Product Description: Orco Blended Water Stop is a 2 component cement based waterproof coating designed to seal masonry and concrete surfaces. It may be used above or below grade. Because its ingredients are similar to those in concrete, it cures to become part of the substrate. Water Stop is mixed with Orco Blended Acrylic Glue and water at the job site. Acrylic Glue improves the bonding, waterproofing and curing properties. Orco Blended Water Stop is available in natural gray and special order colors. Uses: Waterproof & Damp proof Below Grade - Foundation Walls Planters Retaining Walls Tunnels

Above Grade: Over block, concrete or plaster. Behind brick, stone, tile or marble
Water Retaining Structures: Swimming Pools, Fountains, reservoirs, and sewer lines

Advantages:

• Cures to become part of the substrate
• Durable surface-Long life expectancy
• A breathing surface that will not blister
• Water based for easy application and clean up
• Easy disposal of bags - no toxic cans
• Waterproof & decorate with one application
• Salt Resistant
• Withstands constant exposure to water

Packaging: Orco Blended Water Stop is available in 60lb paper sacks. Orco Blended Acrylic Glue is available in 1-gal bottles & 5 gal pails.

Coverage: 60lbs cover approximately 225 sq. ft per coat - 2 coats required.

Surface Preparation: All surfaces must be structurally sound, free of oil, dust, efflorescence, curing compound, or bond inhibitors. Clean surfaces by wire brush or sand blasting. Chemically remove any efflorescence, grease or oil. Smooth surfaces should be roughened or etched. Repair all cracks and holes with Orco Blended Water Stop. A cant should be formed at the base of all footings and walls with Orco Blended Hydraulic Cement prior to applying Water Stop. Dampen wall prior to application. Dense concrete should be wet at least twice. If the product begins to pull on application, this is an indication that the surface is not properly wet.

Mixing: Add one part Orco Blended Acrylic Glue to three parts water and mix thoroughly (1/2 gal Acrylic Glue to 1-1/2 gal water per 60lb bag will produce a pancake batter consistency). Add the mixing liquid to Water Stop and mix to smooth consistency. Do not use a high-speed drill. Allow coating to sit for 15 minutes and remix without adding water. For trowel applications the mixing liquid should be approximately 1-1/2 gallons per 60lb bag. For surfaces exposed to difficult conditions, (sewers, dense concrete, pools), the ration of Acrylic Glue to water should be increased to 1:1.

Placing: Apply the first coat on Water Stop with a fiber brush, scrubbing well into the damp wall, filling all pores. Always keep a wet edge. Allow first coat to cure for 12 hours before applying second coat. The second coat should be laid on the surface. Do not allow first coat to become contaminated prior to application of second coat. For thicker trowel applications, apply first coat by brush and second coat by trowel at a maximum thickness of 1/8".

Curing: when surface becomes hard, fog spray with clean water. Keep surface damp for three days. Proper curing is essential in extremely hot or windy conditions.

Limitations: Do not apply when temperature is below or expected to fall below 40 deg F prior to cure. Substrate must be sound. Orco Blended Water Stop is not designed to seal crack which develop after application.
