LiON HARD® is a VOC-free, environmentally friendly lithium silicate concrete floor densifier and hardener. This product penetrates bare concrete surfaces and transforms them into a permanently dust free floor with a prideful gloss that gets better with age. There’s no scrubbing, no washing, and L&M’s Water Saver Technology makes LION HARD environmentally friendly and easy to apply. This product may be applied to new and existing, cured concrete as a chemical hardener, dustproofer and densifier to improve surface durability and appearance. LION HARD is also very effective on polished concrete surfaces to harden, densify and protect their attractive and durable finish.
