Wearing gloves, dust mask, and goggles, mix the cement, peat, and perlite in a large tub or trough. (For quantities of all ingredients, see "The Recipe" on the overview page.) Add the water and acrylic fortifier a bit at a time, turning the mix thoroughly so it sticks together but is not runny. Fluff up the nylon reinforcing fibers and add them to the mix. You should be able to form the fiber-reinforced mix into a solid ball that doesn't fall apart.
