LMI glue drying to white?

[ToddStock]

Any of the PVA and AR glues will try white or yellow (TB) if they are used in cooler temps, or have aged to the point where they need to be discarded. LMI White can 'go off' in as little as six months...when it starts drying with a chalky surface or anything other than hard, glossy, and clear, toss it. After having been burned one or twice with LMI White, I test the bottle before use and every month or so after that...scrap is cheap. Currently testing Gorilla Glue White to see if it's a decent substitute...def has a shelf life under two years, as the oldest bottle I have is a 2008, and the glue has separate into an amber liquid and white, chalky paste.

The self life and performance of the LMII Luthier's Glue shows up a lot on the Internet. I did a little investigating, since LMII does not have "as far as I know" a chemistry lab, it simply makes sense that they sell a re-packaged product. Here is the last disclaimer on the LMII MSDS sheet for the glue:Disclaimer: This information is provided in good faith and is correct to the best of Forbo's knowledge as of the date hereof and is designed to assist our customers; however, Forbo makes no representation as to its completeness or accuracy.

So again "speculation on my part" it seems to me the six month shelf life factor starts when the five gallon buckets that LMII gets, are filled -- not necessarily when they get around to re-packaging. BTW not sure which LMII advertisment but one can see the pails of glue in the picture.For about 40 years now I have been pleased with "Titebond" original no creep no bridge blow off problems. -- more than $.02 but interesting none the less.Ken CierpKenneth Michael Guitars est. 1978

I prefer the LMI White, but only use it for binding, where the clear glue line is helpful on maple and some other binding woods. Titebond and LMI both creep at elevated temps...I tell folks not to cook their guitars, but use hide because some folks do

Grizzly also has a similar glue. I think you may be on the money here Ken. I had a bad bottle and It left a bad taste in my mouth , but the LMI glue scored well in the glue test posted in Guitarmaker in the last issue. Its numbers well exceed HHG. I may have to try them again.

Hi gang,

I worked at a major glue company for 31 years. We made glue for many of the major suppliers. We sold in tanker loads to the companies that repackaged for the consumer.

I will attest to the fact that glue is hard to preserve. It is prone to microbial attack. It is best to work with glue that is new, unless you have tested it recently. Comparing the price of a guitar to that of a tube of glue, the economics dictate new product.

Each month I seem to convert more joints to HHG or Fish Glue. As a result, the bottles of TB and LMI White seem to be collecting more dust on the shelf lately.
