Concrete Pillars

Very wise indeed Neil :Image9:

Hmm might pass it on then I've been really put off now lol I understand what you all say though, thanks for the advice peeps
 
Well I have power washed concrete pillars before on a low pressure with out a turbo nozzle. Any I have done have came up fine. I find that they have been left for years without any care and are green, power washing brings them up fine. Of course if it's a perfectly kept house with very fussy owners who want to know exactly how you are going to clean it and are prepared to pay a lot for a 'chemical clean' then that's fine but if it's a normal person who just wants the green taken of then in my experience a light pressure wash is fine

 
Aarrgghh its well annoying I've been we'll put off now but i don't want to tell the customer I can't do it /emoticons/sad.png

 
This may be of interest Neil if you have the funds to get trained properly and buy the kit you would need http://www.stonehealth.com/

I personaly sub the work out myself to a local masonary cleaning specialist as using a pressure washer can easaly damage the stone substrate, mortor joints and detailing like edges/mouldings.

Last thing anybody needs is to damage someones home because they take a chance and are not trained in using the proper kit and cleaning methods.

Go ahead and do the job buddy, I'm not saying I would achieve a better finish than yourself, I'm just advising potential problems in my experience what can happen, this is some of my recent work on stone.
WOW !

the work you have done there looks the nuts mate, did you just use a jet wash or chemicals as well?

He's mentioned chemicals before. Doubt it's just a p washer lol

 
The headstones I do are all done by hand/chemicals.

The steps in the picture are pre treated with a chemical wash and then pressure washed.

 
Good stuff. Not that I'm gonna use em. But what sort of chemicals.

Acid wash type chemicals?

 
Any hard surface area, so patios, paths, walls, drives etc are washed down on low/med pressure to remove most crud and then treated with a chemical wash. A mix of altex ( local supplier of a algae killer ) or moss go but that's very expensive, and then liquid cholrine 14/15% strength.

It's all about dilution rates really, too strong and you stain or damage things and too weak you are left with things like black lichen spots.

There is a new window cleaning round near me just started advertising on Facebook, he has a before and after picture of a patio he has done, after he has washed it with his water pistol....sorry karcher, it looks shocking. There are black lichen spots far more visible after cleaning, I hate the fact people may pay for this and think that is how clean all professional cleaning companies would have brought it up. And he charges double my square meter rate!

Rant over....it is Sunday!

Cheers Kfh.

 
Cheers mate, not gonna try it tho.

Do little p washing and I don't even do it tbh /emoticons/smile.png
