Fields of application	Restoring the concrete to its originally specified shape and function by means of mortar applied manually or by projection (Principle 3 CR, method 3.1 and 3.3 acc. to EN 1504-9). Restoring the passivation by increasing the coating with cement mortar and replacing the contaminated or carbonated concrete (Principle 7 RP, methods 7.1 and 7.2 acc. to EN 1504-9) Non-structural repair of all types of elements subjected to aggressive environments such as: Columns, beams, joists, wrought iron edges and slabs, made with anti-sulphate cements. Chimneys, cooling towers or bays, etc. Decanters, digesters, purifying plants, etc. Tunnels and buried structures in aggressive environments. structures in saline environments or in contact with sea water. Execution of high-performance works High-performance coating Repair and recovery of volumes on facades, balconies .. Superficial regularization in pools, tanks, wells … Execution of half-reeds and regularization, before execution of waterproofing systems Repair and regularization in ceilings Regularization of substrates before laying ceramic tiles or light flooring
propiedades	Sulphate resistant. High thixotropy, applicable in thicknesses of 2 to 25 mm, manually or by projection. (50 mm in two coats) High compatibility with concrete and brick substrates. No shrinkage and reinforced with fibres, it does not crack. Its accurate granulometry provides a cosmetic finish similar to that of the original concrete. Free of chlorides, its high pH protects against the corrosion of metal elements, such as rebars, anchorings, etc. Excellent adhesion strength to concrete, even on substrates that are not very porous. Impermeable. Applicable indoors and outdoors. High resistance to carbonation and the freezing-thawing cycles. Can be applied by projection. It withstands temperatures between -50 ºC and +500 ºC. Excellent workability.
