How to soft wash slippery & rotting decking

 

Slippery decking can be dangerous as well as unsightly. It can become covered with biological growths, especially algae, on which people can slip and break bones.

And of course it is simply unpleasant to sit out on a filthy, mouldy, rotting decking that was erected to be a joy.

 

Softwashing wood decking and other wooden buildings and fences is a huge market for softwashing contractors

 

A light power wash to remove the worst of the algae, followed by a treatment of Benz Bio Cleanze will give neglected decking a new lease of life.

If you can't get hold of a power washer, a simple watering can and stiff brush to clean off the algae will work wonders.

  • No more slippery decking
  • No more unsightly staining

Although a light power wash or scrub will improve the appearance of decking it's essential to follow up asap with a treatment of Benz Bio Cleanze. The biocide acts in a similar way to sterilising a babies bottle, ensuring the spores of the biological growths are killed.

This means the decking will remain clean for a considerable time, especially as Bio Cleanze offers long-term residual protection against re-colonisation by algae spores.

A routine application every 6-18 months of Bio Cleanze on bare timber decking will keep it looking great. Although all timber is different it will probably fade to a natural grey-silver colour.

Can decking be stained, oiled or varnished after treating with Bio Cleanze?

Wood decking, and other external wooden structures, will be ok to stain, oil or varnish once completely dried out.

Bio Cleanze can be used to maintain decking after staining or oiling but will only be able to treat the relatively surface colonisation. This is because the oil staining will hinder the product from penetrating so deeply into the wood. Water-based stains probably will not inhibit the penetration of Bio Cleanze, although we have no data on this.

Varnishing, and similar non-breathable sealers, will prevent Bio Cleanze from penetrating below the surface. It will still treat any surface colonisation but the long-term residual protection from re-colonisation will be lost

In many instances the best way to maintain timber decking, wooden buildings and wooden fences is to never treat them with oil, varnish, or paint. Simply using Bio Cleanze is often more effective and we believe most of your customers will enjoy the results far more.


Benz Bio Cleanze helps protect wood from wet and dry rot

The active ingredient in Bio Cleanze is used in commercial wood preservative products and processes. And in our experience, following up the first treatment with 6-24 month applications (time scale depends on the local environment) will significantly help prevent wet and dry rot.

Other timber structures such as timber sheds and wood fencing can be similarly treated to improve their appearance and help extend their life.

Children & animal safety: If wood decking or other wooden structures are to be used by children or animals apply Biocidal Wash at a maximum dilution of 50:1. Ensure surfaces have completely dried out before allowing children and animals access to them.


General principles for soft washing wood/timber

We recommend using Bio Cleanze for softwashing wood whenever possible. And of course, even when confronted with extremely bad colonisation customers will expect it to be cleaned reasonably quickly.

For such surfaces, and customer expectations, we suggest using Benz Lightning Cleanze first, at the lowest viable dilution, for the shortest viable contact time.

It is important to pre-soak the wood to keep the chemical on the surface, which will enable it to clear the worst of the colonisation without harming the wood.

What we do NOT endorse when using Lightning Cleanze to soft wash wood:

  • Using at an unnecessarily high-strength.
  • Not pre-soaking the wood the wood before treating.
  • Leaving on the surface for unnecessarily long periods of time.
  • Using power washers at high pressure to rinse.

Used responsibly and with care Lightning Cleanze – with light pressure washing – can be a helpful adjunctive product to rapidly remove heavy colonisation from wood surfaces that is the result of years of neglect.

Complete the job with a treatment of Bio Cleanze and continue ongoing maintenance with Bio Cleanze only.

 

COMPOSITE (PLASTIC) DECKING

Use Benz Lightning Cleanze for the first clean (5-10:1 depending on the severity of the contamination).

Then spray with Benz Bio Cleanze at 50:1 for quick and profitable ongoing maintenance (6-18 months depending on the local environment).
