Question: Do I need to use the entire contents of the tank at once, or could I use half one day and the other half a few weeks later?
Document: This kit was exactly what I expected. It contained enough product to finish my job in my basement as expected. Easy to use. No problems with clogging. I ordered the product when it was cold and submerged in hot water for a couple of hours to warm it up. This may have helped the yield. There was no way to tell if the product inside the tank was at the correct temperature. Very satifisfied.
The only glitch I ran into was that the plastic nozzles came packed in the bottom of one of the containers and only two survived intact enough to use. This almost delayed my project, but I was able to tape two cracked nozzles together and finish the job with them. I recommend you order an additional set of nozzles just I case.The room I sprayed was roughly 20 x 20 feet. It was of open stud walls.
Being a dedicated and independent DIY'er, I really like this spray foam product. Bear in mind that it is a serious tool, not a toy. You need to be careful and plan your work. Take special care to ventilate the work area and protect yourself and others by reading the safety sheets. If you have Building Codes in your town, you might want to talk to them before ordering and using this product, just to be sure you won't run into problems with codes.This is an excellent product.
The foam begins to expand immediately, so you can see if it's working. After the initial spray, I cleaned the gun as the instructions said and put the old nozzle back onto the gun for temporary storage until I can use the rest of the foam in the crawl space. Instructions say it will store for up to 30 days, but I'll only wait long enough to get some new nozzles in hand.When you plan your spray, keep  in mind several small but important techniques.
After clearing the area to allow maximum maneuvering in both directions of the 15 foot (approx.) hose and shaking the bottles for at least 30 seconds, I started spraying. Even though I was new at this, the You-Tube videos and the knowledge of what the &#34;pros&#34; had left me, helped to get the knack of spraying down fairly quickly.
(My floors were not yet finished.) Foam that expands beyond the studs can be sawed flush with a hand saw or a serrated flat bladed knife. With a little planning, this product will work well for you.I used the fire retardant version of closed cell foam. The results were as good (in appearance and effect) as what I paid much more for from the professionals I hired previously.
Having used &#34;professional&#34; foam insulation companies at least twice in the recent past, I decided to try my hand at spraying foam. The product came in two fairly heavy metal containers similar to propane gas bottles - about 60 lbs each. The hose and some sketchy instructions also came inside. What the user must provide are the protective items - coveralls, respirator, gloves and eye protection.
Keep first application down to about an inch thick - come back around for a second coat to get it thicker. Clear your workspace - if you stop spraying longer than about 30 seconds the nozzle will clog and you'll have to replace it before going on. Keep fresh nozzles strategically placed along the spray route. Cover the floors below the spaces where the stud bays are located, because there was a lot of foam dropping from the nozzle. This may have been because my nozzle was cracked.
Answer: no
