Process for the manufacture of a paint which has the special feature of being insecticidal. One starts with weighing component 1, water and placing it in a rapid disperser B to which a cellulose thickener 2 is added; a dispersant 3, a universal antifoaming agent 4 and a 10% solution of decalcifier, standing for 10 minutes. After this rutile titanium dioxide 6, a talc 7 and a calcium carbonate 8 are added and dispersed at 1000 rpm for 20 minutes. Finally an acrylic copolymer in aqueous solution 9, a glycol 10, a pine oil 11, an aliphatic naphtha 13 and a pyrethroid derivative 13 are added, and all this is allowed to stand as a dispersion for five minutes. The quantities of these components for obtaining one kilogram of paint are: component 1 from a minimum of 180 g to a maximum of 240 g, component 2 from 2 to 4 g, component 3 from 2 to 4 g, component 4 from 2 to 4 g, component 5 from 10 to 20 g, component 6 from 100 to 150 g, component 7 from 30 to 50 g, component 8 from 440 to 330 g, component 9 from 200 to 110 g, component 10 from 10 to 20 g, component 11 from 1 to 8 g, component 12 from 3 to 20 g, component 13 from 20 to 40 g.
