said in video that spraying cools it down and too much borax comes out of solution

What if you put a coat of sealant over the borax treatment?

Just spray it on brother

Thanks!

In our case the cost came out about the same as using cement and rebar support beams. And the process was significantly faster which resulted in savings in labor costs. In my opinion, the steel beams are the obvious solution if you want to avoid support beams in a large open space.

@@buildinginmexico Great, thank you very much for your prompt response. We are planning to build our house in Mexico City, and your reply will certainly assist us in this process. We've heard about prefabricated framed steel beams, and other potential solutions, but nothing seems as straightforward and dependable as this fast and reliable construction method

I'll let you know once we finish.. The price of materials has been going up steadily since we began.

You could use a pump sprayer with a metal tank instead of plastic, and duct tape a hot plate to the bottom to keep the borax in suspension.

I believe you are correct. It would appear They've waisted their time .

Borax dissolves into: 2 Na, 1 tetraborate, it's a salt and it dissolves

@kiyannareynard-eu7ph is correct. The chemical reaction is: \( \text{Na}_2\text{B}_4\text{O}_7 \cdot 10\text{H}_2\text{O} ightarrow 2\text{Na}^+ + \text{B}_4\text{O}_5(\text{OH})_4^{2-} + 8\text{H}_2\text{O} \). Warm water facilitates this process.

@@kiyannareynard-eu7ph Borax does dissolve in water to form sodium and tetraborate ions

@@kiyannareynard-eu7ph borate treatments leave a white residue and crystals on the surface of the wood. If the water carries the salts into the wood it would be good. The water or any type of glycol eventually get absorbed or evaporate leaving the salts behind. Drips show up as white residue. If left uncoated in a moist environment, like outside, they'll just wash off. The wood needs to be coated to retain the salts. Glycols dry much slower. They're used to allow the salts/solution to penetrate more deeply, theoretically having more time for the mixture to soak in. Borax is a cleaning agent. Borate is an acid used as a pesticide. They both contain Boron but one is basic and one in an acid.

Foliar *leaf based* application is best for agricultural applications as boron CAN be toxic to root systems. Boric ACID is best as it reacts with the Potassium in plant biology rather than making the reaction more complex with the sodium ions in regular Borax. Boric acid is antibacterial antiparasitic and antifungal. Helps with all kinds of rot/funk.

Have you applied gypsum to the apple trees? My grandmother used to grow apples out here in hte desert southeast.. when no 0one else could..

there are several common glycols and you want propylene glycol not ethylene. that's a solvent and carrier, alternative to boiling water

good luck getting them to mix

@@Nilhilustfrederi but propalin glycol wont kill bugs like ethylene glycol will. works great on fungus and silverfish.

also, what is the gauge of the corrugated steel decking. Thanks in advance !

I don't remember. I'll check on that. There are charts online that show you the span and weight bearing characteristics of the different thicknesses of the decking. You'll want to look that up to figure out how that information fits in with your specific requirements and select the thickness best for your application.

The roof will be wood beams with wood planking covered with torch-down rolled roofing and clay tiles.

We left four pieces of rebar protruding up from the support column where beams will rest. The plates have holes cut to fit over that rebar. Once the plate is in place it is welded to the rebar and the rebar is cut off flush with the plate. The beam is then placed on top and welded to the plate.
