Hi Joe and thanks for your question,

I am unsure what Kingspan “pdf” cladding is. Could you give more details?

Certainly with regular Kingspan steel cladding Blackwash at 10:1 should easily take care of the problem. In the video you see Ben using Blackwash at 10:1 on steel cladding and there’s no need to follow up with Biocidal Wash.

On render we recommend post-treating with Biocidal Wash no later than 12 months following initial cleaning with Blackwash. This will ensure the spores are killed deep into the render and will leave a residual protection that will ensure your customer can enjoy clean render for 2-3 years on average (depending on prevailing weather and location – can be longer). You can post-treat on the day of cleaning with Blackwash if your customer wants the best possible clean and protect service and is willing to pay the extra.

I hope this helps.

best wishes,

The good news is that there are ZERO customs duties to pay on Benz products.

Brexit has brought about many changes and challenges to business supply chains. And there's a lot of fear floating about regarding the excess taxes being levied on customers when ordering from EU-based companies.

So we want to reassure all our customers that we are able to continue supplying both our Irish and UK customers - with no additional duty, customs costs, or delays.
