Which surfaces can I use Sodium Percarbonate on?

You can use Sodium Percarbonate to kill moss anywhere! From Block Paving to Tarmac, Indian Sand Stone, Wood, Roof Tiles, all Tennis Courts including artificial surfaces, Patios, Fences (spray only), Decks, Brickwork and Concrete. In fact anywhere you have moss or algae.

Why does Sodium Percarbonate work so well as a moss killer?

Once sodium percarbonate comes into contact with water, it causes a reaction which produces copious amounts of oxygen. This breaks down the very fine single roots called rhizoids, cutting off the plant’s support system.

How does it prevent Moss from returning?

In order to reproduce, moss produces spores. These single-celled organisms break off and are spread by wind or water. Sodium Percarbonate is brilliant at killing single celled organisms.

Why does it not kill other plants?

Sodium Percarbonate only affects single celled structures like bacteria, fungi and algae. Plants are multicelled.

Is it safe?

Yes. Sodium percarbonate breaks down into oxygen and water. In fact sodium percarbonate is the main ingredient in Vanish stain remover.  Keep away from the eyes and remember, when wet it can be an irritant to the skin.
