Product Information

NOTE: One gallon of sealer can cover up to 200 square feet. This will depend on the porosity of the stone/surface as well as the application process.

TSSPRO-CD2 Lithium Densifier/Hardener Plus Water Repellent for Concrete and Concrete Products

NOTICE: This product is VOC Compliant.

DESCRIPTION Densifier Plus Repellent (TSSPROCD2) is a state-of-the-art premium densifier, hardener and water proofing sealer for new and existing concrete surfaces.  TSSPROCD2 is a multi-phase penetrating lithium colloidal based proprietary silicate treatment that reacts with the concrete to produce insoluble calcium silicate hydrate that locks aggregate together and fills vacant concrete pores while building a water-resistant matrix.

  • Available in 5-gallon pails
  • Water resistant
  • Improves the performance, appearance and light reflectance of new or old concrete
  • Perfect for diamond polishing
  • Provides superior abrasion resistance
  • Can greatly extend the life of decaying and deteriorating concrete and cast stone products
  • Prevents freeze/thaw concrete cracking


TSSPRO-CD2 like CD1 reacts with concrete to produce insoluble calcium silicate hydrate within the concrete pores that locks aggregate together and fills vacant concrete pores.  In addition, it builds a superior water-resistant matrix. TSSPROCD2 integrally waterproofs, densifies, strengthens and preserves concrete of any age at any point during the concrete’s useful lifespan.

Features & Benefits

  • Penetrates and reacts quickly to produce better initial and ultimate hardness.
  • Easy, one step application.  No flushing, no scrubbing, no caustic wastewater.
  • May be applied to broom finished, steel troweled, power troweled or burnished concrete finishes.
  • Provides superior abrasion resistance than conventional hardeners.
  • Produces a fast surface gloss which improves with traffic and maintenance.
  • Improves performance, appearance and light reflectance of new or old concrete.
  • Reduces application time and costs of diamond polishing operations
  • Will not contribute to surface crazing. High lithium content combats surface ASR.
  • Gloss and hardness do not reduce slip resistance.
  • Will not absorb water or contribute to floor sweating.
  • Breathable and UV stable. Will not yellow, discolor, peel or flake.
  • VOC Compliant. Non-flammable. Non-toxic. Low odor.
  • Cures quickly. Most floors can be opened to traffic within one hour of treatment.
  • Treated surface are easy to maintain and require no waxing.

Advantage of Using TSSPRO-CD2

TSSPRO-CD2 is safer, easier and faster to apply than conventional sodium or potassium silicate-based products and it is water repellent.  It can be applied with a low-pressure pump up sprayer, mop or a soft-bristled push broom. In addition to greatly increased surface hardness,TSSPRO-CD2 reduces dusting and simplifies maintenance producing a cleaner, healthier environment for years. TSSPRO-CD2 is VOC compliant.

TSSPRO-CD2 should only be applied on concrete surfaces and products containing cement.
