Product Information
Full details
The Sika Plastix-22A Premium Grade Sealant in White is a versatile, neutral-curing silicone sealant ideal for construction and industrial applications like glazing, facades, and roofing. Its key benefit is excellent primerless adhesion to most building materials, offering a durable, waterproof, and UV-resistant seal. A potential consideration is its specific Shore A hardness range, which may not suit all flexibility requirements.

Troubleshooting
Sealant not adhering well
Ensure the substrate is clean, dry, and free from dust, grease, or any contaminants. Re-apply after proper surface preparation.
Sealant remains sticky after application
This can occur in very humid conditions or if the sealant is applied too thickly. Ensure adequate ventilation and allow more time for full cure. Avoid disturbing the joint during curing.
Poor flow from the cartridge
Check that the nozzle is cut to the correct size and that the cartridge seal has been fully removed. Ensure the sealant is within its shelf life and has been stored correctly.
Discoloration after application
While generally UV resistant, certain environmental factors or incompatible substrates could cause minor discoloration over time. Test compatibility on a small area first.
