPDM rubber roofs, but Dicor’s ecosystem may provide more integrated options with other Dicor products (sealants, tapes, and accessories).
• Application Experience: Heng’s is often praised for straightforward application and easy cleanup; Dicor coatings can require more meticulous surface prep to ensure maximum adhesion.
• Longevity: Both offer durable protection, but actual lifespan depends on climate, maintenance, and roof condition. Dicor’s established market presence means more anecdotal long-term data from RV owners.
• Pricing And Availability: Heng’s pricing is typically competitive, while Dicor’s broad dealer network can influence price and availability in the U.S. market.

Performance And Longevity

Performance metrics for RV roof coatings rely on UV resistance, elasticity, and waterproof sealing. Heng’s Rubber Roof Coating generally delivers strong elasticity that accommodates the temperature swings common in many U.S. climates, helping to prevent cracking as the roof expands and contracts. Its breathable formulation aims to reduce moisture entrapment while maintaining a protective barrier against UV rays and weathering.

Dicor coatings also emphasize elasticity and waterproofing, with a track record of durable seals around seams and edges. The advantage of Dicor’s formulations is their tested compatibility with a wide range of roofing accessories and their reputation for effective sealing in high-UV environments. Longevity is improved with proper surface preparation, cleaning, and adherence to application guidelines.

Surface Preparation And application Tips

• Cleanliness: Thoroughly clean the roof and remove all dirt, oils, and debris before applying either product. A clean surface improves adhesion and coating longevity.
• Test Patch: Apply a small test patch to confirm adhesion and drying behavior on your specific EPDM membrane.
• Repair Prior Cracks: Seal or repair any significant cracks or damage with appropriate sealants before coating. This prevents entrapment of moisture beneath the coating.
• Even Coverage: Apply in thin, even coats, allowing adequate drying time between layers as per product guidelines. Avoid over-application that can lead to cracking or peeling.
• Ventilation And Weather: Choose dry, mild conditions with low humidity for best results. Extreme heat or cold can affect cure times and performance.

Weather Resistance And Maintenance

Both Heng’s and Dicor coatings provide UV resistance and a barrier against moisture. The choice may depend on regional weather patterns: dry, sunny climates benefit from robust UV protection, while humid regions rely more on moisture resistance and mildew control. Regular inspections—at least annually—help identify wear, peel, or micro-cracks that may require touch-ups or spot repairs to maintain a watertight roof.

Maintenance strategies for either product include cleaning to remove algae or moss growth and reapplying coating where wear is evident. For fans of in-season checks, looking for changes in sheen or areas that feel tacky or softened can indicate aging material needing attention.

Pros And Cons

• Heng’s Rubber Roof Coating — Pros: Easy application, strong elasticity, good for EPDM membranes, competitive pricing. Cons: Might require more frequent touch-ups in extreme climates, availability varies by region.
• Dicor Roof Coatings — Pros: Broad product lineup and strong sealing performance, proven track record in RV applications, compatibility with a wide range of accessories. Cons: Some formulations may require stricter surface prep and longer cure times, priced higher in certain markets.

Price, Availability, And Practical Value

Pricing for Heng’s and Dicor coatings varies by retailer, region, and product formulation. Dicor products are widely distributed in RV supply stores and online retailers, giving buyers convenient access and backup parts, seals, and accessories. Heng’s coatings can be more price-competitive but may depend on regional distributors. For buyers prioritizing ease of sourcing and an integrated ecosystem, Dicor’s products often present practical value due to the availability of compatible sealants, tapes, and lap sealant products.

Final Recommendation

For RV owners with EPDM rubber roofs seeking straightforward maintenance and reliable protection, Heng’s Rubber Roof Coating offers an accessible option with solid elasticity and easy application. For those who value a broader product ecosystem, strong sealing performance, and established compatibility with a range of roof accessories, Dicor’s coatings—alongside its accessory lineup—provide a compelling, long-term solution. In either case, proper surface preparation, adherence to manufacturer guidelines, and regular roof inspections are essential to maximize performance and extend roof life.
