• VOC-Compliant. Meets SCAQMD Rule 1113 when using SikaWall Non-VOC Colorants.

12 months from date of production if stored properly in original, unopened and undamaged sealed packaging.

Store dry, off ground and protect from rain and moisture.

Dry in approximately 1 hour depending upon temperature, humidity and substrate. High humidity and low temperatures extend drying time. Can be recoated after drying.

Dependent on the condition of the substrate, method of application, amount of water used per bag and number of applications. Approximate coverage when two coats are applied is: 320-480 ft². (30-45 m².) per 12 lbs (5.4 kg) bag.

SPRAYER SPECIFICATIONS:

Airless Sprayer:

• SikaWall® Allegro II Cement Coating Sprayer Requirements: when spray applying coatings it’s important that the equipment being used can provide the output to support the selected tip, it’s always best to have a sprayer with a higher output than the tip because as the tip wears, its orifice size becomes bigger and the material flow rate increases. Always test by spray applying the material on the surface while adjusting the fluid pressure to achieve proper fluid delivery and atomization.
• Textured Surfaces: Minimum Graco XR7 Airless Sprayer (or equal) with a minimum 0.015 and maximum 0.019 tip-reversible for quick unclogging, referenced as 519 or 619. Flow Rate 0.31 GPM. / Supports tip size up to 0.017 in. / Operating pressure 3000 psi (19 MPa).
• Smooth Surfaces: Minimum Graco 390 Airless Sprayer (or equal) with a minimum 0.012 and maximum 0.015 tip-reversible for quick unclogging, referenced as 512 or 615. Flow Rate 0.47 GPM. / Supports tip size up to 0.021 in. / Operating pressure 3300 psi.

Conventional or HVLP Sprayer Requirements:

• Pressure Fed (Pressure Pot) sprayers require adequate air compressor support; CFM requirements based on the length of air & fluid delivery hoses and material viscosity can vary greatly. HVLP spray gun with 1.4 to 1.8 mm diameter fluid tip nozzle, tank pressure needs to be approximately 25 psi. Gun air pressure needs to be approximately 45 psi. Conventional spray gun with a 1.4 to 1.8mm fluid tip nozzle, tank pressure needs to be approximately 30 psi. Gun air pressure needs to be approximately 60 psi.
• Strain the SikaWall® Allegro II Cement Coating material through a suitable paint strainer into a clean 5-gallon pail or the spray equipment tank to be used. Agitate material frequently during application to avoid settling

• Surfaces must be sound, clean, dry, and free of dirt, foreign material, and any residue which may affect the ability of the SikaWall® Allegro II Cement Coating to bond to the surface.
• Remove surface contaminants such as form release agents or bond breakers dust or dirt without damaging the substrate.
• NOT recommended for application over painted, sealed, wood or metal surfaces.
• Ambient and surface temperatures must be 40ºF (4ºC) or higher during application and for at least 24 hours or until dry.
• For additional options, contact Sika Facades Technical Support.

• Read the entire label before using this product.
• Use clean equipment for mixing and preparation. While stirring with a drill at 400–500 rpm (rust free mixing paddle), slowly add the SikaWall® Allegro II Cement Coating powder to 2-½ gallons of cool-clean potable water.
• Shake color well, dispersing the liquid pigment before adding to the pail.
• While stirring, add the selected SikaWall Color Bottle liquid color to the pail. Make sure all of the color is added by rinsing out the color bottle with water (1/3 of the bottle’s volume) shake well, add it to the pail and mix until a uniform consistency and color is obtained.
• Let the material sit for approximately 10 -15 minutes and remix to ensure the product and color are well dispersed. NOTE: Water content will vary based on surface conditions and type of equipment used. Add additional water if or as required for the application and re-stir the material. The amount of water used should remain constant throughout the job to prevent color variations. If using a professional grade Airless or HVLP Gun sprayer, less water is required. For application over absorbent surfaces and/or with the use of a hand-pump (low pressure) compressed air tank sprayer, up to one additional gallon of water can be added for a maximum of 3-½ gallons of water per 12-lb. bag of SikaWall® Allegro II Cement Coating.
• Strain the SikaWall® Allegro II Cement Coating material through a suitable paint strainer into a clean 5-gallon pail or the spray equipment tank to be used. Agitate material frequently during application to avoid settling.

• SikaWall® Allegro II Cement Coating is spray applied, for the best results, always apply SikaWall® Allegro II Cement Coating to the entire project or wall section, top to bottom and corner to corner or to a prominent architectural break.
• Hold the nozzle approximately 18 inches from the wall when spraying; when using a circular pattern tip use a circular motion, or alternate vertical and horizontal motions when using a fan pattern tip. Avoid runs.
• Two coats are required to ensure complete coverage, unusually coarse, smooth and or dense surfaces may require additional applications. The first coat is a light coat that acts as a primer. Allow the first coat to set-up (approximately 15-20 minutes) before applying the second coat. On smooth surfaces, a sealer is recommended to prevent possible marring and increase scratch and stain resistance. SikaWall-4910 Clear Seal can be used on all surfaces coated with SikaWall® Allegro II Cement Coating cured a minimum of 24 hours. NOTE: The use of a sealer prohibits recoating the sealed surface with SikaWall® Allegro II Cement Coating.

SikaWall® Allegro II Cement Coating cures by drying, do not moist cure. Complete curing in 24 hours under normal conditions.
