Black mold on walls

I finally decided to deal with what I'm convinced is at least partly mold.   My idea is that the dust from the top of the wall washes down in the rain and sticks to porous paint.   The constant summer time moisture then turns it to mold.

All flat paint may not be as porous as the next but I've used a number of brands and qualities of paint and most of them watered to some degree or another.  The inside of this one meter wall on the roof is stained the same way all around which makes me think I used the same paint. None of the house outside walls have this stain .... so maybe paint quality.

My treatment, which I think it needed, was to scrub twice with a brush, spray pure cloro the next day and then paint it with undiluted exterior semi-gloss.   The new paint is actually shiny so I assume less will stick to it or absorb into it.  The catch is I'm finding out what a real good paint job costs because this paint is expensive. Still much of the house that never gets wet so I don't have to paint it all at once.

Under ground water leak

I've been watching this water leak for a few months. I thought a leak and others thought just from a drip from the filters above.  It finally had a little stream of water even if ever so slightly.   The ground here swallows water very fast so very easy to miss a small leak.  I vaguely remember the ridged black pipe we were using was just a little short and not flexible for a turn like this.   It lasted a couple years but eventually decided to disconnect. May have been effected (was effected) by settling under the water spout.  

A two day project and more digging than I want.   Had to decide on the flexible hose to make that connection because the rigid black pipe is not flexible and basically brain dead.  20 pesos a meter for the clear stuff, very flexible and as strong as the black stuff. Actually both are easier to work with if they sit in the sun a few hours. The weak part are the hose clamps that corrode and become useless. A soldered copper pipe from one end to the other is a better solution.

All about water prep this time

Three water related projects that are mostly done. Only the complete impermeabilizante job of the roof is left. Much of the roof was just a cement wash over tile and then coated with impermeabilizante. Sometimes the wash lifts and sometimes foot traffic wears the coating down. Unfinished tile or cement is porous so you have to paint or seal it somehow. I've done the patching in obvious places, next to paint the whole thing.

While crawling around the gas tank (background 2nd foto) I noticed the seams rusting.  Then I noticed any little scratch had rusted.   Then I noticed on both rounded ends the paint had little bubbles with no apparent damage to cause them.  A few bubbles had broken and rusted in side.  This tank is only 3 years old.   I know it sits in sun and rain uncovered but still ....  can't they coat something as possibly dangerous as a gas tank a little better.   So there it is, sanded and painted and I'm thinking about a cover.

The final foto is of the not quite aesthetically pleasing solution to keep roof water out of my yard and into the street.   I really preferred the ceramic scuppers on that side of the house but the first one was removed because water was draining right over the front door.   This one was removed because I don't need lots of water in my yard in a heavy rain.  It all ends up in the street anyway so why not direct.   The plastic pipe off the roof is kinda funky Mexicanada but it'll do for a few years.

Earth bag construction on the Costalegre

The builder and others also call it Adobe Bag and Superadobe construction but I'm not sure you couldn't use any clean dirt, either moist or dry. Nobody went into any detail on what constitutes Adobe ... as in; mud, clay, straw, fiber, etc. Lot's of sites and pages on this kind of construction "out there" so we'll find the best answers when the actual time comes. Personally I'd love to buy an adjoining lot to mine and experiment with things like this and a real vegetable garden.

The casita builder below has a screen name of Mazinka and lives in or near La Manzanilla north of us in Melaque.  He just suggested that the fill earth should have a certain amount of clay and sent this link - What is Super Adobe .  The video on the bottom just has some ideas for something similar but I much prefer the palapa roof and other local ideas.   Stucco or mortar directly to plastic does not sound secure and I would definitely try to attach chicken wire like they do on old Adobe restorations.

3 new Neem trees on Pinal Villa Plaza

These are two of the 3 new Neem trees I've been planting on the plaza.  My Neem had about 10 babies this spring and I put them all in buckets.   3 neighbors have them in their yards and I still have three more ready to plant.   Someone even cut the grass yesterday and with all the rain we've been having it looking real nice.

The store owner on the corner wants to cut down the only tree there because it split in a wind storm but it's the only shade around.   Hopefully in 6 months these will be shade trees.   Mine that is about 2 years old is over 20 feet.
