Can I use 12"x12" concrete pavers to redirect water away from my foundation?
The soil surrounding my 76-year-old house in Los Angeles is often wet or moist during our winter rainy season. Over the years, the excess moisture intrusion from rain and the ground movement that followed the rains, damaged some parts of the foundation where the most water got through to the foundation. The worst portion is a 12-foot section of foundation that is adjacent to the outside of the fireplace. It is this 12-foot section that I would like to improve.
In addition to putting up gutters, I'd like to do something simple & cheap to redirect some of the water away from the house. I thought of using simple, cheap 12"x12" concrete pavers, perhaps 2-deep, to create a sloped 2' by 12' hardscape to make the rainwater roll away. Is this a reasonable idea? Is there something better than pavers I might use? Should the pavers be placed in a layer of sand or is there something better to use as a base material that might hold less moisture?

Need some advice on copper sulfate for copper stripping
Hey everyone, I’m looking into using DC current to strip a copper coating from an MS (mild steel) base.
I have a few questions about using copper sulfate (CuSOâ‚„) for this:
* What concentration of copper sulfate would be a good starting point?
* Do I need to add sulfuric acid? If so, why?
* How do current density and temperature affect the stripping process?
* How can I avoid damaging the steel once the copper is removed?
* Is there anything I should test before deciding on the electrolyte composition?
If anyone has experience with this kind of process, I’d really appreciate your advice. Thanks!

Why won't my hardboard dry from a few splatters of water?
I just bought some hardboard from the hardware store, had it custom cut for a project, and it was raining when I bought it. On the way to the car, it got a bunch of individual water droplets on it. It didn't get soaked, just slightly rain-splattered. I've had them home now for 5 days, the two with splattered sides standing upright with the splattered sides exposed in order to let them dry. They will not dry.
Even after almost a week, they still have these dark spots on them where the raindrops landed.
Is there any way to force this to dry? Is it perhaps already dry but now discolored in some way from having been wetted in those spots? If I use this for my project, is this likely to lead to mold or anything in the future?
