What to use?

[turkish6]

hello everyone,
My question is what should we use to fill a week spot on our deck. At the foot of our bimini top we have 2 screws. One of the screws does not hold because it is very soft under the deck. After we hauled out this fall we removed the bimini top and cleaned the hole that was rotted. We then dried it out with acetone and it has been left for dry all winter. We are ready to fix it and not sure what we should use. We want to fill it in with something that will allow us to use a plug so that the screw will have something to hold strong to. It is a section about 2" long X 2" deep X 1" wide. So basically we want to fill the gap and as its curing we want to set in a plug so that we get a strong hold. What material should we use. Also cosmetic is not an issue because the foot of the bimini will cover the entire area.

Or we are up for better ideas

thicken epxoy , EPOXYWORKS give this a read, it should help.

If you were to post some pictures, that would greatly help. There is a lot of open ground to flounder around in such a short post.

Is the boat wood? Glass over wood?

Don't use screws, for any significant fastening, in any substrate.
Instead fasten with through-bolts, backing plates (or at least washers), and nuts.

If it is small area then you might try starting again with acetone for a period of 24 hours, then start with penetrating epoxy thinned so you can inject it with a plastic syringe and have it absorbed all round the problem area for a few applications before ending by filling with unthinned epoxy. As Gord notes through bolts will hold better than screws. The screw holes never were properly sealed the first time. Make sure you seal the through bolt holes.

I will take pictures next time I am at the boat.
