| How are horizontal repairs reinforced with fleece? | Apply a thin first coat, immediately embed fleece, and apply a thick topcoat while the first coat is wet. Overlap adjoining fleece by 1/2 inch with sealant between the layers. Fully cover the fleece. | Apply a thick first coat, immediately embed fleece, and apply a thick topcoat. No wait is needed between these layers. Fully cover the fleece so no fabric pattern or exposed fleece remains visible. |
| How are upright flashing transitions repaired? | Bridge compatible, clean, dry wall and metal surfaces with fleece embedded in sealant, then fully cover the fleece. Existing groove filler can remain if it is not loose or preventing the fleece from lying flat; the repair must bond to the exposed compatible surfaces. | Apply a thin first coat and let it become tacky. Embed fleece and add another thin coat. Wait 30–45 minutes before the additional coat that fully covers the fleece. |
| How are metal-roof screws sealed? | After tightening the screw and seating the washer flat, cover the screw head and washer with a dab of sealant. No fleece is needed over the screw. | After tightening the screw and seating the washer flat, cover the screw head and washer with a dab of sealant. No fleece is needed over the screw. Patch abandoned screw holes with fleece and sealant. |
| How are metal-roof seams repaired? | Fasten separated panels tightly together before sealing. Reinforce the seam with fleece and sealant, following the panel profile. Keep seam fleece off the screws and seal screw heads separately. | Fasten separated panels tightly together before sealing. Reinforce the seam with fleece and sealant, following the panel profile.

| Can it repair gutter seams? | Yes. Secure loose joints with commercial rivets, clean and dry the area, and seal from inside the gutter with fleece following the bottom and both sides. | Yes. Secure loose joints with commercial rivets, clean and dry the area, and seal from inside the gutter with fleece following the bottom and both sides. |
| Can it repair a concrete chimney crown? | Yes. Reinforce every crack with fleece and fully cover it. One coat on concrete covers approximately 15 square feet per 1/2 gallon; areas reinforced with fleece require more material. | Yes. Reinforce every crack with fleece and fully cover it. Follow the chimney-crown preparation and repair instructions; the surface must be completely dry. |
| Which skylight repairs can it be used for? | Primarily skylight curb flashing, especially curb corners. It can also seal the documented Plexiglas-to-metal-frame transition. It does not adhere to glass and is not a solution for every skylight leak. | It can seal compatible glass- or Plexiglas-to-frame joints using sealant and fleece. Clean and prepare the bonding areas, embed and fully cover the fleece, and remove masking tape immediately after the topcoat. |
| Can it repair a cracked EPDM vent boot? | Only as the documented reinforced cover anchored to the pipe above and the compatible roof surface below. It does not bond to EPDM. Follow the full vent-boot repair instructions. | Yes. Reinforce with fleece extending onto the pipe and compatible surrounding roof surface. Follow the thin-coat vertical method on upright sections. |
| What application temperatures are recommended? | Recommended air temperature: 20–110°F. Ideal: 25–90°F. The surface must be completely dry; cold weather slows curing and high heat makes the sealant runnier. | Recommended air temperature: 20–110°F. Ideal: 25–90°F. The surface must be completely dry. Cold weather delays rain readiness and curing. |
| How soon can rain fall on the repair? | Allow approximately 10–15 minutes as a conservative estimate; about 5 minutes may be enough on a warm day. Surface skin formation is different from full cure. Cold-weather timing varies. | Allow about 30 minutes on a warm day. Below 32°F, allow 3–4 hours. Rain readiness is different from full cure. |
| How long does curing take? | Allow approximately 24–48 hours as conservative guidance. Heat speeds curing; cold conditions slow it. | Allow approximately 24 hours under suitable conditions. Cold weather can extend curing time. |
| Can it be recoated with the same sealant? | A fresh repair can receive another coat within a few hours. Once cured, wait 6–12 months for the standard maintenance recoat and wipe the uncoated surface with a dry rag. Earlier recoating or repairs covered with paint or Silver Coat require the separate preparation instructions. | Yes. There is no mandatory waiting period for adding more sealant to a fresh repair, apart from the waits in the vertical application method. For an older repair, wipe clean with a wet rag and let it dry completely. |
| Can it be painted or given a protective coating? | Yes. Silver Coat or non-fibered aluminum asphalt is recommended for protective coating; paint can also be used. Follow the separate protective-coating instructions. | No paint or protective topcoat is needed. The sealant is UV-resistant and not paintable. It can be recoated with Super Silicone Seal. |
| How long can a properly applied repair last? | Bergstrom Industries estimates approximately 10–12 years without a protective coating. Actual service life depends on preparation, application and conditions. | Bergstrom Industries estimates approximately 12–20 years. Actual service life depends on preparation, application and conditions. |
| How should containers be stored? | Store tightly sealed in a cool place. Recommended use: unopened within 3–4 months of shipping; opened within 3–6 months.
