Mildew

Hi there,

I live in the Bahamas. A couple of years ago my father painted the siding of our house using latex paint and we are expecting to repaint soon. What do you recommend we do as it is mildewing? This is a very big problem.

Mildew grows where the conditions suit. The right combination of surface chalk or dirt, moisture, and temperature will allow it to grow.

To remove it, wash the surface with a solution of bleach 25% in water with a bit of tide. The bleach will kill the mildew and the tide will wash it off. Wet the surface with the solution, let sit for about 5 minutes, then rinse. Wet any nearby plants beforehand and rinse afterwards.

Use this to wash your house annually, and it will look nice for many years.

Once the mildew is removed you will be ready to paint.

Hope this helps.

There are some additives for paint that are supposed to prevent mildew. I don't know how effective they are.

Latex or alkyd paint on the exterior - latex is better suited for exterior applications because it is flexible when dry and allows moisture to transpire through the film to reduce any problems from moisture behind the film.

Periodically washing the exterior of the house will keep the mildew at bay and keep the paint looking fresh for many years.

Hope this helps.

Mildew

Paint with mildewcides may help minimize mildew for a while. As indicated, keeping surface clean is most helpful. Cut back overhanging branches and thin trees to allow more sunlight and ventilation. Cut back or remove overgrown shrubs. Mildew spores are everywhere in the air. They tend to settle in on damp, shady, poorly ventilated surfaces. If the sun does not shine on this side of the house until afternoon, it stays wet longer, and this side of the house will need more frequent cleaning.
