Moss Killer Ireland - The Best Solution for the Job

Moss is a pesky plant that if left untreated can cause damage to the structure of any roof. It can also be particularly unpleasant to see if growing on a path, driveway or patio. If you’ve been searching for a way to rid yourself of moss growth across any of these areas, your best bet is to use a trusted moss killer.

There are many home-made remedies out there that claim to eliminate blankets of unwanted moss, but most simply aren’t strong enough. And standard weed killers won’t do much.

Unlike other common plants, moss doesn’t have roots for the movement of water or nutrients. Because of this moss relies heavily on constant moisture, so the key to an effective moss killer is through drying the plant out entirely.

What Happens to Moss, Green Algae and Red Discolouration After I Have Sprayed?

Green algae: In most cases no need to wash after treating once surfaces are exposed to the weather, rain will wash away any traces of dead algae but if desired can be powerwashed after 2 days to remove traces of dead algae.

Red Discolouration: No need to wash kerbs. On houses leave Algae and Fungicidal Remover for 1 week before powerwashing, if there is a trace of Red Discolouration left on walls after washing apply a second treatment when walls are dry and leave, red will disappear over the following days or weeks. In some cases no powerwashing is required.

Moss: When moss goes brown it is dead. Light growth of moss on concrete, and driveways will disappear through time. In most cases it is recommended to brush the dead moss from concrete, driveways and roofs.

Can I Paint After Using Algae and Fungicidal Remover?

The answer is yes. Using Algae and Fungicidal Remover prior to painting removes all traces of Algae which in turn gives  paint greater adhesion to surface.
