Fields of application
Suitable for surface regulation and reconstruction works on missing sections and cavities, especially in works involving structural renovation of worn concrete. Volumetric reconstruction of concrete cover on structures in reinforced concrete or prefabricated ashlars.
Allowed supports
Prefabricated concrete
Bricks
Preparation of supports
Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface". 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).
Mode of use
Pour about 2/3 of the mixing water into the mixer, add Repar Tix Speedy HP and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 16 - 18% of the weight of the bag.
Having finished mixing, immediately use the product for the works necessary, paying attention to its fast hardening. You are advised to use a little product at a time, only the quantity usable within 10 minutes after mixing (attention, the ambient temperature can also considerably affect the hold time of the product!).
