Consumables - Caulking and Seam Fillers
Oakum
There are many types of Oakums. For all types of Marine work the following
are stocked.
Superior Oakum
This is the best that is available. Made from NEW Best Hemp. It is clean from knots and yarns, is long stranded and has no lumps or ends of old sacking. Rolls out a treat. This oakum
is soaked in Tar Oil. This is a tree oil that is distilled from Pine Trees (You call it Stockholm Tar). In fact there are around 26 different Tar oils and the farther north one goes the better the quality. Of course most of us refer to this as Stockholm Tar. After being soaked in Tar oil the oakum is then spun out in a centrifuge.
Supplied in 20 kilo bales. Samples on request.
20 kg bale £139.00  2 kg Skein £24.00
Caulking Cotton
A far better quality and lovely soft Caulking Cotton like we used to enjoy.
1/2 Kilo Balls (8 ply i.e. 8 strands) £4
1/2 Kilo Balls (5 ply i.e. 5 strands) £4
"This Cotton is the finest money can buy and takes us back to the quality of years ago. Highly Recommended"
After long testing on my own boat I can recommend the following.
SIS 440 DECK SEAM COMPOUND (Black)
For many years now I along with many of you have used Marineflex, Sikaflex Purflex etc to name just a few.
Having had wooden boats for over 60 years I have seen the ravages Ultra Violet light can cause. UV has a tendancy to harden products like these over time and then they crack and break down so allowing the bond between deck seam and product to fail and let fresh water in.
Although I am "Traditional" I have to keep up with modern technology so I have now taken on this deck seam product in place of Marineflex.
What is the difference? First SIS 440 is USA made. Its far softer than other seam compounds which in my opinion will stand UV for a much longer period. It is not Isocyanite (such as Sikaflex) or Polyurethane (such as Marineflex) It is a completely different product and as such does not need a primer like others. Simple to use, fits standard skeleton guns, cures in 48 hours. I am doing the complete new deck of my own boat which is in Pitch Pine. The covering boards and around the tops of the frames which come up through are already done as with capping the bulwarks I would have been unable to get at the caulking seams.
The product is much softer than others and it is easy to gun in.Shelf life is 18 months !!
Sold in standard 190 ml cartridges at £10.50 per cartridge
Also in 600ml sausages to fit skeleton gun
600 ml sausage £17.50
All plus carriage & VAT.
BEDDING COMPOUND
This is a purpose made compound for any bedding. It will not go hard but always remain soft and pliable and watertight. Sold in 380cc tubes to fit a skeleton gun. Colour grey only.
If the beading between the cabin sides and the deck on my own boat had used this product I would have saved the cost of major remedial work. The product the shipwright used was incorrect in that after 5 years it dried out and so let the fresh water in. This Bedding Compound will NEVER EVER do that and after 20 years it will still be soft, watertight and pliable. Again the right product to use
per tube
£7.50
T.B.S. No 3 Black Pudding Mix
This is an old and well proven fairing compound for use below the waterline as a substitute for lead based stopping. We make and supply this special formula to which cement powder is added until the mixture achieves the consistency of a stiff bread dough.
It WILL NOT go hard as one would think but remain flexible in the seam for many years. After hardening up the caulking or renewing it, prime direct from the can into the seam and leave for an hour or so. Then either trowel or gun into the seam. Fair off with a stiff pallet knife dipping it in either linseed oil or white spirit. Black Pudding will remain on the soft side so flexing with working seams and butts. In my 50 odd years with wooden boats, experience has shown me that there is to my knowledge no other product with the ability to adhere to wet timber making it ideal for working with between tides.
I know from my own experience having had to rake out a garboard seam, recaulk, fair and antifoul with one eye often looking over my shoulder at the making tide. Modern isocyanites cannot do this unless primed and applied to dry timber. Black Pudding is a derivitive of Coal Tar to which other ingredients are added to stop the cement going hard. Fair the seams with Black Pudding and relaunch within 2 weeks.
May we suggest Metaclor C.R. Primer. This primer is made with chlorinated rubber (C.R) and is an excellent waterproof barrier. 2 coats then anti-foul. (see under Paints >> Antifoul. )
5 Ltr £47.50
Lead Based Consumables
White Lead Paste
For use above the waterline so that it does not contaminate paint colour, i.e. showing tramlines through the paint. However with modern paints such as METACLOR C.R. Primers two coats of this and it hides just about anything from my own experience. The mix is usually 60% White lead with 40% putty added to make it go further. When you have a good ball mixed add a thumb nail of motor grease and mix in well. This will slow down the drying of the putty that gives the cracks
one sees in old seams.
3 Kilo tub £39 (25kg £225.00)
Red Lead Powder
For mixing in with linseed oil putty and stopping seams below the water line. Again a small amount of motor grease added will help.
3 Kilo tin £38
Red Lead Putty
2.5 Kilo tin £24
5 Kilo tin £29.50
All plus carriage.
Can be used straight from the tin/keg with a pallet knife into the seam. If when finished "fairing in" dip a clean pallet knife in Linseed oil and work back the other way. It will iron out any little holes and leave it like a babys bum ready for the primer paint
To those of you using this for the first time fair/sand your hull FIRST and then when "fair" apply Red Lead Putty Do NOT sand over. When the seams are done apply lightly a coat of primer paint to seal and then you may undercoat and Gloss paint.
