Find a premium lithium densifier, hardener, and sealer

Pentra-Sil (HDS) is an eco-friendly, high performing lithium densifier, sealer, and hardener that works hard at restoring worn and/or damaged flooring to bring it back to its former glory. It will enhance and protect dyed, stained, and integrally colored surfaces and is easy to use–no rinsing is ever required. It fights off moisture, stains, and other harmful substances to ultimately protect and prolong the life of your concrete surfaces making them much more durable and hardy. 

  • Description
  • Our densifiers are high-performing concrete densifiers using innovative lithium-silicate technology. They don’t leave any film on your concrete surfaces but rather penetrate deep into the top few layers of your concrete to seal pores and irregularities from inside your concrete. Lithium densifiers contain smaller molecules thus making the reaction more even and consistent. They create much stronger and denser surface profiles thus saving on maintenance costs later on. 

  • Features
  • Lithium densifiers and sealers penetrate the concrete and harden from the inside out. They reduce dusting and efflorescence and react quickly with the concrete resulting in a faster concrete polishing process. They reduce water absorption and surface staining and enhance the color of your concrete. They help solidify and strengthen both old and new concrete surfaces for a much longer life thus saving costs.

  • How to choose between concrete densifiers
  • Budget constraints may play a factor when choosing a concrete densifier because some densifiers eg) sodium-based densifiers, are initially more affordable to apply but may not end up saving you in the long term due to higher maintenance costs. These factors need to be weighed up before making your final decision. 

  • How to apply concrete densifiers
  • To best apply a concrete densifier, spray the floor with the lithium densifier for a minimum of 20 minutes– remove any excess product. Do not let the densifier ‘pool’ and aim for an even and strategic distribution of densifier to your concrete surface.
