Hi Guys,

 

This is just an FYI post, hopefully, it will be helpful for others.

 

For years I have been looking for a way to clean my driveway. No cleaner would do it. I was successful

once using hydrochloric acid, but that was not a good solution. Now, finally, I tried this little sandblaster

attachment for my Karcher.  Look at the pictures, freaking amazing !!!

 

The attachment I bought on eBay, for $30 USD, including shipping. They have them for many different brands.

 

Cheers,

luudee

 

 

That looks great. What a helpful device. Thanks for posting. 

I'd been considering one of these myself. Good to see it works well. Next step is to find a good quality sealer to prevent the mold and dirt returning.

OP I may be missing something but how is that any different to using the the "standard" spray attachment for your pressure washer?

It's not mold. It's more of a calcium (I have a well) and dirt deposit. Mould could be cleaned with hydrogen peroxide (that's

what I use in bathrooms). Dirt could also be cleaned with just the pressure cleaner without sand. But these tiles (as well as

sand wash) seem to attract some hard deposits that can not be easily removed.

It adds sand. See the clear tube that goes into the sand bucket?   Think of it as a poor mans sandblaster !  :)

After cleaning last year I started to use 'besbond" so far it appears to be doing a good job, will see after another year or so?

That's a good point. I have been wondering about a sealer. The tiles I have a composite type "Kenzai" brand. But the grout is plain concrete/cement.
