Does Staining On The Outside Stop Mildew?

Regular cleaning with a deck cleaner is essential to prevent mold and mildew from infiltrating your deck. Applying a mold-resistant deck stain or sealer, which combines trans-oxide pigments or mildewcides, can help combat this issue. Gutters collect decaying leaves and small twigs, making them natural breeding grounds for mold and mildew. Decomposing debris in gutters can clog downspouts and cause water to run over the edge of the gutter, which drips down your home’s siding, spreading the mildew to other areas.

To combat mildew growth on your exterior, you should identify and dry out moisture sources, expose objects to sunlight, clean the mildew, monitor humidity levels, use air purifiers, and improve ventilation. Powdery mildew, which is white or gray and appears in splotches, can turn yellow, brown, or black as the fungus continues to grow. If mold and mildew return, apply an outdoor mold remover like Wet and Forget to your siding and trim to keep the outside of your house mold and mildew-free.

Maintain your siding annually with a mild detergent solution and inspect your siding regularly for signs of mildew growth. Brush off any surface growth outdoors to prevent scattering the mildew spores in the house. Sun and air fabrics thoroughly, and if any mildew spots remain, treat them with a product like Cabot® Solid Color Acrylic Stain + Sealer.

Re-route water away from your home, making sure your roof has an air conditioner. Water-based stains are extremely resistant to mold and are easier to clean and maintain.
