Information

Lithium-based concrete sealer

Lithium-based concrete sealer is a sealing, dustproof, wear-resistant hardener. As a new-generation lithium-ion water-based product, it is colorless, odorless, non-toxic, and flame-retardant. By effectively penetrating 5–8mm, it reacts with free calcium/magnesium ions in concrete, forming a 3D network structure. This consolidates concrete components into a solid entity, creating a dust-free, dense whole. Capillary pores are permanently sealed, preventing dust emission while enhancing strength, density, and abrasion resistance.

Main components: Lithium silicate, etc.

Packaging: 20kg/barrel.

Barrel dimensions: height: 384mm, top diameter: 300mm, bottom diameter: 270mm, inner mouth diameter: 292mm.

Scope Of Application

Ideal for all venues requiring high strength, wear resistance, easy cleaning, and long-lasting aesthetics.

1. Industrial: Workshops, warehouses, heavy machinery zones, pharmaceutical/food plants (emphasizing cleanliness).

2. Commercial: Malls, shopping centers, parking garages, showrooms, 4S stores (emphasizing gloss).

3. Public facilities: Airports, stations, schools, hospital corridors (emphasizing durability & easy cleaning).

4. Others: Old floor renovation, sandy surface repair.

Product Features

1. Marble-like hardness, permanent dust/sand resistance, stain-proof & easy cleaning, lasting gloss, low maintenance costs.

2. Extreme hardness: Mohs hardness 8–9 (close to granite), 8x higher abrasion resistance than ordinary concrete. Withstands forklifts and heavy loads.

3. Permanent dustproofing: Seals pores completely, eliminating sanding/dusting for a clean environment.

4. Dense & impermeable: Blocks water, oil, and liquid stains effectively for easy cleaning.

5. Sealing & reinforcement: Enhances structural integrity, reduces cracking risk, extends lifespan (up to 30 years).

6. Enhanced gloss: With polishing, achieves marble-like luster (options: matte, semi-gloss, high-gloss).

7. Eco-friendly & safe: Non-toxic, odorless, ready for use after application.

8. Cost-effective: One-time investment, long-term benefits. Slashes cleaning, waxing, and renovation costs.

Construction Process

1. Substrate preparation (Critical): Clean, repair cracks, remove laitance/old coatings. Apply after 14-day curing when concrete strength ≥20MPa.

2. Coarse grinding: Use professional grinders to open concrete pores for penetration.

3. Apply sealer: Spray evenly on sun-dried surface. Soak for 2–3 hrs at 25°C until viscous and dry.

4. Fine grinding: Water-grind with 500-grit discs uniformly.

5. Apply sealer: Spray evenly on sun-dried surface. Soak for 2–3 hrs at 25°C until viscous and dry.

6. Fine Grinding and Polishing: Sequentially use resin abrasive discs of different grit sizes for fine grinding, superfine grinding, and polishing to gradually enhance the glossiness (until the desired effect is achieved).

7. Cleanup & curing: Clear debris, ready for use after 24–72 hrs curing.

Flooring Performance Comparison

Parameter Comparison: Lithium Hardener Floor vs. Ordinary Epoxy Floor
Parameter	Lithium Hardener Floor	Ordinary Epoxy Floor	Performance Gap
Mohs hardness	8.0–9.0	1.0–4.0	Lithium: 2–8x higher
Abrasion resistance	Abrasion resistance ≥6.3 (ASTM D4060)	Abrasion resistance: Level 2–3	Lithium: 2–3x higher
Compressive strength increase	40% increase at 28 days	Depends on substrate; intrinsic strength ≤30 MPa	Lithium significantly strengthens substrate
Service life	15–30 years (semi-permanent)	3–5 years (requires refinishing)	Lithium: 3–10x longer
Chemical resistance	Resists 60% H₂SO₄, saturated NaOH (no change in 3 days)	Resists 40% acids/alkalis (some products resist strong acids)	Lithium more stable
Penetration depth	5–8 mm (permanently sealed pores)	Surface coating (0.2–0.5 mm)	Lithium penetrates substrate
Dustproof activation time	Dust emission reduced to zero in 2 hrs	Effective after surface dry (~4 hrs)	Lithium faster
VOC content	0 g/L (water-based, eco-friendly)	Solvent-based: 200–300 g/L; Water-based: ≤50 g/L	Lithium absolutely eco-friendly
