Does Stone Coat Epoxy Turn Yellow?
Does Stone Coat Epoxy Turn Yellow?
Yes. Stone coat epoxy can turn yellow over time if it’s not properly sealed. The yellowing is caused by the epoxy seeping out of the cracks in the coating and reacting with the air.
This can make the epoxy discolored and brittle. If the yellowing is severe, it can damage the coating and lead to leaks. To prevent yellowing, seal the cracks in the epoxy coatings with a sealant.
However, if the yellowing has already occurred, there is no way to reverse it. Stone coat epoxy that has turned yellow will have to be replaced.
Additionally, Stone coat epoxy turns yellow as a result of chemical reactions that take place between the epoxy and the stone. Epoxy is a two-component material composed of two main ingredients – epichlorohydrin and polyester resin. In the presence of moisture, epoxy can react with the stone to produce a yellow coating.
The reaction between epoxy and stone is a chemical reaction between the two substances. The epoxy molecules link together to form a network that can absorb water and other chemicals. This process can cause the epoxy to turn yellow and produce other chemicals that can damage the stone.
Stone coat epoxy is a great foundation coating but not an exterior finish. If you want your stone coat epoxy system to last for years without any problems, make sure you seal the cracks in the system with proper sealant.
Is Stone Coat Epoxy Scratch-Resistant?
Yes. Stone coat epoxy is very scratch resistant. However, the scratch resistance comes from the epoxy and does not come from any other coating. If an outside scratch occurs, it will scratch the epoxy stone coat.
However, just because your stone coat epoxy system is scratch resistant doesn’t mean it’s immune to chipping. Stone coat epoxy can chip off and leave small chips on the surface of the stone as a result of rock strikes to the surface of the coating. That’s why you need to seal the cracks in your coating with a proper sealant.
Stone coat epoxy is a very hard coating, but it’s not scratch resistant in the traditional sense. When you scratch a surface made of stone coat epoxy, you’re scratching the polyester resin that makes up 90% of the epoxy system and not the epichlorohydrin resin that makes up 10%.
Stone coat epoxy is not designed to prevent scratches, instead, it is designed to protect the stone from weather and environmental damage.
If you’re planning on using stone coat epoxy for an exterior application, make sure you seal the cracks in the system with a proper sealant so that it does not turn yellow. Otherwise, your stone coat epoxy will turn yellow over time and will have to be replaced.
Is Stone Coat Epoxy Eco-Friendly?
Yes. Stone coat epoxy is a very eco-friendly product. It is made using 100% renewable resources that are either recycled or grow naturally in the ecosystem.
Even though it is a plastic coating, Stone coat epoxy does not contain any fossil fuels or petrochemicals. Instead, it is made from natural ingredients that are environmentally friendly and sustainable for years to come.
Stone coat epoxy is biodegradable and eco-friendly because it’s made from renewable resources such as corn starch and wheat flour. The ingredients are both naturally occurring in nature.
They can be produced with minimal impact on the environment as opposed to synthetic materials used in traditional epoxy systems. However, just because Stone coat epoxy is biodegradable and eco-friendly doesn’t mean it’s immune to the disadvantages of other plastic coatings.
Stone coat epoxy is still a plastic coating, meaning it will take decades before it completely breaks down by natural processes. Some of the chemicals in stone coat epoxy are known to cause skin irritation and lead pollution and are carcinogenic.
Stone coat epoxy contains phthalate plasticizers that have been found to cause cancer in laboratory animals exposed to the chemical for a long time. That’s why you must ensure that you use stone coat epoxy in a well-ventilated area and always wear protective clothing when handling the material.
