A friend of my wife called and asked how to thin latex paint. She was using one of those hobby paints and the container may hold a TBS. I told her to add a few drops of water, stir and continue until thin. She said that wouldn't work, she tried it and it was too dry to thin. Then my wife told her to thin it with Hydrogen Peroxide drop at a time and stir. Worked like a charm. The chemical symbol for water is H2O and for peroxide is H2O2. I guess the extra 2 Oxygen molecules made a big difference.

I've forgotten what it is called,but HD sells a product for thinning latex paint. While I have used water to thin latex, it isn't recommended. H2O2 is the formula for heavy water. I never knew that meant hydrogen peroxide.

I have never heard of this, I have always just used water also.  Thanks for the lesson this morning.

Interesting. Thanks.

For thinning water-borne stains or making my own glazes, I use propylene glycol.

For those wondering this is NOT the same thing as antifreeze used in most automobiles which is ethyl glycol.  It is used as an antifreeze in applications where it is possible to be ingested by mistake.  Such as in cooling / heating systems in a home.

The chemical formula of heavy water is H2O. It is often written as D2O to indicate that the Hydrogen atoms are Deuterium. Deuterium is an isotope of Hydrogen, as is Tritium---------per the big G(google)

wow----digging up OLD posts. Don't even remember that one above. And I'd question the heavy water H2O statement.
