Instructions

Step 1

 Hypertufa Step 1: Mix dry ingredients

Measure ingredients in a 1:1:1 ratio in proportion to the volume of your container. Combine Portland cement, perlite (or vermiculite), and peat moss in a large tub or container. Mix ingredients well with your hands before adding 1 part water.

Always wear gloves and a mask when mixing. Remove any large pieces and break up any chunks so they will mix well with the water.

Step 2

Hypertufa Step 2: Add water

Add water slowly, and mix it in well. Avoid getting the mix too wet.

Step 3

Hypertufa

The proper mixture should have the consistency of cottage cheese - when you squeeze the mix in your hand, it should stick together and a little water should drip from it. Let the mixture sit for 5-10 minutes.

Step 4

Hypertufa

Spray the inside of the 5-quart pail with nonstick cooking spray. Press a little of the mixture into the bottom of the mold. Add more of the mixture, working your way up the sides.

Step 5

Hypertufa

Once the sides are covered with the mixture, insert the 2.5-quart pail into the middle of the 5-quart pail to create a pot. Spray the outside of the 2.5-quart pail with nonstick cooking spray before inserting it into the mixture.

Step 6

Hypertufa

Tap around the outside of the container with a rubber mallet to move large bubbles to the surface. Smooth any lumps around the top edge with your hands to get the desired shape.

Step 7

Hypertufa

Wrap the hypertufa with a plastic bag to hold in the moisture as it cures. Let it set up for 24 to 36 hours before gently removing from the mold. Set in a dry place for two to three weeks to finish drying.

Step 8

Hypertufa

Once the hypertufa pot has cured, tap the sides of the container with the rubber mallet to loosen the container.

Step 9

Hypertufa

The pot will lighten in color as it cures to a light gray. File or sand the edges for a smoother finish. Use a drill and a 3/8" bit to create a drainage hole in the bottom of the pot.

Expand on this basic technique to make interesting hypertufa structures. Change your molds to make larger or smaller pots. Give a pot texture by choosing molds with designs, or add items - such as dowel rods - to the hypertufa mixture.
