problem: roofed and from three sides enclosed pool area. ceiling boards (painted cement boards) show development of black fungus/mildew despite of area being force-ventilated.

a fungicide additive is Tetrachloroisophthalonitrile but i have no idea where to buy and what ratio to mix with paint.

any advice appreciated.

I seem to recall that Nippon Paint & TOA brands have a product with the addative for anti fungus mixed into their acrylic emulsion style paints.

I used them on the exterior brick work of my factory five years ago & no fungus or rot whatsoever.

Can't remember the products off hand, however, any large paint shop should be able steer you in the right direction.

I used Nippon paint and sealer.Very good and looks very nice.They have acrylic as well as oil.

"Nippon"

thanks a lot Soundman and Mellow. my builder provided me today with the Nippon specsheet which says "fungus resistant". i will give it a shot.
