Great advice Roger

Thanks Roger,

I'll invest in something to cover plants, lawn etc. I do have a sky vac which can suck any water up so perhaps that's something.

Basically though if it does go on anything, rinse the heck out of it? I'm fine with that.

My website, if I'm allowed to put it here and please delete if I'm not is holliesservices.co.uk, well out of your area though and from what I've seen of you, I'm no threat to you in any way. We're a very young company.

Thanks again for your help.

No, just good to see other peoples sites, nice work on the tarmac impressed.

It was quite a job, I was alone and it took 2 days. I was bloody knackered and filthy afterwards too!

I've quite a few more to add, it's moments like these I should be adding them.

I'll get off here now and try and get some more before and afters on.

Thanks again.

My apologies for more questions in advance.

I did a test on a single piece, of what it turns out is Italian Sandstone which I believe is highly porous and not Indian Sandstone. I did a 2 - 1 mix of water and Sodium Hypochlorite. It did the trick beautifully. Albeit bloody dangerous stuff which I learned a few lessons from.

I'm thinking on this job as she breeds dogs and has 28 of them, yes, that's no typo, I need to be a bit careful.

Can I assume, once seriously rinsed and DRY, it's safe for pets?

Like weed killer, once dry, is it safe?

The customer has agreed to keep the hounds inside all day but I'd just like to to know of potential issues others have had with this.

I'm also thinking, do you treat with this first and then pressure wash off or clean first then treat what's left then re pressure wash after?

My idea, as the pointing's buggered and he has a chap to re do the pointing is to deep clean with no chemicals, treat the terrible lichen affliction with sodium hypochlorite after, re pressure clean to throughly rinse off, then his chap comes along and repoint's it?

Please tell me if this is a good course of action or what LLL or RA Roger would do under similar circumstances.

I'd be most grateful,

Thank you.

Ps. His wife has let me know she'll put my head in a bucket of the hypo mix if one of her dogs goes ill. Sorry I'm just a bit concerned. She's one dangerous kick boxing champ of a lady too.

I use hypo when people have dogs and have dogs myself and clean my Indian Sandstone the same way, but if you are really worried then the other course of action is to use heat so you would need to rent in a hot machine, and you really wouldn't need to use chemicals or at least not to much.
If you g the hypo route yes you really need to flush/rinse everything off no matter how long it takes.
As for weed killing, we don't offer this service as if you are doing it commercially you need a PA1 & PA6 license.

[Branston]

No I think I need to go the Hypo route, rinsing a lot is fine by me.

Again though, once rinsed and dry is it fairly safe to let the dogs back out? I know with a lot of weed killers they say once dry they're ok and just wondered if it was the same principle.

I don't for the record use weed killer, which is ironic considering the properties in sodium hypochlorite.

Many thanks Roger.
