Product Information
Full details
The Demsun A30 Nail Free Grab Adhesive is an essential solution for homeowners, contractors, and DIY enthusiasts who need to bond heavy building materials like skirting boards or architraves without the need for mechanical fasteners. This water-based, solvent-free adhesive offers an impressive initial grab and long-term durability, making it a cleaner, safer alternative to nails or screws. While it excels in versatility and indoor applications, users should note its 1-2mm per day curing rate, which requires surfaces to be properly braced or held in place until the bond fully sets.

FAQs
Can I use Demsun A30 outdoors?
Yes, it is resistant to temperatures from -10C to +80C, but it should not be used in areas subject to constant water immersion or heavy rain during the curing process.
How long until it is fully cured?
The adhesive cures at a rate of 1-2mm per day; a thicker application will require more time to achieve full strength.
Is this adhesive paintable?
Yes, once the adhesive has fully cured, it can be painted over with most standard interior paints.
Does it contain harmful solvents?
No, the A30 is a water-based, solvent-free formulation, making it safer for indoor use.
Will this work on metal surfaces?
It is designed for most common building materials, but always test a small, inconspicuous area if bonding non-porous materials like smooth metal or plastic.
Can I use a standard caulking gun with this tube?
Yes, the 310ml cartridge is designed to fit all standard manual or electric caulking guns.
Troubleshooting
Adhesive is not sticking immediately
Ensure the surfaces are clean and free of debris. Use the 'press and pull' method to increase the tackiness of the adhesive before the final bond.
Bond feels weak after 24 hours
The product cures at 1-2mm per day. If the adhesive layer is too thick, allow for more time before removing support, or ensure the joint is properly clamped.
Excess adhesive squeezing out of joints
Wipe away excess immediately with a damp cloth; once hardened, the adhesive must be removed mechanically with a scraper.

- Paintable once cured for a professional aesthetic

Setup, Compatibility & Care
To ensure maximum bond strength, ensure all surfaces are clean, dry, and free of dust or oil. Load the 310ml cartridge into a standard caulking gun, cut the nozzle at a 45-degree angle, and apply beads or dabs to one surface. Keep the product stored in a cool, dry area away from direct sunlight. While the adhesive is weather-resistant, it should not be exposed to standing water or constant dampness during the initial 48-hour curing phase. If accidental contact occurs with the skin, wipe away excess immediately with a damp cloth before the adhesive sets.
