Application Instructions:
Equipment: Centre shafted roller frame (min 350mm width), roller nap length (min 15mm).
Mixing: Condition materials to 18-25°C. Add pigment to Part A (15s), add Part B (30s), add Part C (15s while mixing). Mix for 2 minutes until homogeneous. If needed, add accelerator (30s mix). Use immediately.
Application: Apply evenly with the recommended roller. For textured HB-22, pour in lines, apply with a rubber squeegee, and lay off excess with rollers (at right angles for even distribution). Discard mixing buckets every 3-4 mixes and roller sleeves every 30 minutes at 20°C. Consider a second coat for lighter colors or Broadcast B1 texture.
Cleaning of Equipment: Clean equipment with Sika Colma Cleaner.

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.
