If you have any wax or existing coating we recommend using SEMCO Power Cleaner and Stone Soap to strip it off. • Or use 60 grit sandpaper to lightly sand the surface to take off any dirt or loose coating

Use SEMCO Nu-Lift Cleaner and Stone Soap to remove any mineral deposits or efflorescence • Remove any loose paint or coating

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

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

Needs to be removed completely prior to application

• Sweep all debris off surface to ensure proper bond. Clean up with water.

• Use a 1/2" nap roller. Allow any pre-treated areas to dry to the touch. Apply a coat of Liquid Membrane(0.015 inches per coat) with brush or roller over substrate including pre-treated areas. Apply another coat of SEMCO Liquid Membrane™️ over the first coat of SEMCO 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. SEMCO Liquid Membrane™️ will dry to a lighter shade when it’s dry to touch. Use additional SEMCO Liquid Membrane™️ to seal the defects. Required thickness is 40 mil

• The sprayer being used for the application of SEMCO 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 SEMCO 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.
• 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
• Suitable for light foot traffic.For heavy foot traffic or vehicle traffic, we recommend using SEMCO Titan Shield.
• It can not be applied to wet substrates or substrates still containing moisture, else it will not cure correctly and stay tacky. Max. rest moisture in substrate can be up to 3%. If you are unsure about the moisture content, have it measured prior to application.
• For applications where the product is fully submerged, 3 coats @20mil each is required and allow a curing time of minimum 6-7 days.Also application must coat entire surface to above the waterline.
• Application on non porous surfaces such as metal or fiberglass : Apply thin coats as this will allow for the product to cure faster.
• Cure times are displayed in our curing chart. However if coats have been applied too thick, the surface might feel tacky. This is a sign of trapped moisture. If you have left over product, apply a very thin coat over the entire surface. The surface needs to be fully cured and hard before being fully submerged.
• 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.
