Variations of Hypertufa Recipes

A hypertufa is an artificial rock that is made up of various aggregates that is merged together employing Portland cement. Since they are very permeable and lightweight, they’re usually designed as garden decorations, usually as planters. A hypertufa is an substitute for tufa, a steadily precipitated limestone deposited from springs.

There are lots of recipes for producing hypertufas, although the fundamental formula is that it is one part cement for every three parts aggregate. For the most standard recipe, the main ingredients are 1 part Portland cement, 1 1/2 parts perlite, and 1 1/2 parts peat moss. Portland cement is available in two colors: gray or white. Gray is fine for most projects; meanwhile opt for white if you want a granite look to the end result or if you need to use colorants. Peat moss is included in the recipe as when it decays, it will leave openings and crevices that imitates the characteristic of a true tufa rock. At the same time perlite is the material that makes a hypertufa light.

Rather than perlite, you can replace it with vermiculite, although you may have a harder time finding one. Vermiculite will add a little more weight to your hypertufa. Additionally, it gives a glimmering effect to your hypertufa. The proportion of materials is identical with the first recipe.

Sometimes you might want to produce a stronger, heavier hypertufa. This can be done with the addition of sand to your mix. Be aware that the type of sand will affect the texture and color of the outcome of your project. For the proportion of this recipe, make use of an equal ratio for all the ingredients. Another additive that can be included to fortify your hypertufa is fiber mesh. For this recipe you need to use 2 parts of Portland cement, 2 parts perlite, 1/2 part coarse sand, 1 1/2 parts peatmoss, and just a tiny amount of nylon fiber mesh.

Peat moss may also be replaced with coir, a processed coconut fiber. The recipe for this variation is 2 parts portland cement, 2 parts coir, and 1 1/2 parts perlite. Consider that coir doesn’t decay as quickly as peat moss and as a consequence this recipe may not look like a real tufa rock, in contrast to those containing the latter.

You may also use hypertufa as a mortar, to combine genuine or faux rocks. For this purpose, you will require builders sand, clay soil, and acrylic fortifying additive. Black potting soil can also be used as a substitute for peat moss. The recipe is 1 part Portland cement, 1/2 part peat moss or black potting soil, 2 parts builders sand, and the acrylic fortifying additive.

As a final note, the key to every recipe is the appropriate adding of water. Add water slowly until you achieve the required consistency of your mix. You can always add more water anyway if you figure out that it is not enough.
