Review: Good quality - has worked well for my windows and hasnt moved yet
Review: Probably 3.5 stars here... some good, some not so! - The sealant was delivered in standard desertcart box, no packing but came with attached nozzle unlike some other reviews. I had a few jobs that needed to be done both external and internal around the house. The majority of the work was on wooden window frames, but I also used on UPVC front door and some smaller jobs on plaster. The first point of note is that the tube had a expiry date of May 25 so less than than 12 months which wasn't an issue for me as I plan to use the majority on first use but I was surprised by such a short date here. The next point of concern was the viscosity of the sealant itself, it is quite thin (again as mentioned by other reviewers). This on applying can be a benefit as it flows exceptionally well and goes in to all gaps, crevices with great ease. However to my annoyance it does seem to run off the gun much to easily causing some more mess and a small amount of product wastage. A more experienced applicator may be able to work it better than me, but I found I was wiping excess of the gun on a regular basis. I did take a picture so show this excess for reference. After application the appearance looks good, excellent flow as mentioned and a very clean white look. The drying is also not as fast as I hoped, it was still quite soft and pliable after 1-2 hours so please take this in to consideration - my conditions was a warm dry day at 20C. It states 24 hours through dry and this seems to be the case in good conditions. Overall I am going to give 4 stars, as it does look good when finished, as in the heading I probably would have given 3.5, as it was one of the most expensive sealants but as it is on highly visible external windows I wanted it to last! Whether it does, and does not discolour or crack then will inivitably determine how happy I am. Time will tell... and I will review if anything changes, the company states lifetime guarantee on the tube, lets hope they are right.

## Questions & Answers

**Q: Is sealent good for outside around windows frame on stone wall**
A: It works perfectly to seal wood or upvc windows to brick or stone, just make sure its dry

**Q: Can it be painted?**
A: This can't be painted - the label does state that it is NOT paintable. However, the way this is presented may not be 100% clear (I had to read it twice to check).

**Q: What heat can it withstand?**
A: I cannot tell you the exact heat, but I can say I have used it outside for my double glazed windows for some years,  and it is still perfect through hot and cold weather. With regard to exact heat, I am sure the manufacturer will be able to advise you.

**Q: Is this the same as wood putty. I need to fill gaps/cracks in external window frames-will this be ok?**
A: It will be fine, I use in on my greenhouse, on the outside where I have some polycarbonate in the door, which is plastic and wood and it is great, so I can imagine that it will be just as good on upvc and wood or just upvc and glass.  I think you will be pleased with the result.
