PAREX® AquaSol™ Coating

Two (2) years, when properly stored in original container.

• Store in a cool, dry place protected from freezing, extreme heat and direct sun. Store at no less than 40°F (4.5°C).
• Do not stack pallets.

• EIFS
• Stucco
• Acrylic, Hydrophobic and Cementicious Textured Finish
• Unit Masonry
• Concrete
• Existing Coatings

Under average conditions of 70 °F (21 °C) and 50% Relative Humidity

• Typically dry to touch within 2 to 4 hrs.
• To recoat, allow minimum of 6 hours drying time per coat Lower surface or air temperatures and higher relative humidity will extend the drying time.
• Protect coating from rain or other precipitation and temperatures less than 40°F (4.5°C) for a minimum of 24 hours and until dry.

900-1,400 ft2 at 5-8 wet mils (single coat)
Some applications may require two coats.
Coverage may vary depending on the texture, porosity and color of the existing substrate.

Substrates must be clean, dry, sound and free of loose material, releasing agents, paint, efflorescence, contaminants and other coatings. Cracks or voids must be filled with Sika Thorocoat®-748 or appropriate, compatible material to provide a solid substrate prior to application of PAREX® AquaSol™ Coating.
Ensure patching material is dry prior to application of coating. If SikaWall-15 Tinted Primer is used, ensure primer is dry to the touch prior to application of coating.
 

Note: Apply a 4' x 4' (1.2 m x 1.2 m) test area to verify acceptable color and adhesion before proceeding with any project. Adhesion shall be measured by ASTM Test Method D 3359 Procedure A, with a value of 4A or greater.

• Weathered PAREX® AquaSol™ Coating: recoated with PAREX® AquaSol™ Coating or acrylic coatings after cleaning the surface with a household detergent and rinsing with water. Surface must be thoroughly rinsed with clean water to remove all traces of detergent. Check surface for any signs of beading, if present repeat cleaning process until gone.
• Allow surface to dry completely before recoating. Recoat within 48 hours, weather permitting.
• Existing Coatings and Finishes: Check adhesion of old coatings according to ASTM D 3359, Measuring Adhesion by Tape Test Method A. Remove any blisters or delaminated areas and sand edges to smooth rough areas and provide transition to old paint areas. If needed, apply SikaWall-15 Tinted Primer. Do not apply over existing siliconized coatings. 
• Unit Masonry: Allow to cure prior to application of primer or coating. When needed, apply a levelling coat of Sika Facades base coat to provide a smooth surface and minimize the likelihood of mortar joint read through.
• Concrete Surfaces: New concrete and masonry must be clean and cured a minimum of 28 days. Check concrete surfaces for alkalinity and treat if necessary. Remove any form-release agents or bond breakers prior to applying the coating. 
• Stucco (New): Allow to cure a minimum of 7 days prior to application of primer or coating.

Mix the contents of the coating pail with a low speed drill and paddle mixer until thoroughly blended.

• Additives are not permitted.
• Close container when not in use.
• Clean tools with soap and water immediately after use.

One coat application: First apply SikaWall-15 Tinted Primer per product bulletin instructions then apply one coat of PAREX® AquaSol™ Coating.

 
Two coat application: Allow the first coat to dry prior to application of the second coat.

• Maintain proper uniform wet-film thickness during application to ensure the performance characteristics desired.
• Care should be taken when applying it to heavily textured substrates. Fluted masonry and raked joint substrates will require hand detailing to ensure an even and successful application.
• For uniformity of color and texture, application techniques must be consistent throughout the project.
• Confirm sealant adhesion prior to application of sealant primer and sealant to PAREX® AquaSol™ Coating.

 
Roller
Apply coating with a 3/8"-1/2" (10-13 mm) nap roller. Completely saturate the roller and keep it loaded with the coating to build the required mil thickness, never dry roll. Cross roll, maintaining a wet edge, to achieve uniform thickness. Backroll in one direction for a consistent appearance.
 

Spray
Airless spray equipment is available for spraying PAREX® AquaSol™ Coating. Reference Sika Facades Coatings Spray Equipment Recommendations Technical Bulletin or contact equipment manufacturer for further recommendations. Backrolling in one direction after spray application is recommended to achieve uniform texture and film thickness.
 

Brush
Application by brush is recommended only for small inaccessible areas, e.g., on touch-ups. Use only a nylon brush.
