Loctite Tite Foam PU sealant(White), Expanding Foam for large gaps filling, keeps dust and pests aways, DIY dries fast, waterproof no shrinkage | PVC pipe bathroom, AC ducts 340g | Polyurethane

It’s a very good product for filling gaps. The foam settles down as some type of thermocol after drying. It can be used for split AC pipes holes in place of white cement. Also for gaps in windows and doors for keeping the insects out. But use the product carefully, as it expands after few minutes. You might end up wasting some of it while trying to fill the entire gap/hole with the foam. It’s better to put small quantity of foam in the gap/hole and let it expand. Then use it again if required. Be very very careful while using it. Use gloves. And Avoid it sticking to anywhere on the body, specially hairs on the head, facial hairs, hands and legs. It’s very difficult to remove after, might have to cut hairs too. And it's good if you use the entire Can in one go. Saving it for later is little difficult, as the nozzle and its discharge pipe gets clogged.

It's a good DIY item for home purpose. However it's slightly difficult for the first times to operate. First about effectivess, quite good as it closes the gap quite well. I had 3 inch gaonin my ac vent which I got it closes using this. Working wise, its bit difficult as the handle pump wasn't working so I replaced the order with a new one. The second was working fine. Always follow the instruction and use the bottle upside down . The nozzle needs to be cleaned after use else it will block the way. Waterproofing is good as well.

The best choice for sealing gaps and areas where water or cooling can go through. It's quite easy to use - just push the head onto the bottle head until you hear a click. Shake for around a minute and squeeze the trigger until you hear a hissing sound. The foam comes out malleable and quite sticky, hence the gloves. You can spread the foam into tight corners using a spreading tool so nothing goes to waste, making this a quite versatile product.

The product is totally mess. The foam sprayed mechanism did not work for a single time. It worked for a single time but not through the pipe but it leaked from its nosal point and totally wasted the material. I request don't handle it with your hand I repeat again because if it once get stuck in your fingers or nails it will take 5 to 7 days to remove it naturally and if you will remove it forcefully also then it will not be removed from your hand so kindly used gloves if you want to purchase this item. Kindly insure that the spray mechanism is working properly if it is not then don't try to do anything forcefully because if it once get leaked from nozzle point then it's wasted. In my case the product totally wasted.

Product is very good but equipment is bad quality. After use this spray straw and their triger is breaking and spray leakage

Really does the job. For those who don't know, there's a small cap blocking the inner valve. Have to remove that with a plier before inserting the spray lock. And spray only a small amount because it spreads covering the whole gap.

Very good product

I bought it to close the air conditioner hole in the wall and I was positively surprised about this product. Not only its easy to use, it also perfectly sealed the hole. I should have applied a bit less foam as it expands in around 15-20 minutes. Only regret is the quantity was too low, but likely because I used it too much. One til: use hand gloves while using it, it gets very sticky on fingers

Foam is denser than Lepage or great stuff. Fixed a creaking vinyl bath tub installation.

Cuidado, es un producto que puede no funcionar y luego para buscar el reembolso/sustitución es un una pesadilla tratar con el proveedor y con Amazon

Las espumas están caducadas

Even with cap it did not work on later use

It works great....if you get it on your hands or clothes it's very difficult to get off...Try and wash any excess as soon as you can!!!
