Coal Tar Epoxy

[PEEJAYSEA]

Can anyone point me in the direction of where to buy VC (?) Coal Tar Epoxy paint?

This has been recommended to me for painting the inside of a steel hull.

Very good cheap book on the subject to download..

Personally I go for this stuff for the initial primer holding coat. http://www.promain.co.uk/product/PPG_SigmaCover_640_Sealer_Amerlock_Sealer_id3900

If you want to search the forums then google is better -

Slight mix of name here. It is VC Tar from International.
Not sure this is an ideal product for painting inside a steel hull as it is very low build. If you are looking for a fine finished surface it may be what you want but if you are looking for good protection that will be covered by furniture and linings there are better products. On interior steel you are normally looking for long life over a well prepared surface. That means high film build will be quicker and less labour intensive. Interprotect (also International) is probably better or the equivalents from Hempel, Teamac, Jotun etc. With VC Tar it will be particularly difficult to get adequate thickness on seams, stiffeners etc and these are the bits where coating will break down first.
Most chandlers will sell a selection of the right products. If the surface area is big enough a commercial chandlers will probably be quite a bit cheaper but you will need to be able to use the bigger tins quickly enough to avoid wastage.

I believe that the old coal tar epoxy was withdrawn on health and safety grounds, as it contained some aromatics deemed to be dangerous. I used it a long time ago to good effect. Its replacement is called VC Tar, a shadow of its former self.

At one time I had the standard for paint systems for certain offshore platforms. The main requirements were grit blasting to SA 2.5 standard, needlegunning where not possible. Several coats of high-build epoxy primer followed by a couple of epoxy top coats. You might be able to dispense with the top coat inside the hull. Conachair's second link looks like the right stuff. Or look at Rustoleum on the same site, which may be even better.

Many thanks for the excellent advice and pointers. It gives me something to get my teeth into over the long winter months!

Whatever you use, the important stage is the prep. As Vyv says SA2.5 all over, no short cuts on corners/welds etc or your expensive paint system will be compromised.

Actually it is a two pack now called VC Tar 2
http://www.boatpaint.co.uk/datasheets/International/Product Data Sheets/VC Tar2_GB.pdf

When I recoated my hull the original protection was called VC Tar epoxy, but as Vyv says they had to change the spec and it's not exactly the same.

Strange thing was when I talked to International paints as to the best new protection their recommendation was to go for Gelshield 200 coatings.

Also I agree with others on steel you should shot blast to SA 2.5 and also recommend you talk to International paints as their technical department is most helpfull.

I have been using Epoxy Mastic from http://Rust.co.uk on my steel ketch with excellent results.
Their FE123 rust converter is very good too as it does not need the excess washing off.

The Epoxy mastic has been left uncoated* on various places on the topside and side decks with no problems.
*deliberately - to see how Scottish weather and UV affected it.

As the name suggests, it is quite viscous (syrupy) and therefore does not sag away from edges but this also gives rise to its one disadvantage. It doesn't self level / flow out even on a horizontal surface so don't expect a mirror flat finish.

I'd recommend you try a can. Mixing ratio isn't critical - I just mix as much as I need and it sets down to 5C.

You should be able to get it from any chandlery specialising in canal narrow boats - it's the black stuff they paint the hulls with.
