It depends how thick it is applied but figure 15 square inches for 1/4" thickness.
I really like this product; but I suspect it is not what you need. It is not an adhesive. It bonds to itself. It has a relatively thick consistency and is not great for layering.
PC-Woody can be used to fill nail holes and replace with wood screws.
It is but it if you are glueing to pieces of wood together glue is stronger.
Yes. As long as the surface is clean and stiff as wood. It will cover the holes and stay permanently. Good luck.
There are various ways to secure the rocking chair arm but using PC-Woody to surround the dowel will not keep it from working loose without the aid of a screw.
Yes it is sand-able once dried. It is really good s#!t.
This is one of the most awesome wood fillers I have ever used. It is not necessary to fill the hole using layers. I used it several years ago to fill the gaps in some balcony 45 degree corners in 2"x 6" boards. I filled the gap 2" deep and it did not shrink up or crack. I did have to do some sanding on excess product outside the hole, and also applied some additional product in some divits, but it did NOT require additional bonding agent. The repair has lasted years and still going strong and it is in heavy sunlight every day. Another great feature is that the product has a great shelf life. I used it last night and when I opened the 2+ year old container, it acted like it was brand new. LOVE IT, LOVE IT! This is a GREAT product.
I always prime my repairs before applying a finish coat of paint. I feel that this process insures the repair will match the surrounding finish.
Yes it is waterproof. Two part epoxy. I used it to fill not holes in exterior siding.
