CUTEK® Mould Cleaner

FEATURES OF CUTEK® MOULD CLEANER

It is important for the user to determine the suitability of the CUTEK® Mould Cleaner for its intended application. ALWAYS test product on a small test area prior to applying to any large sections. As the species and condition of timber can vary significantly, testing will enable you to accurately estimate the dilution, time and volume of CUTEK® Mould Cleaner required to complete your project.

Safety and precautions:

Before you begin to Prepare and Protect your timber, note the hazards and precautions and ensure that you have obtained and know how to use the correct safety equipment as detailed in the Safety Data Sheet.

When using CUTEK® Mould Cleaner, all adjacent surfaces and vegetation must be adequately protected. It is also important to be aware of the potential for wind drift into areas with cars or pedestrian traffic when rinsing. Water flush all equipment, vegetation, paths, concrete, asphalt and other adjacent surfaces before and after contact.

Coverage:

Spreading rate is approximately 1 Litre of CUTEK® Mould Cleaner per 5-8m2 of surface area to be cleaned.

Before application, ensure excess dirt and contaminants are removed. Add 300g of CUTEK® Mould Cleaner in 10L of water; thoroughly stir contents until the powder is dissolved. Note: Warm water will dissolve the powder better.

Application:

Using a garden sprayer or soft bristle broom, saturate the timber with the solution.

Using a stiff bristle broom, thoroughly scrub the area in the direction of the grain.

Allow the solution to sit on the timber for at least 15 minutes before removal. Do not let the solution dry on the timber; agitate and apply more solution.

Note: once CUTEK® Mould Cleaner has been dissolved, it must be used within 1 hour after mixing.

Removal:

After 15 minutes, CUTEK® Mould Cleaner can be removed using a high-pressure washer set to approximately 50 bar (750 psi) with a fan jet pattern. Alternatively, a high-pressure nozzle on a garden hose with sufficient water pressure and a scrubbing brush should be effective.

Clean from the highest point and work down methodically using long, even strokes in the direction of the grain. CAUTION must be used when cleaning soft timber. Reduce the pressure or adjust distance from the substrate to avoid damaging the sapwood. It is important to adjust your cleaning process to avoid damage to the wood fibre. DO NOT use “turbojets” on timber.

If the surface mould or stains have not been removed sufficiently, try scrubbing and rinsing again. If the stains have
not been sufficiently removed, reapplication of CUTEK® Mould Cleaner might be required. If there is residual staining, CUTEK® Restore or CUTEK® Quickclean may be the suitable product.

• What problems, if any would occur, if it was used at a lower dilution?

  If CUTEK® Mould Cleaner is not diluted to the appropriate amount, the proper mould killing and sterilising may not occur. Some mould spores are visible to the naked eye. The absence of visible growth doesn’t necessarily indicate that the surface is uncontaminated. Proper cleaning practices need to be adhered to. If stubborn stains have not been removed, reapplication or other CUTEK® Prepare products may be required.

• Will CUTEK® Mould Cleaner effect powder coated aluminium or other metal surfaces?

  CUTEK® Mould Cleaner is unlikely to have impact on powder coated aluminium.

  However, if the powder coating or any other coating has degraded, this will increase the likelihood of unwanted impact. The impact can also depend on solution concentration, temperature, coating condition and dwell time. CUTEK® Mould Cleaner solution may corrode unpainted metals in some circumstances. Ensure any adjacent surfaces where the CUTEK® Mould Cleaner is not intended for are masked so there is no inadvertent contact. Thoroughly rinse off any excess material and adjacent surfaces.

• The instructions say, “Do not to let the solution dry on the timber, agitate and apply more solution”. What happens if you do let it dry on the wood? What should we be aware of?

  If CUTEK® Mould Cleaner is left on the timber, a few things may occur:

  • A build-up of sodium carbonate could form a white residue which may cause staining or effect the coating that is applied on top.
  • It may become more challenging to remove.
  • If that CUTEK® Mould Cleaner has not fully been dissolved prior to application, visible bleaching may be more visible.
• Is CUTEK® Mould Cleaner Biodegradable?

  Yes, CUTEK® Mould Cleaner is Biodegradable.

• Will CUTEK® Mould Cleaner damage my plants and adjacent surfaces?

  CUTEK® Mould Cleaner is unlikely to damage plants and adjacent surfaces. However, we recommend proper care during application and removal be used.

• Can I use CUTEK® Mould Cleaner on other substrates?

  Yes, CUTEK® Mould Cleaner is ideal for removing mould from other substrates like concrete and painted surfaces.

• What do I do if I can still see mould on my timber after washing off the CUTEK® Mould Cleaner?

  Assess your process, including application, scrubbing and removal methods, as well as the state of the timber. Consider an additional application and reapply as necessary.  If staining persists, the use of CUTEK® Restore or another cleaning method may be required.

• Can I use CUTEK® Mould Cleaner instead of CUTEK® Quickclean to clean the wood between maintenance coats of CUTEK® oils?

  CUTEK® Mould Cleaner’s purpose is to kill and remove mould from wood. Where mould removal and cleaning are required, CUTEK® Mould Cleaner is sufficient. However, where general maintenance is required, CUTEK® Quickclean is recommended.

• Is CUTEK® Mould Cleaner a safe product to use?

  CUTEK® Mould Cleaner is a gentle oxygen bleach cleaner, and an environmentally friendly, biodegradable product. As with any chemical, ingestion, inhalation or contact with skin should be avoided. See the Safety Data Sheet and the product label for safety, precautions and handling information.

• Does CUTEK® Mould Cleaner remove the grey from woods surface?

  CUTEK® Restore is designed to remove greying from wood and restore it for a fresh coat of CUTEK® oils. While Mould Cleaner will remove some of the grey from the woods surface, it is not as effective as CUTEK® Restore.

• Do you have to use a pressure washer to remove the CUTEK® Mould Cleaner?

  The best way to rinse off and remove CUTEK® Mould Cleaner is with a pressure washer set to approximately 50 bar (750 psi) with a fan pattern tip.

  Alternatively, a high-pressure nozzle on a garden hose with good pressure and using a scrubbing brush can also be effective. It is important to remove all residual Mould Cleaner from wood before coating with CUTEK® oils.

• Will CUTEK® Mould Cleaner remove stains from wood?

  Yes, it will clean contaminates and remove most superficial stains from the woods surface. For the removal of heavy stubborn stains, use CUTEK® Restore. Remember to always test products on an inconspicuous area prior to full application on your project.

• Does CUTEK® Mould Cleaner kill mould?

  Yes, CUTEK® Mould Cleaner will kill mould and sterilise the woods surface when used correctly. Always read and follow the application, precautions and safety instructions listed on the product label and found on the CUTEK® website.
