LOCTITE Insulating Foam Sealant 
Description: Loctite TITE FOAM is a new generation of polyurethane-based insulating foam sealant that
expands to fill, seal and insulate gaps & cracks inside or out. It is a white polymer foam based on purified
& concentrated ingredients that provides 4x more density vs conventional foams for better durability &
insulation. It is easy to use and apply with its attached straw applicator and provides a quick durable seal
from the elements. Loctite TITE FOAM Insulating Foam Sealant has excellent adhesion on most building
materials like wood, concrete, stone, metal etc. Product does not contain CFC-propellants.
Available As:
Item # Size Color
1988753 12 fl oz (340 g) White
Features & Benefits:  4x more density vs conventional foams for better durability & insulation
 Seals out drafts, moisture and pests
 UV resistance reduces foam brittleness and darkening*
 Strong adhesion while providing flexibility to move with building materials
 Applies soft and cures rigid with a bright white color
 Indoor & outdoor safe
 Tack Free in 8 minutes, Trims in 50-70 minutes
 Sandable & Paintable
Recommended For: Loctite TITE FOAM is suitable for interior and exterior projects. It has excellent adhesion to most building materials including
wood, metal, stone, brick and PVC. Use for filling gaps and cracks and sealing around wiring and plumbing penetrations, HVAC
ductwork, basement and crawlspace drafts, sill plate & rim joists, attic hatches, under baseboards, gas line penetrations and
outside water faucets. Can also be used to sealing out drafts and moisture as well as keeping out pests and bugs.
For Best Results:  TITE FOAM is not a fire stopping material and SHOULD NOT be used in areas that require fireproof or fire stopping materials
 Despite significantly higher UV resistance, it is still recommended to protect the foam from UV radiation. Exposed foam
should be coated with a protective covering or coating
 Do not store product on its side
 Does not bond polyethylene, polytetrafluoroethylene (PTFE)/Teflon® or siliconized surfaces
 For cold weather application, product should be stored at room temperature at least 12 hours before application
 In dry conditions, it is recommended to fill gaps in several layers by application of smaller foam strings (up to 2 inches
thickness)
Coverage: For a 12 oz (340 g) can:
 A 3/8” (9.5 mm) bead size will deliver approximately 134 ft (41.1 m) of foam
Note: Yields shown are based on theoretical calculations, for comparison purposes, and will vary depending on ambient
conditions and particular application.

If you don’t use all of your spray foam you can use acetone to clean out the spray nozzle and the tube that screws onto the can you can also use golden grain alcohol which is 190 proof to clean off the foam if it’s stuck to your hands or in the nozzle for reuse

Hey, great!! I wanted to know which was likely more sticky. Part of my situation requires to foam to stay bonded to cement board. Stay put like construction adhesive, basically.

I see a few here declaring Loctite is the more sticky.

That works for meh!!!

[arrowdog]

I've used both. I prefer Loctite in visible locations because it stays white and looks better, and it also seems to adhere better. Great Stuff comes out yellow, but after a year it will look hideous because it turns dark-orange as it ages. The cans must be inverted during use, otherwise the propellant is wasted; don't pause for more than a few seconds or it will clog. I wish Loctite would produce a "pro" kit with a professional spray-gun and cans for larger projects such as sealing rim joists, etc.

[blissjoy]

Thank you. That specifically addressed my "gap" in understanding of how the two products differ. I read on the loctite website that their product also has flexibility which should help with building movement (exterior corner/seam application this would matter.) Your demo did not address this, but I think the smaller pores in the cut foam suggests less worry about breaking free since overall integrity of the loctite appears more uniform.

[HabAnagarek]

I've used Loctite a few times and like it, but it is messy to work with (an advantage, I suppose, as it sticks to almost anything). I've also used the windows/doors version on a small application and it worked fine. When I put the window trim on, any overfill compressed easily. I plan to use it to seal around foam board in my basement rim sill boxes, rather than Great Stuff, due to Loctite's density and UV resistance. I used the regular version to fill big gaps around ductwork going into my crawlspace. That worked, though I used almost the whole can (didn't know the big gap version existed. Oh well.)

[mwest]

Bought the Loctite thinking I would save a buck. Same size can and it does nto nearly provide as much coverage. The can specifically states it does nto have voids. I found huge voids in the locktite. Going back to great Stuff.

[jakemarlow]

Thanks for the short and sweet informative video!

[fgsharp]

Should really have tested the great stuff gaps and cracks as that is a more apples to apples comparison with the loctite.

[sylviagm]

Thanks! Good demonstration. I wanted to see it working. I have to go with the Loctite mostly because Great Stuff can't be used in closed spaces which is what I need. Hope it works to fill gaps under a toilet flange, between cast iron pipe and the concrete floor.

[PongGod]

Word to the wise... wear some old work or disposable gloves before using this stuff. If you get that crap on your hands, it's hard as hell to get it off.

[goldeneye]

The nozzle broke before start 🤕 now how can I start using it ? Never used before 🤔

[PETERJOHN]

I wonder if Great Stuff would be better at sound proofing due to its more porous composition? I want to try this stuff on a wall clock that ticks too loudly, there is an open area around the gear box where the foam could provide an insulating buffer.

[vashon]

Does it matter if it is sprayed with can right side up or upside down? Thought someone said latter is better, keeping gas from escaping. But see both in vids.

[marcmacchiaverna]

Suggestion on what to use around an attic storage area where a side of the chimney comes through? And what sort of ventilation requirements do these products have?

[bryanutility]

Can 4” of lock tight support a person walking on it?

[CF-ewqi]

Hi, maybe you could answer a question. I'm working on a project. I want to make a boat/kayak out of dense styrofoam. But I am having a problem finding the right glue that 1)adheres to styrofoam 2) waterproof. Would this either of these foam insulation products work for my project. Thank you.

[ME-hjnz]

hey, actually I was looking to see if anyone has tested the adhesive strength.. I did quick test, nothing formal. a 2x2 foot piece of ply, and great stuffed it to a section of roof.. i'm getting I put about 45 lbs of lift on the board before I started hearing some give. I'm re-layering a roof on my trailer.. it was spray foamed years ago, but it's starting to leak.. So without great details, I'm using about 2.5 cans per 4x8 sheet of OSB, creating another layer on the roof, that I can tar paper/roll to make it leak proof.

[DrWenChannel]

I have the same conclusion as well. I also found the Loctite TITE is less sticky than the Great Stuff (super sticky and difficult to clean if you got it on your hand)...

[mr-totte]

The great stuff did not cure properly, that's why it's yellowish, it should be cream colored. It needs moisture from air to cure, that's why you are only supposed to use it for small gaps and cracks, not for cavities. When it doesn't cure properly it produces flammable vapors, could be dangerous. Great Stuff specifically says not to use for wall cavities.

[MadTrollGaming]

How much more dense is the loctite? Is it very significant?
