Sika Stixall Maximum Grab holds twice as hard and twice as fast as standard grab adhesives. No propping, no taping, no clamping. Bonds to most surfaces wet or dry, indoors and out, and cures to a tough, flexible, weatherproof seal.
Most grab adhesives will get the job done eventually, but they have a habit of asking for patience you do not have on site. Prop this, tape that, come back in an hour. Sika Stixall Maximum Grab is built for when that is not an option. Its initial grab is typically double that of standard grab adhesives, which means the moment you press something into place, it tends to stay there. Brick slips, mirror panels, cladding, skirting — press, hold briefly, move on.
This is a hybrid polymer adhesive and sealant in one, so it is doing two jobs from a single cartridge. No primer needed on most surfaces, including metal, glass, concrete, plaster, wood, most plastics, and even painted surfaces. More usefully, it works on damp and wet substrates, which is the kind of thing that catches you out when you are trying to get a fix on exterior masonry or a slightly sweating tile surface.
Once cured, Sika Stixall Maximum Grab sets to a flexible rubber rather than going hard and brittle. That matters on jobs where there is movement — thermal expansion, vibration, or surfaces that work slightly in wind. A rigid bond in those situations will crack. A flexible one keeps working. It is also overpaintable once fully cured, resistant to chemicals and petrol, and completely waterproof, so it holds its own on exterior applications without any further treatment.
Where Sika Stixall Maximum Grab Earns Its Place
The no-support benefit is the headline, but the breadth of what it sticks to is what makes this a genuinely useful cartridge to have on the van. Skin time is around 20 minutes and full cure progresses at roughly 2mm per day, so it is not a race once it is applied, but the initial grab gives you the freedom to move to the next task without babysitting the bond. Interior or exterior, above or below the damp proof course, most trades will find a use for it fairly quickly.
Supplied in a standard 290ml cartridge, compatible with most skeleton guns. White finish, and overpaintable when you need it to disappear into the job.
Pro Tip: On vertical applications with heavy materials, a 10-second firm press with your palm after application gives the initial grab the contact it needs to really take hold — do not just touch and let go.
Sika Stixall Maximum Grab is used wherever a fast, reliable bond is needed without the luxury of time to clamp or support. Common applications include fixing brick slips and stone veneers, bonding mirrors and glass panels, installing skirting boards and architraves, securing cladding and composite panels, and general interior and exterior construction bonding. It performs equally well on damp substrates, making it particularly useful for exterior masonry work or areas prone to condensation.
Builders, joiners, tilers, cladding installers and general contractors all find regular use for it. The combined adhesive and sealant action makes it practical anywhere a standard grab adhesive would leave a gap that still needs filling or sealing separately.

Interior and exterior use
Not suitable for: Not recommended for polyethylene, polypropylene or PTFE surfaces, which resist adhesion from most polymer-based products. Check suitability before use on structural or load-bearing applications where approved structural adhesives may be required.
Load the 290ml cartridge into a standard skeleton gun and cut the nozzle tip at an angle to suit the bead size you need. Apply in a continuous bead or dot-and-dab pattern depending on the substrate and panel size. Press the surface firmly into position and hold briefly — the high initial grab means most materials will stay in place without further support.
Clean up any squeeze-out before skinning begins, around 20 minutes after application. Full cure progresses at approximately 2mm per day, so avoid stressing the joint in the first 24 hours on heavier applications. The surface can be painted once fully cured.
Load the 290ml cartridge into a compatible skeleton gun and cut the nozzle at a 45-degree angle
Ensure surfaces are clean, dust-free and structurally sound — damp surfaces are fine, but loose material or contamination will affect the bond
Apply a continuous bead or a dot-and-dab pattern depending on the panel size and weight
Press the component firmly into position and hold for several seconds to allow initial grab to take effect
Remove any excess adhesive with a damp cloth or tool before the 20-minute skin time is reached
Leave undisturbed for at least 24 hours before applying any significant load to the bond
Once fully cured, overcoat with paint if required
Does Sika Stixall Maximum Grab really work without propping or clamping?
For most standard applications, yes. The initial grab is typically double that of conventional grab adhesives, which means materials like brick slips, mirrors and cladding panels will hold in position after a firm press without needing temporary support. On unusually heavy or large panels, a brief support while the first few minutes pass is always sensible, but for typical jobs it performs as described.
Can it be used outdoors and on wet surfaces?
Yes to both. Sika Stixall Maximum Grab is fully waterproof and weatherproof once cured, and is rated for exterior use. It will also bond to damp and wet substrates, which makes it more practical than many alternatives when conditions are not ideal on site.
What gun does the 290ml cartridge fit?
The 290ml cartridge is a standard size compatible with most skeleton guns, including both manual and pneumatic options. Nothing specialist needed.
How long does it take to fully cure?
Skin time is around 20 minutes. Full cure progresses at approximately 2mm depth per day, so a standard bead will be through-cured within a couple of days. Avoid stressing the joint heavily in the first 24 hours on loaded applications.
Sika Stixall Maximum Grab is a single-component hybrid polymer adhesive and sealant. It cures by reaction with atmospheric moisture, forming a flexible rubber that maintains adhesion and elasticity across a wide temperature range. The formulation is solvent-free, making it suitable for use in enclosed spaces. It meets the demands of both interior and exterior applications, offering resistance to UV, chemicals, petrol and prolonged water exposure once fully cured.
