Dur-A-Seal LS-14 Concrete Refractory & Chemical Hardener compound is a ready-to-use, colourless liquid. Dur-A-Seal LS-14 offers substantial improvement in abrasion and hardness, and will significantly improve the durability of the concrete surface when compared to untreated concrete. When applied, it penetrates into the concrete surface and a chemical reaction takes place, producing a by-product that fills in the pores of the concrete. This process produces a substantially denser concrete surface with enhanced durability. In addition to this action, Dur-A-Seal LS-14 also solidifies concrete, eliminating dusting and pitting as well as prevent efflorescence.
- Formulated using Lithium Silicates, which outperforms Potassium and Sodium Silicates, due to highest Lithium oxide (8.1) ratio.
- Superior efflorescence resistance than standard Silicates.
- Zero VOCs.
- Penetrates deeply into concrete to increase density and harden surfaces to help prevent entry of moisture and other foreign matter.
- Dustproofs and improves chemical, petroleum and abrasion resistance of treated surfaces.
- Provides a permanent, attractive sheen with the ability to polish.
- Protects against scratching or peeling.
- Provides tough, protected surface that will not yellow, discolour or show pedestrian or vehicular traffic wear marks.
- Improves light reflectance.
- Ready to use and easy to apply.
Dur-A-Seal LS-14 Concrete Densifier & Chemical Hardener is recommended for use wherever hardened, dustproofed and improved adhesion, abrasion-resistant surfaces are required. Dur-A-Seal LS-14 is very suitable for concrete polishing. It may also be used to harden old masonry walls to be coated by paints or cement-based aggregates.
