APPLICATION STEPS
Substrate Preparation
Confirm waiting /overcoating time has been achieved on the previously applied system base layer. The base layer must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and loose material. If dust exists on the surface, it must be completely removed before application of the product, preferably by vacuum extraction equipment.
If the maximum overcoating time of the base layer is exceeded, the surface must be lightly abraded using light abrasive manual tools or mechanical equipment to roughen the surface. Depending on the type of base layer, a solvent wipe may also be required. Finally, completely remove all the dust by vacuum extraction equipment.
Mixing
Prior to mixing all parts, mix separately Part A (resin) using an electric single or double paddle mixer and stirrer (300 to 400 rpm) or other suitable equipment. Mix liquid and all the coloured pigment until a uniform colour / mix has been achieved. Add Part B (hardener) to Part A and mix Part A + B continuously for 3,0 minutes until a uniformly coloured mix has been achieved. Mix full units only. Mixing time for A+B = ~3,0 minutes.
Application
Apply mixed product in 1 coat by roller, brush or spray equipment to achieve a consistent thickness and required surface finish.
Cleaning of Equipment
Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically or with a proprietary paint stripper.

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.
