SikaWall® Perma-Flex Stucco Acrylic

15 months.

Protect from direct sunlight and freezing at all times.

Do not stack pails more than 3 pails high

24 hours under normal conditions. High humidity and low temperatures extend drying time.

Depending on the condition of the substrate and method of application, approximate coverages per pail are:

• Smooth Aggregate size: 0.5mm 280-300 ft2 (26-28 m2)
• Swirl Aggregate size: 1.5mm 120-135 ft2 (11-12.5 m2)
• Fine Aggregate size: 1.0mm 150-165 ft2 (14-15 m2)
• Coarse Aggregate size: 1.5mm 110-125 ft2 (10-11.5 m2)

Remove surface contaminants such as dust or dirt without damaging the substrate. For previously painted surfaces, 100%  of all loose and chalking paint must be removed, and any glossy surfaces dulled. New concrete must be clean and cured a minimum of 28 days. Check concrete surfaces for alkalinity and treat. Any form release agents or bond breakers must be removed. 

Portland Cement Stucco  must be clean and cured a minimum of 7 days or in accordance with Sika Fastwall Specifications.  Sika Facades recommends the use of SikaWall tinted primers to enhance the appearance and uniformity of the finish, improve coverage and reduce the chances of efflorescence. This is especially true when using dark colors or finishes with a large aggregate.

• Use clean equipment for mixing and preparation.
• SikaWall Color Bottles " Add liquid color to the pail of finish. Make sure all of the liquid colorant  is added by rinsing out the color vial with water (1/3 of the vial’s volume) into the pail.  
• Add the amount of water needed (up to a maximum of 16 oz. per pail) to achieve finish texture. To avoid color variations, add the same amount of water to each pail of finish 
• Mix to obtain a homogeneous consistency using a heavy-duty 1/2-in. (13mm) drill with a rust free paddle at 400-500 rpm. Avoid air entrainment by over mixing.  Caution should be used to make sure no pigment remains on the edges of the pail , all pigmment must be properly mixed for color consistency . 

• Read the entire label before using this product.
• Always maintain a wet edge and work to corners or joints. For best color consistency, use finish with the same batch number within a wall section.
• Keep container closed when not in use.
• Use a clean stainless steel trowel and apply a uniform coat the thickness of the largest aggregate size of the finish

Texturing LaHabra Fine, Swirl and Coarse Finishes:

Use a clean plastic float or a stainless steel trowel. A plastic float will roll the large aggregates more than a stainless steel trowel. Continuously dry clean the plastic float or steel trowel while texturing. Use consistent pressure and motion to achieve the desired texture.

Texturing Smooth Finish:

Optional: Level stucco brown coats with Stucco Level Coat and let dry prior to finish application. Smooth Finish cannot generally be floated. Texture will be “as troweled.” Smooth Finish can be troweled smooth to simulate the texture of limestone. 

For smoothest application, apply in two tight coats. Allow first coat to dry enough that it will not be disturbed during application of the second coat. When second coat is partially dry, trowel to desired smoothness. Light, consistent misting with water during smoothing will increase smoothness. Variations in color tint and smoothness should be expected.

Spray application:

To achieve consistent texture, spray application must use consistent motion, pressure, distance and spray angle. A job-site mock-up for spray application is advised.

Sika USA recommends the use of SikaWall tinted primers to enhance the appearance and uniformity of the finish, improve coverage and reduce the chances of efflorescence.

Water soluble prior to drying. Clean tools and equipment with water prior to drying.
