Polished Concrete - Polished concrete creates a high-end aesthetic that is great for show rooms and other spaces designed to wow visitors. While visually appealing, polished concrete is easy to stain and etch, so it must be protected to maintain its aesthetic. Premera Sol Gels bond directly to polished concrete without the need to grind or profile which significantly speeds up installation. Premera Sol Gels provide excellent chemical and stain protection, and are also highly abrasion resistant and easy to clean which creates a durable, low maintenance and easy-clean floor finish.
