CETEX LPD: Liquid Potassium Densifier & Hardener

CETEX LPD is a concentrated potassium silicate-based chemical designed to permanently harden, dustproof, and densify a wide variety of cementitious surfaces. By penetrating deep into the concrete matrix, it reacts with free calcium hydroxide to fill pores from within, creating a breathable yet impenetrable surface.

• Superior Hardening: Dramatically decreases surface porosity and increases abrasion resistance.
• Advanced Curing: Traps moisture within wet concrete to ensure a slow, strong, and complete curing process.
• Anti-Efflorescence: Far more stable than sodium silicates; it will not produce unsightly white salt powder (blooming).
• Permanent Sheen: Improves light reflectance and develops a lasting, attractive luster when polished.
• Tough & Trace-Free: Provides a protective shield that resists pedestrian and vehicular wear marks without peeling or scratching.
• Chemical & Water Resistant: Restricts water passage through pores and improves resistance to chemical spills.
• Economical Concentration: Supplied in concentrated form to reduce transportation costs and simplify large-scale applications.

The substrate must be clean and structurally sound. Remove all existing coatings, curing compounds, or oils. Repair cracks and holes. For maximum reaction, the surface should be dry to allow the LPD to "wick" into the pores.

• Dilution: Mix CETEX LPD with water in a 1:3 ratio.
• Method: Apply using a low-pressure sprayer or spread evenly with a soft-bristled broom.

Keep the surface wet with diluted LPD for at least 20 minutes. In hot or windy conditions, pre-dampen the concrete to prevent "flash drying." Once dry, remove any powder residue with a stiff broom or scrubber.

Pro Tip: For an immediate mirror-like shine, dry-buff the surface with a high-speed burnisher and a polishing pad.

Apply from the bottom up using a "wet-on-wet" technique. Re-apply within 3–5 minutes of the first coat. Continue until the surface stays moist for at least one minute before the solution is absorbed.

Restrict heavy usage for 12 hours to allow the chemical reaction to stabilize.
