Review: A Good Sealant - Used to seal a double glazed UPVC window frame and brick wall. Easy to apply, good adhesion and gap filling. Cured ok in lowish outside temperature. Looks a good finish. Dowsil is a reliable manufacturer.
Review: Excellent adhesion - I've used this for a variety of outdoor sealing tasks, it bonds very well to brick, mortar and uPVC. It also works great indoors as well, especially where regular acetoxy have trouble bonding to paints, and it has no strong odour which is good plus when using inside. A couple of words of warning however: 1) This stuff is thicker and tackier than your regular sealant and will make an absolute mess if you're not careful. 2) Although it is white as described, it's not the same brilliant white you'll get with a normal acetoxy silicone, I would describe this as a very slight beige-grey tint

## Questions & Answers

**Q: I need to seal around an inset kitchen sink. Tried wickes clear and it goes white when wet. Will this do the job for me?**
A: Yes... good stuff for that or Sunday poly is also very good... different colours. . White is the most popular.

**Q: Does it stick glass**
A: I used this product to craete a seal round an outdoor 1 metre square manhole 'drain cover' over a year ago and  it has not 'degraded' at all since it was applied.  I might be wrong, but I would be fairly confident that it would stick glass pretty well. Care would be needed to avoid 'smearing' the glass tho' as it is very 'smeary and sticky Black rubbery stuff'.  Good Luck.

**Q: Would this stick a rubber seal to a runner for bifold doors?**
A: I’m not sure, I used it to seal around my sink area. I don’t even know if it’s waterproof but it works and is still there a year later .

**Q: Is this okay to use with leds?**
A: Hi, it shouldn't be a problem to use with leds.
