FAQs
Can I use this sealant on concrete surfaces?
Yes, this sealant is designed to provide excellent adhesion to most construction materials, including concrete and timber.
Does this sealant replace structural tapes?
It serves as a superior alternative to tape for complex connection joints and joist ends, providing a more reliable and faster finish.
What is the drying time?
While the surface will set quickly, it is recommended to allow for a full curing period as per the environmental conditions before subjecting it to high-pressure air tests.
Is this product safe to use indoors?
Yes, it is designed for use in residential construction, though always ensure the area is well-ventilated during application.
How many joists can one 600ml sausage cover?
Coverage varies based on the bead size, but a single sausage typically seals approximately 5-8 joist ends depending on the gap width.
What happens if I accidentally get it on my skin?
Wipe away the excess sealant immediately and wash the area thoroughly with soap and water.
Troubleshooting
Sealant is difficult to extrude from the gun.
Ensure the nozzle opening is cut sufficiently wide and check that the plunger mechanism on the applicator is not obstructed.
Sealant is not adhering to the joist surface.
Clean the surface thoroughly to remove construction dust or moisture before reapplying.
Pros and Cons
Pros

- Provides a seamless, long-lasting airtight barrier
- Designed specifically for high-performance construction standards
- Reduces thermal bridging at joist connection points
Cons
- Requires purchase of a dedicated 600ml sausage applicator gun
- Application surface must be clean for optimal adhesion
- Less effective for wide structural gaps compared to foam fillers
Setup, Compatibility & Care
To begin, ensure you have a standard 600ml sausage applicator gun. Loading the sausage is straightforward: cut the end of the sausage casing, insert it into the applicator tube, and screw on the nozzle. Always test the bead size on a scrap piece of timber first.
Before applying the sealant to your structural joints, ensure the surface is free of dust, loose debris, or oils, as these will inhibit the bond. After use, store any remaining unopened sausages in a cool, dry environment away from direct sunlight to maintain the integrity of the chemical composition. Clean your applicator immediately after use with warm soapy water or the manufacturer's recommended solvent to prevent the sealant from hardening inside the nozzle.
