Supex: Different Types of Adhesive & Their Uses

Best Glass Glue / Adhesive

Glass glue is is used to bond a unique substrate that can prove challenging to bond. When working with glass, you’re not often working with load-bearing seams. Instead, you’re likely completing a project that must hold up to regular environmental changes with a bond that remains invisible and flawless all the while.

Therefore,the adhesive you use to bond glass to either itself or another substrate must be carefully thought out. You want it to be strong enough to create a water-tight bond, flexible enough not to snap under multi-directional pressures and clear enough to not be easily seen—even years into the future. 

We’re here to help you learn from our years of trials with glass and all the different kinds of glass sealants & adhesives you can use to secure it.

Glass Glue: Bonding & Sealing FAQs

Does silicone sealant stick to glass?
Silicone sealants create versatile & long lasting bond with many substrates including glass, metal, wood, concrete, FRP, plastics ( Except PP, HDPE, LDPE, Teflon) 
Can you put sealant over old sealant?

Never apply new silicone sealant over old sealant as, in most cases, the old sealant would have fallen away or split meaning that, no matter how much new sealant you apply, the leak will persist. Not to mention, applying a new sealant over old will look incredibly messy and unappealing 

What happens if silicone sealant gets wet before it cures?
If Silicone sealant gets wet before it cures, then the moisture cannot evaporate quickly. This can extend the time taken by the sealant to dry up. In some instances, it may also become difficult to achieve proper adhesion. Too much moisture can also lead to the growth of mould and mildew.
How long do you need to leave silicone sealant to dry?
Generally speaking, most silicone sealants take about 24 hours to cure completely. After this point they can be safely exposed to water, moisture, and other conditions of normal use. It is important to mention, however, that a few factors can influence curing time.
