Rectorseal 81880 1-poundダクトシール複合

"I used this to seal around the electrical conduit where it enters my house, and it was so easy to work with. It’s like a soft modeling clay that stays pliable, so you can really pack it into gaps to stop drafts and bugs. Unlike spray foam, it’s not messy and you can actually remove or adjust it later if you need to. Great price for a very effective product!"

Product appeared old and was sticky on my hand skin. Finally, after shaping product and leaving it several days to dry, I found product to have hardened, but not hard enough. I could reshape product and it wasn’t a good seal-used around the sides of ducted diffuser. Back to the drawing board. Or, next time you cut your floorboards to install a diffuser for the ducting heating, make sure you know how to use a hacksaw. Try to cut diffuser housing spot-on or you’ll be forced to search for sealants that perform lower tham expected.

This is a unique product. It works well to seal up holes in electrical boxes with wire passing through. Easy to knead and shape. Not sticky to the hands but stays in place very well. Too soon to tell but seems like it will stay pliable and not harden. Bottom line a great product for sealing up those holes in the wall through out the house where plumbing or wire passes through.

Good

In my opinion, a very underutilized form of sealing. I use it around all types of pipes/wires extending through walls, but by no means is it limited to that. Very easy to use, and long lasting.
