About
The SEMCO Liquid Membrane™️ is a single component waterproofing and anti-fracture membrane. It is a self-contained elastomeric fluid suspended in a copolymer adhesive, this revolutionary blend enables easy application while providing excellent bridging, and waterproofing

THE SOLUTION

Specs
- Ready to use waterproofing and crack-prevention
- Coverage : 200 - 250 sq ft /gallon @ 2 coats (20mil each)
- Easy to apply : with 1/2" woven nap roller or brush
- Substrates: Concrete, Pylwood, Stone, Tiles, Interior&Exterior Cladding, Metal&Aluminium, Drywall boards, ICF blocks
- UV-Stable : Suitable for exterior applications
Benefits / Features
- Waterproofing Concrete and Wood substrates
- Repair cracks up to 1/4" wide
- Repair control joints and cracks wider than 1/4"
- Stabilization of detoriating and crumbling surfaces
ADHESION
CRACK BRIDGING
Instructions
- Surface Preparation
- Sweep all debris off surface to ensure proper bond. Clean up with water.
- Roller / Brush Application
- Use a 1/2 nap roller. Allow any pre-treated areas to dry to the touch. Apply a generous coat of Liquid Membrane with brush or roller over substrate including pre-treated areas. Apply another generous 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 bright orange color when it’s dry to touch. Use additional Liquid Membrane to seal the defects. Required thickness is 40 mil
- 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

SUBSTRATES
✔️Concrete
✔️Plywood
✔️Exterior/interior cladding
✔️Residential, industrial and commercial
BENEFITS
✔️ACTIVE ADHESION : Integrated chemical adhesion enables mechanical cross-linking to the applied surfaces, creating a perfect bond for long lasting protection.
✔️WATERPROOF MEMBRANE : Low VOC waterproofing that allows you to proceed with your finish within 2 hours of application enabling a speedier project completion.
✔️ELONGATION WITHOUT BREAKING : Up to 400% stretch and elongation providing future crack suppression for years to come. Stabilizes wood substrates to receive surface finish products.
TOOLS NEEDED
