3D Aquarium Background

Step 7: 1st Coating

This step is the first in coating your background.  You want to mix the concrete ALMOST water thin.  Sort of like runny pancake batter.  I used a concrete overlay called Ultra Tex U-91-1 but others have used regular concrete and the quickcrete overlay stuff.  What ever you use make sure its doesn't have a lot of stones in it or you will be sorting through it to remove them.  You want a smooth mixture and real watery.  This first coat will only be the base and give the additional coats something to stick to.  You dont have to add color to this coat but I was playing with the color mix to figure out what I wanted for the rest of them.  Once you mix it up just use the cheap throw away brushes and brush it on like paint.  I poured some on then used the brushes to spread it around even.  Dont worry if it looks a little thin, the second and 3rd coats make it thicker and cover what this coat doesnt.  Let this coat dry for at least 24 hrs, more the better
