What is polyurethane foam insulation?
It is polyurethane that has been expanded with air when liquid, and formed into sheets, often 2-3 inches thick.
What is foam made of?
Goats make them raw, liquid polyurethane
How do you clean scott's liquid gold off wood surface to prep for polyurethane?
murphy's soap should do the trick
What is the shelf life of Polyurethane Finish unopened?
Polyurethane is a very tough Plastic and is solid at room temperature so the shelf life, at room temperature, Liquid form, still a long time, for furthur answers and for further Elaboration consult The New MrSpock (Xbox Live Gamertag).
How can you remove stains or blemishes from a polyurethane watch?
You can remove stains or blemishes from a polyurethane watch by scrubbing it with a wet terrycloth that has been dipped in a solution of warm water and liquid dish soap. For tough stains, dip a melamine foam sponge into the solution, ring out and wipe the watch gently. Dry well with a clean towel.
Is gorilla glue the same thing as super glue?
No, they are totally different. Gorilla Glue is a polyurethane (basically a kind of sticky liquid rubber) and Super glue is a cyanoacrylate.
How do you install rigid insulation?
Cut panels of rigid insulation slightly smaller than openings. Fill in gaps around rigid panels with liquid nails or any brand of construction adhesive caulking that is compatible with stryrofoam (polystyrene) or polyurethane foam, depending on what type of rigid foam you purchased. I prefer polyurethane foam and seal the perimeter edges with Great Stuff spray foam or DAP latex spray foams. That way you don't have any heat leaks around the edges of the rigid foam even if the rigid panel is between warped rafters or studs.
Can I use Water based polyurethane over flat wall paint?
No. Poly and paint are incompatible. Instead use liquid floor wax. It's easier to work with and will give you a longer lasting surface that doesn't stick to paPer when wet. You can continue to re coat for maintenance. Great for tabletops shelves or painted floors.
Can you spray paint polyurethane foam?
Spray polyurethane foam is a plastic spray that is installed as a liquid then expands many times its original size. It is used in a variety of uses including roofing, air barriers, and insulation of commercial and residential buildings. It is also used to insulate freezers, walk in coolers, and produce storage rooms. Polyurethane has also been used to increase the structural strength of wings in airplanes.
What is liquid nails adhesive made of?
Liquid nail is made of epoxy which is a type of adhesive - - - - - There are epoxies on the market, but Liquid Nails construction adhesive isn't one of them. I looked at the Material Safety Data Sheet for Liquid Nails Heavy-Duty Construction Adhesive. It contains four basic things: a resin to make it stick together, and they don't tell you WHAT resin but it ain't epoxy (because epoxy contains epoxides and polyamines which would have to be listed on the MSDS as they are hazardous in their own right, and they're not on the Liquid Nails MSDS); ground-up stone to make it thick; titanium dioxide to make it whiter than it would otherwise be; and seven different petroleum-based solvents. The other kind of construction adhesive is polyurethane, which contains a modified diisocyanate and a modified polyol (modified so they can be mixed together and packaged in a tube without hardening; when they're exposed to the atmosphere they harden), and probably also the ground-up rock because uncured PUR is the consistency of honey--not what carpenters are expecting to see in their construction adhesive. And since this question is also in the Makeup category...the glue for fingernails is cyanoacrylate-based superglue.
What is the shelf life of Polyurethane Finish?
Officially, 6 months after opening. I have found finishes to be very expensive and shelf life is very important, I use a product called "Bloxygen", it contains an inert gas (Argon) that lays on top of your polyurethane not allowing oxygen in, thus extending the shelf life of your opened can of poly. In practice, polyurethanes will slowly polymerize in the can, forming a globby layer of cured poly, and slowly thickening the liquid poly underneath. I have not had any problems with chipping through the cured layer and using the remaining viscous product. Eventually (after several years in an opened can) it becomes difficult to even spread the thickened coating onto wood, contains unsightly bits of solid cured material, and I suspect it won't penetrate wood as well, but it does seem to dry and cure properly. That's all with an open can. Unopened, solvent-based coatings like polyurethane have a quite exceptional shelf life. I have used decades-old rusty sealed cans of polyurethane, and they appear indistinguishable from current production!
How do you remove polyurethane off of wood floors?
Be careful with this one. If it is thin-laminate wood flooring, you should NOT remove the coating. Check with someone first. If its solid wood, get a decent brand of liquid stripper from the hardware store, follow all instructions and you should do just fine.
