Stixall versus CT1 (The Comparison)

CT1 and Stixall are relatively common to compare. Both great product for sealing things, but just how close together are they? Here is our breakdown.

What is CT1 adhesive?

A universal adhesive, CT1 replaces all kinds of adhesives, sealants, and butyl rubber sealants in construction, engineering, roofing, repair, maintenance, installation, and marine repair. Metals, glass, wood, tiles, concrete, synthetic materials, and plastics all stick to it.

Usually used in large infrastructure projects, CT1 can also be painted after it’s fully cured.

CT1 comes in 290ml recyclable cartridges. Store at room temperature, cut the cartridge and nozzle to desired dimensions, apply with a mastic gun on a clean surface, and finish off with MULTISOLVE.

What is SIKA / Everbuild Stixall?

It’s a one-part sealant and adhesive that combines silicone and polyurethane. You can use it to bond and seal most building surfaces, including perimeter pointing around doors and windows, bonding mirrors, jointing cladding panels, and applications that need chemical resistance and high performance.

Besides having a high initial grab and bonding strength, it’s waterproof and weatherproof, quick-curing, and overpaintable, and has great primerless adhesion to many surfaces. CE and UKCA mark it to EN15651-1: 2012, Type F INT.

What is shelf like on both?

Stixall has a shelf life of 12 months (290ml) while CT1 has a shelf life of 18 months. Thus, if you’re looking to go longer, use CT1.
