Application Instructions:
Substrate Quality / Pre-treatment: Surface must be clean, dry, and free of contaminants. Pull-off strength should be ≥ 1.5 N/mm². Priming is required (Sikafloor 160/161 or Sikadur 31/33 depending on application).
Mixing: Premix Part A, add pigment, mix. Add Part B, mix. Gradually add Part C & D (aggregate) using a double paddle mixer for at least 2 minutes. Mix full units only.
Application: Apply the mixed mortar onto the primed substrate while the primer is tacky. Compact to the desired thickness and finish with a coving trowel or steel float. Top coats (Sikafloor 31 PurCem) can be applied for a smoother finish.
Cleaning of Equipment: Clean tools with Thinner C immediately after use. Hardened material can only be removed mechanically.

Colour Accuracy Disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
