Thanks guys

Could someone give me a brief explanation of what is it? Do you get it in powder, liquid? How is it mixed, etc? Thanks

We broke about 4 tiles during the work. We did a lot of roof walking. :D :D :D That’s me…discovering some stairs under the sand! Thank you Beth. The owner was tired of rough finish walls and rounded edges and corners. He wanted smooth and square finish. A new coat of cement had to be applied. I think he didn’t knew what use to give to the money. This house it’s in a very healthy neighbourhood, called “Quinta do Lago”( check the net). and there are a couple of unbelievable stories; a guy bought 2 adjacent houses there, had one house demolish and built a garden on is place; another guy, did even worse, he bought a house with a swimming pool but he wanted the house where the pool was and vice-versa. He had everything demolish and had it built the way he wanted. Sounds unreal but it happened!! This is definitely the market I want to enter!

Here's my pal finishing the final bit.

and a few more:lgbonk:

Here’s a job I did throughout November and December. I was called to bid on this job for sand blasting the paint out of the wall to bare cement. I said “Ye sure, no problem at all”…how naïve. 27 Days, 40 tons of sand (you eared me) and plenty of spare parts later, we had the mansion you see in the pics down to bare cement. It took 2 machines; my machine, 3000psi @ 4gpm, and a rented, electric one with the same characteristics, and 4 men; 2 blasting and 2 cleaning the huge mess, working 9 hours a day/6 days a week. Didn’t got great money in the end, but then again, this was a “baptism of fire”. I learn important lessons with this job that I would like to share: -Never overlook the details: these are the ones that can “kill you”. -Never think you know it all: every situation is different -Can’t take an advice for granted; I asked for an advice on how much I should ask to a fellow painter and his advice was 5 times less money then what I got (still little). -Always make a test… in several places. It was a big disillusion when I start blasting and only a little bit of paint, from the size of a coin, would come out. I got easier walls, difficult and extremely hard. There were other things, but I believe these are the ones witch made more difference.

Get "Power washer's Guidebook". I think is a great book. You can get it here: http://www.adpub.com/ctimes/

That can be arranged...in exchange for some knowledge.lol :deal:

Been researching in the meanwhile and read some mean, scary things about that stuff. Things like: if you touch it, you’re dead; if you breathe it, you’re dead …not sure if I want to get it any more.Yes, Quarteira is in the province of Algarve (check pic), in Portugal.

Jason, I’ve been trying to find that HF but as been difficult as I don’t know the translation to my language. Do you know the chemical formulation?

My …where did you learn all that? Thank you so much Jason.:D

Thanks Jason, Hot water is not an option at the location, so I guess I’ll have to do my best with cold water and the products you’ve advised. Why do you advice alkaline (I want to look god if customer ask!:) )? What could be a good surfctant?

Here's more.

End up using cloridric acid, worked fine but I had to rinse like crazy. I had to anyway; there was a lot of grass there.

Muriatic?What ratio? So, I'll be allright with cold?
