It also contains a fungicide for sealing joints in warm, humid environments where there is a likelihood of mould growing. The joint width must be designed to suit the movement capability of the sealant. In general, the joint width must be > 10 mm and < 35 mm. Apply adhesive onto the surface of one of the elements to be bonded: In spots to smooth uneven surfaces, in wave-like form for higher initial tack with large surfaces or in straight beads for smaller surfaces. Release gun after appliance to stop the adhesive flow. (Not valid for Foldable Gun DW111/120). Firmly fix items to be bonded into position with a twisting action. If necessary (e.g., heavy items and items under tension), support the items until cured. Items can be adjusted after application. The minimum thickness of the adhesive layer should be 1 mm to ensure ventilation. The sealant will be touch dry in 30 minutes. The box includes 2 x UniBond Seal and Bond Sealant Cartridge Translucent, 291g.
The UniBond Seal & Bond Sealant Cartridge is a versatile, polymer-based sealant and adhesive designed for both indoor and outdoor applications. It is ideal for DIY enthusiasts and professionals needing a reliable solution for sealing joints and bonding materials, particularly in areas prone to moisture and mould due to its integrated fungicide. A key benefit is its dual functionality as both a sealant and a strong adhesive. However, users should ensure that joint widths are within the recommended 10mm to 35mm range for optimal performance.

FAQs
What is the ideal joint width for this sealant?
The joint width must be designed to suit the movement capability of the sealant. In general, the joint width must be greater than 10 mm and less than 35 mm.
Can I use this product in a wet environment like a shower?
Yes, the product contains a fungicide for sealing joints in warm, humid environments where there is a likelihood of mould growing, making it suitable for bathrooms and kitchens.
How long does it take to cure completely?
The sealant will be touch dry in approximately 30 minutes. Full cure times can vary depending on temperature, humidity, and joint depth, but typically takes 24-48 hours for full strength.
Can I adjust items after applying the adhesive?
Yes, items can be adjusted after application. However, for heavy items or those under tension, support them until the adhesive is fully cured.
What type of surfaces can this product bond to?
It bonds to most common building materials including wood, metal, glass, ceramics, concrete, and some plastics. Always test on a small area first if unsure.
What does 'touch dry' mean for this product?
'Touch dry' means the surface will not transfer wet product to a lightly touching finger. It does not mean the product is fully cured or has reached maximum strength.
Can this be used with foldable sealant guns?
No, the application instructions state it is not valid for Foldable Gun DW111/120.
Troubleshooting
Product not dispensing from the cartridge.
Ensure the nozzle tip has been cut and that the cartridge is correctly loaded into the sealant gun and the gun's trigger mechanism is engaged properly.
Poor adhesion or sealant failure.
Verify that surfaces were clean, dry, and free from contaminants before application. Ensure the joint width is within the recommended 10-35mm range for sealant applications.
Mould reappearing after sealing.
While the product contains a fungicide, persistent mould issues may indicate underlying moisture problems that need to be addressed. Ensure adequate ventilation in the area.
Uneven bead application.
Practice with the sealant gun on a scrap piece of material. Ensure consistent pressure and speed during application. Tool the bead immediately after application for a smooth finish.
Pros and Cons
Pros
Multi-functional: Serves as both a sealant and an adhesive.
Mould resistant due to its fungicide content.
Suitable for a broad range of applications, both interior and exterior.
Offers good adhesion strength for various bonding tasks.
Dries quickly to a touch-dry state.
Cons
Requires specific joint widths (10-35mm) for optimal sealant performance.
May require temporary support for heavy bonded items until fully cured.
Not suitable for use with specific foldable sealant guns (DW111/120).
Setup, Compatibility & Care
Setup:
Ensure the surfaces to be bonded or sealed are clean, dry, and free from dust, grease, and loose material.
Cut the nozzle tip to the desired bead size.
Screw the cartridge onto a standard sealant gun.
Apply the sealant or adhesive using the gun, ensuring consistent pressure.
For adhesive use, firmly fix items into position with a slight twisting action.
For sealant use, tool the bead immediately after application for a neat finish.
Compatibility:
Suitable for bonding and sealing most common building materials, including wood, metal, glass, ceramics, concrete, and some plastics. Always test on a small, inconspicuous area first if unsure.
Ensure joint dimensions are between 10mm and 35mm for optimal sealing performance.
Not compatible with foldable sealant guns DW111/120.
Care:
Keep the cartridge cap on tightly when not in use to prevent the product from drying out.
Clean up any excess uncured product immediately with a damp cloth or appropriate solvent (check product for specific recommendations).
Once cured, the product can typically be cleaned with a damp cloth. Avoid abrasive cleaners.
