Customer Reviews
John from the United States
I used this tape to seal some cracks in my garage roof after a heavy rain season. It stuck well without needing extra tools, and so far, it's held up through a few storms without any leaks showing up. The roll was easy to cut and apply, though I had to make sure the surface was clean first. Overall, it did what I needed for the price.
Emma from the United Kingdom
Applied this to the seams around my greenhouse windows where water was seeping in. The self-adhesive backing made installation straightforward, even in cooler weather. It's been a couple of months, and the seal seems solid—no more drips inside. I appreciate that it didn't require heating or messy glues, which suited my DIY setup.
Liam from Australia
We get a lot of sun and occasional downpours here, so I tried this tape on my shed's metal roof joints. It adhered properly after pressing it down, and it hasn't peeled off despite the heat. The flexibility helped with the uneven surfaces. Not the thickest material I've used, but it stopped the leaks effectively for my needs.
Sophie from Canada
In our cold winters, I needed something for sealing basement window frames against moisture. This tape went on easily without cracking in the low temperatures, and it's prevented water from getting in during thaws. The length per roll was sufficient for multiple spots. It's a practical option if you're looking for a no-fuss waterproofing fix.
Hans from Germany
I applied it to repair seals on my balcony railing connections where rain was causing rust issues. The adhesion was reliable on concrete and metal, and it conformed to the shapes without bubbles. After several weeks of variable weather, it's still in place. Good for small-scale repairs, though I'd test compatibility with your surfaces first.
Comparison to Silicone Sealants
The Asphalt Self Adhesive Waterproof Tape and silicone sealants both serve as waterproofing solutions but differ in composition, application, and performance based on specific use cases. Below is a side-by-side comparison drawing from industry insights.
| Aspect | Asphalt Self Adhesive Waterproof Tape | Silicone Sealants | Notes |
|---|---|---|---|
| Material Composition | Typically consists of polymer-modified asphalt with reinforcements like polyester or fiberglass, backed by a self-adhesive layer. | Made from silicone polymers, often available in tube form for caulking. | Asphalt tapes are more akin to butyl tapes in flexibility and adhesion, while silicones provide a different chemical resistance. |
| Application Method | Applied cold as a roll; self-adhesive, requires clean surface and pressure for bonding; no tools needed beyond cutting. | Applied via caulking gun; requires curing time (hours to days) and may need primers on some surfaces. | Tape is simpler for DIY and quick fixes, especially in fire-restricted areas, but silicone allows for filling irregular gaps. |
| Adhesion and Compatibility | Strong on porous or uneven surfaces like concrete, metal, and asphalt; may not bond well to silicone-treated materials. | Versatile on glass, metal, and plastics; poor adhesion to asphalt or bituminous surfaces without preparation. | Compatibility checks are essential; asphalt tape excels on roofing materials where silicone might peel. |
| Flexibility and Elongation | High elongation (often over 1000%), accommodates substrate movement without cracking. | Moderate flexibility (100-300% elongation), but can become brittle over time in extreme conditions. | Tape handles expansion joints better, while silicone suits static seals. |
| Durability and Weather Resistance | Resists UV, temperature extremes (-40°F to 200°F), and chemicals; self-healing for minor punctures; longer lifespan in outdoor exposures. | Excellent UV and moisture resistance, but may degrade faster under constant ponding water or mechanical stress. | Asphalt tape often provides longer-term seals in roofing; silicone is preferred for flat roofs with standing water. |
| Waterproofing Effectiveness | Forms a continuous barrier; excellent for seams and joints, but less ideal for high-moisture immersion like bathrooms. | Superior in constant wet areas due to non-porous nature; effective for gaps but can shrink during curing. | Neither is universally better; tape may underperform in prolonged moisture compared to silicone. |
| Cost and Availability | Generally cost-effective for covering larger areas; available in rolls of various widths. | Often cheaper per unit but requires more labor; widely available in hardware stores. | Tape saves on application time, potentially reducing overall costs for repairs. |
| Limitations | Not suitable for high-heat applications or where frequent removal is needed; can be messier if not applied correctly. | Curing time needed; less effective as an adhesive compared to sealants designed for bonding; potential for mold in some formulas. | Choice depends on the project—tape for quick, flexible seals; silicone for precise, gap-filling work. |
Overall, the choice between the two depends on the specific requirements, such as surface type and environmental conditions, with no one option being inherently superior across all scenarios.
Frequently Asked Questions (FAQ)
What surfaces can the Asphalt Self Adhesive Waterproof Tape be applied to? The tape adheres to a variety of surfaces including concrete, metal, asphalt, wood, and some plastics. It's best suited for clean, dry, and non-porous materials. Always test a small area first to ensure compatibility, as it may not bond well to silicone-treated or oily surfaces.
How do I apply the tape? Clean the surface thoroughly to remove dust, grease, or moisture. Peel off the release liner, press the tape firmly onto the area, and use a roller or hand pressure to ensure full contact. Overlap seams by at least 2 inches for better sealing. No heat or additional adhesives are required, making it suitable for cold application.
How long does the tape last once applied? Under normal conditions, it can last 5-10 years or more, depending on exposure to UV, temperature fluctuations, and mechanical stress. In extreme environments like high heat or constant moisture, lifespan may be shorter. Regular inspections are recommended for outdoor uses.
Is the tape fully waterproof and can it handle standing water? It provides a reliable waterproof barrier for seams, cracks, and joints, but it's not designed for prolonged immersion or areas with constant ponding water. For such cases, it works best as part of a larger waterproofing system.
Can the tape be removed or repositioned after application? Once fully adhered, removal can be difficult and may leave residue. It's intended for permanent fixes. If repositioning is needed shortly after application, it can be done carefully, but adhesion strength increases over time.
What temperatures can the tape withstand? It performs in temperatures from -40°F to 200°F (-40°C to 93°C). Application is recommended between 40°F and 100°F (4°C to 38°C) for optimal adhesion. In very cold conditions, warming the tape slightly can help.
Is this tape environmentally friendly and safe to use? The tape produces no toxic fumes during application and is free from solvents. It's considered low-VOC, but proper ventilation is advised in enclosed spaces. Disposal should follow local regulations for asphalt-based materials.
What sizes and thicknesses are available? Common widths include 2 inches, 4 inches, and 6 inches, with lengths up to 50 feet per roll. Thickness typically ranges from 1mm to 2mm. Custom sizes may be available depending on the supplier.
How does it compare to other waterproofing options like caulk or liquid sealants? Unlike caulk, which requires curing time and a gun for application, this tape is ready-to-use and self-adhesive for quicker installation. It offers higher flexibility for moving surfaces but may not fill deep gaps as effectively as liquid options.
Can it be used indoors, such as in bathrooms? Yes, it's suitable for indoor areas like bathrooms for sealing around tubs, showers, or tiles. Ensure the surface is dry before application, and it can handle humidity well, though it's not meant for direct submersion.
