  3. Concrete, Cement, Block, Pavers, Synthetic Wood

    Use SEMCO Nu-Lift Cleaner and Stone Soap to remove any mineral deposits or efflorescence • If there is any oil or grease, use SEMCO Power Cleaner and Nu-Lift Cleaner to strip surface of any oil or grease

  4. Metal, Aluminium

    Use SEMCO Nu-Lift Cleaner and Stone Soap to chemically etc the surface of the metal for optimal bonding

  5. Surface Preparation
    • Sweep all debris off surface to ensure proper bond. Clean up with water.
  6. Roller / Brush Application
    • Use a 1/2 nap roller. Allow any pre-treated areas to dry to the touch. Apply a thin coat of Liquid Membrane with brush or roller over substrate including pre-treated areas. Apply another thin coat of Liquid Membrane over the first coat of Liquid Membrane. Let topcoat dry to the touch, approximately 1–2 hours at 70 °F (21 °C) and 50% RH. When last coat has dried to the touch, inspect final surface for pinholes, voids, thin spots or other defects. Liquid Membrane will dry to a lighter color when it’s dry to touch. Use additional Liquid Membrane to seal the defects. Required thickness is 40 mil
  7. Sprayer Application
    • The sprayer being used for the application of Liquid Membrane should be capable of producing a minimum of 2,500 psi (17.2), maximum of 3,300 psi (22.8 MPa) with a flow rate of 0.95 to 1.6 GPM (3.6 to 6.0 LPM) using a 0.521 or a 0.631 reversible tip. Keep the unit filled with Liquid Membrane to ensure continuous application of liquid. The hose length should not exceed 100’ (30 m) in length and 3/8” (9 mm) in diameter. Required thickness is 40 mil
    • Additional Info
    • For clean up use warm water to clean brush or roller right after use. 
    • For optimal bonding we highly recommend preparing the surface as mentioned above for best results.
    • Suitable for light foot traffic.For heavy foot traffic or vehicle traffic, we recommend using SEMCO Titan Shield.
    • Stir up the product well before use in order to mix up the color pigments.
    • Avoid application in direct sun light in the afternoon or temperatures of over 85F as it might cause the product to dry too fast before it can adhere to the substrate
    • For applications where the product is fully submerged,3 coats @20mil thickness per coat is required and  allow a curing time of minimum 6-7 days.
    • Coverage may vary depending on porosity of the substrate and also the thickness of coat being applied.
    • For applications where SEMCO Liquid Membrane is applied on pool plaster, extended curing times might occur as plaster holds more moisture which needs to breath out first. A slight color change may occur when being in contact with water when the product has not fully cured yet. This however will not affect the performance of the SEMCO Liquid Membrane
