soda
Soda is useful as a natural mineral for eliminating moss. It unfolds its effect when cleaning paving stones, concrete and natural stones.
1. The ideal time
Pick a day when there is no rain ahead. Also in the following days there should be no rain, otherwise the effect of this method will be minimized.
2. Preparations
Loosen dense pads of moss with a scraper and remove the remains. Prepare a solution of ten liters of boiling water and 15 to 20 grams of soda.
3. Combat
Spread the mixture on the terrace slabs with a squeegee and let the liquid act for at least five hours. The effects will increase if you wait several days. After the exposure time, remove the moss with a scrubber.
Potassium permanganate
This potassium salt, when dissolved in water, provides an effective moss control agent for limestone and natural stones such as granite or marble.
1. Make a solution
Heat ten liters of water to boiling point and mix in 15 grams of potassium permanganate. Wear gloves when mixing and stirring. The mixture turns brownish to purple in color.
2. Check the effect
Test in a visible place whether the agent is suitable for the subsurface. Potassium permanganate causes discoloration on light-colored stones. The agent is unsuitable for wood.
3. Combat
Pour the solution onto the patio slabs. The exposure time is at least five hours. Then scrub the panels with plenty of water and rinse with clean water.
Kärcher
An effective way to remove moss is with an industrial vacuum that can vacuum dry material as well as water. This measure is suitable for any surface and is particularly effective when the moss is soaked with water. Remove the bag and leave the filter in the device. Move the nozzle directly over the areas covered with moss. The large negative pressure pulls the cushions off the panels. Then fill empty joints with sand.
