Paint.. Exterior

Re: Paint.. Exterior
bill belive me I have used every type of sand I can get,
some better than others but ( the builders merchants tell me it is washed !!!)
but a third party controlls that so I can only take their word for that
I had a nightmare job once
I had to build a retaining wall
THINGS I DONE TO PREVENT DAMP-
plastic membrain behind wall , damp proofer in the cement render, plastic paint finnish, drainage holes in block work
After about 4 months the paint started comming off and render behind degrading
So I went back cleaned off the flaking paint repaired the render with water proof pool adhesive re painted with quality plastic paint
After about 4 months it was the same as befor
so I went back, cut a chase in the render at just above floor level and filled with silicone in an attempt to stop the render sucking up damp
made good and re painted with plastic paint
GUESS WHAT it came off again !!
So I went back hacked the whole lot off, back to block work rendered with white sand and, white cement ( white sand is by probuct of marble cutting and contains little salt )
then finnished with white sand and fine gravel peble dash un painted
NO more problems THANK GOD !!!

Tony, I'm not a builder, and I can't tell you what will or will not stop damp. All I'm saying is that breatheable paint is no cure for salt spalling.

HI bil
Yes damp, big problem here !!
Got A reply back from a solar factory they think a solar desalinisation unit would work but they dont think it would sell well because the countrys that need it ie Africa are poor and cant afford to buy them.
I think I may be able to modify a std unit to de salinate water

Flow sea water slowly over the top in a film to cool the top, and collect the water as it drips off. Simples!

Re: Paint.. Exterior
thanks bil
I have seen that design, should work well but not to sure if the out put would be great enough
I have a friend he has a well producing salt water he needs about 1 cubic meter per day
one factory came back with a quote of 70000 usd for plant 100m area was required for the collectors
BIT EXPENSIVE !!
