= Limewash: Pros and Cons of Popular Brick Exterior Treatments =
Do you have visibly aging brick? Are you considering a new exterior on your brick home, but not sure how to change the color or appearance of your brick?
Although brick is one of the oldest and most stable building materials, it doesnât always age well
Bricks that are chipped or worn around the edges arenât the look everyone is going for. There is also the genuine problem of dated brick facades for many homeowners
How do you give your house an update that doesnât cost many thousands of dollars in this situation?
In two previous posts, we weighed the pros and cons of painting your brick exterior. We also introduced another technique for brick walls called German Smear, or mortar wash
Mortar wash is a permanent treatment that changes the texture of your brick exterior, and itâs affordable and DIY friendly
However, there are two other options you could use to create a similar look to German smear: limewash and whitewash
So, today, letâs take a close look at limewash: what it is, how great it is for your bricks, and how easy it is to use
== Limewash is Ancient & Eco-Friendly ==
Limewash has been around for as long as porous building materials like brick and stone. The ancient Egyptians used it on their pyramids
Limewash is a thin coating with a consistency similar to paint, but it couldnât be more different
For one thing, limewash is natural. It is made out of limestone that has been crushed, burned, and made into a putty with water
The putty isfurther thinned, and then mixed with natural pigments if a color other thanis desired
This type of natural paint is a favorite of Belgians and other Europeans for use on their interior stone walls as it is anti-microbial, improves air quality, and is free of solvents that harm the environment
Limewash creates a chalky, mottled finish that adds depth and beauty to any wall it is applied to
Historically, limewash has been used only on porous surfaces, because it doesnât sit on top of the surface, but sinks in
However, with the right bonding primer, modern limewash paint can be used on your drywall interior walls
== Limewash is Versatile ==
Limewash is especially helpful for homeowners who dislike the color of their brick, but not necessarily the texture
Because it will sink in, it doesnât change the texture of your brick. This is good news for the brick since they need to breathe, and paint isnât always the best option
Limewash helps to protect your bricks and mortar from the elements. It comes in a range of earth-tone colors. However, the range is a bit limited
Since lime is highly alkaline, the pigments have to be able to resist the high alkali. Grays, browns, and taupes are the normal range of colors for limewash paint
You can also create an antiqued effect similar to mortar wash using limewash paint, simply by wiping the paint off of select bricks as you work
Limewash is easy to apply with a large masonry brush, and itâs opaque so you can control the depth of color with the number of layers of paint you choose to apply
In addition, limewash will fade over time, so it needs to be re-applied, but it wonât chip and flake like paint
== Limewash is Inexpensive & DIY Friendly ==
Just like its companion mortar wash, limewash is one of the cheapest materials you could find to cover your entire home exterior
You can mix your own limewash using lime putty from hydrated lime. You can find this at a hardware store for $3-$5 for a 50 lb. bag
Even if you order a bag online, it is less expensive than a bucket of paint at around $40 for a bag. With this much limewash and some supplies, you could coat an entire 1600 square foot house
== Downsides to Limewash ==
The limited range of colors is one downside, as is limewashâs opacity if you want the job to be done in one step
The other downside is that it can be tricky to match the consistency of limewash batch to batch if you are mixing your own. This difference can result in a noticeable line on your wall or house
The best way to solve this problem is to mix more than you think you will need in a large, sturdycan and save the extra with a tarp, and a lid snapped on tight
