Achieve industrial-grade precision and prevent peeling or cracking with a systematic approach to substrate priming and self-leveling application.
To correctly learn how to use self leveling concrete, one must first understand that the quality of the final floor depends entirely on the interface layer. A proper primer balances water absorption and seals the voids.
Using LANGUAN 690 creates a strong bonding layer that prevents peeling and hollowing in subsequent decorative or self-leveling layers.
The interface agent seals porous substrates, ensuring that the self-leveling concrete doesn't dry too quickly, which would cause cracking.
It consolidates loose base materials and seals voids, creating a stable foundation for high-traffic commercial floors.
Works on precast concrete, polished mortar, wood boards, and gypsum layers with adjustable dilution ratios.
Effective pore sealing prevents air bubbles from rising through the self-leveling layer, eliminating surface pinholes.
By balancing water absorption, it reduces shrinkage stress in the concrete, preventing subsequent cracking.

Challenge: Porous concrete floor causing self-leveling bubbles. Solution: Applied LANGUAN 690 at 1:1 ratio. Outcome: Void-free smooth surface for epoxy coating.
Challenge: Loose polished mortar base. Solution: Undiluted priming treatment. Outcome: High-strength bond for decorative marble tiling.
Challenge: Old concrete with uneven water absorption. Solution: 1:3 dilution for deep penetration. Outcome: Consistent drying time for self-leveling concrete.
Challenge: Compact wood boards as flooring base. Solution: Undiluted interface agent. Outcome: Prevented delamination of subsequent mortar layers.
Challenge: Gypsum layer peeling. Solution: 1:3 ratio priming. Outcome: Strong bonding for surface coatings and decorative finishes.
Challenge: Severe porous cement mortar. Solution: Dual-layer priming with 1:3 ratio. Outcome: Waterproofing effectiveness and stable self-leveling base.
Requires undiluted application to ensure maximum bonding on dense, non-porous precast surfaces.
Balances water absorption of old terrazzo slabs to prevent peeling of new leveling layers.
Utilizes 1:3 dilution to seal deep pores, critical for waterproofing and self-leveling success.
Ensures smooth plaster application on dense concrete walls by creating a balanced adhesive layer.
Pre-treatment for cement fiberboard ensures surface coating doesn't peel or hollow over time.
Priming the base before tile sticking ensures no hollowing and maximum longevity of the finish.
All batches are tested for consistency in viscosity and bonding strength to ensure predictable field performance.
Stored in cool, dry, and frost-free environments, our interface agents maintain a shelf life of up to 24 months.
Comprehensive safety guidelines are provided, emphasizing the use of protective gear to prevent skin and eye irritation.
A primer like LANGUAN 690 balances water absorption, seals air voids, and provides a bonding bridge to prevent the self-leveling compound from peeling or cracking.
Dilution depends on the substrate: Use undiluted for dense smooth bases, 1:1 for standard concrete, and 1:3 for highly porous cement mortar or gypsum.
Yes, it is applicable for interior wall bases, especially for gypsum plastering on dense concrete walls using a 1:3 dilution ratio.
Apply evenly using a brush or short-nap roller. You must wait for it to be fully dry before proceeding with the how to use self leveling concrete process.
All brushes and rollers should be cleaned with clean water immediately after use and before the product cures to avoid waste.
Store in an indoor, cool, dry, and frost-free environment. Unopened 20L pails have a shelf life of 24 months.
