Acrylate Spray Membrane Waterproof Coating

Two-Component A & B Set

Caberry acrylate spray membrane waterproof coating is a two-component rapid curing spray-on waterproof system. Featuring fast installation, seamless membrane formation and environmental friendly formula, it is the preferred solution for complex structures and tight-schedule projects. It suits scenarios requiring high waterproof reliability and variable substrate conditions, such as tunnels and underground structures.

• Rapid construction speed, ideal for tight construction schedules.
• Forms fully seamless integral waterproof membrane after spraying.
• Eco-friendly formula, low pollution and safe for confined underground spaces.
• Built-in penetration adhesion, primer-free application.
• Excellent adaptability for irregular, complex structural surfaces in tunnels and basements.

1. Substrate preparation: Remove laitance, oil stains, repair holes and defects. Substrate strength ≥ C15, no standing water.
2. No primer needed: Material has self-penetrating bonding property.
3. Mixing: Two components mixed mechanically at specified ratio (A:B = 1:1), stir evenly without lumps.
4. Spraying equipment: Special airless sprayer, working pressure 20–25 MPa, nozzle diameter 2–4 mm.
5. Spray procedure: Spray evenly onto vertical substrates. First coat: 0.3–0.5 mm. Cross-spray 2–3 layers, total thickness: 1.2–2.0 mm. Interval between each layer: 10–15 minutes.

• Form: Two-component liquid, Component A + Component B
• Package: Blue plastic drums for A and B separately
• Storage: Sealed, cool shaded warehouse; avoid freezing, high temperature and direct sunlight
• Trade Terms: EXW, FOB Guangzhou, CIF, DDP available

Q: Must it be sprayed with special airless equipment?
A: Yes, dedicated airless spray equipment is required for proper instant mixing and film forming; manual brushing is not recommended.

Q: Can this be used on wet substrate?
A: No standing water allowed; damp substrate is acceptable if no free water, but surface must be stable and solid.

Q: What is the difference compared with modified asphalt bridge coatings?
A: Acrylate spray membrane is mainly for tunnels and underground works, fast-curing seamless film; FYT‑1 / PB series are asphalt-based, mainly for bridge decks under hot asphalt overlay.

Q: Is 1:1 mixing ratio fixed?
A: Follow factory label ratio; 1:1 is the standard mixing ratio shown in the construction guide.

Q: Can you provide English TDS and MSDS?
A: Yes, complete English technical documents ready for customs clearance and overseas tendering.
