UniBond Outdoor Window and Door Frame Sealant, Premium Silicone Sealant Suitable for Use on Various Materials*, Waterproof and Weather Resistant, White, 1 x 392g Cartridge

Great sealant as described. Fast delivery. All good!

The sealant was delivered in standard Amazon 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.

Tackling outdoor sealing tasks around brickwork can often be a messy job, but this EVO-STIK Window & Door Frame Sealant shown in ⁠my photo makes the entire process incredibly straightforward. I bought this cartridge specifically to seal along the bottom threshold of an external uPVC door frame, and the consistency of the paste is spot-on. It flows evenly from the cartridge gun nozzle without requiring excessive force, yet it is thick enough that it won't run or sag. It is remarkably easy to smooth down into a clean, low-profile bead using a damp tool, filling the uneven gaps seamlessly between the concrete floor and the uPVC trim as seen in my photo. The adhesion properties of this formula are exceptional. It grabs tightly onto porous concrete, rough brickwork, and smooth plastic or metal surfaces without requiring any special priming beforehand. Once fully dry, it forms an entirely waterproof, draft-proof barrier at the base of the door that handles expansion and contraction wonderfully. Because it remains flexible rather than drying completely brittle, it easily accommodates the natural shifting and slight movement that occurs with temperature changes over the seasons, resisting cracking and pulling away over time. With a 290ml cartridge providing excellent coverage, this tube offers fantastic value for a quick household maintenance project. The fact that it contains an integrated fungicide to actively combat unsightly mould growth is a massive plus for damp outdoor locations, and the ability to overpaint it once cured allows you to blend the line seamlessly into your surrounding masonry if needed. Backed by a robust 15-year lifespan rating, it provides immense peace of mind that your repairs are built to last, making it a well-deserved five-star product.

This product is instantly waterproof which is great, I used this to seal around my PVC door frame, and so far it works great, quick drying time was 30 minutes, it didn't seal properly the first time I tried it, so I had to use a finger trowel second time worked wonders

Just like there products easy to use and reasonable price

The sealant is good. In a standard tube for use with a tube gun. The finish has stayed bright white since application. So all good.

Dose exactly what it says on the tin. Bright white - quality product - nice finish with a quick drying time - overall good value

Needed to fill some gaps between external UPVC window frame and brick wall. Product arrived promptly- thank you Amazon. The product consistency is quite runny for a filler which took some getting used to. That said, it was great at filling the gap deeply. On the drying side, it has been drying for a week and not fully dry. Doesn’t matter to me as not painting but might be a consideration if you are in a hurry.

Be', non c'è che dire, un silicone sigillante per serramenti che riesce davvero a sigillare anche i più piccoli fori tra la cornice e il vetro. Fluido a sufficienza da uscire alla perfezione dall'apposita pistola, sigilla la finestra a prova di spifferi!

Sigillante per esterni di altissima qualità. Nulla a che vedere con saratoga o affini. Dopo un anno dell'installazione il prodotto è perfetto e non accumola polvere. Un po' caro ma ottimo
