Which Selleys glass sealant do you need, and how do you choose?
Selleys glass sealants are reliable, weather-resistant sealing solutions designed specifically for glass surfaces — windows, mirrors and similar. Two products sit under this path, and the choice between them is straightforward: one is the general glass silicone, and the other is the trade product with a specified chemistry and finish.
The thing worth knowing before you buy is that glass sealing is a case where the cure chemistry matters, not just the performance claim. The trade product in this section is explicitly a 100% neutral cure silicone, and that specification is the reason to reach for it where the glazing sits in a frame whose material you cannot afford to have an acidic sealant working on while it cures.
What this category covers
The product listing on the live category page is loaded dynamically and could not be captured, so this page is built from the two products the live sitemap lists under this path, plus one genuinely glass-relevant sealant from elsewhere in the sealants range.
How to choose
General glass and window frame sealing
Selleys Glass Silicone delivers a long-lasting, waterproof seal for glass and window frames, giving protection against harsh weather conditions. It is the general-purpose choice for glazing work where you want a durable weather seal.
Trade work, and where finish matters
Selleys Pro Trade Glass Silicone is a 100% neutral cure silicone with excellent weather and UV resistance and a matte finish.
Three things in that description are decision-relevant. Neutral cure means the silicone does not release acid as it cures, which removes a compatibility question around the frame and surrounding materials. UV resistance matters because a glazing bead is, by definition, in the light — a sealant that is watertight but not UV stable hardens, chalks and eventually cracks along the line where the sun hits it hardest. And a matte finish reads differently from a glossy one against a powder-coated or painted frame: matte sits quietly, gloss catches the light and draws the eye to the joint.
If you want a crystal-clear finish
Selleys All Clear sits in the multi-purpose range but is described as giving a crystal-clear finish and suiting windows, showers and other glass surfaces with a water-tight seal. It is the one to compare when invisibility of the bead is the priority.
The products in this range
- Selleys Glass Silicone — a long-lasting, waterproof seal for glass and window frames, with protection against harsh weather.
- Selleys Pro Trade Glass Silicone — 100% neutral cure silicone with excellent weather and UV resistance and a matte finish.
Common questions
What is the difference between the two glass silicones?
Pro Trade Glass Silicone is specified as a 100% neutral cure silicone with excellent weather and UV resistance and a matte finish. Glass Silicone is described more generally as giving a long-lasting, waterproof seal for glass and window frames with protection against harsh weather.
Why does neutral cure matter?
A neutral cure silicone does not release acid while it cures, which removes a compatibility question about the frame and the materials surrounding the glazing. Pro Trade Glass Silicone is the product in this section specified that way.
Which one should I use on an aluminium window frame?
The sources behind this page do not list substrate compatibility for either product, so check the individual product page before you buy. Where a neutral cure is required, Pro Trade Glass Silicone is the one that states it.
Will the sealant survive direct sun?
Pro Trade Glass Silicone is described as having excellent weather and UV resistance, and Glass Silicone as protecting against harsh weather conditions.
What if I want the bead to be invisible?
Look at Selleys All Clear, described as giving a crystal-clear finish on windows, showers and other glass surfaces.
Can I use a glass silicone in a shower?
Wet areas have their own range, formulated against mould and fungus growth. Start at wet area silicone for shower recesses and bathrooms rather than assuming a glazing product will suit.
Can I use these on a mirror?
The category is described as covering windows, mirrors and more. A mirror's silvered backing is sensitive to the wrong chemistry, so check the individual product page for a stated position on mirrors before applying anything to one.
Where do I find the rest of the sealant range?
Under sealants, which also covers wet area, roofing, construction, fire-rated and multi-purpose products.
