UniBond 2079321 Anti-Mould Sealant / White Silicone Sealant for Kitchen and Bathroom / 1 x 147 g Tube

After reading a lot of reviews, I was hesitant to buy this but I needed sealant in a hurry and didn’t want to have to mess around with a gun and tube set up. The package arrived on time and intact and after reading the instructions on the back of the tube, I got to it. The tube is a little hard to squeeze the sealant out of but it’s worth persevering as once it got going, it wasn’t too bad. The sealant itself was pretty thick which was good and it spread easily so it didn’t take me too long to reseal the edges of my shower. The downside is the smell. Reviews here said it was like vinegar but it’s much, much worse, almost like acetone. It may be because I have asthma but I only lasted five minutes before grabbing a face mask to try and ease the sting from the fumes and I still had to take breaks every couple of minutes because my eyes were stinging from it as much as my throat was so I would say if you have sensitivities or asthma, take precautions because you WILL feel it. Once I was done, it was easy enough to smooth it all out and after three hours, I tested their ‘touch dry’ claim by running the shower for ten minutes. The seal held perfectly so I would recommend this sealant for other novices like me.

I bought a tube of this product rather than one of the larger cartridges that require a gun. There are obvious advantages that the tubes have, and unless I needed to apply sealant over a large area in one go, I would choose a tube every time. The cartridges do contain a fair amount of sealant but I nearly always only need a fraction of the contents. The cartridge usually ends up back in the shed and forgotten about, with the contents going off before I ever get around to using it again. The tube is small and neat with a screw lid. Contents will keep for three months (off the top of my head), so if you're doing a series of small areas like I am, you can take your time and use the sealant gradually. The cartridge requires a metal gun cage, but the tube is manually squeezed out. The perfectionists amongst us who don't use silicone sealant regularly will prefer the greater amount of control that the tubes give when applying, particularly around corners where the cumbersome cartridge and gun can make application tricky. I've found that this sealant applies smoothly and is easily wiped up when neatening up the application. It sets within 24 hours to a brilliant white. I have been using it to reapply to internal silicone uPVC window joints which had become unsightly with mould. The areas are always prone to mould staining. The sealant has remained brilliant white since applying. I've ordered a second tube of this stuff because of the convenience of storage and easy application. I don't feel pressured to use all the sealant up quickly and know I can tackle replacing all the old silicone sealant around the house over time. Removing the old sealant is enough of a faff without being on a go-fast to use a whole cartridge off sealant up before it disappears into the shed black hole or sets!!! Good stuff

Good product less hassle with not using the gun. The only drawback is that once opened it has a short expiry date.

This was sufficient sealant to seal one shower basin, It does not require a metal gun by which to apply it. The cut needed at the nozzle to begin applying is marked out with a line as a guide to cutting. A nice help. It takes some effort to squeeze the sealant out, Some strength, and for a few minutes it takes to apply it. The price was good and a known brand. I use masking tape as the online guides advise which I peeled off as soon as I had applied the sealant. Going slowing but not stop and start - and being patient - is the key top a good seal I'd say.

The stuff is great hence I bought it again but something I think is worth noting is that I ordered this on the 22nd or 23rd and it arrived on the 24th December That's pretty efficient and worthy of mention.

This UniBond anti-mould sealant works okay, but it didn’t cover the areas as well as I expected. The application was a bit tricky, and I had to go over it multiple times. It may work better on smaller or smoother surfaces, but overall, I was a bit disappointed.

Needed to reseal around shower cubicle as water was seeping through and damaging ceiling below. Also a cracked and chipped tile. I am not a pro and therefore the finished job isn't quite to professional standards. In fact it does look a bit messy! But, it has worked in sealing the tray. It wasn't as easy to go on as I would have liked, having cut the nozzle, the tube took a lot of heavy squeezing to get the product out. I expected it to flow out but it is quite thick and I found it hard to squeeze without using both hands. I then had to go back and smooth in which I found to be quite messy. Having left it 48hrs I must admit it does seem to be of sturdy quality and probably will last longer than the last paste type sealant I used, that had gone on more easily but when dried looked thin and weak, which is why it probably didn't last long! This I think will hold well even if it does look like an amature has done it!!

Bit tricky at first but works fine once you've got the hang of it. Great for small jobs, especially in an awkward spot.

Used it for fixing 8 ft x 2 inches long granite strips on granite kitchen platform. Made a bead only on one surface (platform) and then pressed the strip. Worked excellent, no leakage. Beware that it dries pretty fast (around 4 minutes) so plan to use accordingly.

Lo recomiendo

no me sirvió de mucho se cayo muy rápido

A superior product, however very expensive for the quantity received

They said that it was Anti-mould , but in 10months it has badly moulded in kitchen area. No difference with regular sealant
