HB42 Ultimate Grab Adhesive - White - 290ml - Box of 23

Keep a full box of 23 HB42 Ultimate Super Grab Adhesive cartridges on hand for jobs that demand serious holding power. Built on instant grab technology, this trade-strength adhesive delivers almost double the bond strength of standard grab adhesives, bonds securely even in wet conditions, and works as a complete fixing solution - removing the need for secondary support in most applications.

Ideal for heavy-duty fixing across large panels, wallboards, windowsills, dado rails, brick slips, cladding and sanitary fixtures, both indoors and out. It bonds to an exceptionally wide range of substrates, including glass, wood, enamel, painted surfaces, plasterboard, coated metals, Perspex, concrete, plastics, polycarbonates, PVCu, zinc, stainless steel, copper, lead, anodised aluminium, and epoxy or polyester panels.

• Box contains 23 cartridges - ready supply for trade and heavy-duty projects
• Instant Grab Technology - near-double the bond strength of standard grab adhesives
• Bonds effectively in wet conditions, even underwater
• Handles heavy items - a genuine alternative to mechanical fixings
• Highly elastic - stretches up to 300% without failing
• Maintains bond line integrity over time with no shrinkage
• Solvent free and low VOC - EC1 Plus rated, GEV approved, virtually odourless
• Weatherproof formula suited to internal and external use
• Bonds to an extensive range of substrates, including lead

Limitations: Not recommended for use on PE, PP, Teflon, wax, neoprene or bituminous surfaces. Not suitable as a joint sealant. An adhesion test is recommended before full application. Contains N-(3-(trimethoxysilyl)propyl)ethylenediamine and related substances, which may cause an allergic reaction - refer to the safety data sheet before use.

• Ensure all surfaces are clean, dry and free from dust, grease and loose material.
• Carry out an adhesion test on the intended substrate before full application, especially on unfamiliar or coated materials.
• Cut the cartridge seal and screw on the pre-cut 'V' nozzle - this controls the correct depth of adhesive extruded.
• Load the cartridge into a skeleton gun for application.

• Apply HB42 Super Grab Adhesive to one surface only, in vertical strips approximately 30cm apart.
• Immediately place the item into position and apply even pressure across the surface to achieve good initial grab.
• For heavy items, use temporary support while the adhesive cures.
• For overhead applications, always use a mechanical fixing in addition to the adhesive.
• Apply at room temperature for optimum flow when using a skeleton gun.

Tip: Working within the +5°C to +40°C application range gives the best flow and initial grab performance.

Aftercare & Curing

• Keep fixed items supported (temporary support or mechanical fixings where recommended) until the adhesive has fully cured.
• Skin formation begins in around 10–15 minutes at 23°C / 55% RH, but full cure takes longer depending on bond line thickness and conditions.
• Once cured, the bond is weatherproof and water resistant, suitable for both internal and external use.
• Avoid disturbing or loading the fixed item until initial grab and cure are established.

Clean Up

• Wipe away excess uncured adhesive immediately using a dry cloth or paper towel.
• Uncured residue on tools and non-porous surfaces can be removed with a suitable solvent cleaner.
• Once cured, the adhesive is solvent-resistant and can only be removed mechanically (e.g. scraping or sanding).
• Reseal or replace the nozzle after use to prevent the cartridge curing in storage.

Storage

Store cartridges in cool, dry conditions between +5°C and +25°C. Under these conditions, shelf life is 12 months. Frost resistant down to -15°C during transport.
