Read somewhere that Ammonia should be added to the Methyl Cel
solution. Is that necessary? Has anyone tried it? How much methyl cel
do you use per gallon of water?

- I use methyl cel that I buy from Pro Chemical. I use 1/4 cup per
gallon of water (my well water - it is on the hard/alkaline side).
1)I put 3 gallons of well water in a bucket.
2)I add 3/4 cup of Pro Chemial's methyl cel & stir it up with a
giant whisk so it is in suspension.
3) I add 3 to 4 teaspoons of household ammonia & stir like crazy.
The ammonia makes the water more alkaline which sets off a reaction
with the methyl cel & makes it thicken up. I keep stirring for maybe
5 minutes until the methyl cel loses its cloudiness & is thickened.
4) I let it cure for overnight if possible.
5) Pro Chemical's instructions say to add a teaspoon of vinegar for
each gallon of water after the solution has rested for 30 minutes, &
I used to do this but I don't anymore. Maybe I should, beats me. My
methyl cel lasts well for a week or so if it doesn't get hot. I keep
my buckets of made up methyl cel sealed with screw lids & it lasts
for a long time until I'm ready to use it.

- I got my methyl cel from a paint shop (it's the one used for wall
paper), but have not been able to find any ammonia yet. That's why I
was wondering if it was absolutely necessary.

might not give you very good results. Regards, Gail

- The methyl cel Pro Chemical sells works well (at least for
acrylics). Just follow their directions for mixing (including the
ammonia part). They have a web site. If you want to order in larger
quantities, just call them.
