Mr Crystal is a cement based waterproofing compound that chemically reacts with moist cement based substrates forming insoluble crystals in the capillary tracts of the substrate waterproofing the concrete yet still allowing the surface to breathe
Mr Crystal comes as a full kit to enable you to repair your concrete tanks and troughs with ease.
Mr Crystal is applied to the surface of the concrete. Within concrete are millions of tiny voids. Mr Crystal migrates through these voids by osmosis and capillarary action, generating in-soluble crystals as it travels.
Mr Crystal is in fact a catalyst, which causes your existing concrete to grow in-soluble crystals. This means you have a large amount of material in the structure, which can generate in-soluble crystals without adding material that will expand cracks.
Mr Crystal is stimulated by the by-products of your existing concrete and hydration. This means, each time water is present within the substrate, Mr Crystal will activate.
Mr Crystal protects the reo in two ways. Firstly, it protects the reo from the elements by excluding water and air from reo tract. Secondly, Mr Crystal chemically protects the reo by restoring the alkalinity of the substrate thus reducing the acidity of the environment in which the reo is located.
Mr Crystal is designed to work on commercial grade concrete that has basic structural integrity. To achieve success with this product you must ensure that, structure is made of concrete containing building cement (commonly known as Portland cement). Movement must be controlled by adequate foundations and reinforcement and finally the structure must be treated according to the enclosed directions for use.
1 Kilogram will treat 4.5 metres of crack.
