Weed and Moss Killer | Special for Courtyards, Paths, Terraces | Ultra-Concentrated 400 ml

SBM Ultra-Concentrated Weed and Moss Killer 400 ml (Reference: PROCOURU400) is the ideal professional solution for keeping your outdoor mineral surfaces in perfect condition. This product from the SBM range combines formidable effectiveness with easy application thanks to its innovative self-dosing bottle. Intended for home users and professionals alike, it is an indispensable ally for maintaining paved, slabbed and concrete areas.

Applications and benefits

This ultra-concentrated weed killer is intended primarily for outdoor mineral surfaces: paved courtyards, gravel paths, slabbed terraces, driveways, parking areas and the surroundings of buildings. It is the optimal solution for homeowners who want to keep their outdoor spaces looking good, as well as for landscape maintenance professionals, property managers and local authorities.

The product's effectiveness shows in its fast contact action on mosses, lichens and weeds less than 10 cm tall. This allows preventive and curative treatment of the unwanted vegetation that spoils the appearance of mineral surfaces and can cause structural damage in the long term. The concentrated formula provides coverage of 177 m² with a single 400 ml bottle, offering excellent value for money for maintaining large areas.

Technical features and innovation

The self-dosing bottle is the key innovation of this SBM product. This patented system allows precise, automatic dosing of the concentrate, avoiding the risk of overdosing or underdosing that would compromise the effectiveness of the treatment. The built-in mechanism makes preparing the spray solution much easier, even for beginners.

The ultra-concentrated formula contains active ingredients selected for their effectiveness on the shallow-rooted plants typical of mineral surfaces. This optimised concentration makes it possible to treat up to 177 m² with just 400 ml of product, considerably reducing treatment costs compared with conventional solutions.

Packaging in a high-density polyethylene bottle ensures optimal preservation of the product for several years, provided the recommended storage conditions are respected. Labelling compliant with European standards guarantees traceability and safe use of the product.

Application method and usage recommendations

Apply the weed killer ideally in dry weather, with no rain forecast in the 6 hours following treatment. The optimal temperature is between 15°C and 25°C to maximise the product's effectiveness. It is best to treat in the morning or late afternoon to avoid rapid evaporation of the solution.

The self-dosing system makes preparation much simpler: just connect the bottle to a standard sprayer and operate the mechanism to obtain the correct dose automatically. The resulting solution should be applied evenly to the areas to be treated, avoiding contact with desirable plants.

For regular maintenance, a preventive treatment is recommended in early spring, followed by spot applications as unwanted vegetation appears. Spraying equipment should be rinsed thoroughly after each use to preserve its performance and avoid any risk of cross-contamination.

Expert tips and getting the best results

To maximise the effectiveness of the treatment, it is advisable to combine the weed killer application with prior mechanical cleaning of heavily overgrown surfaces. Vigorous brushing removes thick moss and improves penetration of the product down to the roots of resistant plants.

Following up with a pressure washer after treatment (48 hours minimum) permanently removes plant residues and restores the original appearance of the surfaces. This technique is particularly effective on natural stone terraces and old paved paths.

For maintenance professionals, it is wise to plan interventions around the growth cycles: main treatment in March-April, a follow-up treatment in June-July if necessary, and a preventive treatment in September-October to prepare for winter. This seasonal approach ensures lasting control of unwanted vegetation.

Avoid these common mistakes: applying in windy weather, which scatters the product; treating wet surfaces, which dilutes the concentration; or spraying too quickly, which results in uneven treatment. Wearing personal protective equipment (gloves, goggles, covering clothing) is essential whenever the product is handled.
