how do I make ..white wash?

Answer 1

Whitewash...hmmm.
Whitewash, or calcimine, kalsomine, or calsomine is a type of inexpensive paint made from slaked lime (calcium hydroxide) and chalk (whiting). Other additives have historically included water glass, glue, Portland cement, salt, soap, milk or flour.
Mix in a large bucket, a five gallon paint bucket is ideal:

3 large coffee cans of hydrated lime (about 12 cups)
1 pound or 1 small coffee can of salt (about 4 cups)
2 gallons of water
When you mix this together, mix a little lime/salt, then a little water, then a little lime, etc. It you just dump it all together it's like stirring boat anchor. You should let the mixture sit over night, but we usually just use it right away and have had no problems.
The white wash should be fairly watery, remember it's a wash, not a paint. Give it a stir once and a while as you use it.

To use the white wash, just get a big brush and slop it on. Don't worry about getting it on your clothes, it washes out very easily. It may seem like it's not covering very well as you paint it on, especially on new pine 2x4s, but it will whiten up considerably when it's completely dry, be patient.

In no time at all, you'll have a brighter and fresher....whatever you're whitewashing!

Note:

I have been told you can improve this white wash recipe by adding about a tablespoon of powdered alum per gallon of whitewash. This supposedly will improve it's "sticking" characteristics, i.e., makes it more resistant to rubbing off. I have not tried this and do not know if it helps or not.

I was also told by the same source that, to really make it last -- get some hide glue flakes. Dissolve about 1/2 a pound of glue flakes in enough boiling water to dissolve thoroughly and add it the recipe (with alum added). This supposedly reduces the frequency of re-whitewashing at minimal additional expense. I have not tried this and do not know if it helps or not.

If you mean whiter whites....bleach!

Answer 2

White wash what???? Do you want to make a white wash to paint your fence? Or do you want to wash white clothes in the washing machine? Add bleach.
