How to Control Moss, Algae & Mold around Your Property

Your Guide to a Safer, Cleaner Property This Winter

Winter’s damp, shady conditions are the perfect breeding ground for moss, algae, and mold. You’ll spot it creeping across driveways, decks, roofs, fences—and even in parts of your lawn. Not only does it look messy, but it can also cause damage and become dangerously slippery underfoot.

Here’s how to get on top of it using SpraySmart Moss & Mold Killer, available right here at Sprayshop.

1. Know What You’re Dealing With

Before spraying, it helps to understand what’s growing:

• Moss: Thick, spongey green clumps—common on roofs, paths, and shady lawns.

• Algae: Slimy green or black film—often on concrete, timber, or damp areas.

• Mold: White, grey, or black patches—seen on fences, walls, and garden structures.

All three can be treated the same way—with a targeted moss and mold killer.

3. Application Tips

• Spray on a dry, calm day (no rain for 6–12 hours after spraying)

• Apply generously to fully wet the surface

• No rinsing or scrubbing—just spray and walk away

• Visible results in 7–10 days, with continued action over time

• For heavy growth, a second application 4–6 weeks later may be needed

4. For Moss in Lawns

SpraySmart is great for hard surfaces, but for moss in lawns, use a product like iron sulphate or a lawn-specific moss killer. We can help you choose the right one depending on your grass type and area.

5. Prevent Future Growth

Once you’ve got it under control, here’s how to stop it coming back:

• Trim trees and bushes to let more sunlight through

• Clear leaves and debris from paths, decks, and gutters

• Ensure good drainage—water pooling feeds moss and algae

• Reapply SpraySmart once a year as a preventative spray
