Why Choose 
Guard Anti-M 24?

Why Choose
Guard Anti-M 24?

Curative & Preventative


Guard Anti-M 24 is a preventive and curative treatment with a long-lasting action. It will kill off biofilms and organic growths right down to the roots and inhibit regrowth for up to 3 years.

​ ​Curative:

    • Guard Anti-M 24 destroys all parasitic vegetation, which is then washed away by the rain or simply brushed off.

​ ​Preventive:

    • The active ingredients of Guard Anti-M 24 are fixed into the substrate. They limit the proliferation of mould and make it more difficult for parasitic plants to germinate.

A Safe Alternative


Guard Anti-M 24 does not contain chlorine or organic solvents. It is a safer alternative to harsh chemical cleaners like acid, bleach and alkaline cleaners. Such chemicals can do significant damage to the materials being cleaned and to the user. Guard Anti-M 24 is harmless to treated surfaces, and will not alter the natural look of the material.

However, Guard Anti-M 24 is still a biocide. It needs to kill off biofilms after all. All biocides should be used with care. Before using, always read the label and the product information. Care should be taken to ensure overspray does not fall onto garden plants or into ponds containing fish.

Slow but Effective


Please note that Guard Anti-M 24 is a slow acting but long lasting treatment. If you need something cleaned instantly use Guard Wash instead. The treatment will kill off the biofilm but the residuals still need to be physically removed either by brushing them off or through natural weathering by the elements. How quickly or slowly this happens depends on inclement weather and at which time of year the product is applied. The effects of the treatment are usually noticeable within 2 weeks and will continue to improve throughout the first year.

Its slow action is actually the secret to how thorough it is at completely killing biofilms and from stopping them coming back. When biofilms are exposed to harsh chemicals the outer layers die back rapidly and this creates a crust that protects the underlying growths from being exposed to the chemicals. Unless you physically remove these crusts and reapply chemical, multiple times, the organism as a whole survives the treatment and grows back with a vengeance.

Guard Anti-M 24 penetrates deep into the biofilms and disrupts metabolism at the cellular level. This effectively starves the micro-organism. The end result is that the growths will die off completely, roots and all. Further, residuals of Guard Anti-M 24 will remain in the substrate and will therefore inhibit germination of spores that blow in for up to 3 years.

If you need something cleaned instantly use Guard Wash instead. Guard Anti-M 24 can still be applied after cleaning with Guard Wash if you desire the residual anti-microbial effect.

Use Guard Anti-M 24 as an Antimicrobial Treatment Prior to Sealing


A diluted solution of 1 part Guard Anti-M 24 to 1 part water can be applied to porous substrates before applying sealers or paints. This will impart antibacterial and antimicrobial properties to the coating applied over it. Just be sure to let the pre-treatment solution dry thoroughly before applying the sealer or paint.

Sealing with a product from the ImperGuard, or ProtectGuard range will keep porous substrates dry and clean. This will prevent organic regrowth for over 5 years.

FAQs


Guard Anti-M 24 kills and prevents the regrowth of mould, mildew, algae and moss on hard surfaces. It provides up to 3 years of anti-microbial protection from a single application. Water-based and safe for use around plants once dry. Protect plants from overspray during application.

Yes. Guard Anti-M 24 can be used on synthetic grass. It will kill existing moss and mould and inhibit regrowth. Apply evenly and allow to dry. Follow label instructions for dilution rates.

Yes, very popular with professional cleaning and sealing contractors. Applied after pressure washing, it eliminates residual biological matter and helps prevent rapid regrowth, extending the life of the clean.
