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.

I have a window that has a small gap. Mosquitoes would come in from there. Got this produce to fill that gap. Never have I used anything code to something like this. So I was a complete noob. If you are one, this might help you what to expect. The product does what it says. You point and spray, after some time the foam hardens. I would suggest to plan ahead. This thing comes like a shaving foam but STICKS. The first time I used it I had no Idea what i was doing and just showed pointing the gap. It EXPANDS. In matter of minutes it was a mess. So spray ONLY of the nozzle fits the gap! Another thing I did was, spray the thing on waste paper or something and let it harden. This it could cut and mould into whatever shape I wanted and filled it in smaller gaps. Other things to keep in mind. This thing is STICKY. DONT LET IT TOUCH YOUR SKIN OR SURFACES YOU DONT WANT IT ON. (From experience). Its not like you can't get it off but it is just too much work. The spray is not continuous. You need to get used to it.

The product PU is good but the dispensor has problem. I fixed the gun with the delivery tube on the dispensor. It is annoying to find that PU comes out of the delivery tube but also from the junction between the gun and the dispensor can. That messes up everything. For some reason it builds pressure in the delivery tube. Inspite of the plastic cap screw provided with the dispensor to close the delivery tube, PU oozes a little and appears to get hardened inside the delivery tube. The item is NON RETURNABLE and messy. It appears the quality of the gun and its sealing with the can have poor quality seal.

It is a nice product, when I saw negative reviews I had a doubt but want to try. Perfect solution for gap filling. Only thing is need to follow procedure properly. 100%satisfied. I ordered more numbers.

Giving 3 because its not as beneficial as you think it it. The delivery was fine, product intact and easy to assemble. Ensure the spray mechanism is locked as shown in the picture. Before every use, shake it vigorously and first few seconds you may hear just the air pass through, later on the liquid which transforms to foam will come out. Now this is usable only where the gap you want to fill is very big, thats also mentioned on the product as big gaps, see the pic. Now if the gaps are so big , one could as well fill with cheaper options like cement mix. It does not work well for small gaps or holes. After it is sprayed leave it for 2-3 hrs to solidify and form the foam Use gloves and avoid touching it as it sticks to skin like fevicol but its mote difficult to remove. Overall I feel this can be used only when the gap or hole is really big, but then same can be acheived with cement.

This sealant provides a robust and long-lasting seal that I can always rely on. The application is smooth and easy, even for intricate projects. It cures quickly and forms a strong bond, resisting weathering and movement exceptionally well. I've used this product on various materials, and it consistently delivers excellent results. I highly recommend this sealant for any filling. The only thing you have to be careful is with your hand if the foam touches the skin it's very sticky and we have to peel it off. USE GLOVES FOR THE APPLICATION

Very good product

Good filining

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

This foam works great and it expands in a real significant way, so you don't need to use too much. It's all fairly self explanatory and it works down to 20 degrees, which I thought was shocking. I believe caulk only works down to 40, so it's handy it functions in sub freezing environments. A word of warning. It's exceptionally sticky and it can expand...unpredictably. If you're using it any place that may be overhead, use caution until it's done curing.

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

Great stuff. Used with copper mesh to prevent pack rats, easy to apply. No harsh fume smell. Great value.

Works well and gives plenty of coverage. It expands more than you expect, so it’s better to fill a bit less than you think because it keeps growing before it sets. Mine has already cured and I’ll be using an oscillating tool to cut it clean. The only drawback is that you have to keep the can upside down, which can be awkward depending on what you’re trying to fill. Overall, a reliable option for sealing bigger gaps.
