Pros The cast stone elements then sit for 24 to 48 hours to properly cure and strengthen before being removed from the molds for final cleaning and preparation. Wet cast cast stone is produced by mixing the four common ingredients (sand, pea-rock, cement and water) together with carefully selected admixtures in a scientifically defined ratio and placing the mixture into professionally constructed precision molds. Good placement techniques including vibration ensure a quality finish. Many combinations of chemicals can be used to improve the performance of the mixture without having to dilute the mix with water. Professional manufacturers of cast stone products like Premier Precast have very strict ratios of ingredients as they strive to strike a delicate balance between creating a concrete mixture that is easy to work with for ornate molds and still meets the demanding requirements of ASTM C1364. If there is an undercut in your piece, you may have to make complicated multi-piece molds.Otherwise, you will have color issues and edge quality deterioration. It takes into account surface appearance, workability, surface defects (like bug holes), ease of casting and cost. The mix design of your concrete is important.Chemical release agents result in a better surface finish. Here’s a list of important considerations when making wet cast cast stone. Get your cake tin ready (mold) and pour in the cake mix batter (concrete mix meeting the requirements of ASTM C1364). Manufacturing wet cast cast stone is just like baking a cake. These two methods of making simulated natural stone are outlined below. The concrete mix for vibrant dry tamp cast stone has zero slump while the wet cast mix includes a higher water content and has 3” to 4” of slump. What’s the difference between wet and dry cast stone? The machine cast method of creating dry tamp cast stone is not discussed in this article. 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. Both of these methods create a simulated natural cut stone look. There are two common methods of manufacturing cast stone : one is the dry tamp method and the other is the wet cast process. ![]()
