Dicor Rubber Roof Products offer a complete system for maintaining, repairing, and renewing rubber roofing, primarily EPDM, across RVs and small commercial applications. This article explains key products, best practices, and maintenance tips to help users choose the right Dicor components for long-lasting performance.
Overview Of Dicor Rubber Roof Systems
Dicor Corporation specializes in roofing solutions for EPDM rubber roofs, including membranes, sealants, and coatings designed for weather resistance and ease of application. The core components include EPDM roof membranes, self-leveling lap sealants, non-sag sealants, and roof coatings. These products work together to install new roofs or restore existing ones, offering durable waterproofing and UV protection. Dicor emphasizes compatibility among its products to ensure a uniform performance standard across installations.
EPDM Rubber Roof Membranes
Dicor’s EPDM membranes are engineered for flexibility, weather resistance, and long service life. They’re typically used for RV roofs and small commercial units that require a durable, seamless surface. The membranes are designed to resist ponding water, resist ozone and UV damage, and maintain elasticity in temperature fluctuations. Proper substrate preparation, with a clean, dry surface and correct seam bonding, is essential for optimal results.
Key considerations: choose the correct thickness for the roof profile, ensure compatible fasteners or bonding techniques, and follow Dicor’s recommended cure times when applying coatings or sealants over the membrane.
Self-Leveling Lap Sealants
Dicor’s self-leveling lap sealants are used to seal horizontal joints and transitions on EPDM roofs. They provide a flexible, watertight seal that resists cracking and thermal cycling. These sealants are often applied at skylight bases, vents, and terminations to prevent leaks where water can accumulate. The self-leveling formula helps create a smooth, continuous bead that adheres well to rubber surfaces when properly prepared.
Application tips: clean and dry surfaces, remove old sealant residues, apply in moderate temperatures, and allow adequate curing time before exposure to rain. Use the recommended primer if specified for the joint material to maximize adhesion.
Non-Sag Sealants And Roof Coatings
Non-sag sealants are used for vertical seams, edges, and patches where a thick bead is required to withstand movement. Dicor’s non-sag products complement the self-leveling sealants by providing robust vertical sealing. Roof coatings, often applied over the EPDM membrane, enhance UV protection, reflectivity, and waterproofing. Coatings can extend roof life by mitigating chalking and weathering while maintaining flexibility through expansion and contraction cycles.
When selecting a coating, consider the roof’s exposure, color choice for heat management, and the coating’s compatibility with EPDM and existing sealants. Follow re-coating schedules to maintain optimal protection against moisture intrusion and UV degradation.
Maintenance And Care For Dicor Rubber Roof Systems
Regular maintenance is essential for maximizing the lifespan of Dicor rubber roof systems. Inspections should focus on seals around vents, skylights, and edges, as these are common leakage points. Cleaning should remove moss, algae, and debris that can trap moisture against the membrane. Avoid abrasive cleaners that could damage the EPDM surface; use mild soap with a soft brush or sponge and rinse thoroughly.
Maintenance checklist: inspect seams and sealants every 6–12 months, reapply sealants as needed, check for ponding water and ensure proper drainage, and track coating wear. If patches are required, use compatible Dicor products to maintain a continuous protective system. Seasonal weather changes can reveal vulnerabilities where prompt attention prevents costly leaks.
Installation Best Practices
Proper installation is critical for performance. The substrate should be clean, dry, and free of oils or debris. When applying EPDM membranes, follow Dicor’s guidelines for seam bonding, edge detailing, and flashing installation around penetrations. Temperature and humidity influence cure times for sealants and coatings, so plan installations during moderate weather. Use recommended primers and surface treatments to improve adhesion where required.
When replacing an entire roof, consider removing old materials entirely to prevent incompatible residue from compromising the new system. For small repairs, ensure compatible patch materials and allow sufficient curing before exposure to rain or foot traffic.
Selecting The Right Dicor Products For Your Roof
Choosing the right combination of Dicor products depends on the roof condition and goals. For a new EPDM roof, pair the membrane with a topcoat or coating to maximize UV resistance and longevity. For existing roofs with minor leaks, sealants and patches can address problem areas without a full roof replacement. In high-traffic RV roofs, thicker membranes and robust sealants may be preferable to resist wear.
Decision factors: roof condition, climate exposure, desired maintenance interval, and ease of reapplication. Always verify compatibility among all chosen Dicor products to ensure a cohesive system that performs as intended.
Curing, Drying, And Weather Considerations
Timing is essential for Dicor products. Cure times vary with temperature and humidity, and applying coatings or sealants in unsuitable conditions can compromise adhesion. If rain or dew is likely, postpone installations to prevent moisture entrapment. Temperature guidelines typically suggest specific ranges for applying self-leveling sealants and coatings. Protect fresh work from wind-driven debris and direct sunlight during the curing period.
For best results, monitor weather forecasts and schedule work during windows with moderate temperatures and low humidity. After application, avoid traffic on cured surfaces until full curing is achieved to maintain seal integrity.
Common Questions About Dicor Rubber Roof Products
- Are Dicor products compatible with all EPDM roofs? Yes, Dicor designs products to work together on EPDM membranes, but it is important to confirm compatibility with the specific product line you choose.
- How often should a Dicor roof be resealed or recoated? Maintenance intervals depend on climate, roof wear, and coating type; inspect annually and recoat or reseal as needed to maintain performance.
- Can Dicor products be used on metal, fiberglass, or other substrates? Dicor is optimized for EPDM; verify substrate compatibility and consider surface preparation requirements before use.
- Is professional installation recommended? For complex roofs or large units, professional installation ensures proper substrate prep and seam integrity; DIY can work for straightforward applications following instructions carefully.
Safety And Storage Considerations
Follow label directions for handling, ventilation, and protective gear when applying sealants or coatings. Store products in a cool, dry place away from direct sunlight and sources of ignition. Used containers should be disposed of according to local regulations. Keep products out of reach of children and pets during storage and use.
Tips For Longer Roof Life With Dicor
- Choose high-quality membranes and sealants that match the roof profile and exposure.
- Prepare substrates meticulously to ensure strong adhesion and seamless joints.
- Schedule regular inspections, especially after severe weather, and address issues promptly.
- Use compatible coatings to maintain reflectivity, UV protection, and flexibility.
- Document product types and application dates to plan future maintenance intervals.
