Skimming the caulking

[Jamesuk]

We have a proud bit -)) of caulking about 500metre long (when added up) that is about 1-2mm proud.

I'm looking at getting my chisel skills back to School standard and beyond this winter.

Any thoughts?

Plan buy a couple of Stanley fat pocket chisels and the 30degree sharpening tool plus a few other bits and start at the bow working aft.

Good plan?

Cheers

It may be proud due to swelling of planks due to increased moisture content. It may go down if planking dries ou. Has it been this way all summer? Worth checking before you attack it.

fien multimaster is good. An angle grinder and 60 grit paper on it is also good but a bugger to clean up after.

I did the same job on my HR about 10 years ago. The best tool I found, after trying lots, was one of those small craft knives which takes a scalpel blade. The blade is flexible enough to be pressed flat against the deck, and if you run it along at an angle it'll slice the excess caulking off cleanly.

It's really easy: use the back of a VERY sharp chisel, wetted with water & a dash of washing-up liquid. Excess peels off
Like magic. Much easier, safer & better finish than craft blade.

Interesting, chisel didn't work for me. Maybe because HR used a silicone caulking which was very flexible.

That just digs in!

That will depend on who is using it, try upside down

Try one of these. The blades are razor sharp and the handle long enough for you to use it two handed, hold the scraper at a low angle and work the blade side to side ove two or three lines of caulking.

Chisel won't work, unless inverted, v sharp and water a lubricated. If used that way, excess caulking pares off in lovely long (metre-+) strips.

Yes some older HR used the silicone based caulking, i have been told that is more of a big to do and comes off just like the silicone in your bathroom if you have ever removed that. This stuff on the newer HR is not silicone based and skims off easily.

Possibly true - use a scalpel - one of those cheap ones with a lot of removable blades - use the 45 degree one.

BUT WAIT and see if it disappears over the winter, or you'll have a bilge-pumping problem when you go back in again.

Easiest and safest method for removing excess caulking is IMO to use a razor type blade like this:

You wrap it in tape both ends, just leaving 6mm or so centrally on the cutting edges. Let the tape overshoot the sides, to provide you with "handles". Hold it between thumb and index both hands, flat against the deck but slightly bent so that only the cutting part of the edge is in contact. Cut along the seam.

I took about a 1mm of mine all over.

The only tool as far as I'm concerned is a sharp chisel about 1 1/2", wide enough to span the caulking and slide over adjacent planking.

It doesn't take too long but working up wind is easier. My caulking was a Faro 2 pack product laid 23 Years ago, can't comment on any other.

HR use Sea Line 100 described as Alcoxy Silicone Caulking?

Pass, we had a guy onboard who said older HR have but this one does not.

Polyurethane ;-) is what we have and HR use both. Ours is easy to skim with a life on deck of 5-10 years, the Silicone based one is not so easy to skim but will last longer (so i have been told and read)

The manufacturers recommended shelf life of Sea Line 100 is only two months. However, unlike other silicone based caulking I have used, it does not go hard when time expired. As an experiment, I opened an old unused tube of Sea Line 100 with an expiry date of Aug.2010. The contents were still quite soft, but despite Mediterranean temperatures, the stuff did not go off and remained a gooey mess. Working with the in date stuff on my HR, the caulking could be skimmed with a hobby tool blade and sanded after 24hours. Hope this is of interest. Steve.

Yes, interesting, and in line with my experience of using time-expired silicone caulking, which also didn't cure! Filthy mess to clean up!
