What kind of hot glue gun are you using?
I have two glue guns but the glue always melts the depron.

Those tiny hot glue guns from walmart. They are low temp hot glue guns and take the small glue sticks. The glue gun is literally $2. It looks like it's meant for a kid to use. Those are fine to use on depron. You may get some heat marks, but not outright melting from it.

Hi Guys

I see that you have done a fair amount of research on glues .What is the consensus at this time .

Is there a UHU that we could get from England that is equivelant to the UHU that we have been using ?

what thickness epp should I use? I'm making a 25 size parkflyer type cub. Would 7mm thick foam do the fuselage alright?

Customer support,

I would like to inquire about the following product. I have been using the Welders industrial strength contact adhesive that is packaged in a red tube. The product was readily available at Wal-Mart, but recently it has been very difficult to locate. A search of the Homax website showed Welders glue in a grey or silver tube. The question, are these two products the same and just packaged different? I have attached images of the two products.

Best regards,


The response from Homax:


You are correct! The first picture was the older look and now the welder is available in the silver tube. You can usually locate this at Lowes stores.

Please let me know if you have any further questions.

I have noticed at my local Wal-marts that welder has gone off the shelves. There are now a variety of Loctite brand adhesives. I just made a test hinge from the Loctite "Stik N' Seal - Original - Waterproof adhesive". It seemed to be a little thinner than welder, but is also toluene based, dries clear, and makes a similar hinge. It's only been an hour and it feels pretty tough. Full cure should be nice and strong I think. Anyway, this seems to be the alternative to welder that is now available at wally world.

Edit: After about 6 hours or so, it seems very strong, and in fact might be superior to the strength of the welder hinge. It is certainly on par with it. It also seems to dry a little faster at the beginning, which will speed up builds. I'll use it on my next airframe and see how that goes overall. However, for now it seems we may have a viable alternative to welder.

Yep, it would. So does goop, welder, and any other toluene based adhesive. A small amount leaves a big crater in FFF or the thicker blue foams used in homebuilding. Depron will also melt with them. They are great on EPP though and are the best glues for that material. Although, hot glue has the convenience factor to it.

Cheap exacto blades

The best way to ensure great cuts in EPP is to use sharp knives. Hobby City has these blades for less than 10 cents each!

Thumbs up for RCFOAM

I know y'all have heard of this place to get your foam and they are the best, however not many know of this "other" , cheaper foam they have called CellFoam

They state on the website that its characteristics is very similar to depron...and they are accurate. I tried it (all kinds of glues, cutting, sanding)and except for a very minute difference in finish, could not tell any difference.

My opinion...would save money and get same results.

here is link to bulk packs...and there is a $2 sample pack you can get to try it.This company has exceptional quality and always gives you a worthwhile "freebie"

I really like the Depron they have as well. Very high quality.

I'm making a separate post about comparison of Depron to the Hobby Lobby FoamCore board (peeled)...something I just discovered.

I have ordered some batteries and a couple large boat esc's from them and I have had good luck with it. Similar to hobby city, just not the selection. All I have used are some of their very small batteries (2s 200mah) and they have worked well so far. Order a bunch of stuff and let us know

I can never quite stand to constantly throw away blades, so I just keep a sharpener handy. A few swipes every few cuts keeps the cuts nice and clean.
