Been asked by a customer if this can be cleaned off.

Composite stone so dont think 3600 psi a good idea ?

Is there a product out there that can shift this staining ?

Thanks in advance.

Hi Richy,

Are you getting your hypo from somewhere in Cardiff? Let me know as I'm on the lookout for some this week.

Cheers,

Huw

no, I cant find anyone in cardiff. I rang around a few companies, but no luck, not at the right price.

Any swimming pool companies local to you guys? They will stock it or have a supplier that stocks it.

Hi Richy,

I've found these on Penarth Road

We've got a lot of K-rend to clean over the next couple of weeks and wanted to try some of this hypo. Any tips please? The apartment block walls are currently covered in algae/black deposits.

Not had much success with K-rend with previous chemicals in the past.

Cheers,

Huw
