JJRA delivers cutting-edge concrete protection and performance products designed for today’s toughest environments. Our signature line includes STAR MINERAL GUARD (TM) for a high gloss, stain resistant finish with easy application; STAR MINERAL 442, a deep penetrating treatment originally developed for bridge decks to combat corrosion, salt damage, and freeze thaw deterioration; and STAR MINERAL BLENDED DENSIFIER, an economical, eco friendly solution that hardens and dust proofs concrete surfaces with no rinsing or fumes. Whether you're working on infrastructure, industrial flooring, or architectural finishes, our products are built to last and easy to apply.
STAR MINERAL GUARD combines lithium chemistry with unique polymer chemistry to create a durable micro-coating with greater shine, stain resistance, and clean-ability. Simple application, low odor, quick cure time, high gloss (with burnishing).
USES: Polished concrete, masonry, stone, commercial concrete, offices, grocery stores, residential concrete, any concrete or masonry surface that will benefit from enhanced aesthetics, light reflectivity, and easier maintenance.
STAR MINERAL 442 was originally developed for highway bridge decks where deicing salts can cause deterioration and rebar corrosion. This versatile formula reduces chloride penetration, water intrusion, scaling, freeze-thaw damage, staining and efflorescing salts. Star Mineral 442 penetrates and reacts to become a permanent part of the concrete, so it doesn't peel or wear off.
USES: Star Mineral 442 is perfect for garages, parking structures, sidewalks, driveways, warehouses, loading dock areas, decorative concrete, business entries, restaurants, schools, retaining walls, nearly any concrete. It also works well on pavers and manufactured stone.
STAR MINERAL BLENDED DENSIFIER combines advanced lithium silicate with colloidal silicates to create an economical densifier that hardens, densifies, and dust proofs concrete and other porous silicious materials. Star Mineral Blended Densifier penetrates and reacts to become a permanent part of the concrete, so it doesn't peel or wear off. Easy, no-rinse application, no noxious odors or fumes.
USES: Star Mineral Blended Densifier is perfect for industrial concrete, masonry, interior or exterior, and promotes durability. Star Mineral Blended Densifier also creates the perfect base for colored concrete, concrete polishing, and concrete that will receive a Star Mineral Guard Treatment.
Key Benefits of Lithium Li2 in Concrete Finishing:
1. Deep Penetration:
Lithium silicate molecules are smaller than sodium or potassium silicates, allowing them to penetrate deeper into the concrete surface. This results in longer-lasting hardening and densification.
​
2. Reduced Efflorescence:
Lithium compounds are much less reactive with carbon dioxide and moisture, reducing the chance of efflorescence (the white, chalky deposits on concrete).
3. Increased Durability:
The lithium-based reaction creates a strong, durable matrix that resists abrasion, water penetration, and chemical damage.
4. Faster Cure & Minimal Residue:
Lithium silicates dry and cure faster than other silicates, and they leave less residue, reducing the need for rinsing or scrubbing.
5. Stability in Harsh Conditions:
Lithium compounds are chemically stable, so they don’t break down or degrade easily under UV exposure, freeze/thaw cycles, or heavy traffic.
