Frequently Asked Questions & Answers

2-In-1 Moss & Algae Killer is a fast-acting moss, algae, and lichen killer. On wood, concrete, and asphalt, a single application will control moss and algae for several months to one year. It will not stain concrete, pavement, stucco or wood.

This product may be applied to lawns and ornamental gardens, around and on homes and other buildings, and home greenhouses.

It may also be applied to roofs; cedar shakes and composition shingles; cedar siding; stucco; cedar, redwood and CCA-treated wood decks and fences; brick, stone and concrete walkways, sidewalks and driveways; growing containers; other structural surfaces; hardened bark of trees; bark mulch; pavement; gravel; patios; asphalt; automobile exteriors; and the exteriors of motor homes and boats.

2-In-1 Moss & Algae Killer may be applied at any time of the year.

Best results are obtained with actively growing moss in the spring or fall. During warmer weather, apply late in the day.

After application, the moss will quickly turn yellow and then brown. Unless the moss is physically removed, it may remain where it died until removed naturally by wind or rain.
