Instructions for Use
Preparation
All Surfaces which are to receive the coating, must be free from oil, laitence, grease, wax, dirt or any other form of foreign matter which could aect adhesion. Typically concrete surfaces can be cleaned using high pressure water jet or grit blasting. Predampen the substrate surface with water. High porosity substrates will require more dampening than dense substrates. Any condensation should be removed using a sponge. Any running water should be stopped with RAK Quick Seal.
Supports
The support must be clean and free of oil, grease, dust and any other unwanted residual materials. The support to be treated should be thoroughly wet prior application.
Storage
Store out of direct sunlight, Protect from rain
Application
RAK Creete is supplied in pre-measured containers and should be mixed on site using a clean container. Slowly add the powder to the liquid & mix using a slow speed drill fitted with a suitable paddle. Do not mix more material that can be used within one hour. The apperance of the mixture will be a creamy coat, which can be applied with a brush. Apply the first layer with sucient thickness to cover the holes, cracks, etc. completely. The approximate consumption will be 1.2 kg/m. Once the first coat is dry, apply second and third coats in order to achieve the required thickness at an average consumption rate of 900 g – 1 kg/m. It is recommended that each coat should be a minimum of 1mm thickness.
Shelf Life
Up to 12 months if stored under 30°C away from direct sunlight
Health & Safety
As with all chemical products, caution should always be excercised. Protective clothing such as gloves and goggles should be worn (see packaging for specific instructions). Treat any splashes to the skin or eyes with fresh water immediately. Should any of the products accidentally swallowed, do not induce vommiting but call for medical assistance immediately. Ensure the container is available for the medical attendant to examine any relevant instructions and contents details. Reseal all containers after use and ensure product is stored as instructed on the safety section of the labeling.
