Gorilla Heavy-Duty Grab Adhesive 80ml is a trade-strength, multi-purpose construction adhesive engineered to provide an instant, high-grip bond on heavy items. Traditional household glues often lack the initial tack required to hold objects on vertical surfaces, leading to slipping, sagging, and the tedious need for temporary support structures. This 80ml tube offers an advanced, flexible formula that grabs surfaces immediately, eliminating the need for nails, screws, or brackets on many mounting tasks. It cures to a tough, weather-resistant weld that withstands structural shifting, impacts, and intense environmental stress. Whether you are installing heavy bathroom fixtures, mounting interior molding, or fixing loose outdoor brickwork, this grab adhesive ensures a fast, permanent bond that saves time on the job.

Key Features and Specifications

This professional-grade adhesive features a high-density, non-slump paste consistency that fills gaps seamlessly, making it highly effective on rough, uneven, or textured substrates. The 80ml volume is housed in a convenient, squeezable tube that is perfectly sized for targeted repairs and toolbox storage, bypassing the need for a separate caulking gun. The formula is 100% waterproof and highly resistant to extreme temperature fluctuations, making it fully versatile for both internal rooms and exposed external construction. It delivers an incredibly versatile hold across an extensive range of materials, including wood, drywall, plaster, brick, concrete, stone, metal, glass, ceramics, and most rigid plastics.

How to Use

To secure an unyielding bond, ensure that all target surfaces are completely clean, dry, and free from old adhesive, grease, loose dust, or flaking paint; glossy surfaces should be lightly sanded to optimize physical grip. Cut the plastic nozzle tip to your desired bead thickness and peel back the inner seal if present. Apply the adhesive in continuous zig-zag or vertical beads to one of the surfaces, ensuring even coverage and avoiding the outer edges to prevent messy squeeze-out. Press the object firmly against the target surface, sliding it slightly to distribute the adhesive evenly, and hold it under firm pressure for a few seconds to engage the instant grab. Although it grabs immediately, heavy objects or vertical installations may require temporary bracing or tape for the first 24 hours until full cure is reached.

Advantages and Disadvantages

The primary advantage of Gorilla Heavy-Duty Grab Adhesive is its exceptional initial tack, which allows users to mount fixtures to walls and ceilings instantly without watching them slide or fall out of place. The gap-filling capability provides a major benefit when bonding irregular materials like natural stone or rough-sawn timber, ensuring complete structural contact. A potential disadvantage is that because the paste is exceptionally thick and fast-grabbing, there is a very limited window for sliding or repositioning components once they are pressed into place. Additionally, while highly compatible with standard building materials, it is not recommended for use on flexible plastics like polyethylene and polypropylene, or for mirrors where the chemical backing could be compromised.

Delivery and Shipping

We use reliable courier services to ensure your hardware and adhesive supplies are delivered safely and efficiently to your door. Standard delivery typically takes between 2 to 4 working days.

Safety, Compliance and Disclaimers

Store the tube upright in a cool, dry place away from direct sunlight, and always wipe the nozzle clean before firmly replacing the cap to prevent the remaining adhesive from hardening inside the tip. Keep out of reach of children and pets. This product contains chemicals that can cause mild skin and eye irritation; always work in a well-ventilated space and wear protective disposable gloves during application. In case of contact with skin, wipe off immediately with a dry cloth and wash thoroughly with plenty of soap and water. Standard disclaimer: Ultimate load-bearing limits are heavily dependent on surface preparation, material composition, and correct application technique; always verify that the substrate can support the weight of the item being mounted.

FAQs (Frequently Asked Questions)

Do I need a caulking gun to use this 80ml version?

 No, this specific 80ml variant is packaged in a convenient, flexible squeeze tube, allowing you to apply the adhesive directly to your project by hand without requiring an external caulking gun.

Can I use this grab adhesive to mount a heavy mirror in my bathroom?

 We do not recommend using this construction adhesive directly on the back of mirrors, as the powerful chemical formulation can potentially react with and damage the silver reflective backing over time. For mirrors, always use a specialized mirror-safe silicone or mechanical brackets.

How long does it take for this adhesive to dry completely?

 The adhesive forms an immediate, high-strength initial grab upon contact. However, it requires a full 24 hours to cure completely and reach its maximum structural holding capacity, during which the joint should not be subjected to heavy loads.
