Whitewash paint is easy to prepare and apply. It has been used for many years for painting different structures around the world, both interiors and exteriors. Several additives are mixed with it to give it special properties or a color. This paint is inexpensive, but it is not preferred for interior walls, because it has a slight tendency to stick to clothes.
Whitewashing is quite an easy job. But, don't use rollers when whitewashing walls, as it doesn't give the same consistency. Instead use a brush to paint the whitewash on various surfaces. Whitewash can be used for exterior painting and also on interior surfaces. When it comes to interior surfaces, it is used to paint ceiling and walls of a barn. It is a very effective solution for keeping the dark interiors of the barn brighter and cleaner. Furniture whitewashing can also be done, and since it is inexpensive, it can be done again and again. When painting with whitewash, clear out the area of important items, and cover the fixtures with plastic sheet, and then apply only a single coat of the paint. This is an important technique and should be remembered. The whitewash upon drying will get more opaque, and after it cures, it will get even more opaque.
How to Make this Paint?
To create a small batch of whitewash paint, mix 2 pounds of lime powder and around 1 gallon of water together. The water activates the lime, and the reaction starts to produce heat on its own. So, you don't have to use boiling water for making this paint. Then, mix thoroughly and let the mixture sit for about 24 hours. Now, in another container mix 2 pounds of salt and 1 gallon of water, and set it aside. After the lime is ready, mix the salt mixture in it. The consistency of the final mixture will be very thick, and if want a thinner whitewash, you can add some more water. Mix everything well, and let it sit for another 24 hours. Then, apply it to the exterior house paint.
The above method of making whitewash is an easy, basic home improvement DIY project, which is good enough to do a decent job. But, you can add different additives to create a whitewash having different properties. Additives like water glass, glue, salt, soap, milk, flour, earth, egg white, and blood have been used in the whitewash paint recipe. Adding earth can help create different shades of whitewash paint, like cream, yellow, and browns. Sometimes, linseed oil is added to let the whitewash adhere to difficult surfaces. Cement is added to create a harder wearing gray or white paint. Many times, diluted glues are used to improve the toughness of the paint.
With a simple recipe, you can create a whitewash, and use it for painting various surfaces. However, avoid it on the interior walls, as it will stick to your hands and body. But, one can use this inexpensive paint for exterior walls, and you can also apply it on wood, for painting fences, and other objects.
