FAQs
Is this sealant paintable?
Generally, silicone-based sealants like the Ulti-Mate are not designed to be painted over, as paint will not adhere to the silicone surface.
Can I use this for aquarium construction?
This product is designed for construction and glazing; it is not intended for the assembly of aquariums or constant underwater immersion.
How long does it take to fully cure?
While it skins over in 5 minutes, full cure time depends on the bead size and environmental conditions, typically taking 24-48 hours for deep joints.
Is it safe to use on natural stone?
Neutral cure silicones are generally safe, but always test a small, inconspicuous area first to ensure no surface staining occurs.
What is the best way to remove uncured sealant?
Uncured sealant can be wiped away with a dry cloth or a solvent-based cleaner such as white spirit.
Does it have a strong odor?
As a neutral cure silicone, it has a much lower odor profile compared to acidic or acetoxy-cure silicone sealants.
Troubleshooting
Sealant is difficult to extrude from the cartridge
Check if the nozzle opening is too small or if the sealant has begun to cure in the tip. Ensure the gun mechanism is functioning correctly.
Sealant is not adhering to the surface
The surface was likely contaminated with grease, moisture, or dust. Clean the area thoroughly with a solvent, allow to dry completely, and reapply.
Sealant skinning over too quickly
The ambient temperature may be very high. Work in smaller sections to ensure you can complete the tooling process within the 5-minute window.

Setup, Compatibility & Care
Preparation: Ensure all joint surfaces are free from dust, grease, oil, and loose debris. Clean the area with an appropriate solvent if necessary and ensure it is completely dry.
Application: Cut the nozzle of the EU3 cartridge to the desired bead size. Insert the cartridge into a standard sealant gun.
Tooling: Apply the sealant firmly into the joint. Use a smoothing tool or gloved finger to finish the joint within 5 minutes.
Compatibility: Compatible with concrete, glass, metal, timber, and ceramics. Not suitable for applications where constant water immersion or heavy abrasion occurs.
Storage: Store in a cool, dry place and ensure the nozzle is sealed if partially used to prevent curing inside the tube.
