  • Stucco

    was curious to know if others in the past have mixed their own stucco or purchased it pre-mixed to finish the oven. I think I would like to mix my own(since I already have portland cement) and was curious if the following is the correct "recipe" that can withstand the heat of the oven:
    For a scratch coat, you will need this mixture:


    1 part portland cement

    1 part hydrated lime

    2 1/2 to 4 parts sand


    For a brown coat, you will need:

    1 part portland cement

    1 part hydrated lime

    3 1/2 to 5 parts sand


    Finish coat ingredients:

    1 part portland cement

    1 part hydrated lime

    1 1/2 to 3 parts sand

    I am also confused if I am suppose to mix a scratch coat, brown coat or Finish Coat. Or all three?

    I am also curious if a Finish Coat serves the same purpose as Stucco Paint? Or does the Stucco Paint prevent moisture from seeping in?

    I apologize if I am repeating questions, but I greatly appreciate any advice. I have never worked with Stucco before.

    -Hope
Working...
