Chemstone CS Mastic Soft is a high-quality, soft grade polyester mastic designed for bonding, filling, and repairing natural and artificial stone surfaces such as marble, granite, travertine, and engineered quartz.
Formulated with advanced resin technology, it provides excellent adhesion, smooth application, and easy polishing, making it ideal for professional stone finishing and restoration work.
Its creamy, non drip consistency allows for effortless use on vertical and horizontal surfaces, while the cured product can be polished, cut, or machined like natural stone.
