Re: "Spring Cleaning"

Have to spray some insecticide sa buong bodega and bilad yung mga kahoy na nakatago. Mga gurus may suggest po ba kayong wood teatments na pwede ko gamitin? Gamit ko kasi dati malathion

Re: "Spring Cleaning"

Malathion is a no-no...very bad to your health...or at least to your "old carpenter's"

although very powerful to kill insects...mlalathion and similar insecticides may stay inside wood and becomes VOC's (volatile organic compounds) and when the wood impregnated with it becomes a nice piece of furniture, it may slowly emit/release this bad chemical..you and your children including pets may absorb/inhale eventually slowly.

so far i have no substitute for Solignum...does anyone know of any human friendly wood treatments to date? coz id gladly shift...solignum is neither envronmentally or human friendly.

Re: "Spring Cleaning"

Sometime back, Willy Fernando asked me to treat my wood which he dried in his kiln with Lentrek. He says it's better than Solignum. Can't recall why but it has something to do with the crystallizing components.

Could not find Lentrek but got Hometrek instead which, the hardware store says is the new name. Can't verify if so but used it.

Re: "Spring Cleaning"

Well I use Malathion or Folidol for my plants to kill aphids, ants and other pests that infestate my okras, eggplants, tomatos, pechays, sweet corns etc at their growing stages and has become very effective but for wood preservation, yes against termites and wood boring insects, Solignum clear and hmmmmmmm Lentrek, are you sure bro ding of Lentrek, I think this is the one we use to pour or spray on the soil to kill termites before house construction begins, but correct me if I'm wrong. :p

Its been years since I've used the Lentrek brand, can't remember whether its for wood or soil treatment. :dunno: :confused:

Re: "Spring Cleaning"

You are right, Rosy. Lentrek is primarily for soil treatment. Also checked the Jardine website and Hometrek is, indeed, the new version.

But Willy told me they have actually done tests and preferred Lentrek to Solignum.

Hope Willy can chime in.

Been using ethylene glycol (EG) with and without borates (boric acid/borax). No long term results yet to report, but others have written extensively on this. See pics and the two links in the below thread. I did notice that it appeared to cure a bukbok infestation in a test piece of bamboo and prevent re-infestation.

EG -- insecticide, fungicide, wood stabilizer (claimed)
Boric acid in water -- insecticide (stomach poison), fungicide
Boric acid in powder form -- insecticide (stomach poison, ingested when insect cleans their legs? / cuts exoskeleton like broken glass?)
Diatomaceous earth, food grade -- insecticide (cuts exoskeleton like broken glass)

Indoor only, otherwise probably needs regular reapplication

Thread: Wood Stabilizers

Re: "Spring Cleaning"

Ahhh, yes. Good ol' engine coolant. Also read that it stabilizes wood well, even on boats.

My only hesitation in trying it is that it affects finishing-ability and glue-ability of the wood. I will probably experiment with this one day.

Re: "Spring Cleaning"

I think this is the article that was cited on issue of epoxy bonding to EG/borate-treated wood. Very limited study that offers the interesting possibility that epoxy bond can actually be stronger depending on wood type and treatment mix.

The Effect of Ethylene Glycol and Sodium Borate Solutions on the Adhesion of Epoxy to White Oak and White Pine Samples

So far have applied the EG+borates recipe in Dave Carnell's famous article to tanguile baseboards, etc., as alternative to Solignum. His recipe calls for a lot of borates ... amazing how much powder can be dissolved by heating the coolant (to beyond the boiling point of water, see pics in thread). After the thing dries on wood, some powder can be seen on surface. Just needs to be brushed or wiped away prior to finishing. After the usual finishing steps, I didn't notice any difference in appearance of the treated wood.

At such high concentration, the borates tend to crystallize out of solution after a few weeks, requiring reheating to re-dissolve.

In future, will probably lighten up or maybe just do away with the borates, since IIRC, Carnell article says that EG by itself is most effective. So why bother with the borates?

Anyone know where to get concentrated engine coolant cheaper than the P189.75/L for that 'Springfields' brand at Ace?

Re: "Spring Cleaning"

thanks for the info about the lentrek now hometrek..i used lentrek maybe 15 years ago...
soil experts in this tropical country suggest retreatment of the 1meter perimeter soil with termiticides every 6 months since during the rainy season, most if not all of these chemicals get diluted or washed away.

from what i know ethylene glycol is antifreeze (versus engine coolant, confused..) and in the states, some poor alcoholic folks use that as an alternative to alcohol..i.e. moonshine which they say tasted like between vodka and whiskey...

meantime, i still have plenty of solignum to use as wood preservative...and i have proven that it can treat bukbok infestation...but when the infestation is so severe, the wood is better suited perhaps as firewood coz you will be so frustrated during the finishing stage leveling up those worm-like holes made by nasty bukbok.

Never thought of it that way. Have to stop using malathion. Thanks very much sir V

Re: "Spring Cleaning"

Rosy, Balarila, Guad,

Thanks for the info didnt know that engine coolant is a great wood preservative gotta try it

@V
The wood is for firewood na lang mukang hanggang loob yung infestation. Buti na lang hindi nadamay yung iba 🙂

Yes. I'm one of them who interchange those terms erroneously.

Wonder how they used EG for moonshine! Thought the stuff was toxic.

Re: "Spring Cleaning"

@balarila,

hehe...i also erroneously wrote that ethylene glycol as a substitute for alcohol...

truth is...ethylene glycol can become a contaminant in illicit distilling process using car radiators as condensers to produce moonshine.

but its enough that we know that e glycol is a poison...its a bonus to know that we can use it as a wood preservative.

cheers

@Ding,

Forgive me for creating a confusion. The actual product I have recommended is CISLIN 25, a Residual insecticide that we have been using as oppose to the popular brand (S) you guys have mentioned. I had a chance to work on a large project w/ DMCI way back in the late 90's and recently in 2009 w/ the Ayala Alveo group on Crane mats cut from Yakal, Guijo and other hardwood that are prone to insect infestation. These are freshly felled trees and cut as flitches or square logs but carelessly stored. We had to contact a friend consultant from the PHILIPPINE PESTICIDE AUTHORITY and tested several treatment brands available at that time to resolve both storage and post processing treatment issues including finishing. We were surprised at the results we got most especially from brand (S). Apparently the product had been diluted considering its sealed packaging and what was more shocking was that the tests revealed a disturbing result. The formula in it's current form produced crystallines that actually became food for the insect because of the high sugar content present in the base ingredient (Camote or sweet potato). From our conversations I mentioned that CISLIN is hard to come by nowadays and that some friends have used the brand LENTREK as their alternative. I am for any brand that may perform as good as CISLIN but for the moment we no longer use that much insecticide for our products because as you know my IROKO is naturally resistant to PESTS. A lot of manufacturers have recently shifted to GREEN formulas so i haven't tested the differences in the current and usual brew. Here are a few things i consider in my insecticide selection:

It must have that residual effect on treatment.
It must be safe for Humans, animals and plants.
It's dilution base maybe water, Kerosene or any mineral based spirits.
It must have no effect on finishes like staining as result of it's residual characteristic.
Most of all, it MUST DO what it was really designed for. KILL PESTS NOT PETS. Oh, include Plants and Humans as well.:rolleyes::D

For those who wish to see the data sheet of CISLIN 25 for your guidance heres a link you may use... www.bayeres.com.au/resources/uploads/label/file9137.pdf
I just don't know who carries CISLIN's local distribution nowadays.:whistle:
