What is dry and wet cast stone?

Two common methods of manufacturing cast stone: Dry tamp method and wet cast process. Both of these methods create a simulated natural cut stone look. The most common finish for a dry tamp cast stone is limestone or sandstone while the wet cast method is capable of providing a wider array of possible finishes.

Best way to describe Wet casting is like baking a cake. Where the tin is your mold and the concrete mix is the batter. Important considerations to wet casting: the current concrete mixture is essential and mold must be in perfect condition to prevent any leak in the mold which will cause discoloration and quality deterioration. The mold release is very important to prevent surface defect and to have the best surface finish results. Then cast stone must sit for so many hours to properly cure and strengthen before removing the molds.

On the other hand, dry tamp use hand tampered method where the dry concrete mix is hand tampered into the mold. This method gives the cast stone more of a refined and detailed look of limestone/ sandstone finish. Dry casting has faster demold time, and mold can be use several times a day, no treatment is required afterwards to achieved the limestone look, and repairs after demolding is relatively easy.

Dry tamp replicate a carved stone while wet cast looks like a molded product where details does now show as well as dry cast. Also, dry cast can only achieve limestone or sandstone texture and cannot create a smooth finish. Wet cast product is better when a structural product is needed and where bigger pieces need to span large opening.

WHAT IS A CAST STONE

Cast stone or reconstructed stone is a concrete masonry form of artificial stone that simulates natural cut stone used in unit masonry applications. Cast stone is an excellent replacement for natural cut limestone, brownstone, sandstone, blue stone, granite, slate, coral, travertine, and other natural building stones as well as terra-cotta. It is used for architectural features: trim, or ornament; facing buildings or other structures; statuary;  garden ornaments. Cast stone can be made from white and/or grey cements, manufactured or natural sands, crushed stone or natural gravels, and colored with mineral coloring pigments to achieve the desired color and appearance while maintaining durable physical properties which exceed most natural cut building stones.

Brief History of Cast Stone:

The earliest known use of Cast Stone dates about to the year 1138 and extensively used in London in the year 1900 and have gained widespread acceptance in America in 1920.

Today, Cast Stone have become a truly superior alternative to natural stone product. Its versatility and ability to simulate or reproduce almost limitless variety of natural stones combined with strength and weathering qualities, and ability to replicate with consistency makes cast stone an ideal material for building, remodeling, and restoration.
