For anybody who has built Styrofoam fake rocks, where did you get your grout?
I built fake rocks structures, but used Wall Mud because all the grout I saw was $20+.
Is this how much it usually is?
I got it at Lowe's and it ran about 15$ for an 8lb box of it if I remember correctly. Keep in mind that I only used about 2 cups worth of grout for two rocks though so I still have PLENTY left over.
