Great adhesion

Still one of the best but does lack grab power.
The CT1 Black TRIBRID Multi-Purpose Sealant & Adhesive is a versatile solution for a variety of sealing needs, making it suitable for bathrooms, showers, and windows. This product comes in a convenient two-pack, ensuring you have enough for bigger projects. One of its standout features is its odourless application, which makes it pleasant to work with, especially indoors. Additionally, its anti-mould properties are a significant advantage, providing long-lasting protection in damp environments. The sealant is also waterproof, ensuring that it remains effective in wet areas, and its vibration resistance adds to the durability, making it an excellent choice for areas subject to movement. Its flexible nature allows it to adapt to different surfaces and shapes, making it easy to apply. Each tube contains 290ml of sealant, providing ample product for multiple uses. One of if not the best adhesive sealants available, however lacks instant grab power. great for exterior use!

Great Stuff!
This stuff is the best! I've used it in all sorts of conditions and it's subjected to very high and very low temperatures. It's never failed.

Just what I ordered and on time

This stuff was definitely made in hogwarts.
This could stick Katie Price to her next husband for eternity. Plus it's holds water back like Moses and is easier and more satisfying to apply than my haemorrhoid cream. I used this batch to fix a porcelain tile that came unstuck ("ooo you should use muck and prime slurry"....I did to lay them all but this one lifted and the base is solid so get over it gramps). Great stuff. Just don't lick your fingers to clean it off. It's not nice like 785+.

Works great.
Works good. Wouldn’t say it’s any better than most sealants. You will need to let it set fully.

Brilliant stuff
Wonderful Stuff. Have used the white tubes on the caravan seams and a new roof light. Easy to use. Next job repairing and securing the ridge tiles . Brilliant value.

Herculean stuff
Awesome stuff. Can be messy to use but once it is in/on/wherever you use it, it adheres very strongly and is waterproof

Por fin un producto para todo
Hice una reforma en el lavabo y tenía que fijar con tornillos la parte del grifo a la pared justo en la zona donde pasaban los tubos de agua y tenía miedo que después de la paliza de alicatar la pared y el dinero invertido pudiera pinchar un tubo y liarla parda. Un amigo me recomendó este producto para pegar esa parte y es una maravilla, no es una silicona como tal es un producto mucho más moderno, se limpia superfacil cuando lo pones, lo puedes usar como yo en este caso pero también para sellar juntas contra el agua. Este producto sella y pega hasta debajo del agua, no pierde color como la silicona normal que se pone fea. Pues lo pegué y ya te puedes colgar de hay que no despega es increible la fuerza que hace, es mejor que los tornillos. En fin con esto ya no necesitas nada más, y encima hay colores pocos pero hay. Me queda pendiente sellar la parte de abajo de la cerámica con el plato de ducha para asegurar que no haya filtraciones y además que pasen los años sin que ennegrezca y mantener a raya al molesto moho que en el pasado ponía fea las siliconas. Este es un producto moderno y eficiente también es más caro pero es para siempre así que a mi me vale la pena.
