Anti-Fouling Composition

Make an agglutinant by heating together

By weight White lead, ground in oil............... 2 parts

Red lead, dry........ 1 part

Raw linseed oil...... 14 parts

While hot stir in yellow ocher, kaolin, baked clay in powder, or any inert body, such as silica, barytes, gypsum, etc., to form a stiff dough, and, without allowing this compound to become cold (the vessel should not be removed from the source of heat), dilute with more or less manganese linoleate to the required consistency.

Marine Paint to Resist Sea Water

First prepare the water-resisting agglutinant by heating together Dry white lead, carbonate only....... 1 part

Litharge............ 1 part

Linseed oil (fluid measure)......... 14 parts

Heat these and stir until of the consistency of thick glue, and for every 36 parts, by weight, of this compound add 3 parts, by weight, of turpentine, and 1 part, by weight, of mastic varnish (mastic rosin dissolved in turpentine); reheat the whole, and for every 32 parts, by weight, stir in and mix the following:

Baked and powdered clay.............. 4 parts

Portland cement..... 16 parts

Zinc white........... 1 part

Red lead............ 1 part

After well mixing, dilute with more or less turpentine (not exceeding 25 per cent of the whole), or linoleate of manganese, the latter being preferable, as it has greater binding power. For colored paints use red oxide of iron or green oxide of chrome, but do not use chrome green or lead, as they will not stand the action of the sea water.
