Application Instructions:
Substrate Quality / Pre-treatment: Concrete shall be free from dust, loose material, surface contamination. Remove delaminated, weak, damaged concrete. Pre-wet concrete thoroughly. Steel reinforcement: remove rust, scale, mortar, clean to SA 2 (ISO 8501-1) using abrasive blast cleaning or high-pressure water-blasting.
Mixing: Mix with a low speed (< 250 rpm) electric drill mixer. Shake components A and B. Pour A and B into a vessel and mix for 30 seconds. Slowly add component C while mixing. Mix all three for a minimum of 3 minutes, minimizing air entrapment. Let stand for 5–10 minutes until brushable consistency. DO NOT ADD WATER.
Application:
-
As reinforcement corrosion protection: Apply first layer (~1 mm) to cleaned reinforcement with a medium hard brush or spray gun. Apply the second layer when the first is hard to the fingernail (~2–3 hours at +20 °C). Apply subsequent repair mortars wet on dry.
-
As a bonding primer: Apply to prepared substrate with a medium hard brush or spray gun, ensuring it fills all pores (minimum 0.5 mm thickness). Apply subsequent repair mortars wet on wet. Protect freshly applied material from contamination and rain.
Curing Treatment: Protect fresh mortar from rain until set.
Cleaning of Equipment: Clean all tools with water immediately after use. Hardened material can only be mechanically removed.
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.
