Works on almost all waterproof surfaces, such as: Natural stone, ideal for (mineral) plaster and clinker facade and for cleaning roofs, wood and benches (natural, without oil or varnish), teak garden furniture (natural) and much more. Apply first to a test surface
Each litre yields up to 61 litres of ready-to-use solution and covers up to 900 m² (applied with the garden spray gun). May vary depending on the surface
Due to its very high concentration, application of the cleaner is best carried out using a pressure washer. Ideal for large spaces. Requires less effort than a garden spray gun.
