Full instructions on how to mix, apply, and finish limewash are available here.
Pour leftover limewash & water used to clean brushes, whisks, measuring cups, etc. into a designated 5 gallon bucket. As the hydrated lime & portland cement settle, pour off clean water and let harden for regular trash pickup.
DO NOT WASH BRUSHES, BUCKETS, ETC IN YOUR SINK.
This is portland cement and lime, people. Be smart. They don’t belong in sewer pipes or storm drains.
Time & money
– Limewash paint available at big box stores dries WAY too fast. A 10-40 minute window to paint an entire wall & spray it down before it’s too late is stupid fast.
REAL limewash can be sprayed or sponged off hours after application. I know. I rinsed an entire 20′ x 15′ wall off 8 hours later because I didn’t like how thick I put it on.
– Making limewash yourself is not only easy, but a fraction of the price of commercial limewash paint. You can make more whitewash from portland cement and lime than you could ever use in a lifetime at the same price.
Simple! Reduce the amount of lime putty.
For Greek island white, increase the lime.
White portland cement is available online but you can still whitewash your brick using lime and water. See the video at the end of this post for instructions.
It’s best on porous materials like brick, stucco, cement blocks, etc. It can be used on wood, but tends to flake off because wood moves so much depending on the weather.
For reference, 6 cups of limewash covered 130 sq ft of very rough nonuniform bricks.
Yes, but getting an even and perfect match will be difficult. It’s more of a natural, whimsical look vs an even coat of paint.
If you’re an experienced DIYer, I would definitely give adding powder pigments like this a try. When mixing it into the whitewash, do not add more than 5% by volume as it will fall out of suspension and be very splotchy.
Don’t panic. I whitewashed my brick patio when it was hot as hades with a fan on and the limewash dried in less than two hours. Way too fast for carbonation to take place.
I lightly misted the walls until they were damp, but not wet enough to remove the whitewash, every couple of hours for 2 days. Once I saw the finish crackling as I sprayed it down, I knew the lime had carbonated and I could start the next coat.
