FREE SHIPPING from Diamondblades4us

RSP Densifier LS is a high-performance lithium silicate concrete densifier designed to deliver maximum hardening and long-term durability. It is ideal for freshly placed concrete, tilt-up construction, existing concrete slabs, and cementitious overlays. This fast-reacting formula strengthens concrete from the inside out with a simple one-coat application.

RSP Densifier LS penetrates up to ¼ inch deep into the concrete, where it reacts with free lime to form insoluble calcium silicate hydrate. This reaction significantly increases surface density, improves abrasion resistance, and creates a harder, dust-free surface while extending the life of polished concrete finishes.

Key Benefits:

  • Increases abrasion and wear resistance

  • Deep penetrating lithium silicate formula

  • Reduces dusting, sweating, and efflorescence

  • Will not promote surface crazing

  • Extends the life of polished concrete

  • Improves stain resistance and surface durability

  • Dustproofs concrete floors of any age

  • Compatible with integral color, stains, and dyes

  • Reduces long-term concrete maintenance

Coverage

Application Basics

  • Always test a small area first

  • Surface must be clean, dry, and absorbent

  • Apply when surface temperature is above 40°F (4°C)

  • Cool hot concrete (over 90°F) with light water mist to prevent flash-drying

  • Do not dilute

  • Mix well before use

New or Existing Concrete

  • Clean surface thoroughly before application

  • Apply with a low-pressure sprayer in a saturating coat

  • Spread puddles with a broom or microfiber pad

  • Keep surface wet for at least 20 minutes, adding product as needed
