Thread: Replacing roof hatches

It'll probably need to have any rivets drilled out first, and you may find the old silicone will just break away. If not, a good box cutter type knife and cut around all the edges as best you can. It will need to have a fairly long blade as a "Stanley knife" blade will probably be too short to get in far enough.
When it's out, the best way of removing the old silicone will be to lightly wire brush, as in a drill type. This will give you speed, but don't put a lot of pressure on it, otherwise you'll do damage to the surfaces.

Hope this helps.

What about one of those green nylon scourers?

Yeah you could use one of those if you like Mick, but I would think it'll be a very long tiring process. Now if you had one that fits a drill

They do. I'm sure GG uses one. I think I've seen them in Bunnings.

Your a bit sneaky making sure your little lights off

Yes, Bunnings do sell them, and they will work well too, they just don't last as long as steel or brass brushes. We go through heaps at work cleaning down, so the steel jobs are what we use here.

Well, there's usually no one at home anyway, or so I am told.

How'd you go with this Pedro, all good?

Pushy!!!
