Need some advice to install my plastic keeper footbraces. I drilled, filled and redrilled the holes. I assume the screws that came with the kit simply screw into the bracket from the outside-in? I would also assume to use some type of silicone to seal the screws? ANy recommendation on what type of silicone and can I get at hardware store? I noticed some holes on the brackets that look they they are meant for a small screw from the inside-out, but I was only given four screws and considering there is very little to screw to, I do not think this is correct? Is this all there is to attaching these braces or am I missing something? I am already commited and want to install the deck tomorrow, so any advice is greatly appreciated!
