Made of acrylic, SATIN LOOK (JS) Protector is specially designed to protect concrete pavers and to stop the movement of aggregates or sand (conventional paver joints) while slightly enhancing the original color of pavers. It prevents deterioration caused by chemical products such as de-icing salts, while providing resistance to acids and alkalis. Its transparent film stops the penetration of contaminants, facilitating the maintenance of pavers. Water-based, SATIN LOOK (JS) Protector does not release unpleasant fumes and is environmentally friendly.
