Code Product
ha5285 Hempinol Black Bitumen Varnish 4L.
– (delivery free if exceeds of £100) – maybe if enough people want, it may prove feasible for someone to order, you can get foc delivery. Cost for a 4L tin for @ £21.99
can dilute with cheap white spirit, however it is a thin coat hence name suggests “varnish” as opposed to using commercial antifoul which we all know is excessive cost.
4 litre tin does 2 coats on my boat, I add Copper powder to 2nd coat ~ 500g stirred into this final coat. I get this from ebay @ ~£13.00 inc delivery.
I find it gives good protection to hull, keels etc.
I find if there is any barnacles or weed at end of season this falls off readily with a quick pressure wash.

I have used this brand for 5-8 yrs find it does job!
Preparation is everything as always.
