Gravel BUR Silicone

Protect a prepared built-up asphalt roof with a bleed-blocked silicone overlay. Gravel BUR Silicone combines asphalt primer, compatible detail repairs and a KoolFlex finish to resist weathering and standing-water exposure.

Consider this silicone system for serviceable BUR roofs where sunlight, water retention and a worn surface are the main restoration concerns. Remove loose gravel and resolve wet or unstable areas first.

Design and specification coordination

Use these checks to connect the product record to a complete, project-specific assembly. The manufacturer documents and approved construction documents govern where they provide more specific requirements.

• Identify the existing substrate and verify adhesion, primer and repair requirements before coating.
• Confirm required coverage rate, wet and dry film thickness, number of coats and reinforcement at seams and penetrations.
• Record surface preparation, moisture limits, application temperature, weather window and cure time.
• Coordinate drainage, ponding-water limitations and treatment of rust, blisters, wet insulation and failed details.
• Use the current product data and safety data sheets together when planning storage, handling and application.

Submittal and field verification

A useful product record should allow a reviewer to trace what was specified, approved, delivered and installed. Include the following items when this product is proposed or verified.

• Use the exact product name and manufacturer identifier on the submittal; do not substitute a similar family name.
• Attach the current product data sheet and the applicable installation, safety, approval and warranty documents.
• Record selected options such as size, thickness, profile, color, finish, reinforcement and attachment method.
• Identify the tested or approved assembly and list each adjoining component needed to reproduce it.
• At delivery, compare labels and revision dates with the approved record and archive superseded files instead of overwriting them.

Selection, installation and existing-roof checks

Confirm the exact product name, generation and configuration before using any value on this page. Check the roof substrate, slope, attachment or adhesive, reinforcement, edge and penetration details, accessories, tested assembly and local approval that apply to the project. For an existing roof, compare labels, package records, original submittals and physical dimensions; appearance alone is not enough to identify a product.

Your roof substrate

BUR means built-up roofing: layers of reinforcing felt and asphalt, often finished with gravel. Once loose gravel is vacuumed away, the exposed surface can be irregular and uneven. The coating must follow that prepared surface and connect to repaired flashings, drains and roof transitions.

Where to use this system

Consider this silicone system for serviceable BUR roofs where sunlight, water retention and a worn surface are the main restoration concerns. Remove loose gravel and resolve wet or unstable areas first.

Preparation and adhesion

Vacuum away loose gravel and clean the exposed roof. Repair weak flashings, splits and transitions, and check whether moisture or damaged insulation calls for localized replacement. Do not spray over loose aggregate. Use the specified bleed-block treatment beneath a silicone finish on the asphalt surface.

How the coating layers work

Apply the specified asphalt bleed-block primer after gravel removal and roof repairs. Complete compatible detail treatment, then install KoolFlex Premium Silicone to the required cured thickness. Plan future maintenance around compatible silicone recoats.

Coating thickness

Specify the minimum cured silicone thickness for your chosen assembly and allow separately for primer and detail treatment. The KF-600 sheet has conflicting coverage and wet-film figures. Its 20-mil NSF entry is not a roof-warranty thickness schedule; use the corrected roof-system application schedule.

Guarantee options

KF-600 KoolFlex Premium Silicone offers full-system limited warranty options from 5 to 20 years. Select the written option for your roof, then confirm the required coating build, preparation, inspections and maintenance. A component sheet alone does not establish your project’s coverage.

Care and recoating

Inspect the roof at least twice a year and after severe weather or work on rooftop equipment. Keep drains clear, check flashings and penetrations, and repair damage with compatible materials. Confirm the surface preparation and compatibility requirements before any future recoat.
