Use fields
Repairs, reconstructions and anchorages for fast re-use, in road works and in concrete, even in severe weather conditions and at low temperatures. Quick anchoring of metal partitions and elements,grouts, equipment installation, street manhole covers, etc.
Preparation of supports
The surfaces should be clean and free of any soiling, crumbling and non-adhering parts, dust, salt efflorescence, milt of cement etc., free of oils, greases, properly hardened and compact. An adequate roughening of the surfaces by scarifying, sandblasting etc. is always necessary in order to obtain the maximum adhesion values to the substrate. The optimal values are obtained with high pressure hydro-scarification. Bare the irons undergoing disruptive oxidation or deeply oxidized, removing the rust of the exposed irons (by sandblasting or abrasive brushes).
Use method
Given the peculiarities of the product, it is advisable to adjust the mixing water as required from time to time, taking care not to make the product too fluid. Pour about 15% of water on the weight of the bag in the mixer, gradually add the product and the water still required, until the desired consistency is obtained. Continue to mix until a homogenous lump-free mixture is obtained.
