Episode 27
Hello my friends, welcome back everyone!

Today, I will show you all how I used a second acid stain color to camouflage the mistakes I had with my acid stain!

My concrete is very fresh, porous, and has a rough brush finish. In addition, here on the surface of Mars, it has some small cracking called "Plastic Shrinkage Cracks."

These concrete imperfections lead to some strange puddling that complicated how our acid neutralized - There are a bunch of ugly dark marks around the cracks. Knowing how the acid and ammonia behave around these cracks now, I will scrub in another acid stain color around the ugly areas and make sure the ammonia is worked in after the acid is done burning.
