Thanks for the help.
I am starting to think the material underneath is OSB but it simply looks black from the darco or something.
I also learned how bringing the slide in and out wears away at the protective coating/material and thus exposes the OSB, then causing it to get wet.
Apparently there are "skis" sold to wrap the edges of the slide made out of plastic. I guess it acts as a wear layer for the friction of the slide going in and out and also acts as a drip cap in way creating a 4" or so barrier underneath for the water to drip off.
I guess there is no way for the manufacturer to install a flexible drip cap that compresses when the slide is brought in.
Or maybe, as in my other post, they can make the bottom some type of plastic sheet instead of the **** OSB!!!
Idiots.
Thanks,
iso
