What Materials Will Adiseal Grey Stick To?
Adiseal is a universal MS polymer engineered to bond virtually most materials. It replaces the need for specialized wood glues, masonry adhesives, and plastic sealants.
| Surface Category | Compatible Materials | Professional Application |
|---|---|---|
| Masonry & Stone | Concrete, Brick, Granite, Marble, Slate, Limestone, Travertine | Ideal for paving, wall capping, and non-staining stone cladding. |
| Metals | Steel, Aluminum, Lead, Copper, Iron, Zinc | Perfect for gutter repairs, flashing, and structural metal-to-concrete bonding. |
| Plastics & Synthetics | PVC, ABS, Polycarbonate, Fiberglass, GRP, Polystyrene | Used for roofing sheets, window frames, and plumbing fixtures. |
| Wood & Timber | Hardwood, Softwood, MDF, Plywood, Chipboard | Provides a waterproof bond that won’t rot or weaken in damp environments. |
| Glass & Ceramics | Clear Glass, Mirrors, Porcelain, Tiles, Quartz | Securely bonds mirrors (non-corrosive) and kitchen/bathroom tiles. |
| Roofing Materials | Felt, Asphalt, EPDM, Bitumen, Shingles, Rubber (natural) | Instant emergency leak repair on major roofing substrates. |
(Note: Not suitable for polypropylene, polyethylene, or polyurethane).
Why Adiseal Bonds Better to Different Materials:
- Non-Porous Excellence: Unlike water-based grab adhesives that require one surface to be porous to dry, Adiseal cures via atmospheric moisture. This allows it to bond two completely non-porous surfaces (like metal to glass) quickly and effectively.
- Anti-Stain Technology: Many low-grade construction adhesives “bleed” oils into natural stone, granite, or marble, causing permanent staining. Adiseal’s chemically inert formula ensures zero oil migration into porous materials.
- Vibration & Expansion Resistance: On materials highly prone to environmental movement (like metal roofing sheets or wood flooring), Adiseal acts as a permanent shock absorber, maintaining a flexible bond during extreme thermal expansion and contraction.
Universal Sealing Capabilities: Watertight in Any Environment
Adiseal is not just a heavy-duty adhesive; it functions as a high-performance, industrial-grade sealant. Its advanced MS-polymer core creates a permanently flexible, watertight barrier that will not crack, shrink, or pull away from joints over time.
| Sealing Category | Key Applications | Professional Benefit |
|---|---|---|
| Sanitary & Wet Rooms | Baths, showers, basins, sinks, wet room joints, and kitchen worktops. | Advanced Mould Resistance: Stays clean, hygienic, and black-mould-free longer than standard silicones. |
| Roofing & Drainage | Gutters, downpipes, valley liners, roof flashing, and roofing felt patches. | Instant Wet-Surface Seal: Can be applied directly into heavy rain and standing water to stop active leaks instantly. |
| Windows & Glazing | Perimeter window frames, external door frames, skylights, and glass panels. | UV & Weatherproof Stability: Will not discolor, degrade, or become brittle under direct sunlight or frost. |
| Marine & Automotive | Boat hulls, deck fittings, campervan joints, caravans, and vehicle bodywork trims. | Vibration Proof: Absorbs continuous mechanical, engine, and acoustic vibrations without breaking the seal. |
| External Masonry | Expansion joints, brickwork cracks, concrete paths, and stone perimeter walls. | Zero Bleeding: Inert formula prevents unsightly oil migration and staining on porous concrete and stone. |
| HVAC & Ducting | Ventilation ducting, air conditioning units, and internal pipe seals. | Low Emission & Odour: Certified EC1 Plus, making it safe and virtually odourless for confined internal spaces. |
The Technical Advantage: Why Adiseal Outperforms Standard Sealants
- Displaces Water Instantly: Standard silicone requires a perfectly dry surface to stick. Adiseal’s dense hybrid polymer structure actively pushes water away from the substrate, allowing you to seal a bursting gutter or pipe while it is actively leaking.
- Permanent Elasticity: Many construction sealants dry rigid, causing them to crack when buildings naturally settle or expand in the heat. Adiseal remains elastomeric, flexing with the building’s movement.
- Paint Safe: Unlike traditional silicone—which completely repels paint—Adiseal can be neatly over-painted with most water-based coatings as soon as it skins over, allowing for a completely seamless finish.

Frequently Asked Questions About Adiseal Grey Adhesive Sealant
Is Adiseal Grey suitable for lead flashing and roof repairs?
Yes. Adiseal Grey is the professional choice for lead flashing, gutters, and roofing. It provides an instant waterproof seal even in driving rain and is highly UV resistant. Unlike standard bitumen or silicone, it will not crack or lose adhesion over time, ensuring a permanent, flexible bond on lead, aluminum, and felt.
What is the bond strength of Adiseal Grey?
Adiseal Grey is proven as the strongest adhesive and sealant in independent testing by Ultimate Handyman. It reached a record-breaking tensile strength of over 3123 psi, performing over 3 times stronger than leading competitors. It was the only product tested where the adhesive bond did not break.
Will Adiseal Grey stain or bleed on natural stone or marble?
No. Adiseal Grey is a high-quality MS polymer that is specifically formulated to be non-staining. It will not bleed into porous materials like natural stone, marble, granite, or masonry. This makes it ideal for architectural projects and stone installations where maintaining the aesthetic finish is critical.
Professional Tip: To seal leaking gutters in heavy rain, apply Adiseal Grey directly into the standing water. It creates an instant waterproof bond and seal that standard silicones cannot achieve.
How To Apply Adiseal Grey for the Best Results
How to Apply Adiseal Adhesive Sealant for a Professional Bond
Prepare and Clean the Surfaces
For the strongest possible bond, ensure surfaces are free from dust, grease, and loose material. While Adiseal works on wet surfaces, removing heavy debris first improves initial contact. If applying to metal, a quick wipe with a solvent-based cleaner is recommended.
Prepare the Adiseal Cartridge
Cut the top off the threaded plastic stud on the 290ml cartridge. Screw on the included nozzle and cut it at a 45-degree angle. For heavy bonding, a wider opening is better; for fine sealing, keep the opening small. Place the cartridge in the caulking gun / sealant applicator.
Apply the Adhesive or Sealant
For Bonding: Apply Adiseal in vertical strips (beads) rather than blobs. This allows essential air circulation for faster moisture-curing. Press the two materials together firmly.
For Sealing: Apply a continuous bead into the joint. For underwater repairs, apply the sealant directly into the leak; the MS-polymer technology will displace the water to create an instant seal.
Tool and Finish the Joint
Smooth the sealant immediately after application. Use a profiling tool or a finger dipped in a soapy water solution. Adiseal remains flexible and does not shrink, so it will maintain its shape as it cures.
Allow for Curing Time
Adiseal has a high initial grab. Under normal conditions, it skins over in 10–20 minutes and is recommended 48 hours to fully cure.
Other colours Adiseal adhesive sealant is available include: White, Black, Brown, Ultra Clear.
