Hey Blokes!

If you have a look at the photo below, I've got some holes in the Kitchen wall (caused by a leaking Shower Recess on the other side...:() that need to be filled with Builder's Bog. Trouble is, they're of a fair size and in a highly visible area. So it's not going to be easy (well, not for me anyway...:cool:) to get a nice un-wavy final surface on them.

The main problem is that the stuff is awfully sticky, and doesn't really like to let-go of anything you use to trowel it on with, except for maybe those small plastic spatula-thingies that they give you with the cans. But they're nowhere near as wide as the holes in question that need to be filled. And if you use something wider - like a short piece of aluminium extrusion as a levelling-spreader - the stuff will stick to it quick-smart, and become almost impossible to remove once dry (which happens pretty quickly...:doh:)

So... My questions to your collective neural knowledge-bases are:

1) Can you buy bigger, wider aftermarket versions of those little plastic scrapers (that they give you with the cans...), that are made out of the same special plastic that seems to more readily "let go" of the Bog - even when it's dry?

2) Has anyone been able to work out a way of "screeding" the stuff to a virtually level finish, by perhaps hitting it at just the right time with the Scraper, which was perhaps first dipped into a can of Turps beforehand?...:?

Any more thoughts about handling the stuff would be greatly appreciated. For what it's worth, I'm probably going to use a 50:50 mix of some of the normal stuff that I've got lying around, added to a small new can of the more "flexible" variety that you can buy now.

By the way, the two little dots that you can see in the middle of each hole are Screws that have been partially driven into small pieces of Ply that I have used as backing-patches to close up the back of each hole in order to enable practical filling with the Bog. You drive the Screws (by only a centimetre or so) into the Ply, and then cut the Ply to the widest size that will fit into the hole. When you can just get the Patch in and out of the hole, you run a bead of Construction Adhesive down the face of the Patch at each end, slip it into the hole, and then pull it forward (with a little bit of wriggling to spread out the glue) against the back face of the VJ boards. The next day, the adhesive should be dry enough to tolerate removal of the Screws. Bog away...

Many Thanks,
Batpig.
