CRC 14077 – Frequently Asked Questions

1) Will CRC minimal expansion foam sealant blow my window and door frames out of square?
No. The 14077 foam is a low expansion formula that expands only 50 percent once fully cured, which is why it's the right choice around window and door frames where a high expansion foam can bow a jamb before you've had a chance to shim it. Fill the gap, let it cure, and trim. It's the same reason it works for tight penetrations where you don't want the foam pushing on conduit or pipe.
2) Can I use expanding foam to seal electrical and HVAC penetrations through a wall?
That's a listed application for the CRC 14077 polyurethane foam sealant, along with plumbing penetrations and HVAC system penetrations. The controlled 50 percent expansion matters here: you're sealing an annular space around a conduit or duct, and a high expansion product will keep growing after you walk away. Note this is a general sealing and insulating foam, not a firestop product, so for a rated assembly you want a dedicated firestop sealant instead.
3) Can CRC minimal expansion foam be painted or sanded after it cures?
Yes, all three. Cured 14077 foam can be sanded flush, then painted or stained, so it can be finished into a trim detail or a visible reveal rather than left as raw foam. Worth knowing before you cut in: the cured foam is amber, so it will read through a thin coat of light paint unless you sand it back and prime.
4) What is the difference between low expansion and regular expanding foam for a property manager doing turnovers?
Expansion rate is the whole decision. High expansion foam is for filling large voids where nothing can be distorted, like a stud bay or a crawl gap. Low expansion, like the CRC 14077 at 50 percent, is what you use anywhere the surrounding material can move: window and door frames, around conduit and pipe, tight penetrations. On a unit turnover where you're sealing around a replacement window or an old plumbing chase, low expansion is the safer default because it will not bow a jamb or crush flexible tubing.
5) How big is a can of CRC 14077 foam sealant and what does it weigh?
The can measures 8.06 inches by 2.19 inches by 2.19 inches and weighs 1.08 lbs. That's a standard single-hand straw-applicator can size, so it fits a normal gun holster or a bag pocket. Useful if you're buying by the case for a punch list and need to know what a box of them takes up on the truck.
6) Does CRC 14077 foam sealant meet VOC rules for a jobsite in a regulated state?
The 14077 carries a VOC consumer product definition value of 2.9. If your spec or your local air district sets a VOC ceiling on sealants, that's the number to check it against. The product is made in the United States.
7) How do I order the right CRC minimal expansion foam, is there more than one version?
There's one to order: CRC part number 14077, the minimal expansion polyurethane foam sealant. No finish, size, or formula options to specify, so a reorder for a facility or a distributor line item is a straight repeat of that part number.
