- Pre-Application
- Before applying product, test in an inconspicuous area for desired results. For any questions regarding application, contact ChemSystems, Inc.
- Prepare surfaces by removal of laitance, grease, and foreign matter, etc. Repair damaged concrete or provides sloping using a repair mortar or underlayment. Prime with Waterproof Membrane, cut 50% with water. Allow to dry.
- Apply Waterproof Membrane to thickness sufficient to produce 25 mils d.f.t., 12.5 mils dry per coat, two coats (incorporate fabric reinforcement as option for thickness of 30 mils).
- Apply cementitious coating protection course (optional). Conduct water test of finished installation.
- Optional thickener additive available for vertical applications
- Not recommended for application over expansion joints or seismic joints.
- All loose or unsound concrete must be removed and repaired
- Application
- Applied by roller, trowel, spray or squeegee, Waterproof Membrane offers water protection together with excellent adhesion and is more resistant to impact than most membranes. It is applied to floors and molded up onto bases, over curbs, etc. without the use of any adhesive other than its own composition.
- Among the surfaces Waterproof Membrane can cover are concrete, tile and metal. For wood surfaces, consult ChemSystems, Inc.
- Cold Temperature Flexibility: May be folded double, maintains stretch-ability when immediately removed from freezer.
- Surface Protection and Maintenance
- Protect materials from excessive heat and cold and regularly check wet film thickness with mil gage and monitor consumption to ensure correct application thicknesses and rate are obtained.
- For maximum sheen and cleanability, floor should be routinely treated with conventional maintenance finish followed by ordinary buffing
