Making Your Own Whitewash
Skill Level: Novice
Time: 15 minutes
There are many different whitewash recipes. It is a simple project that takes about 15 minutes to complete. The most difficult part is deciding which solution to use. Mixing hydrated lime and water is the most simple and popular method. However, a salt water solution will also do the trick.
Step 1 — Measure
Measure out your 5 to 1 ratio of lime to salt. When you are making the mixture for the first time, only make enough to experiment with the product you plan to whitewash so that you can see the result before you tackle the whole project.
Before you start, take a minute to test your solution in an inconspicuous area. Keep in mind that your method of application could affect your choice. Also, pay attention to the surfaces to which you're applying the whitewash. Some surfaces may not react well to the lime mixture.
Step 2 — Add Water
Slowly add in the water. Bring your whitewash solution to the consistency of a creamy paste. Try not to go overboard and add tons of water all at once or you will end up having to measure out more hydrated lime and salt to balance it out.
Step 3 — Mix It Up
Use any stirring device that you are comfortable with. Be sure to get all of the dry pockets out of the mixture. Dry ingredients have a tendency to clump together and leave lumps, but you can control the texture by adding water slowly and stopping to stir the mixture before adding more.
The steps for mixing a whitewash recipe are quite simple, if you don’t achieve the desired result, there are many things that you can do to alter the outcome. You can let the solution sit overnight. You can add pigmentations to the mixture to get a different color or you can try a different recipe altogether. One simple thing you can try is omitting the salt.
You can also create whitewashes from paint. If you take the time to test your whitewash recipe, you will surely enjoy the results it brings to your project.
