Applying Litespan covering

Hi folks, I have a question.
I'm building a small dlg glider with an open structure wing. I know there are lots of choices how to cover it. I have found litespan covering in my workshop, which I believe would be perfect for this but I don't have balsaloc. It's a substance designed for this covering that works like glue. My question is, is there any other way I could apply this? Dope comes in mind but litespan is fully sealed material with no heat sensitive adhesive. Are there any alternatives?

Plain white wood glue....works almost like Balsaloc. If you spread it thinly on the frame and let it dry you can then use heat just like you do with Balsaloc.

Thanks Steve
Wow, I never thought of that. Is it really going to stick even after you let the pva glue dry? I never thought you can re-activate its stickiness by heat. I might try that on a piece of scrap. Good tip

I've used it quite few times with Litespan and other stuff and it's always held fine.

BTW this is one of the few cases where plain old PVA seems to work better than the fancy new aliphatic wood glues .

I definitely understood that Balsaloc has a base of white glue (here in Italy is tipically known with commercial name of "Vinavil").
I used white glue diluted with some water.
Water hepls white glue to better soak the wood. I recently built a Slingsby Skylark by WestWings covering it with litespan and white glue with water. Even if you see the balsaloc tin, inside it there was white glue + water.

Or you can use a foam brush and 'paint' the back of the litespan and then apply it like any other covering film.

I also use white glue. I like plain Elmers. I do not recommend the cheaper no name brands and stay away fron the kid or school safe versions (they are 'safe' to eat ).

I use Balsaloc and would think that it isn't made from ordinary PVA because it is quite difficult to remove from the sole of your covering iron and also from your fingers (PVA simply peels off). It dries as a very thin, transparant, flexible plastic coating.

A little messy but it works really well though. I've never had covering come loose when using Balsaloc although I haven't tried PVA for the same job.

Here are more options/discussion of replacements for Balsaloc/Balsarite:

I found the Modge Podge, readily available at craft stores, works well.

My caution with thinned pva is the water distorting balsa sheeting; probably on sticks would be fine.

good luck

I would not thin the white glue if applying it to the frame work.

I also second Modge Podge as a good alternative to white glue. IIRC it is also a little more resistant to moisture.

Wow, I always used Elmers white glue, diluted 50/50 with water, to apply Japanese tissue to free flight planes.

I wonder if you could paint the frame of a FF model with diluted white glue, let it dry, and iron on the Japanese tissue with a trim iron or adjustable heat soldering iron?
