The product will be dry to the touch within 1 to 3 hours. After application the surface must be protected from strong winds and sun until the product is dry (3-6 hours), it must also be protected from rain until the end of the cure which lasts between 12 and 36 hours depending on temperature and humidity. 

It is necessary to calculate a minimum of twelve (12) hours between each coat.

Approximately 32.2 m² to 48 m² (360 ft² to 520 ft²) per 15.14L (4 US gal) per coat of SikaWall®-485 MP Primer Plus. The consumption indicated is a reference value on a smooth surface. Exact values can only be determined by painting test areas on the structure to be coated using tools and techniques that will be used for the final application.

Refer to the relevant Product Data Sheet (PDS) for each SikaWall®-485 products for more consumption references.

SikaWall®-485 MP Primer Plus can be applied by: 

• Brush: Use a natural bristle or nylon/polyester 
• Roller: Use a 13 mm to 19 mm (½ into ¾ in) nap synthetic roller cover 

Application by brush is best for crack filling as the material can be worked into all surfaces well. For equalizing appearance application by roller is recommended.  

Mix SikaWall®-485 MP Primer Plus to ensure uniformity using a slow speed (300 - 450 rpm) drill fitted with a Jiffy-style paddle. Mix for about three (3) to five (5) minutes until a homogeneous mixture is obtained. 

If it is planned to use SikaWall®-485 MP Dilution as a diluent with SikaWall®-485 MP Primer Plus, mix each product separately using a drill firstly. Then, add SikaWall®-485 MP Dilution to SikaWall®-485 MP Primer Plus and stir all materials together. Always have accurately measured materials. Do not exceed the recommended amounts.  The recommended percent dilution is an "added by volume" rather than a ratio, as a rule: 

A ratio of 10 % is equivalent to: 

• 1.5 L (0.4 US gal) of SikaWall®-485 MP Dilution for 15.14 L (4 US gal) of SikaWall®-485 MP Primer Plus 

The paint should be stirred regularly in its container before & during application to avoid segregation of constituents.

It is important to work ‘’wet-on-wet’’ maintaining a wet edge. Work corner to corner or use an architectural feature as a starting and stopping point. Stirred regularly in its container before & during application to avoid segregation of constituents.

IMPORTANT NOTE:  Always carry out an application test in an inconspicuous to verify substrate conditions and to  confirm application method, consumption rate and coverage. Best practice suggests that the selected area is acceptable to all parties involved and that it is representative of the area to be eventually pre-treated with SikaWall®-485 MP Primer Plus

Clean all tools and application equipment with water immediately after use. Once dried/cured, material can only be removed mechanically.
