1k Assembly Premium Polyurethane Foam Sealant: 750ml of light yellow goodness. Ideal for sealing windows, tiles, doors, and AC gaps. Optimal insulation solution. PACK OF 1

Pretty easy to use; a lot of reviews have said it's difficult to fill holes, or is very messy or hard to control, but I'm very much not a handy person and I had no trouble at all. I overfilled holes a little since it does slowly expand and ends up spilling out, but once it's dry it can be easily cut with a stanley knife or sanded, so that wasn't a problem. I used it to fill gaps around pipes to keep mice out, and a larger amount to fill in a missing panel from some boxed-in pipes and a missing section of cornice. For the latter I sanded it down roughly to shape, filled in gaps with caulk, and intend to simply layer on some plaster or polyfill and then paint over the top. The only thing which got me was that when it's wet, the stuff is very sticky. I wasn't initially sure whether it was trimmable when completely dry or I had to scrape excess off while still setting, and when I tried to scrape excess off with a putty knife before it finished setting, it stuck to the tool in such a way that nothing could remove it and then caused sufficient damage to make me throw the putty knife out. From what I've read you need a special solvent to remove the residue.

It is good w.r.t quality. Have to use in one shot otherwise the nozzle is blocked after first use because of the foam is hardened in the nozzle. Be planned before opening it.

Meant for single use. Cannot be stored for reuse. If planning to reuse, then buy "ICFS Polyurethane PU Foam and Dispensing Gun Cleaner" (available in amazon for INR499) to clean it after usage. Strictly Use Hand Gloves and place some old news paper sheets underneath when using. because it spills all over and it is not easy to clean. Direction for use: Use a little and wait till it expands very well , and then reapply if required. Always use some sticks or skewer sticks to clean the nozzle tube immediately after usage. if not cleaned, then leftover foam in the tube hardens and clogs it . cannot be used latter, has to be thrown

Nice product. It has solved my purpose. Got with good packing. There is transperent straw attachment so look carefully in bubble wrap. There is no picture but I have filled gap between furniture and wall. Low density but ok to filling gap. I am recommending most to purchase. One time use.

I received only bottel, no attachment with this bottle. How I will use. Please help

Serves the Purpose, but 750ml was too much for my usage. Couldn't use it fully. Use gloves to avoid sticking it in your hands. Use thinner or turpentine to wash it immediately. One time usage only, hence plan your areas well in advance before using it. Happy with the Purchase.

Clear instruction on its application. Easy to use and can be cut to finish with a sharp blade. Similar to thermocol and it is full weather proof. Used it to seal uneven gaps between the aluminium mosquito nets and the concrete walls. Buying it again for use in other balcony and also to seal the hole made for split AC installation. Great product.

As many others have written - it is impossible to use this over time. this means, if you don't have multiple openings/areas to seal, do not bother buying. I had one small AC piping hole in the wall that i needed to seal and i followed instructions to the T. It went very well. And then, i put aside the can with 90%of the material still in the can. The can however, continued emitting the foam....it is now 2 days and the can continues hissing and emitting foam. Therefore, the conclusion is that the nozzle is defective in many of the pieces and therefore when the pressing of the applicator is released, the nozzle seems to be stuck and continues emitting foam. What an ENORMOUS WASTE OF MATERIAL!! besides the agony i went through seeing that polyeurethane foam all over the floor.
