Blacking coverage

[Paul C]

I know its probably been answered lots of times before, but its expensive stuff so I don't want to over-order! How much blacking does a 45ft narrowboat typically need? The stuff we're going to use, for compatibility with the existing, is Interzone 954. I've looked at the datasheet online and it suggests, using a 500 micron layer, it will be 1.70m2/litre. A rough calculation on a 45ft narrowboat, and allowing for a bit of extra (I used 800mm for the side height, 2x45ft and 2x 7 foot for the side lengths and ends, but I know it being pointy at the front and curved at the back will slightly reduce the area), shows that 14.9 litres is needed. Given its about £170/5 litres, its worth a double check!

PS forgot to post the link: http://www.international-pc.com/PDS/2589-P-eng-A4.pdf for the paint's datasheet.

Are you painting the base plate or just sides? And is there any reason you are choosing to use such an expensive product?

 

Sorry just noticed your using epoxy

Just the sides. The boat is already painted in it, if we switched paint we'd need to gritblast the boat.
